Eventide H910 Harmonizer产品介绍说明书
Original Marketing Material circa 1976IntroductionThe H910 Harmonizer was pro audio’s first digital audio effects unit. The ability to manipulate time, pitch and feedback with just a few knobs and switches made it easy to alter audio in ways that otherwise required at least a couple of tape machines and, often, rearranging furniture. Suddenly anyone could be Les Paul (recording engineer not guitar player).The H910’s electronics were primitive and the processing almost entirely analog. The digital bits of the design did “as little as necessary.” Only delay was digital. Everything else - filtering, feedback, mixing, pitch modulation, etc. - was analog. And it sounded it.The H910 was also just a tiny bit unstable. And it showed. In a time long before CDs, MIDI, or any standards for sample rate or bits, Light Emitting Diodes (LEDs) had just become “the latest, greatest thing” and the H910’s iconic, flickering display was the first ‘digital readout’ to appear in many studios. And that flickering readout belied a secret – the H910 was inherently ‘jittery’. The H910’s master clock wasn’t crystal-based but, instead, it was a tuned LC (inductor/capacitor) oscillator. The result is that the system was not locked to a specific frequency and the entire system’s clocking would drift slightly, slowly and unpredictably. In fact, all of the oscillators in the H910 are of the ‘free-running’ sort and this randomness adds to the sound (and the fun).The H910 was groundbreaking when introduced and now the circuitry, the functionality and the ‘sonic behavior’ of the original has been modeled in software and is available in your DAW for the first time. Note that while presets are a good starting point, you’ll get the most out of the H910 if you push buttons and turn knobs - just as you would when searching for a sound using the hardware. That was always, and is now, once again, the fun of it.Genesis of the H910Prior to 1970 there were no digital audio products of any kind, in any studio, anywhere. The first digital audio product to appear was a one-trick-pony, the DDL (Digital Delay Line). First introduced in 1971, DDLs from Eventide and Lexicon were as simple as simple can be - audio goes in now and comes out a bit later. Eventide’s 1745, was a big, costly box full of shift registers with a front panel dominated by big ‘wafer’ switches. Designed in 1972, during the very early days of ICs (Integrated Circuits), the only chips with enough memory (storage) to be dangerous/useful were 1K bit shift registers. RAMs were expensive and teeny. Each 1kbit shift register could delay audio by ~2 mS, so that, by filling a box with ‘only’ 100 of these chips an amazing 200 mS of delay became possible!Studios bought Eventide’s 1745 to use as a pre-delay for a plate reverb or for ADT (automatic double tracking). Eventide’s audio design sounded ‘good enough’ to satisfy even the most critical ears (some early digital audio products sounded awful) thanks, in large part, to Eventide’s custom designed ADC (analog to digital converter). And so, fueled by the sales of a handful of 1745s, Eventide took the next step and developed the successor to the 1745, the 1745M. The 1745M was also a simple DDL but it was modular DDL and used RAM instead of shift registers making fine control of delay possible for the first time. And it had 7 segment numerical LED readouts! The introduction of a “pitch change” module for the 1745M set the stage for the development of the H910. By 1974, most of the pieces needed to design a “Harmonizer” were in place. The Rack Mount H910The H910 was conceived as a box that a vocalist might use to create real-time harmonies and reverb. In fact, the prototype sported a keyboard for selecting musical pitch intervals. (An optional keyboard controller was offered in production.) Much of the H910’s analog circuitry is borrowed from the DDLs. RAM storage was used for delay. By giving the user real time, interactive control of pitch, delay and feedback, the H910 ushered in the digital effects era and became a key instrument allowing engineers and producers to