The dB12 offers all the benefits of a premium-quality Direct Box while preserving the sonic integrity and true characteristics of the signal source with its custom dbx mu-metal-shielded audio transformer, high-quality Neutrik ® connectors, and low-noise circuitry. The dB12 includes a pad switch for instrument, line and even speaker level signals. And you can take even more control of your sound by utilizing the polarity invert switch to set the phase rela-tionship between the direct and mic’d sound.The dB12 Features Premium Performance Rugged DesignStackable Chassis with Durable Rubber FootGold-plated Neutrik® XLR Connector Premium Chrome Toggle Switches Hi-Z ¼" Input Jack Parallel ¼" Thru Jack Transformer IsolatedPremium Shielded Custom dbx Transformer•••••••Balanced XLR Lo-Z Output 3-Way 0/20/40 dB Pad Switch Flat/High-Cut Filter Switch Output Polarity Invert Switch Ground Lift SwitchGreen LED Phantom Power Indicator +48V Phantom Powered Operation Low-Noise Active Circuitry••••••••Front PanelRear PanelRear PanelPOWER LEDLights when receiving power from phantom power.PIN 1 (LIFT/GND)By switching to the LIFT position, the internal connection to the output pin 1 is removed, isolating the dB12’s grounding system from the rest of the system.

After expiration of the warranty, a reasonable charge will be made for parts, labor, and pack-ing if you choose to use the factory service facility. In all cases, you are responsible for transpor-tation charges to the factory. dbx will pay return shipping if the unit is still under e the original packing material if it is available. Mark the package with the name of the shipper and with these words in red: DELICATE INSTRUMENT, FRAGILE! Insure the package properly. Ship prepaid, not collect. Do not ship parcel post.Example Setup 1: Guitar signal sent to amp and PA/MixerExample Setup 2: Direct guitar signal and amped signal on two mixer channelsSpecial FunctionsPolarity InvertThe polarity function is used in situations where the direct box is used as a splitter, and two “sort-of parallel” signals are fed to two mixer channels to be perhaps panned left and right for a nice stereo sound. Flipping the Polarity Invert function will change the phase relationship between the two signals and will typically result in significantly different-sounding results.A typical example would be to plug a guitar into the input of the direct box, then feed the signal directly back out the Thru jack and into the guitar amp. Then the guitar amp would either be mic’d and sent to one mixer input channel, or a direct output on the guitar amp would be sent to the mixer channel. The output of the direct box would be fed into a second mixer input chan-nel, and the Polarity Invert switch position would then be selected based on preference on how it sounds. In the situation where the amp is mic’d, the position of the mic away from the guitar amp speaker also affects the exact phase relationship between the two guitar signals as well.FilterWhen a guitar amp is mic’d, not only does the guitar amp speaker not reproduce high frequencies, but the mic typically does not reproduce high frequencies well either at these loud levels. Thus, a mic’d guitar amp has significantly subdued “high-end”. Since the 0 / 20 / 40 dB pad feature allows input connection directly from the speaker output of a guitar amp or power amp* when switched to the 40 dB pad position, the Hi-Cut filter is used in conjunction with the 40 dB pad on an amplifier output signal to roughly duplicate the sound of a mic’d speaker. Otherwise the signal would have much more high frequency content and would sound “tinny” in comparison.NOTE: The Filter switch only works when the Pad switch is set to 40 dB.* See the maximum input level specification.If you want to dispose this product,do not mix it with general household waste.There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment,recovery and recycling.Private household in the 25member states of the EU,in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one).For Countries not mentioned above, please contact your local authorities for a correct method of disposal.By doing so you will ensure that your disposed product undergoes the necessary treatment,recovery and recycling and thus prevent potential negative effects on the environment and human health.WarrantyThis warranty is valid only for the original purchaser and only in the United States.1.

