(2) GROUND LIFT BUTTON When pressed, this disconnects the ground connection between the 1/4" input and XLR output to eliminate hum caused by ground loops. 2 ADI1manual 2 10/2/03, 9:53 AM 3 Operation (6) (7) Connected to Instrument The ADI-1 can be used to connect the unbalanced output of an instrument or line level device (eg. guitar, bass, synthesizer, effects module, another mixer) to the balanced input of a mixer or amplifier. If you desire to send the original unbalanced signal on to a mixer or amplifier, use the 1/4" UNBALANCED OUTPUT (5). The 1/4" OUTPUT (5) is paralleled with the input, therefore, when using the 1/4" OUTPUT (5), the input device and output device volume controls may need to be adjusted to acquire the desired level. Connected to Amplifier The ADI-1 can be used to connect an amplifier's speaker output, or a speaker's "daisy chain" output, to the balanced input of a mixer. If your speaker has only one connector, the ADI-1 can be inserted between the amplifier and speaker using the 1/4" INPUT (4) and 1/4" OUTPUT (5) jacks. (3) SPEAKER/GUITAR SWITCH Switch enables a 35dB pad when set to SPEAKER, allowing the input to receive high level signals from speaker or amplifier outputs. (4) 1/4" INPUT Unbalanced 1/4" input jack for inputting a line level, instrument level, or speaker level signal. (5) 1/4" OUTPUT Unbalanced 1/4" output jack which is in parallel with the input jack. This allows the ADI-1 to be used as a Y-splitter by sending the input signal to another device via the 1/4" output as well as sending it from the balanced XLR output. (6) XLR OUTPUT Balanced XLR output jack [Pin 1 = Ground, Pin 2 = Hot(+), Pin 3 = Cold(-)] (7) BATTERY COMPARTMENT Remove screw and panel to install 9V battery.
