Press the switch corresponding to the input source you’d like to calibrate.
The switch LED will begin to ash and *input offset* will be displayed in
the rst line of the LCD screen (see screenshot 7).

“CAL” will be displayed in the headphone level LED display while the
current input source offset level will be shown in the ‘main level/edit’ LED window . A value of “0” indicates
that there is no offset level currently programmed.

Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the value of level offset. Rotate
the encoder in a counter-clockwise motion to decrease the value. Note that these changes are reected in
real-time.

Once you’re satised with the new level offset value, you can select another input source for editing, select a
new function to edit or exit CAL mode.

Exit CAL mode and return to the normal operating state by pressing the ashing CAL switch.
Global Speaker Set Output Level Calibration
There may be times when you’ll want to change the monitor path output levels on a global basis. For
example, the speakers/amps connected to control room outputs #1 may have a different gain structure
than those hooked up to control room outputs #2. The CAL function can be used to enter level offsets
to compensate for this on a global basis. The relative range of calibration is +/- 10dB in 0.5dB steps.
Here’s the procedure:

Enter CAL mode by pressing the CAL switch. The switch LED will begin to ash, indicating that you’re now in
calibration mode. All other switch LEDs on the remote control unit will be unlit. If you inadvertently entered
CAL mode, simply press the CAL switch again. You’ll be returned to the normal operating state of the m906
and the CAL switch LED will extinguish.

Press the SPKR SEL switch. The last speaker output set that was active
prior to entering CAL mode will be indicated by ashing its LED and will
named on the rst line of the LCD (screenshot 8). If you’d like to calibrate
the other speaker set output, simply press the SPKR SEL switch again to
cycle to that choice.

“CAL” will be displayed in the headphone level LED display while the current speaker set output offset level
will be shown in the ‘main level/edit’ LED window. A value of “0” indicates that there is no offset level currently
programmed.

Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the value of level offset. Rotate
the encoder in a counter-clockwise motion to decrease the value.

Once you’re satised with the new offset value, you can select another speaker output set for editing by
pressing the SPKR SEL switch again, select a new function to edit or exit CAL mode.

Exit CAL mode and return to the normal operating state by pressing the ashing CAL switch.
Calibrating Individual Monitor Output Channels
As outlined above, you can edit output levels on a global basis for each speaker set output on the
m906. The system also provides the ability to edit each channel’s level setting within each of the
speaker output sets. As an example, you may have a 5.1 congured set of amps/speakers currently
being driven from speaker output set #2 that includes surround monitors that have a different input
