TEST TONE:

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.

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.
