ON/STANDBY button
This button is used to turn the main power on/off.

Power indicator
The power indicator will be lit blue when the main power of ADM-20.4 is turned on.

INPUT LEVEL knob
Turn this INPUT LEVEL knob to adjust the input level of the signal from the INPUT jacks. Normally, set to MAX.
INPUT/OUTPUT jacks
These are the analog audio inputs and outputs. Use an RCA-type audio connection cable to connect the
output jacks of the device to the INPUT jacks on the ADM-20.4. When connecting a control amplifier or
preamplifier, connect the PRE OUT jacks to the INPUT jacks. If you connect the OUTPUT jacks of the ADM-20.4 to the INPUT jacks of another ADM-20.4, the signal input at the INPUT jacks of the ADM-20.4 is also
output from the OUTPUT jacks (Input/Output Link Function).
12V TRIGGER IN/OUT jacks
Connect the 12V TRIGGER IN jack to an AV Receiver that has a 12V TRIGGER output jack. This jack works on between 5 to 12 volts DC. If you want another component to be activated/deactivated by turning on/off the AV receiver connected to the 12V TRIGGER IN jack of the ADM-20.4, connect the 12V TRIGGER input jack of that component to the 12V TRIGGER OUT jack of the ADM-20.4. In this state, the 12V TRIGGER is output when the ADM-20.4 is turned on. Devices can be connected in series using these jacks.
Use 1/8-inch (3.5mm) monaural-type mini-jack connectors or the supplied stereo mini-plug cable.
The tip polarity of the connector is positive.
SPEAKERS terminals
