Input sound through the DIGITAL IN terminals (COAXIAL
(VIDEO 2), OPTICAL (VIDEO 1) and OPTICAL (DVD)) cannot
be recorded. When recording the sound from the DVD, CD, MD
or LD player, connect the analog AUDIO OUT terminals of the
player to the corresponding AUDIO IN terminals of the receiver.
With this connection, the picture noise may appear when playing
copy protected DVDs. In this case, it is recommended to connect
the VIDEO OUT terminal of the DVD player directly to a TV set,
not through the receiver.
When connecting an LD player equipped with theAC-3 RF OUT
terminal, use an RF demodulator unit. Also connect the analog
AUDIO OUT terminals of the LD player to the receiver to play
all the sources. For further information, refer to the instructions
of the LD player.

achieve the same apparent loudness, at your listening position,
from each channel.
Press SUBWOOFER +/-, CENTER +/- or REAR +/-
on the remote control.
Each speaker level can be changed within the range from –10
dB to +10 dB at 1 dB steps.
