REAR PANEL SWITCH AND CONTROL SETTINGS

There are several switches and controls on the rear panel that

you'll have to check before operating your system, and it's a good

idea to do it before you connect cables. Locate the MAIN LEVEL

slide switch (3) and FRONT MIX slide switch (D). Make sure the

MAIN LEVEL switch is set to "0 dB" and the FRONT MIX switch is set

to "OFF" for 7 or 6 speaker driving.

In a 5 or 4 speaker system, set the FRONT MIX switch to "ON".

Next, set the NTSC/PAL switch (B) to the position corresponding

to the standard which your video equipment employs. (General Model

only)

GENERAL INSTRUCTIONS FOR CONNECTIONS

Make sure that you have the left (L) and right (R) channels

correctly connected. That means that jacks marked "L" on this unit

must be connected to jacks marked "L" on other units. Likewise with

the "R" jacks. This is easy if you remember to always use the red plug

for the "R" jacks and the white plug for the "L" jacks.

With speaker connections you must also be sure that the polarity

is correct. For each amplifier and each channel, connect the plus (+)

terminal of the amplifier to the plus terminal of the speaker, and

connect the minus (–) terminal of the amplifier to the minus terminal

of the speaker. To keep track of polarity, use a speaker cable that has

one of the two wires marked by a stripe or a different color.
