Connect the wires from your speakers to the appropriate output on the amplifier.
It is absolutely essential that you observe correct polarity in these connections.
Example: If you connect your right front output of your preamplifier to channel 1 input
on the amplifier, remember to connect your right front speaker wires to channel 1's
outputs. Always observe polarity when connecting speakers, connect amplifiers (+)
to the speakers (+) and amplifiers (-) to speakers (-).

Double check all connections.

Plug the amplifier’s power cord into the AC power source. Turn the amplifier’s
power switch ‘on’. The panel light should be illuminated. Leave the preamplifier
turned off. Before proceeding to the next step turn the amplifier off and wait 30
seconds for the amplifier to discharge. Both the preamplifier and amplifier should
be off.

Connect a playback unit (CD, VLD, Tuner, etc...) to the preamplifier. Turn the
volume on the preamplifier to minimum. Turn on the preamplifier, then the
amplifier (in that order). Set source on the preamplifier to the playback unit
you’ve just connected. Turn volume up slowly and music should be heard from
all channels. If this is not the case, double check your installation.

Should you encounter any problems that cannot be traced to the source or the
material being played, consult the “TROUBLESHOOTING” section on
page 11.
Note: When turning equipment ‘off’, the amplifier should always be turned off first, then
the preamplifier. When turning equipment ‘on’, the preamplifier should always be turned
on
first, then the amplifier. Before turning anything on, ensure the preamplifier is at a
low volume level.
