SUBWOOFER: Set ON if you have a separate sub-

woofer, or powered speaker system that does not have

it’s own bass management/crossover circuitry.

CENTER DELAY: If your center channel speaker is the

same distance or further away than your main speak-

ers set this to 0 mS. If the center channel is closer to

the listener than the main speakers, add 1 mS for each

foot closer to the listener.

REAR DELAY: If the rear (surround) channels are clos-

er to the listener than the front channels are, select

1ms for each foot closer the surround channels are

than the main Left and Right speakers. If the sur-

rounds are the same distance as, or farther away than,

the front speakers set this to 0mS.

TEST TONE:

Use this after you have defined the speaker layout.

When you select ON, a short burst of pink noise will be

sent to each channel in turn. When the system is bal-

anced, each speaker will play at the same apparent

level when heard at the primary listening position. After

selecting ON, let the tone cycle through all of the

channels at least once. If any of the channels appear

louder or softer than the main left and right channels,

they should be adjusted to play at the same volume.

The buttons on the number keypad correspond to the

speakers corresponding to their positions in the pic-

ture on the right half of the TV screen.

1 - Left Front

2 - Center

3 - Right Front

6 - Subwoofer

7 - Left Surround

9 - Right Surround

Press the button corresponding to the speaker requir-

ing adjustment. The Tone will stay on this speaker, use

the volume +/- buttons to adjust the volume level.

Select the next channel to adjust and repeat the

process. Continue until all of the channels play at the

same apparent volume level. Press ) to exit adjustment

mode.

Hint: The adjustment may be made by ear:

however, use of a sound level meter such as Radio

Shack #330-2050 may make the adjustment easier

and more accurate.