shape sounds in new ways. In a pre-software world, the H910 achieved its groundbreaking effects through the judicious application of analog circuitry, custom converters, and digital logic gates. The H910 Plug-inThis plug-in models the hardware to the best of our ability. It even emulates the randomness of the hardware (not that you can copy ‘random’ with any degree of exactitude). The controls have the same range and characteristics as the front panel controls of the hardware. The pitch change splicing method is the same as the hardware’s – the glitch is back!We’ve done exhaustive listening tests and compared it to the best relics that we could find. This plug-in models the quirkiness of one vintage H910. In fact, we’ve tweaked the plug-in to sound as close to the ‘golden’ relic as possible. (If this plugin sounds different from your H910, you may want to get your hardware adjusted.)H910 ControlsThe H910 user interface consists of two parts. The top half of the interface is the front panel of the original H910 2U rack mount unit. All controls function in the same way as the original. The bottom half of the interface enables features originally available through external connections or options. Front Panel Controls:LINE button: This control switches the Harmonizer in and out of an audio circuit. When the switch is inthe OUT position, the unit is completely bypassed but the algorithm is still running in the background. This allows you to store audio in the feedback patch and modify its contents using the pitch controls, then to hear these differences when you revert to LINE IN.INPUT LEVEL knob and LIMIT indicator: This control varies the level of the audio input to the Harmonizer. Users of the original hardware would always be tweaking this pot! The plug-in models the hardware analog input audio circuitry of the H910 and, let’s just say that, the level of the input audio will change the effect of the other parameters, especially when making use of the feedback control. We recommend that you play with this parameter and listen.Input Level should be adjusted to take advantage of the maximum dynamic range of the digital and analog circuitry by setting the control as far clockwise as possible before excessive distortion becomes apparent on the output signal.The LIMIT indicator is used as an aid in setting the INPUT LEVEL control. It is adjusted to give a brief flash each time the maximum dynamic range is even momentarily exceeded.NOTE:Because the LIMIT indicator is peak responding, and because of the characteristics of the internal signal processing circuitry, it is desirable for the indicator to flash occasionally during normal operation.The amount of flashing is strongly dependent upon the nature of the input signal. As an aid to the operator, a general guide is provided:SIGNAL SOURCE LIMIT INDICATOR DUTY CYCLE Integrated program (radio) once per two secondsIntegrated program (live) once per secondVoice (talking) once per two secondsPiano 2-3 per secondGuitar, acoustic 2 per secondGuitar, fuzz 1 per secondSynthesizer infrequentOrgan infrequentDrums once per beatRemember, the above is a general guideline! The ear is the best measuring instrument around, and the best setting is one at which the output level is maximum and distortion is not yet evident. Additionally right clicking on the INPUT knob will turn it to - dB, muting the input. Right clicking again will toggle the INPUT knob back to its previous value.DELAY ONLY button and LED:This switch determines the mode of operation of the Harmonizer’s main output. When it is depressed, the pitch change function is defeated, and the Harmonizer acts strictly as a digital delay line. In this mode, the LED next to the DELAY ONLY button becomes illuminated and the legends beneath the ADD’L DELAY switch group become relevant.When the DELAY ONLY switch is in the out position, the LED adjacent to the PITCH CONTROL SELECT switch group becomes illuminated, and only the two right hand buttons in the ADD’L DELAY group are active. In this case, the legends above the switches are relevant.ADD'L DELAY switch group:This switch