BASIC OPERATION
MultEQ Calibration
At this point in the process, a baseline response curve has been created and stored for
your specifi c vehicle. This curve ensures that the MultEQ algorithms are working with
a reasonably neutral sounding curve. This eliminates all the peaks and dips in the source
unit, making MultEQs job much easier.
1. "ENTER TO START MULTEQ" - Prepare vehicle for calibration
Make sure the MultEQ LED and microphone are connected (TIP: LED is OFF if
no mic connected). The MultEQ LED is Green and blinks at 1Hz when LED and
Microphone are properly connected.
The microphone should be placed in the primary listening position (normally the
driver's seat). This position is saved as PRESET 1 and is used as the reference for
all further DSP calculations. Plan to use at least 6 different positions for optimum
performance (minimum is 4 and maximum is 8 positions)
Press "ENTER" to start the MultEQ calibration procedure. The MultEQ LED blinks
slowly (1 Hz) during normal operation.
2. "CONNECT LED & MIC"
If the PXE-H650 does not detect the microphone, "CONNECT LED & MIC" is
displayed and the MultEQ LED blinks quickly. Troubleshoot the microphone to ensure
proper operation and connection. The system will continue automatically when the
microphone is detected.
3. "MEASURE POS 1" - Prepare to run the calibration test
If the Mic checks out in Step 2 above, the MultEQ LED is blinking slowly.
Position the Mic in location 1 and exit the vehicle. Close all windows.
Press MEASURE on the remote control to begin (see Page 7).
4. "CHK OUTPUTS & MIC" - Speaker detection Error
If there was a problem during the Speaker Detection process, the PXE-H650 displays
the above error display on the LCD and the LED will blink quickly. Troubleshoot the
system by making sure that nothing has become disconnected or turned off.
Press the reset button after correcting any problems. Navigate to "RECALIBRATE
MULTEQ" in the display. Press "DONE" on the remote control to fi nalize MultEQ
fi lter calibration or "MEASURE" to the next mic position of calibration. The LED
blinks slowly between position measurements.
