Calibrating the AS-EQ1 in Your Listening Environment
Your EQ-equipped AVR or Pre/Pro normally handles the full frequency range of your system which includes
the subwoofer and main speakers. The AS-EQ1 is designed to handle the lower frequencies where your
subwoofer(s) operate, and apply its own, more sophisticated correction filters in the place of that provided
by your AVR or Pre/Pro. This task will effectively set your AVR or Pre/Pro to equalize only the main (and
Satellite) speakers in your system so the AS-EQ1 can assume the EQ of the subwoofers and not have any
overlap of EQ filters in your system.
(see Fig. 11 below and Fig. 12 on page 17)
1. Carefully remove the front panel of your AS-EQ1. It is attached magnetically and should pull off easily.
2. Take the Calibration Microphone from your AVR or Pre/Pro (NOT the Calibration Microphone from the
AS-EQ1) and plug it into the Pass-through Mic In jack located on the front of the AS-EQ1. (see Fig. 12)
3. Locate the calibration microphone “patch cable” that came with your AS-EQ1 (1/8” mono male connectors
on each end). Plug one end into the AS-EQ1’s Passthrough Mic Out jack, and the other end into the
Calibration Microphone input jack on your AVR or Pre/Pro.
4. On the Sub EQ GUI running on your PC, make sure the “On” Radio Button has been checked on the Auto
EQ Assist screen (Note: Navigating away from this screen (forward or back), exiting the Sub EQ GUI, or
powering off the AS-EQ1device will turn external calibration mode to Off).
5. Calibrate the AVR or Pre/Pro as directed by its owner’s manual. Note: Your subwoofer will be “detected”
during the AVR’s calibration process although you will hear no sound from the sub.
