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.
