The input to output ratio is accurate to 0.1dBu.The Hard Knee and Soft Knee allow for instant or gradual compression once threshold is reached. Together with the RMS Compressor, the DS-CP22 also includes 2 very useful Dynamic Processes, An Automatic Gain Controller (AGC) and a Peak limiter.In order to understand the operation of the AGC, please refer to the following graphic:The AGC is an Expansion/Compression process applied with fairly slow Attack and Release times To the INPUT signal, in order to maintain the average amplitude of the OUTPUT signal at a defined level, independently from the averaged amplitude of the input sources.The AGC expands the signal when below the threshold setting, and compresses when above the threshold setting.The process uses RMS levels resulting in a more musical sounding process. The AGC process is useful in maintaining a consistent output level.The Speed and the amount of the Expansion can be defined through the “Exp Time” and“Exp Ratio” parameters. The speed and the amount of the Compression can be defined throughthe “Cmp Time” and “Cmp Ratio” parameters.When the Signal coming out from the AGC process (Output), applied to the AGC input, is above the “Exp Thr” and below the “Thr Hold”, it is expanded up to the max expansion coefficient defined by the Exp Ratio.When the Signal coming out from the AGC process (Output), applied to the AGC input, is above the “Cmp Thr”, it is compressed up to the minimum compression coefficient defined by the“Cmp Ratio”.When the AGC output is comprised within the “Thr Hold” and the “Cmp Thr” Thresholds, no further expansion or compression actions will be taken and the expansion/compression coefficient, will be maintained with its current value.If the averaged AGC output level is “entering” the signal “hold” area coming from theexpansion area, then the Coefficient computed by the AGC for multiplying the input level in order to get the proper output signal, will be higher than one (if the “Exp Ratio” will be set at 1:2), and the coefficient will be lower than one (if the “Cm Ratio” will be set between 2:1 and 16:1) if the Averaged AGC output level is “entering” the signal “hold” area coming from the compression area.The last dynamic process available with the DS-CP22, is a Peak Limiter. This is useful when used before an amplifier to limit the signal to avoid over-driving the amplifier input, or to help protect speakers from excessive level.This kind of Limiter is acting on the Signal Peak detection and therefore the limiting is on the output Peak value.In addition to the Dynamic Processes, in the DP-CP22 there is also a Sub Harmonic Synthesizer available.The Sub Harmonic Synthesizer generates sub Harmonics based on the Harmonic content of the original signal.The amplitude distribution of the generated Sub Harmonics follows the shape of a bandpass filter set on the low part of the band.The peak of this “band pass” filter, is centered on 2 possible frequencies, 60Hz and 90Hz. Setting the filter peak at 60Hz (24-36Hz), the Harmonics added to the original sound will bring a “deep” and very low extra body to the original sound.Setting the filter peak at 90Hz (36-56Hz), the Harmonics added to the original sound will bring a “lighter and more booming” extra body to the original sound.Finally, the DS-CP22 includes 7 bands of equalization:A 1st or 2nd Order Highpass, a 1st or 2nd Order Lowpass, and 5 bands of 1st or 2nd OrderPeaking/Shelving filters.The DS-CP22 has a bypass control which bypasses the entire digital process.Input and Output LevelThe Input and Output levels of the DS-CP22 can be adjusted by Analog Potentiometers.The potentiometers operate in the analog domain before the A/D converter (Input Level) and after The D/A converter (Output Level). There is not an absolute and fixed relationship between the Input and Output Levels and the levels in front of the A/D and after the D/A converters.The figures A and B are show in detail the possible positions of the potentiometers controlling the Analog Input and Output Level.Referring then to the above precise divisions of the available range between the MIN and MAX Position of the potentiometers, the Max Analog Input/Output levels can be understood, so the proper setting for the best use of the RMS Compressor can be found.Figure AFigure B0.5123456789MIN MAX OUTPUT LEVEL1.52.53.54.55.56.57.58.59.50.5123456789MINMAX INPUT LEVEL1.52.53.54.55.56.57.58.59.5Getting Startedexample).From this initial condition, and if an RMS Compressor or a Peak Limiter (or both) are set to be Active, their compression/limiting activity can be seen on the “Compressor Activity” and “Limiter Activity” windows. This is accessible from the Input Level page by rotating the NAVIGATIONInput signal level, and compression depth, refer to the tables.Encoders and ENTER, QUIT buttonsThe DS-CP22 is equipped with 2 