To Setup Bass Management for your Surround Speakers:

1.If you are not already in the Bass Management setup menu, follow steps 1 and 2 from above and use the Tune f or e buttons until SURROUND and LARGE appear in the displays.

2.Press the Volume g or h buttons to select either SMALL/THX, LARGE, or NONE.

3.Refer to the owner’s manual of your surround speakers to determine whether they are designed to reproduce frequencies below 80 Hz.

4.If the surround speakers are designed to safely reproduce frequencies below 80 Hz, press the Volume g or 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.

6.If you do not have surround speakers, select NONE and the AVC-2500 will blend the surround channel information into the front speakers.

7.Press the Tune e button to advance to Subwoofer Bass Management options, or press and hold the Setup/Trim button for three seconds to return to exit BASS MGMT SETUP and return to normal operation.

To Setup Bass Management for Your Subwoofer:

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

2.Press the Tune f or e buttons until SUBWOOFER and YES appear in the displays. Press the Volume g or h buttons to select either YES or NO.

3.Select YES if you are using a subwoofer. Low frequency effects (LFE) are then routed to the subwoofer. If you have selected SMALL/THX or NONE for the Main, Center, or Surround speakers, frequencies below 80 Hz are also routed to the subwoofer channel.

4.Press the Volume g or h buttons to select NO if you are not using a subwoofer. Low frequency effects (LFE) are then evenly distributed to the Main, Center, and Surround speakers as specified.

5.Press the Tune e button to advance to bass limiter settings, or press and hold the Setup/ Trim button for three seconds to exit BASS MGMT SETUP and return to normal operation.

6.For proper operation defeat the low pass crossover in your powered sub and use the crossover 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 or 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 or 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.
