Normally set to “0 dB”. If desired, you can decrease the main-
channel output level at the MAIN speaker terminals by 10 dB by
setting this switch to “–10 dB”.

4

Pre Out Jacks

Main-channel line output. Connected with jumper bars to MAIN
IN jacks when the built-in amplifier is used. Connected to input
jacks of external stereo power amplifier (MAIN IN or TAPE PLAY
jacks of integrated amplifier or receiver) when using external
amplification.

5

Main In Jacks

Line input to built-in main-channel amplifier. Connected with
jumper bars to PRE OUT jacks when the built-in amplifier is used.
Not connected when using an external power amplifier.

6

Main Speaker Terminals

When using this unit’s built-in main-channel amplifier, connect the
main speakers here. The jumper bars must be plugged in to
connect the MAIN IN jacks to the PRE OUT jacks.

7

Front Effect Speaker Terminals

When using the built-in front-channel amplifier, connect the front
effect speakers here.

8

Center Speaker Terminals

When using the built-in center-channel amplifier, connect one or
two center speakers here.

9

Center Speaker Impedance Switch

Set to “A + B” when using two center speakers, or to “A OR B”
when using only one center speaker.

0

Rear Effect Speaker Terminals

When using the built-in rear-channel amplifier, connect the rear
effect speakers here.

A

GND Terminal

Connects the ground wire of the turntable to produce minimum
hum. In some cases, however, better results may be obtained
with the ground wire disconnected.

B

Video NTSC/PAL Switch (General Model only)

Set this switch to the position corresponding to the standard
that your video equipment employs.

C

Front Effect Out Jacks

Front-channel line output. Not connected when the built-in
amplifier is used. Can be connected to input jacks of an
external stereo power amplifier driving the front effect
speakers.

D

Front Mix Switch

Set to “OFF (7ch)” when setting up a full 7 or 6 speaker system,
or to “ON (5ch)” when setting up a 5 or 4 speaker system.

E

Rear Effect Out Jacks
