(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.

Specifications
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. Set the
GUITAR/SPEAKER (3)
switch to GUITAR for this
application. 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 paral-
leled 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. Set the
GUITAR/SPEAKER (3)
switch
to SPEAKER for this application. 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.
