Caution:
� Be sure to always refer to the instructions that came with the component that you are connecting. � Do not plug in the power cord until all connections have been made. � Do not make connections to input or output jacks while the ADM-2.1 is turned on. � Always turn the volume of the control amplifier or preamplifier down before turning on the ADM-2.1. � For input and output jacks, red connectors (marked R) are used for the right channel and white connectors (marked L) are used for the left channel. � Insert all plugs and connectors securely. Improper connections can result in noise, poor performance, or damage to the equipment. Improper connection

GND
Use this GND terminal for connecting the ground (or earth) wire of other component if humming noise is heard.

TRIGGER
Set this TRIGGER switch before turning on the ADM-2.1. To turn on the ADM-2.1 with the signal input from the 12V TRIGGER IN jack, set the TRIGGER switch to 12V TRIGGER. To turn on the ADM-2.1 with the signal input from the AUDIO IN jack, set the TRIGGER switch to AUDIO (Auto Power On/Off Function). If you do not use Auto Power Function, set the TRIGGER switch to OFF.

AUDIO IN/OUT
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 AUDIO IN jacks on the ADM-2.1. When connecting a control amplifier or preamplifier, connect the PRE OUT jacks to the AUDIO IN jacks. If you connect the AUDIO OUT jacks of the ADM-2.1 to the AUDIO IN jacks of another ADM-2.1, the signal input at the AUDIO IN jacks of the ADM-2.1 is also output from the AUDIO OUT jacks (Audio In/Out Link Function). If you set the TRIGGER switch to AUDIO, the power of the connected ADM-2.1 turns on automatically when an audio signal is supplied to the AUDIO IN jacks (Auto Power On/Off Function).

12V TRIGGER IN
If the connected control amplifiers or preamplifiers have a 12V TRIGGER output jack, use 1/8-inch 2P mini-jack cable to connect the 12V TRIGGER IN jack on the ADM-2.1. This jack works on between 5 to 12 volts DC. When the ADM-2.1 is in the standby state and the TRIGGER switch is set to 12V TRIGGER, you can switch the ADM-2.1 between the on and standby states with operations at the control amplifier or preamplifier. Note: When a plug is connected to the 12V TRIGGER jack, be sure to connect the analog output jacks (or PRE OUT jacks) of the device to the AUDIO IN jacks of the ADM-2.1. Otherwise, no sound will be produced.

INPUT LEVEL
Turn this INPUT LEVEL control to adjust the input level of the signal from the AUDIO IN jacks. Normally, set to MAX. Note: When a CD player is connected to the ADM-2.1, be sure to adjust the INPUT LEVEL control.
