Notes on connecting with an LD player equipped
with an AC-3 RF output
If your LD player has AC-3 RF signal output jack and no digital
signal output jack for AC-3 discrete audio signals, connect the AC-
3 RF signal output jack to this unit’s OPTICAL (or COAXIAL) digital
signal input jack by using an RF demodulator (separate purchase).
First, connect the AC-3 RF signal output jack of the LD player to
the AC-3 RF signal input jack of the RF demodulator. Next,
connect the optical (or coaxial) digital signal output jack of the RF
demodulator to the OPTICAL (or COAXIAL) digital signal input jack
of this unit.
This connection is necessary for inputting audio signals encoded
with the Dolby Digital (AC-3) on the LD player to this unit.
It is also necessary to connect the LD player to this unit’s
analog audio signal input jacks regardless of the AC-3 RF signal
connection, for playing back an LD source with the Dolby Pro Logic
Surround decoded or in normal stereo (or monaural).
If desired, you can also connect the digital signal output jack
(for 2-channel audio signals) of the LD player to this unit. If you will
do so, connect it to the COAXIAL digital signal input jack of this
unit, and connect the RF demodulator to the OPTICAL digital
signal input jack of this unit.
By this connection, if the input mode of the DVD/LD source is in
“AUTO”, you can enjoy listening to sounds decoded with the Dolby
Digital (AC-3) when you play a disc encoded with the Dolby Digital
(AC-3) though signals are input to both OPTICAL and COAXIAL
digital signal input jacks of this unit simultaneously (because
signals input to the OPTICAL jack take priority of signals input to
the COAXIAL jack).
See page 46 for details about switching the input mode.
NOTES
●
If, for example, you play a CD on the LD player (which can play
a CD also), there is no input to the OPTICAL jack, so the
signals input to the COAXIAL jack take priority. In this case,
switch off the RF demodulator to listen to CD sound surely.
However, if your RF demodulator is the Yamaha model APD-1,
you do not have to switch it off.
●
When you want to play a source encoded with the Dolby Digital
(AC-3) without decoding the Dolby Digital (AC-3), you must
switch off the power to the RF demodulator.