In no event shall dbx or its dealers be liable for special or consequen-tial damages or from any delay in the performance of this warranty due to causes beyond their control.What Does a Direct Box Do?First, a direct box converts the audio signal originating from an unbalanced device (like a guitar) to a balanced audio signal for transmission over a longer distance than is recommended for an unbalanced signal to travel. As audio industry people know, the advantage of a balanced signal is realized at the receiving end (audio input) of the balanced cable, typically in the form of a mic pre-amp input on a mixing console. The mic pre input circuitry consists of a “differential amplifier” whose job it is to “accept” the audio portion of input signal and “reject” the noise portion of the signal. The noise portion happens to be roughly equivalent on (or “common to”) both the “+” and “-” balanced conductors in the mic cable, since external electromagnetic fields are induced onto both conductors in a roughly similar fashion. Since the conductors are always in a “twisted pair” configuration, they “see” the same noise field. Thus, this is known as “com-mon-mode noise”. Another type of common-mode noise somewhat evenly-induced onto bothconductors is due to the inherent physics of connecting two pieces of equipment together and the resulting flow of electrons due to noise voltages present at each piece of equipment. The ability of a balanced input to reject common-mode noise is measured in dB and called its “common-mode rejection ratio”, or CMRR.The second function of a direct box is to convert from a high-impedance output – on an instru-ment such as electric guitar with passive pickups, for instance – to a low-impedance output. A cable driven by a high-impedance output is more susceptible to signal loss and noise pickup than a cable driven by a low-impedance output. Thus, using a direct box again improves, for a dif-ferent reason, the ability to run longer distances due to the impedance conversion from high to low-impedance.Third, at the heart of the direct box is an isolation transformer that allows complete “galvanic” isolation, if desired, between the equipment plugged into either end. This eliminates the hum and buzz present in the system due to ground loops.SpecificationsCircuit Type:Input :Number of Connectors:Connection:Type:Attenuation Pad:Filter:Max Input Level (0 dB Pad):(20 dB Pad):(40 dB Pad):Input Impedance (0dB):(-20dB):(-40dB):Outputs :Number of Connectors:Main Output:THRU Output:Main Output Impedance:Main Output CMRR (60 Hz):(1 kHz):(10 kHz)Output Polarity:Performance :Bandwidth:Frequency Response:Phase Deviation (Input ð Output):Insertion Loss:Harmonic Distortion (THD+N):Noise Floor:Dynamic Range:Power Supply :Voltage:Current:Ground:Physical :Size (L x W x H):Weight:Construction:Finish:Active11/4” TS (Tip Hot, Sleeve Ground)Unbalanced, RF Filtered Switchable: 0, 20, 40 dBSwitchable: Low Pass @ 6 kHz (40 dB pad position only)+10 dBu typical @ 1 kHz with <1% THD +30 dBu typical @ 1 kHz with <1% THD +33 dBu 1 M Ω65 k Ω70 k Ω2Male XLR, Balanced, Pin 2 hot1/4” Unbalanced TS (Tip Hot, Sleeve Ground)600 Ω typical, balanced 106 dB typical @ 60 Hz 123 dB typical @ 1 kHz 108 dB typical @ 10 kHz Switchable: Normal / Invert20 Hz to 20 kHz +0/-2 dB typical with 600 Ω load20 Hz to 20 kHz +0/-1 dB typical with 2 k Ω or higher load16 Hz to 30 kHz, -3 dB, with 600 Ω Load10 Hz to 70 kHz, -3 dB, with 2 k Ω or higher load+40 deg @ 20 Hz, -20 deg @ 20 kHz into 2 k Ω load 1 dB typical 0.03% typical @ 50 Hz, 0 dBu0.003% typical @ 1 kHz, 0 dBu 0.005%typical @ 10 kHz, 0 dBu-112 dBu, 22 Hz to 22 kHz, unweighted 122 dB, 22 Hz to 22 kHz, unweighted+48 V Phantom Power< 8 mA Switchable: Ground / Lift 5.82” X 5.44” X 2.20”1.5 lbs.
