Notes on connecting with an LD player equipped with an AC-3 RF output

English

If your LD player has AC-3 RF signal output terminal and no digital signal output terminal for AC-3 discrete audio signals, connect the AC-3 RF signal output terminal to this unit’s OPTICAL (or COAXIAL) digital signal input terminal by using an RF demodulator (separate purchase).

First, connect the AC-3 RF signal output terminal of the LD player to the AC-3 RF signal input terminal of the RF demodulator. Next, connect the optical (or coaxial) digital signal output terminal of the RF demodulator to the OPTICAL (or COAXIAL) digital signal input terminal of this unit.

This connection is necessary for sending audio signals encoded with the Dolby Digital (AC-3) from the LD player to this unit.

It is also necessary to connect the LD player to this unit’s analog audio signal input terminals 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 terminal (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 terminal of this unit, and connect the RF demodulator to the OPTICAL digital signal input terminal of this unit.

By this connection, if the input mode of the DVD/LD source is in “AUTO”, you can enjoy listening to sounds with the Dolby Digital (AC-3) decoded when you play a disc encoded with the Dolby Digital (AC-3) though signals are input to both OPTICAL and COAXIAL digital signal input terminals of this unit simultaneously (because signals input to the OPTICAL terminal take priority of signals input to the COAXIAL terminal).

See page 29 for details about switching the input mode.

Notes

●If your LD player has an OPTICAL digital output terminal (for 2-channel audio signals), be sure not to connect it to this unit’s OPTICAL digital input terminal. If you do so, when you play a disc encoded with the Dolby Digital (AC-3), the Dolby Digital (AC-3) will not be decoded because the 2- channel audio signals input to this unit’s OPTICAL digital input terminal are selected prior to the signals encoded with the Dolby Digital (AC-3) input to this unit’s COAXIAL digital input terminal by way of an RF demodulator.

●If, for example, you play a CD on the LD player (which can play a CD also), there is no input to the OPTICAL terminal, so the signals input to the COAXIAL terminal 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.
