When using the Acoustic Calibration EQ Professional
(see page 43) to calibrate the reverb characteristics of
your listening room, you can graphically check the
results on your computer connected to this receiver.
Also, when the Full Band Phase Control function is
activated, you can visually check the calibrated
characteristics of group delay of the speakers and the
corrected characteristics of group delay processed by the
exclusive correction filter by installing the corresponding
PC application on your computer.
Use a commercially-available RS-232C cable to connect
the RS-232C jack on your computer to the 9-pin RS-232C
jack on the back panel of this receiver (the cable must be
cross type, female-female).
The software to output the results is available by
contacting the Pioneer Authorized Distributor for your
area (as listed on page 95 of this manual) as well as the
instructions necessary for using it.

K6 / 300 MHz (or equivalent) with at least 128 MB of

• An RS-232C port connector is necessary for graphical
output. Refer to the operating instructions and/or the
PC manufacturer for more information on making
the proper port settings.
• System must have internet access.
• Connect your computer to the RS-232C jack on
the rear panel of the receiver.
