Apex ADP2 Passive Direct Box
This sturdy and dependable unit allows you to connect the output of an electronic musical instrument or other audio source to the balanced input on a mixer. Alternatively, the ADP2 allows connection of an audio source to an instrument amplifier while simultaneously patching it to a channel on a mixer. It even gives you the ability to connect the speaker output of an instrument amplifier directly to the input of a mixer – especially desirable in the case of a tube guitar amp (speakers must also be connected, see below).
Electric Guitar/Bass Pick-Up Signals - The high impedance signal from a guitar or bass pickup is translated by the ADP2 into a low impedance balanced signal required by mixing consoles. »»Suggested attenuation setting: 0dB««
Keyboards/Line Level Signals - The ADP2 automatically balances and matches the line level outputs of modern electronic keyboards. If you are using a multiple keyboard setup with your keyboards plugged into an instrument amplifier, simply connect the line output of the instrument amplifier to the ADP2 with an unbalanced patch cable, then use a balanced patch cable to go to a channel on the mixer. »»Suggested attenuation setting: -20dB (line level) or -40dB (amp level) ««
DJ Console Output Signals - DJ Mixers often supply only an unbalanced -10dB signal. The ADP21 converts this signal to a balanced line level before it reaches the house console, while providing a convenient method of connector transition with long cable run capability. »»Suggested attenuation setting: 0dB or -20dB««
Speaker Level Signals - The ADP2's capability of accepting speaker level input from an amplifier's output allows post-amplifier, post EQ/effects signals to be fed directly to the console. This is particularly desirable where a tube guitar amp is concerned. »»Suggested attenuation setting: -40dB««
CAUTION! If you are connecting a "tube" amplifier's speaker output this way, BE SURE A SPEAKER LOAD IS ALSO CONNECTED. Tube amps must see a load impedance that falls within their design parameters. Because it has a very high input impedance, connecting the ADP2 in parallel with a speaker load will not alter the overall speaker load impedance encountered by the amplifier.
