Setup guide
PXE-H650 INSTALLATION & USAGE
TIPS
-
Output
channels
configuration:
• Amp gains
must
be set so that speaker levels (SPL) are matched prior to MultEQ
calibration. This will help assure that one
or
more channels do
not
clip the MIC
input
during measurements.
•
To
assist with setting proper amp gains, the
AUX
input
clip
LED
functions
as
a MIC
input
clip indicator during MultEQ calibration. The clip
LED
must
not illuminate at
any time during the calibration procedure for if it does, the acoustic measurements will
not
be accurate.
• The
SUB
channel
is
the most likely
to
clip the MIC
input
due
to high
SPL
compared
with FRONT
and
REAR
channels. Check to make sure that the
SUB
level
is
matched
to the FRONT
and
REAR
speakers and that the clip
LED
is
not
illuminating during
calibration.
• Recommended starting amp gain levels prior to MultEQ calibration:
- FRONT and
REAR
amp gains are set
to
1/
2
positions (nominal)
- SUBWOOFER amp gain
is
set
to
1/
4
position (9 o'clock)
Once MultEQ calibration is completed, final adjustment of amp gains
should
be carried
out
to suit the taste of the system user.
•
If
MIC
input
clip
LED
illuminates at any time during 1st MIC position measurement,
amp levels
must
reduced and 1st MIC position
must
be repeated.
MAIN
(speaker
level)
input
configuration:
Input
channels:
• One pair
of
full-range stereo inputs (L &
R)
is
all that
is
needed by the PXE-H650 for
proper operation. If full range stereo inputs are available from the factory system, they
should
be connected to the L2IR2 channels
of
the MAIN (speaker level)
input
harness.
•
If
the vehicle has factory crossed over speaker outputs, both high pass (tweeter)
and
low pass (midrange) signals must be connected to the MAIN inputs for proper full-
range signal input. The factory subwoofer
output
may also need to be connected to
achieve a full-range signal.
Polarity:
•
All
OEM head units that are connected to the MAIN
input
harness must be wired
in
phase, observing correct polarity.
• Reversed polarity on MAIN
input
channel connections can be detected during the
"ADJUST XOVER+AMP
LEVELS"
step using Track 3 - Pink Noise prior to MultEQ
calibration.
If
low
or
no speaker
output
is detected
on
LEFT
or
RIGHT channels, check
the polarity of the speaker level inputs
on
that channel.
• After correcting any incorrect wiring polarity, a factory reset should be
done
and
the
PXE-H650 setup procedure
should
be repeated from the beginning.
Setting OEM
head
unit
volume
level
• The OEM head
unit
volume level
must
be set so that it
is
high enough to allow
maximum
system
output
yet low
enough
to avoid a distorted
input
level to the PXE-
H650. 2/3 to 3/4 of maximum volume scale
on
the OEM head
unit
is
recommended.
Storing
custom
settings
permanently
in
memory
• After changing any Custom Tuning parameters, you must remember to navigate to
SAVE
SETTINGS
and
press "ENTER" in order to store these settings permanently
in memory.