Relative Encoders, “PARAMETERS” and “NAVIGATION”. These Encoders are used to navigate the user interface and edit sections of the processor. They allow the User to navigate within the screen for the selection of sub-menus, pages and parameters, and to select the values to be assigned during the editing operations.The “ENTER” and “QUIT” buttons allow the user to confirm or NOT confirm the operations performed by the encoders.Particularly, the “ENTER” button is used to enter the editing pages from the initial Input Level and Compressor/Limiter Activity screens.The “QUIT” button is used to get back from any editing page to those screens.From any one of the Initial windows, the editing menus and pages can be accessed by pressing the “ENTER” button.Once leaving the Input Level and Compressor/Limiter Activity windows, the screen will show on the top row, the currently running preset and name, and on the lower row, the sub-menu for theDS-CP22 functions/parameters access and editing.The available Sub-menus are:˜Load Preset: Loading one of the 32 available presets (16 factory and 16 users)˜Save Preset: Store up to 16 user presets˜Utility Function: Communication Interface setting (USB or MIDI)˜Edit Parameters: Access to the parameters’ editing of all the DS-CP22 processesLoad Preset - this page allows the Loading of a preset program from one of the 16 factory presets (1-16) or from one of the 16 user presets:Preset 16: DeepCmpLoad PresetBy pressing ENTER and rotating the “NAVIGATION” encoder, it is possible to scroll through all current available user presets.Load Preset<Preset:21 AGC_Fat>If the Preset 21 is chosen (AGC_Fat), then pressing the “ENTER” button, the current temporary window will appear,Wait : Loading . . . . . .<Preset:21 AGC_Fat>And the AGC_Fat preset number 21 will be loaded and the sub-menu page will go back to the previous level, updated:Preset 21: AGC_FatLoad PresetSave Preset: this page allows you to store a new preset, up to 16, in the DS-CP22’s memory from location 17 up to location 32, skipping the locations 1 to 16 that are reserved to the Factory presets:Preset21: AGC_FatSave PresetBy pressing the ENTER button and rotating the “PARAMETERS” encoder, it is possible to scroll through the previously saved presets and the available empty locations (identified by “Empty”).If no user presets are stored, the “Save a Program” screen will show empty memory locations for All 17-32 presets as shown in the example below for location 30:Save Preset<Preset:30 Empty >When storing an edited configuration for the DS-CP22, select the location for a preset from the 16 available by using the “PARAMETER” encoder.Edit Name Preset” page.) by using the “PARAMETER”The current position of the cursor is shown by a “blinking underscore”.Utility Functionused for controlling the DS-CP22:original menu.Note: The “QUIT” button, once pressed as many times as necessary, will return to the top LCDLevel, which is the one displaying the Input Level or the Compressor/Limiter Activity.Edit Parameters - in this sub-menu, all the parameters related to the signal processes of theDS-CP22 are available for editing.Pressing the “ENTER” button, the processes can be accessed for editing.With the “NAVIGATION” Encoder, all the processes can be scrolled through and from theIn the Editing Parameters Sub-menu, the available processes are:Routing: Assigns the processor to Channel A, B or A+BInput Gain: Digital control of the Input levelNoise GateA.G.C.Filter 1 – Filter 7: Eq.

Meaning that the signal amplitude can be multiplied for a coefficient not higher than 1.the original one.AGC Cmp Ratio pageIf the Compression Ratio is set to 2 or more, the signal can be expanded up to a min amplitude that is depending from the ratio and can reach 1/16th of the original signal amplitude.Filters 1-7 - the DS-CP22 provides 7 bands Eq. for the adjustment of the Input Signal.The first filter of the Eq. can be selected to be 1st or 2nd Order High-pass or a 1st or 2nd Order Low Shelving. The seventh filter can be 1st or 2nd Order Low-pass or a 1st or 2nd Order High Shelving and the filters from the 2nd to the sixth are Peaking filters.Filter 1 - filter 1 is a filter selectable between a 1st and 2nd Order Butterworth High Pass or a 1st and 2nd Order Low Shelving, or the filter can just be bypassed.The parameters selectable using the NAVIGATION encoder are the following:Type - here the filter type can be selected or just bypassed.Frequency - with the PARAMETER encoder, the frequency of the filter can be set, ranging from20Hz to 20kHz in steps of 1/12Oct.Amplitude - if a Low Shelving filter is selected, you can set the filter’s gain here, ranging from-6dBu up to +6dBu.Filter 2-6 - filter 2-6 are Peaking filters.The parameters selectable using the NAVIGATION encoder are the following:Q-Type - here the filter’s Q can be set ranging from 0.05 up