Setup Menu Level Four - Calibrating Channel Delay Times
The AVC-2500 is equipped with advanced circuitry that automatically calibrates your home
theater speaker delay times. The easiest method to calibrate the delay times in your home
theater system is with Automatic Calibration.
Note: Because subwoofers employ different cross-over designs, and are especially dependent
on room acoustics, automatic calibration of subwoofer delay times may not work on all
subwoofers. For reliable results, you should confirm subwoofer delay times manually.
To Automatically Calibrate Channel Delay Times:
1. Connect the ACM-2500 Calibration Microphone to the Cal Mic jack on the front panel.
2. Locate the calibration microphone upright at ear level at your listening position.
3. Press and hold the Setup/Trim button on the remote control until
SOURCE SETUP appears
on the front panel or on-screen display.
4. Press Setup/Trim until SPEAKER DELAY SETUP appears in the displays.
5. Press the A. Cal button on the remote control for two seconds.
6. The on screen display background turns red as
AUTO CALIBRATION appears in both displays.
7. The AVC-2500 will again engage its internal noise sequencer and adjust all the individual
channel delays, except the sub channel, whose delay must be calibrated manually. Keep
the calibration microphone upright at ear level and hold it steady during this procedure.
This operation requires several minutes, so please be patient.
8. When calibration is complete, AUTO CALIBRATION COMPLETE appears in the displays.
9. Press Setup/Trim to advance to OSD SETUP , or press and hold the Setup/Trim button for
three seconds to exit SPEAKER DELAY SETUP and return to normal operation.
To Manually Calibrate Channel Delay Times:

theater speakers. If you have two subs, use the distance that is the average of both of
them to your listening location.
2. Press and hold the Setup/Trim button on the remote control until SOURCE SETUP appears
on the front panel or on-screen display.
