CUE OUTPUT LEVEL *GLOBAL* The relative gain range is from 0 to 100dB where “100” is unity gain and 0 is minus
1.
infinity. Note that this relative range is the same as the m904’s speaker level settings. This provides a convenient
reference for the engineer in setting the CUE output level. The m904 factory default cue level setting is 100.
CUE OFFSET LEFT CHANNEL The trim range for the left channel is +/-10dB in 0.5dB steps
2.
CUE OFFSET RIGHT CHANNEL The trim range for the right channel is +/-10dB in 0.5dB steps
3.
CUE OUTPUT DIM ON TALKBACK The DIM level of the source feeding the CUE output is variable from –0.0dB to
4.
–35dB in 5dB steps. This is engaged only when TALKBACK is enabled.
SPEAKER 3 OFFSET *GLOBAL* Like SPEAKER 1&2, this offset adjusts the overall SPEAKER 3 offset level. The trim

range is +/-10dB in 0.5dB steps.
SPEAKER 3 OFFSET LEFT CHANNEL (screenshot 13) The trim range for the left channel is +/-10dB in 0.5dB steps

SPEAKER 3 OFFSET RIGHT CHANNEL (screenshot 14) The trim range for the right channel is +/-10dB in 0.5dB steps

“CAL” will be displayed in the headphone level LED display while the current speaker output offset level will be

shown in the ‘main level/edit’ LED window.
Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the value of level offset. Rotate the
9.
encoder in a counter-clockwise motion to decrease the value.
For the CUE OUTPUT DIM level adjustment, rotate the ‘main level/edit’ rotary encoder in a counter-clockwise di-
10.
rection to increase the value of DIM attenuation. Rotate the encoder in a clockwise motion to decrease the value.
Exit CAL mode and return to the normal operating state by pressing the flashing CAL switch.

seTTinG The Fixed leVel dac oUTpUTs
The DAC outputs are great to use when you need to make transfers to other machines or for mixing or master-
ing purposes. The LEFT and RIGHT FIXED DAC outputs can be adjusted individually in CAL mode. The absolute
range of calibration is from -96dB to +31.5dB in 0.5dB steps. Note that the m904 factory default setting for the
DAC outputs is 0dB. At this setting, the DAC will 16dBu or +24dBu for 0dBFS depending on the output
amplifier gain jumper settings (contact our factory for more information about these jumbers). Trimming these
values is done as follows:
Enter CAL mode by pressing the CAL switch. The switch LED will begin to flash, indicating that you’re now in cali-
1.
bration mode. The lower line of the LCD reads ‘USE SEL FOR DAC’ (screenshot 15)
Pressing the SEL switch, which is located to the immediate left of the SYSTEM LCD will enter FIXED DAC calibration

(screenshot 16) and the switch LED will begin to flash.

“CAL” will be displayed in the headphone level LED display, while the current DAC output channel level will be

shown in the ‘main level/edit’ LED window. A value of “0.0” indicates the default, non-edited value.
Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the value. Rotate the encoder in a

counter-clockwise motion to decrease the value. The output will change in real-time.
