Multi-channel sound tracks from contemporary action

movies and other digital music sources can include intense

low frequency bass sound effects and energy. Damage to

your subwoofer or other large full range speakers could oc-

cur during extremely loud passages. The BASS LIMITER

feature protects your loudspeakers by allowing you to de-

termine the maximum safe bass levels, and keep the system

from exceeding these safe volume levels. Follow the in-

structions below to calibrate the BASS LIMITER.

Note: Before performing the BASS LIMITER calibration, you

FIRST must have performed the SPEAKER SIZE,

SPEAKER TIME DELAY and SPEAKER LEVEL

adjustments.

1. Press Remote Control pushbutton number 3, to access

the BASS LIMITER MENU from the SPEAKER

LEVEL MENU.

Note: The very first time the BASS LIMITER MENU is

accessed, the factory default setting of LIMITER LEVEL

0 will be indicated on the screen.

2. Press pushbutton 1 to access the BASS LIMITER

SETUP MENU.

3. Press pushbutton 1 a second time to select LIMITER

ON.

4. Press pushbutton number 2 to access the Limiter cali-

bration mode. Refer to Figure 14

CAUTION:

 Use extreme care when performing the next steps

to CALIBRATE THE BASS LIMITER to prevent

possible loudspeaker damage.

5. Press a LEVEL Up pushbutton the remote Control until

the test signal becomes audible from your subwoofer.

If you have no subwoofer, the test signal will be au-

dible from your other Large loudspeakers.

6. Using the LEVEL Up pushbutton, gradually increase

the test signal volume level until you detect evidence

that the subwoofer or other Large loudspeakers are

reaching their limit of undistorted output. An indication

that the loudspeakers are approaching their limit, is a

change in the sound character of the test signal.

7. Press pushbutton E to exit the BASS LIMITER SETUP.

The BASS LIMITER function will be turned ON and

the maximum bass volume level will never exceed the

level reached in Step 6. You will also exit to the MAIN

SYSTEM SETUP MENU.

8. Press E a second time to exit the MAIN SYSTEM

SETUP MENU and the Adjustment Acceptance

MENU will appear on the screen. Refer to Figure 7

9. If you are satisfied with adjustments you have made,

press number 1 on the Remote Control for YES. The

changes will be saved in memory and you will exit the

Setup Mode to normal operation.

10. If you are not satisfied with the adjustments or

changes you have made, press number 0 on the remote

control for NO. The Setup Mode will exit to normal

operation without saving the changes in memory.