group controls the delay of the main output. In the DELAY ONLY mode, the delay is the sum of the delays of the individual switches depressed, as read out on the bottom of the switch group. Maximum delay is 7.5+15+30+60 milliseconds (112.5 mS), and any intermediate setting can be achieved in 7.5ms steps by combining buttons.In the PITCH CHANGE mode, the additional delay is the sum of the delays of the two right hand switches depressed. Maximum additional delay is 60 mS (30+30). Note that in the PITCH CHANGE mode, pitch change is achieved by a delay that is continuously varying over an approximate 30 mS range, and so a precise delay is not achievable. So even without both ADD'L DELAY buttons pressed there will still be an audible delay when in PITCH CHANGE mode.FEEDBACK knob: The FEEDBACK control is used to add reverb in controlled amounts to the delayed output of the Harmonizer. The control attenuates the signal coming from the main output and reapplies it to the input where it is mixed with the incoming signal. The reverb period is controlled by the DELAY setting and the decay time is varied by adjustment of the FEEDBACK control. Clockwise rotation of the control increases decay time, until the feedback gain exceeds unity, at which time the system will begin to oscillate. The control is also operative in the PITCH CHANGE mode, and may be used to create numerous special effects.PITCH RATIO readout:An LED readout gives the numerical pitch ratio of the Harmonizer. As this is a true digital readout, it is not subject to miscalibration and may be used as a precise reference.For musical applications, our optional keyboard will allow setting to precise intervals automatically. These same intervals can be set using the readout, and referring to the chart showing PITCH RATIO READOUTS FOR VARIOUS MUSICAL RELATIONSHIPS.PITCH RATIO READOUTSFOR VARIOUS MUSICAL RELATIONSHIPSThe figures in this table are accurate to four decimal places.For use with the Model H910 Harmonizer, round off the figure two decimal places.-3/4 -1/2 -1/4 NOTE RELATIONSHIP NOTE +1/4 +1/2 +3/40.9576 0.9715 0.9857 1.0000UNISON 1.0000 1.0145 1.0293 1.04430.9039 0.9170 0.9303 0.9439 -1+1 1.0595 1.0749 1.0905 1.10640.8531 0.8655 0.8781 0.8909 -2+2 1.1225 1.1388 1.1554 1.17220.8052 0.8170 0.8288 0.8409 -3+3 1.1892 1.2065 1.2241 1.24190.7601 0.7711 0.7823 0.7937 -4+4 1.2599 1.2782 1.2968 1.31570.7174 0.7278 0.7384 0.7492 -5+5 1.3348 1.3543 1.3740 1.39390.6771 0.6870 0.6970 0.7071 -6+6 1.4142 1.4348 1.4557 1.47680.6391 0.6484 0.6579 0.6674 -7+7 1.4983 1.5201 1.5422 1.56460.6033 0.6120 0.6209 0.6300 -8+8 1.5874 1.6105 1.6339 1.65770.5694 0.5777 0.5861 0.5946 -9+9 1.6818 17063 1.7311 1.75630.5374 0.5453 0.5532 0.5621 -10+10 1.7818 1.8077 1.8340 1.86070.5073 0.5147 0.5221 0.5297 -11+11 1.8877 1.9152 1.9431 1.97130.5000OCTAVE 2.0000OUTPUT 2 delay buttons: This switch group controls the delay of the second output. It is operative regardless of the setting of the DELAY ONLY switch. Delay 2 is fed from the sum of the input to the H910 and the main feedback path. Delay 2’s input is connected before the input to the pitch shifterso pitch change at Delay 2's output will only be heard when feedback is turned up. The total delay of Delay 2 is the sum of the buttons depressed.MANUAL knob: The MANUAL control is operative in the PITCH CHANGE mode only and when the PITCH CONTROL SELECT is set to MAN mode. It is used to change the pitch ratio between the input and the output. When centered, the ratio is unity. When fully clockwise, the ratio is 2, and the output pitch is increased by one octave. When fully counter-clockwise, the ratio is .5, and the output pitch is decreased by one octave. Intermediate settings produce fractional octave ratios, and the control is “band-spread” around unity to make small ratio adjustments easier.PITCH CONTROL SELECT switch group and LED indicator: When the PITCH CONTROL mode is activated, the LED INDICATOR immediately to the left of the PITCH CONTROL SELECT switch group becomes illuminated, and the four switches assume control of the pitch change function.•Manual: This switch selects the MANUAL control, as described above.