Speaker Levels
Speaker level calibration allows you to equalize the volume levels of each speaker to make up for differences in
speaker characteristics and distances from the listener to the speakers. For best results it is important that you
perform this calibration when you initially install your receiver, whenever you change speakers, and whenever you
rearrange your listening area. The following adjustment must be done for proper room calibration to THX
reference level. Sit or place the SPL (Sound Pressure Level) meter in your normal listening spot. Check that you
are in SETUP SPEAKERS and that your remote is in B&K mode. Note that if you have turned a speaker OFF in
the SPEAKER SIZE SETUP menu then you will not be able to select that speaker in the SETUP SPEAKER
LEVELS menu. Set the SPL meter to use 75 dB SPL, C Weighting and SLOW response. Adjust each speaker’s
level up or down to achieve the desired THX reference level of 75 dB SPL.
Note: if you must do this adjustment with out the aid of an SPL meter, you may do it by ear and adjust each
speaker for equal volume. You may wish to go through the speakers several times to get a reasonable result.
Also note that the VOLUME on the remote will not function in this menu.

Crossovers + LFE
Usually these settings may be left set to the factory defaults. However, your receiver allows ‘fine tuning’ of the
system parameters most useful in setting up a high-end audio system.
Set the high and low pass filters’ crossover frequency - This sets the frequency at which bass tones are
removed from the small main speakers and sent to the subwoofer. If you use very small main speakers you may
wish to raise the crossover above 80 Hz. You may get better results with fairly large speakers by setting them to
small and using a low crossover frequency so only the lowest tones are sent to the subwoofer. THX certified
speakers are specifically designed for use with an 80 Hz crossover setting.