to 2.00 by steps of 0.05.Frequency - with the VARIATION encoder the cutting frequency of the filter can be set ranging from 20Hz to 20kHz by steps of 1/12Oct.Amplitude - here, the filter’s gain can be set, ranging from -6dBu up to +6dBu.Filter 7 - filter 7 is a filter selectable between a 1st and 2nd Order Butterworth Low Pass or a 1st and 2nd Order High Shelving, or the filter can just be bypassed.The parameters selectable using the NAVIGATION encoder are the following:Type - here the filter type can be selected or just bypassed.Frequency - with the PARAMETER encoder the cutting frequency of the filter can be set ranging from 20Hz to 20kHz by steps of 1/12Oct.Amplitude - if a High Shelving filter is selected, here you can set the filter’s gain, ranging from-6dBu up to +6dBu.Sub Harmonic - the Sub Harmonic Synthesizer is a particular process, already introduced in the first part of the manual, that isn’t actually related to the RMS compression one.The Sub Harmonic Synthesizer is intended to be an “extra” process available to the user, where the RMS Compressor is chosen for processing a source addressed to a “background” use, as in clubs. It is possible to have synthesized bass in order to extend the band. Also when themusical program is poor of harmonics in the low frequencies, it can help in improving the quality of the background music and to gain a "heavier" or more vibrant sound.The Sub Harmonic Synthesizer is a process synthesizing the first lower harmonic of the frequencies ranging from 40Hz to 500Hz, detected in the original signal.This means that there in the original signal, are detected frequencies from 40Hz to 500Hz, sub harmonics from 20Hz to 250Hz are generated.Figure FAs can be seen in the Figure F, however, the synthesized sub harmonics are not generated in the Low harmonics’ band with the same amplitude, but with a Peak on 65Hz or on 90Hz and then with decreasing amplitude going up from 65Hz/90Hz to 250Hz and down to 20Hz.This is due to the fact, that to extend the same amplitude to the all sub harmonics generated, would bring a “booming” and “dark” result, where having a Peak on the 65Hz(24-36) or 90Hz(36-56), will leave the max intensity of the synthesized sub harmonics, in correspondence of the original fundamentals, ranging around 130Hz and 180Hz, where typically is the octave used byinstruments such as the Bass or Kick Drum, creating a bigger presence and giving the music that much sought after “punch”.Percentadded to the original Signal.FreqPeak is centered on 65Hz and the max amplitude is +18.6dBu. When 36-56 is selected,the Peak is centered on 90Hz and the Max amplitude is 15.7dBu.DriveDetector.This means the Drive the instead the level “seen” by the RMS level detector.Using the drive, it is possible to get a higher level of compression without changing the input level. In this way, the Drive can extend the compression range 6dB more, or reduce it by 12dB.RMS Compressor - the RMS compressor parameters can be controlled by entering the editing screens and scrolling the parameters with the NAVIGATION encoder and setting them with the PARAMETER encoder:Threshold0.1dBu.RatioH/S KneeSteps of 1%Make Up- within this page, it isthe RMS compressor toPEAK Limiter - the Peak Limiter parameters can be controlled by entering the editing screens and scrolling the parameters with the NAVIGATION encoder and setting them with the PARAMETER encoder.Threshold0.1dBuReleaseand 0.2 from 3s to 5s.AttackMuteUsing the DS-CP22 Software.l Load the Software “SetupDS-CP22V1.0.0” either with the included CD or via the Galaxy Website. l Double click on “Setup”, choose “Run” the software will load.l Go to programs and double click on DS-CP22V1.0.0l Connect the SDS-CP22 with the USB cable to your computer.l Turn on the DS-CP22, the driver software will load automatically.l When the driver has ﬁnished loading, click once on “connect”.If you want to continue select “Yes”Choose your connection type.Then Click on Connect.The software will look for active devices and show them in a list.To edit Double click on the desired device in the ID list.The Main Page will load.The device will also be locked out from front panel control at this point.You may choose to “Load Preset from PC”, “Save Preset to PC”, “Store Preset to Device”, “Read Preset from Device”You can name a device by selecting edit device name.From the main page you can choose the section you want to adjust by clicking on the associated block.

