Connect the included microphone to the PXI-H990.
Refer to the Installation manual.
• When combined with a separately sold monitor that is Road EQ compatible and the Road
Equalizer function are used, the separately sold monitor’s built-in microphone can be
used.
• When connecting two PXI-H990 units, connect the microphone to both units. In this case,
the built-in microphone in the separately sold monitor cannot be used.

Secure the microphone in place.
Failure to fix the microphone securely in place may result in distortion or
improper acoustic positioning. The microphone must be mounted very
securely so the bass frequencies will not vibrate it. For example, fasten
using the fitting included with the sun visor, etc.
If the partition is a metal sheet,
open a hole in the rear tray.
If you encounter a problem,
consult your authorized dealer.
Is the partition a
metal sheet?
Or move the subwoofer
into the cabin.
• Do not disconnect the microphone during the automatic adjustment procedure.
• The adjustment differs according to the position
of the microphone. Search for the position at which
the desired sound quality can be achieved.
• The proper adjustments cannot be achieved if the
subwoofer is located in the trunk and the trunk and
cabin are separated by a metal sheet. Either move
the subwoofer into the cabin or open a hole in the
rear tray to join the two spaces. (This is not necessary
if the partition is not a metal sheet.)
