If your AVR or Pre/Pro has an auto-set-up/EQ system which is NOT based on Audyssey technology, make sure

you have completed the Auto EQ Assist task as outlined earlier in this Manual before proceeding.

If you are not using any form of auto setup on your AVR or Pre/Pro it is assumed that you have already manually

level matched your SAT speakers, and also know your “Reference” Master Volume setting. The Reference

Master Volume setting is used for calibrating the speakers to 75 dB when playing the internal test tones. This

Master Volume setting is usually 0.0 on THX compliant systems, but may be different for AVRs or Pre/Pros us-

ing a different volume scale.

Please note the Reset button below the SAT and SUB measurement boxes. Because SubEQ 3.2 uses a

C-weighted Leq measurement method (essentially a running average of the sound pressure level) it is impor-

tant to note that if you change levels of your SAT or SUB(s), it will be necessary to click the Reset button each

time in order to clear the measurement buffer and establish a new measurement. Failure to click the Reset

button when you make a level change to your SAT or SUB will result in very slow changes to the displayed

value and inaccurate data.

Make note the current/existing trim setting in the AVR or Pre/Pro speaker set-up menu for the connected SAT

channel. With the SAT measurement box selected, click the Measure button. Adjust the trim level (NOT the

Master Volume) for that SAT channel until the box turns green and you obtain a steady reading at/near 0.0 (which

equates to 75 dB +/- 3 dB). Remember to click the Reset button as needed as you make trim level adjustments.

Make a note of the new trim level setting for the connected SAT channel. Subtract the new setting from the

previous setting and then take the inverse of this value. This is your SAT trim differential. In your AVR or Pre/Pro

set-up menu, apply this SAT trim differential to all other existing trim settings for the remaining speaker

channels. This will save you the time of connecting all the other speaker channels to the AS-EQ1, and will also

preserve the relative differences between all the speaker channels, only adjusting them for absolute volume.

Examples are presented on the following page.

NOTE:

If your AVR or Pre/Pro is NOT equipped with Audyssey MultEQ, then follow instructions

contained in this section.