•A-F: Depressing the Anti-Feedback switch selects the ANTI-FEEDBACK control, as described below.•KYBD: Allows controlling the H910 Pitch Ratio using by the HK 941 ‘piano style’ keyboard and/or MIDI Note On/Off messages between C3 and C5. The HK 941 Keyboard is available in the bottom half of the H910 plug-in.•ENV: ENVELOPE FOLLOWER controls the pitch ratio. When ENV is active, no input signal will result in a PITCH RATIO of 1.0 and a full scale input signal will set the PITCH RATIO according to the position of the MANUAL control. In other words, the setting of the manual control determines the pitch range.ANTI-FEEDBACK knob: This control is operative in the PITCH CHANGE mode only, when the A-F button in the PITCH CONTROL SELECT group is depressed. Increasing clockwise rotation of the ANTI-FEEDBACK control progressively adds a small up and down frequency shift to the output signal, which serves to decrease the effect of room resonance peaks on the signal which ultimately re-arrives at the microphone. Because the effect becomes more audible as the control is advanced, the optimum setting is a compromise between adequate feedback reduction and audience and/or performer disturbance. At extreme settings this control will create a highly modulated FM like effect which can be used as a special effect.POWER button and LED indicator: The power button functions as a bypass switch. When the POWER button is depressed the H910 plug-in is active. Otherwise the H910 plug-in is inactive and if the DSP can be unloaded it will be. Additional ControlsMIXER SectionMIX slider: This slider controls the relative level of the DRY signal and the WET signal comprised of the mixed MAIN OUTPUT and OUTPUT 2 based on their relative slider positions. Right clicking on the MIX slider will activate a solo mode which will play the WET signal only. Right clicking again will toggle back to the initial MIX position.MAIN slider: This slider controls the contribution of the MAIN output to the WET channel, whether it's set to PITCH CHANGE mode or DELAY ONLY mode. Right clicking on the MAIN slider will enter a solo mode which plays only the MAIN output at full scale. Right clicking again will toggle back to the original MIXER settings.OUT 2 slider: This slider controls the contribution of the delayed OUTPUT 2 signal to the WET channel. Right clicking the OUT 2 slider will enter a solo mode which plays only the OUTPUT 2 signal at full scale. Right clicking again will toggle back to the original MIXER settings.ENVELOPE FOLLOWER SectionATTACK knob: The ATTACK knob sets the ENVELOPE FOLLOWER's attack time from 1 to 100 mS.RELEASE knob: The RELEASE knob sets the ENVELOPE FOLLOWER's release time from 10 mS to 1 S.SENSITIVITY knob: The SENSITIVITY knob sets the gain of the ENVELOPE FOLLOWER allowing you to control the pitch change relative to the dynamics of the input signal. As the SENSITIVITY knob is turned clockwise the ENVELOPE FOLLOWER will have more gain allowing quieter signals to have a greater control over the pitch change.EVENTIDE HK941 Keyboard SectionKEYBOARD: The KEYBOARD is a two octave piano style keyboard. The low C represents a PITCH RATIO of 0.5 representing a PITCH CHANGE of 1 octave down. The middle C represents a PITCH RATIO of 1.0 representing a PITCH CHANGE of unison. The high C represents a PITCH RATIO of 2.0 representing a PITCH CHANGE of 1 octave up. Each other note represents a PITCH CHANGE equal to that number of semitones away from the middle C. Therefore playing a note will allow you to transpose the input audio by the number of semitones selected by the note.GLIDE slider: The GLIDE slider allows you to set the speed at which the PITCH CHANGE amount will change when a new key is depressed. This will allow you to add portamento to your transposition.HOLD button and LED indicator: If the HOLD button is depressed clicking on a key will lock the PITCH CHANGE to that number of semitones until another key is pressed. Otherwise the PITCH CHANGE will reset to unison when you cease pressing the key.Model H910 Harmonizer ® Part #141252 Rev BEventide Inc.

