y
• We recommend connecting the coaxial digital output terminal of a CD player to the AV3 jack.
• When connecting a turntable with a low-output MC cartridge to the PHONO jack, use an in-line boosting transformer or MC-head amplifier.
• Connect your turntable to the GND terminal of this unit to reduce noise in the signal.
About audio/video output terminals
Among the analog audio and analog video signals input to this unit via input terminals, the audio/video signals of the
selected input sources are output from the AV OUT jack and AUDIO OUT jack. An HDMI input signal,
COMPONENT VIDEO input signal or digital audio input signal cannot be output.
When using the AV OUT jack: connect an external component to the composite or analog audio terminal.
When using the AUDIO OUT jack: connect an external component to the analog audio terminal.
Connecting a multi-format player or an
external decoder
This unit is equipped with 8 additional input jacks (Front
L/R, Center, Surround L/R, Surround Back L/R and
SUBWOOFER) for discrete multi-channel input from a
multi-format player, external decoder, etc. If you set input
source to "MULTI CH," the analog audio input jacks
assigned as "Front Input" can be used as the front channel
input jacks.
Notes
• When you select "MULTI CH" as the input source, the digital sound field
processor is automatically disabled.
• Since this unit does not redirect signals input at the MULTI CH INPUT
jacks to accommodate for missing speakers, connect at least a 5.1-
channel speaker system when using this feature.
• When the input source is switched to "MULTI CH," images input from a
component connected to "AV1-6" or "V-AUX" (see page 36). If your
DVD player does not support multi-channel digital output, connect it to
these input jacks.

Connecting an external amplifier

This unit has more than enough power for any home use.
However, if you want to add more power to the speaker
output or if you want to use another amplifier, connect an
external amplifier to the PRE OUT jacks. Each PRE OUT
jack outputs the same channel signals as the
corresponding SPEAKERS terminals.
Note
• When you make connections to the PRE OUT jacks, do not make any
connections to the SPEAKERS terminals.