The S2 features a host of new creative processing possibilities never before found in an all analogue dynamics package.BIG- Retains bass frequencies and minimizes undesirable ‘pumping’ by rolling off the detection signal at 75, 125 or 250Hz (user switchable). A fully variable level control allows for the desired amount of Big processing and an in/out switch provides the option to remove from the signal path for A/B comparison.BRIGHT- A dynamic high frequency enhancer to keep compressed audio sounding fresh and bright with continuously variable frequency control (500Hz to 20kHz) and amount of dynamic enhancement.DRY- Mixes user defined amount of ‘uncompressed’ signal with the compressed signal to create ‘parallel compression effect’ without the need for external mixing devices.• 2 CHANNEL SOFT-KNEE TUBE COMPRESSOR• FULLY BALANCED INTERNAL SIGNAL PATH• CLASS A DESIGN• ISOLATION TRANSFORMERS IN AND OUT• ‘ALLTUBE’ CIRCUIT DESIGN• VARIABLE ATTACK AND RELEASE WITH OPTIONAL ‘PROGRAMMEDEPENDENT’ AUTO RELEASE OPERATION• DUAL MONO OR STEREO LINK OPERATION• SWITCHABLE ‘PEAK’ OR ‘VU’ METERING TO DISPLAY TRANSIENTS• SWITCHABLE +10dB OR +20dB METER RE-SCALE MODES• 8 SEGMENT GAIN REDUCTION METERING• ‘VARIABLE-BIG’ MODE FOR RETAINING LOW FREQUENCIES• ‘VARIABLE-AIR’ MODE FOR ENHANCING HIGH FREQUENCIES• ‘DRY’ MIX MODE FOR ‘PARALLEL COMPRESSION EFFECT’• BALANCED XLR INPUTS/OUTPUTS3DRAWMER S2 O PERATOR’S M ANUAL4DRAWMER S2 O PERATOR’S MANUALThe S2 is designed for standard 19" rack mounting and occupies 3U of rack space. Fibre or plastic washers may be used to prevent the front panel becoming marked by the mounting bolts. Always connect the mains earth to the unit.Because the S2 contains six valves it will generate more heat than a simple solid state unit. Avoid mounting theunit directly above power amplifiers or power supplies that radiate significant amounts of heat. In addition it is advised that you leave at least 1U of space above to allow heat to dissipate. Alternatively, a fan should be fitted somewhere near to the rear of the unit to circulate cooler air and help expel any excess heat. (see fig. 1)INSTALLATIONfig.2 TYPICAL S2 SETUPfig.1 RACK MOUNT POSITIONING5DRAWMER S2 O PERATOR’S M ANUALThe unit will have been supplied with a power cable suitable for domestic power outlets in your country.For your own safety it is important that you use thiscable. The unit should alwaysbe connected to themains supply earth using this cable, and no other.If for some reason the unit is to be used at a mains input operating voltage which is different to that as supplied, the following procedure must be carried out.1: Disconnect the unit from the mains.2: Remove the two screws holding the voltage selection cover-plate.3: Remove the cover plate and slide the switch fully to its opposite end.4: Rotate the cover plate one half turn (180 degrees)and refit the two screws.5: Replace with a correctly rated fuse for the selected operation voltage in the IEC socket:230V-T500mA and 115V-T1Amp6: Re-connect to mains power source.Never disconnect the earth from the mains supplyAUDIO CONNECTIONSThe inputs and outputs are electronically balanced on conventionally wired XLRs (pin 1 screen, pin 2 hot, pin 3cold and XLR shell is connected to chassis). The operating level is nominally +4dBu. Balanced use is recommended.• Interference:If the S2 is to be used where it maybe exposed to high levels of disturbance such as found close to a TV or radio transmitter, we advise that it is operated in a balanced configuration. The screens of the signal cables should be connected to the chassis connection on the XLR connector as opposed to connecting to pin1. The S2 conforms to the EMC standards.• Ground Loops:If ground loop problems are encountered, never disconnect the mains earth, but instead, try disconnecting the signal screen on one end of each of the cables connecting the outputs of the S2 to the patchbay. If such measures are necessary, balanced operation is recommended.POWER CONNECTIONfig.4 Altering the Voltagefig.3 XLR WIRING6DRAWMER S2 O PERATOR’S M ANUALCONTROL DESCRIPTIONCHAPTER 21 MAIN COMPRESSOR CONTROLSThreshold:+20dB - -26dBDetermines the input level above which gain reduction will be applied.In order to provide as transparent processing as possible Soft knee compression takes place for signals exceeding the threshold level by a few decibels, above which level conventional ‘ratio’ compression is applied.Gain Reduction Meter:Eight Leds at 0,-1,-3,-5,-7,-10,-15,-20dBRatio: 1.4:1 - 10:1Sets the final compression ratio that will be applied once the 'soft-knee' region of the threshold control is exceeded.A ratio of 1:1 provides no compression, whereas approaching 10:1corresponds to more of a limiter.Attack:0.2mS - 100mSControls the speed that the compressor responds to signals that exceed the level set by threshold. For most musical uses, an initial attack setting of between 1 and 20 mS is typical and least obtrusive, with slower settings allowing the start of a percussive or transient signal to pass unaltered, before the compressor reacts. However, bringing the level under control quickly, using a very fast attack time, generally gives more natural results on vocals and mixes.Auto Release:Off - 1 - 2When selected, Auto disables