德生收音机图纸
1.德生R-202T型两波段收音机电路图2. “德生”二次变频收音机R9701电路分析接收机二次变频技木早先主要用于军事通信领域，以后逐渐用于民用通讯设备，如对讲机、移动电话、收信机等。
国内将此技术移植于收音机中的德生公司第一家。
第一代“短波王”R9700的推出，曾畅销大江南北，此后，又先后推出R970l、R9702等功能更优异，使用更方便的机型。
二次变频技术与传统的超外差式收音机的电路结构比较，见图1所示。
可以看出，二次变频的应用，使收音机的接收灵敏度和选择性等指标大大提高。
下面将承前启后的R9701机作一典型介绍：图2是德生R970l AM／FM前级电路图，图3为其功放电路与操作功能显示电路。
K1为电源开关。
图2中的Q6、Q7等元件组成双稳态电子波段切换开关。
由于开机瞬间，C10上的电压不能突变，Q7截止，电源电压E+通过R13、R9使Q6导通，其集电极上的低电平使Q4导通，Icl 14脚输入高电平，于是ICl工作在FM状态。
与此同时，Q6集电极外接的FM LED点亮。
拉杆天线ANT接收到的高频信号经CO、F3、c5耦合至Icl①脚。
Icl是一片低电压AM／FM收音机专用集成电路，内含AM／FM本振，混频及检波电路，内部结构如图4所示，引脚功能及实测数据如表1所示。
Icl①脚输入的FM信号经内部高频放大从15脚输出，再由PVC2、C8、L4选频后与PVC2同步调谐的本振信号(PvC3、L5、C24、ICl③脚内部元件组成)一起送入混频器。
混频后从③脚输出的10．7MHz中频信号再经FM选频并送入ICl⑧脚，经内部中频放大，FM鉴频后通过电子开关选通，从11脚输出鉴频后的音频信号。
TuN LED为电台强场指示灯(见图3)。
按动电子波段开关AM时，即相当于给Q6基极一个人为的低电平．Q6截止，FM LED熄灭。
同时Q4也因高电平而截止，ICl工作在调幅波段。
Q6集电极的高电平又使Q7由截止转为导通，AMLED点亮。

SONY钟控收音机的常用功能键和使用说明
SONY钟控收音机的常用功能键和使用说明大沙头RADIO1．什么是NAP功能，NAP功能就是在按下此键后，机器会以此时间为计时起点，并按照您按下NAP 功能上所显示的数字为时间间隔闹钟。
比如，当前时间为12。
01分，您按下NAP功能键为10，刚等到12。
11分时，机器就会闹铃了。
一般这个NAP功能是可以多种选择的的，如10。
20。
30。
60。
OFF，机器可循环显示。
其实用性，比如你在中午想睡60分钟，就不需要再设开机时间了，只需按下NAP键，选择60分钟，机器就会在60分钟后自动打开将你闹醒。
2．什么是SNOOZESNOOZE功能，SNOOZE功能是一个非常实用的设计，比如你设早上7。
00开机，但是到了7。
00开机后，你还想再睡一小会儿，你就可以按下此键，机器将被关闭，如果是数调收音机，会显示一个数字，机器过了这个时间数后，机器就会打开。
如果是手调式的钟控机，按下此键，机器一样会被关闭，机器过8分钟后就会自动打开，这点设计有点类似于诺基亚手机的闹钟功能。
3．什么是SLEEP OFF功能SLEEP OFF睡眠关机功能，当你按下此键后，机器就会按你所设定的时间自动关机，即使你睡着了，机器也会自动关机。
睡眠定时关机的时间设定方法如下：一般有二种方式，一般的数调型SLEEP键下都预存有10。
20。
30。
60。
120，SLEEP OFF这些常用的睡眠时间，你可以按下SLEEP 键依次选择。
对于一些手调的机型，睡眠关机时间是可以从1分----1小时59分钟任意选择的。
具体操作方法如下：同时按下SLEEP，CLOCK与H，或M三个键设定睡眠关机时间。
4．CLOCK键。
CLOCK键就是时钟键，对于SONY钟控机来说，一般的操作方法是按下此键后，显示时间就会依次显示日历，小时，和分钟。
配合“+，—”键即可设置好主时间。
一般的操作方法有两种，第一种是按下CLOCK键后，利用“+，—”和CLOCK键依次设好小时和分钟，每二种是用CLOCK键与“+，—”同时按下，这时系统时钟会飞速计数，等到计数到你要的时间时松开CLOCK键就，这时就可以获得你想要的系统当前时间了。
