Controls and Connections, ON/OFF Switch

Controls and Connections

(1) ON/OFF SWITCH

When set to ON, this enables the 9V battery power for the unit. If the device connected to the ADI-2 XLR output has 25V-48V phantom power enabled, the ADI-2 can be used without draining the 9V battery. Disabling the ON/OFF button will save battery power when using phantom power. Always remember to turn off the ADI-2 ON/OFF switch when not in use to preserve your battery.

CAUTION: Always turn on the ADI-2 before turning up the volume on devices connected to the ADI-2 outputs to avoid damaging your equipment or speakers.

(2) GROUND LIFT SWITCH

When set to LIFT, this disconnects the ground connection between the 1/4" input and XLR output to eliminate hum caused by ground loops.

(3) SPEAKER/GUITAR BUTTON

When pushed in, this enables a 35dB pad, allowing the input to receive high level signals from speaker or amplifier outputs.

(4) 1/4" INPUTS

Unbalanced 1/4" input jack for inputting a line level, instrument level, or speaker level signal.

(5) 1/4" LINK OUTPUTS

Unbalanced 1/4" output jack which is in parallel with the input jack. This allows the ADI-2 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 OUTPUTS

Balanced XLR output jack [Pin 1 = Ground, Pin 2 = Hot(+), Pin 3 = Cold(-)]

(7) BATTERY COMPARTMENT

Remove screw and panel to install 9V battery.
