• Do not connect any devices other than speakers to these
terminals.
• Be sure not to mistake the positive and negative outputs or the
left and right speakers. Doing so will result in an unnatural
sound space.
• Only connect speakers with an impedance of 6 ohms or higher.
If a speaker with an impedance of less than 6 ohms is
connected, it may damage the ADM-2.1.
Connection diagram
Since the many users will purchase the ADM-2.1 together with the
DTR-7.1, here is an explanation of how to connect the ADM-2.1 to
the DTR-7.1.

• When you are using only one
speaker or when you wish to
listen to monaural (mono)
sound, a single speaker should
never be connected in parallel
to both the right and left-
channel terminals simultane-
ously.
• To prevent damage to cir-
cuitry, never short-circuit the
positive (+) and negative (–)
speaker wire.
AC INLET
Plug the supplied power cord into this AC INLET and then into the
power outlet on the wall.
• Do not use a power cord other than the one supplied with the
ADM-2.1. The power cord supplied is designed for use with
the ADM-2.1 and should not be used with any other device.
• Never disconnect the power cord from the ADM-2.1 while the
other end is plugged into the wall outlet. Doing so may cause
an electric shock. Always connect by plugging into the wall
outlet last and disconnect by unplugging from the wall outlet
first.
When connecting the ADM-2.1 to 2 channel control amplifier or
preamplifier, connect the AUDIO IN jacks of the ADM-2.1 to the
PRE OUT FRONT jacks of the control amplifier or preamplifier,
and connect the front speakers to the SPEAKERS terminals of the
ADM-2.1.