the Release control and continually optimises the release times to suit the dynamics of the material being processed - with 1 having a slightly quicker release than 2 to further suit the varied signals. In general, this setting will produce the least obtrusive level control on signals with widely varying dynamics such as complete mixes.Release:0.05S - 2.0SecondsSets the time taken for the signal to return to normal after the input level has fallen below threshold. For most signals setting the realease at around 0.2 to 0.6 seconds is a good starting point. Be careful with very long release settings, the Compressor might never have enough time for a total recovery between the signal peaks. However, if set too fast, the signal may “pump”, which can be used creatively, but is generally undesirable.2 V-BIGUnlike previous Drawmer compressors the S2 V-Big control is fully variable allowing complete and subtle adjustments to the perceived level of bass, and the control of ‘pumping’ and ducking that occurs.Frequency:75, 125, 250 HzSets the frequency that the ‘V-Big’ control operates at, enabling the engineer to target a specific bass frequency.Level:-10 - +10With the control set in a positive position the side chain's sensitivity to low frequencies is reduced, with the result that less gain reduction is applied to those frequencies, creating the effect that the bass is louder or 'bigger'. It also has the benefit of reducing the ducking and pumping effect that occurs by high frequencies being 'pulled down' in sync with the bass, helping to make mix compression much more affable.If set in a negative position the opposite occurs i.e. with bass frequencies being quieter and pumping increased.At the 0 position the ‘V-Big’ control is effectively off.Active:Off - OnSwitches the ‘Big’ control on and off.3 V-AIRV(ariable)-Air is used to manipulate the high end of an audio signal so that it sounds more intimate, detailed and transparent, but without making it sound harsh or introducing any noticeably unnatural artefacts. Cymbals are more vibrant without becoming splashy, and vocals sound more open but without becoming sibilant.On the S2 the ‘V-Air’ section is not just an everyday side chain E.Q. that most compressor’s would incorporate, replacing any dulling of high frequency detail by simply adding gain, but a fully variable dynamic process that works in conjunction with the compressor, giving more ‘brightness’ as and when it’s required. Being full range the S2 will compress quiet high frequencies whenever the low frequencies are being brought under control, resulting ina dulling of these high levels, and in the worst cases, pumping - it is here where the V-Air controls are at their mosteffective. As shown previously, the ‘Big’ section can also improve things.Frequency:500Hz - 12kHzSets the frequency at which the ‘V-Air’ control operates, enabling the engineer to target a specific frequency.Level:-10 - +10At the 0 position the ‘V-Air’ control is off. In a positive position higher frequencies are enhanced, to add definition, particularly to the human voice and accoustic instruments - a negative position has the opposite effect, and may be used to bring back the balance to a mix whose cymbols are too conspicuous, for example.Active:Off - OnSwitches the ‘V-Air’ control on and off.4 DRYDry works by adding the original signal coming into the unit to the compressed signal that has been processed by the S2, effectively reducing the percieved amount of compression taking place. It is easiest to think of it as being similar to a parallel compressor, but with the advantage of being one simple knob. It provides completely variable control over the whole amount of compression taking place without having to alter numerous settings in order to do so.Level:0 - 10At the 0 setting a fully wet (compressed) signal is passed through to the output. As the control is turned up to 10 the dry signal (no compression) is added, thus lowering the percieved amount of compression. Unlike conventional wet/dry mixes the signal is never completely dry, even at 10 there is still a little compression taking place - use the ‘unit bypass’ (section 7) switch for a completely dry signal.Active:Off - OnSwitches the ‘Dry’ control on and off. When ‘off’ the signal is fully ‘wet’ i.e. compressed.7DRAWMER S2 O PERATOR’S M ANUAL5 GAINGain:-10dB - +20dBDuring compression the signal is attenuated, gain may be required to produce the required output level. The amount of gain required in order to bring the signal level to the same is at input is displayed on the G.R. meter.6 STEREO LINKStereo Link:Off - MasterWhen processing stereo signals, the compression settings of both channels should be the same, otherwise the stereo image will wander if one channel receives more compression than the other. When ‘Stereo Link’ is in the side chain follows