the Volume

g g

g or

h h

h buttons to select LARGE. The surround speakers will operate full range

(20 Hz to 20 kHz).

5. If they are not designed for low frequencies, select SMALL/THX. The surround speakers will

have low frequencies rolled off 12 dB per octave starting at 80 Hz. This low frequency

information is then rerouted to the subwoofer channel.

channel information into the front speakers.

Trim button for three seconds to exit BASS MGMT SETUP and return to normal operation.

built into the AVC-2500. If your subwoofer has no switch to bypass or defeat its built in

crossover, set it to its highest crossover frequency.

Setting the Bass Limiter:

With the extra low frequency content mixed into film soundtracks, especially in the LFE channel,

it is sometimes preferable to limit overall bass energy to prevent overloading your speakers

and/or subwoofer. The Bass Limiter is designed to protect woofers from over excursion,

distortion, or damage. When in doubt, leave the Bass Limiter at its default 0 dB setting and use

sensible master volume levels.

Use caution when setting the Bass Limiter since high volume levels are required

during this adjustment.

1. If you are not already in the Bass Management setup menu, follow steps 1 and 2 above.

2. Press the Tune

f f

f or

e e

e buttons until BASS LIMITER and 0 dB appear in the displays.

3. Press the Mem/Enter button to engage the noise generator. The Bass Limiter is then set to

its -55 dB maximum level. At the same time, the master volume is turned up to the maximum.

4. Press the Volume

g g

g or

h h

h buttons to slowly raise the Bass Limiter level from -55 dB until

the any of the woofers in the system start to “overload”. When this happens, you may hear

some mechanical clattering sound or other evidence of distress. Sometimes the noises you

hear are not produced by the subwoofer, but are objects that are vibrating or rattling.

5. Quickly reduce the Bass Limiter level until you can no longer hear the distortion, clattering,

or other unmusical sounds from any of the woofers in the system.

6. The Bass Limiter is now set to its optimum level. Typical Bass Limiter settings should

generally be around -20 dB.

7. Press the Setup/Trim button to advance to SPEAKER LEVEL SETUP, or press and hold the

Setup/Trim button for three seconds to exit BASS MGMT SETUP and return to normal operation.
