Operating Instructions

Listening to your CD player, tape
deck, tuner or other source

1. Turn Volume control to minimum level and

press the round Power button (above
”Power”) to turn the unit to Standby, the
power indicator below will light orange. Then
press the flat Power switch to turn on the
amplifier. The power indicator lights red for a
few seconds, while the protection circuitry
checks for short circuit or other problems, and
then it lights green.

2. Press “Speaker 1” to hear loudspeakers con-

nected to the rear Speakers 1 terminals. Press
“Speaker 2” to hear loudspeakers connected
to the rear Speakers 2 terminals. Press both to
hear both speaker pairs at once. To listen to
headphones only, press to turn off any active
speaker pair.

3. Select desired source for listening by pressing

the front panel Source button repeatedly until
the indicator for the desired source is illumi-
nated or by pressing the desired Source but-
ton on the remote.

4. Begin playing the desired source.

5. Adjust the Volume control to the desired level.

6. Adjust Bass, Treble and Balance controls as

desired (the Source Direct function must be
turned off).

7. Press "Source Direct" until the "Source

Direct" indicator lights up to bypass the tone
control and balance circuitry to ensure purest
sound performance. Press again to turn the
bypass function off and to make the tone and
balance controls function again.

Making a recording

You may record any source to tape or to CD-R or
to both simultaneously. You may also connect a
second tape deck to the CDR inputs and outputs
to record from tape to tape (in either direction).

To select the desired source for recording (this
can be a different source than the one being
listened to), press the "Record Source" button
on the front panel repeatedly until the indicator
for the desired record source is illuminated.

NOTE: The record output signal is taken directly
from the program source and is unaffected by
the Volume, Bass, Treble or Balance controls.

Important Notes:

• The functions "Source Direct" and "Record

Source" can be selected on the front panel
only, not from the remote control.

• 3-head cassette decks with monitoring func-

tion can be connected to "Tape" or "CDR"
connectors too, but their monitoring function
cannot be used.