both channels and forces the compressor to react to whichever of the channels is at the highest level at any given time, processing both signals according to the settings of Channel 1 (Master). The only exception to this are the ‘Gain’ controls, these remain independant - this is in order to provide a level balance between the two channels.7 METERING AND POWERVU Meters:Two moving coil VU meters monitor the level of the output signal of each channel.Pad:Vu - +10dB - +20dBA three-position switch adjusts the meters to show either normal output level, (and for those working at ‘hot’ outputlevels) VU +10dB or VU +20dB modes. i.e. with the switch at VU +10dB - when the VU meter reads 0dB the actual level is +10dB.Response:Peak VU - VUOn smooth, gentle pieces of music the “VU” (average level) setting would be sufficient, however, on fast dynamic signals the “Peak VU” setting provides more accurate readings.Bypass:Off - OnA fully balanced hard-wire unit bypass connects the input directly to the output, enabling an instant wet/dry comparison.Note: in bypass the VU meters display the levels as though the unit is still compressing. This has been implemented to provide the user with optimum control of the meters.Temperature LedThe S2 is at optimum temperature when the front panel LED indicator is lit, i.e. after the soft start and when the valves have reached optimum temperature - this may take a few seconds.Power:Off - On8DRAWMER S2 O PERATOR’S M ANUAL9DRAWMER S2 O PERATOR’S M ANUALQUICK SETUP PROCEDUREPlease note that the following procedure is only a guide. All audio is different, requiring numerous settings, however,this should give a good staring point:For single channel use, each channel may be considered as being completely independent and set upaccordingly. For use with stereo signals such as complete mixes or submixes, the S2 should be switched to Stereo Link mode and all setting up done using the left hand channel controls.To begin set the compressor controls as above - Threshold fully anti-clockwise, Ratio set to 2:1, the Attack in a mid position (around 20mS) and the Auto Release switch to 1, with Gain at 0dB.V-Big , V-Air and Dry can be bypassed for the time being.Keeping an eye on the Gain Reduction Meters alter the Threshold control for each channel to a level that ‘triggers’ the compressor, and then adjust the the Ratio until the desired compression level is achieved - as a rule,higher ratios provide a higher degree of control but also tend to be more audible in operation when high levels of gain reduction are required - a G.R. level up to -10dB is pensate for the overall drop in output caused by the compression by adjusting the Gain control until 0dB is reached on the Output VU meter (more if in +10dB VU or +20dB modes).Set the Attack knob according to the speed of the audio being processed. It is recommended that the Auto Rel.switch remains on, as it adapts dynamically to the audio, however, if manual release is preferred set the Auto Rel.switch to off, and adjust the Release control. Bear in mind that too short a release time will result in pumping.At this point the Bypass switches can be toggled to listen to the affect that the S2 is having on the audio. Repeat steps 2,3 and 4 to suit.V-Big can now be introduced - set the switch to your target frequency , and rotate the level control until the desired amount of bass is reached.To improve the audio at higher frequencies use the V-Air section, setting the controls in much the same way as V-Big - adjust to suit your taste.The S2 is now basically set up, however, further control is provided via the Dry section. With the switch active,rotating the level control clockwise adds the original, uncompressed signal to the compressed, effectively reducing the percieved amount of compression taking place. Using Dry can bring even the most severely compressed audio under control - again, adjust to suit your own taste. The Gain control may need to be adjusted to bring the output to a suitable level.1)2)3)4)5)6)7)8)9)OPFo use setSe the con hig pro ratIf t co red red coCo qu higAt lon is o attTh occCo exa cau sou to d inc ga us miAt ob thr po an theBe res thr coFin ou On pe enIf r ha effclo10DRAWMER S2 O PERATOR’S M ANUALCHAPTER 3IF A FAULT DEVELOPSFor warranty service please call Drawmer Electronics Ltd. or their nearest authorised service facility, giving full details of the difficulty.A list of all main dealers can be found on the Drawmer webpages.On receipt of this information, service or shipping instructions will be forwarded to you.No equipment should be returned under the warranty without prior consent from Drawmer or their authorised representative.For service claims under the warranty agreement a service Returns Authorisation (RA) number will be issued.Write this RA number in large letters in a prominent position on the shipping box.
