When you first power-up a new m906 the preamp gain will be set to +31dB, 48V will be set to ‘off’ and
the talkback latch mode will be disabled. Here’s how you can change these settings:
1. Press the CAL switch. The switch LED flashes, which indicates you’re now in CAL mode. All other switch LED’s 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.
2. Press the TALKBACK switch. Once you do this, “CAL” will be displayed in the headphone level LED display and the
‘main level/edit’ LED display will show the current mic amp gain level in dB, Talkback will be engaged, and the
monitors will DIM.
3. To increase the mic amp gain, rotate the main level encoder in a clockwise direction. As you do this, you’ll see the
gain settings change. Preamp gain is adjustable from +10 to +60dB in 3dB steps (except there is no 13dB setting).
Rotate the encoder in a counter-clockwise direction to reduce the gain level.
4. If you’d like to change the state of 48V phantom power, press the TALKBACK switch again. The‘main level/edit’ LED
display now shows the on/off state of 48V for the preamp. Rotating the main level encoder to the right turns 48Von
and rotating to the left turns it off.
5. If you’d like to change the talkback latch mode, press the TALKBACK switch again. The LED display now shows the on/
off state of talkback latch feature. When the circle is on the left of the edit window, the latch feature is disabled and
the talkback button functions in momentary mode. When the circle is on the right side, the talkback button has a
latching operation. Rotate the main level encoder counter-clockwise to disable the latching or clockwise to enable
it.
6. Once you’re satisfied with the new settings, you can select a new function to edit or exit CAL mode.
7. Exit CAL mode and return to the normal operating state by pressing the fl ashing CAL switch.

The two 7-Segment displays on the m906 can be adjusted in brightness to match the working
environment. This is adjusted as follows:
1. Enter CAL mode by pressing the CAL switch. The switch LED will begin to flash, indicating that you’re now in
calibration mode.
2. Pressing the SEL switch, which is located to the below the SYSTEM LCD will enter FIXED DAC calibration and the
switch LED will begin to flash.
3. Press the SEL switch one more time. “ADJUST 7-SEGMENT ***BRIGHTNESS***” will now be displayed.
4. “CAL” will be displayed in the headphone level LED display while the current brightness level is shown in the main
level LED display. The dimmest setting is 1 and the brightest setting is 5.
5. Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the value (1 to 5). Rotate the encoder
in a counter-clockwise motion to decrease the value. The brightness will change in real-time.
6. Once you’re satisfied with the new brightness, you can select a new function to edit or exit. Exit CAL mode and
return to the normal operating state by pressing the flashing CAL switch.
