PREPARATIONS

*1 When connecting a monaural video recorder, use astereo-monoconnecting cord (not supplied).

*2 When connecting an LD player equipped with theAC-3RF OUT terminal, use an RF demodulator unit. Also connect the analogue

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.

*3 Input sound through the 5.1CH INPUT or 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 analogue AUDIO OUT terminals of the player to the corresponding AUDIO IN terminals of the receiver.

*4 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.

DVD PLAYERS CONNECTIONS

To connect a DVD player without a decoder, connect the player

 

to the DIGITAL IN terminals of the unit.

 

To connect a DVD player with a decoder and 5.1 ch output

 

terminals, connect the player to the 5.1CH INPUT terminals of

En

the unit.

The 5.1CH INPUT terminals can also be used when connecting a digital TV with multi-audiooutput terminals.

CONNECTING SPEAKERS 1

Speaker terminals

There are three types of speaker output terminals.

Screw type (FRONT SPEAKERS A)

The speaker terminal is opened by turning it counterclockwise. After inserting the stripped wire into the terminal slot, tighten down by turning it clockwise to secure the wire.

Flap type (FRONT SPEAKERS B, SURROUND SPEAKERS and CENTER SPEAKER)

The speaker terminal is opened by lifting the terminal flap. After inserting the stripped wire into the terminal slot, close the flap to lock the wire in place.

Jack type (SUB WOOFER)

Simply plug in the sub woofer cord here.

Connect front speakers (system A and/or B), a centre speaker, surround speakers and a sub woofer to the corresponding speaker terminals on the unit:

-the front speaker cords to the FRONT SPEAKERS terminals

When connecting only one set of front speakers, connect them to the FRONT SPEAKERS A terminals.

The FRONT SPEAKERS B terminals (speaker system B) are for use of 2 channel stereo system only.

-the centre speaker cord to the CENTER SPEAKER terminals

-the surround speaker cords to the SURROUND SPEAKERS terminals

-the sub woofer (with a built-inamplifier) cord to the SUB WOOFER jack, for more powerful bass sounds

-When not connecting the sub woofer, be sure to select " " (sub woofer off) mode (see the next page).

-When not connecting the centre speaker and/or surround speakers, and regarding to the size of speakers (including front speakers), speaker settings must be done. Before using the unit, be sure to make speaker settings in accordance with your speaker configuration (see page 16).

Speaker impedance

For all speakers, use speakers of 8 ohms or more.

Connecting +to+,-to-terminals

To get the proper sound effect, the speaker terminals on the unit and the speaker should be connected with proper polarity; the +terminal on the unit should be connected to the +terminal on the speaker (and -to-).
