The m905 utilizes a single rotary pushbutton encoder for control of the speaker and headphone volume
levels, level preset recall and headphone mute. Switching between speaker level and headphone
level control is done by pushing and releasing the volume control knob. The current volume levels are
indicated on the display with the active control being green and the inactive control in light gray. The
volume control is speed sensitive, so the turning the knob at a higher velocity results in faster volume
changes.

WITH SPEAKER CONTROL ACTIVE:
• Clockwise rotation of knob increases volume in 0.5dB increments (max level = 100 in standard display
mode and is user configurable in reference level display mode).
• Counter-clockwise rotation of knob: Decreases the volume in 0.5dB increments (min level = 0).
• Press + hold knob: Recalls global speaker output preset level (configured in SETUP).
WITH HEADPHONE CONTROL ACTIVE:
• Clockwise rotation of knob: Increases volume in 0.5dB increments (max level = 100).
• Counter-clockwise rotation of knob: Decreases the volume in 0.5dB increments (min level = 0).
• Press + Hold knob: If the headphone level is 0.0, press and hold will recall the headphone preset level
(configured in SETUP).
• If the headphone level is greater than 0.0, press and hold will mute the headphone output. This state is
indicated by the headphone mute icon on the display.
SPEAKER OUTPUT SELECTION
The speaker output selection is accomplished using the three illuminated ‘speaker’ push button switch-
es. The active speaker output is indicated by its switch illuminated green, while inactive outputs are not
illuminated. The user dened name (congured in SETUP) is also visible on the display.
SPEAKER 1 Selects the speaker 1 output monitoring path, selects the speaker 1 sub (congured in SETUP)
and mutes speaker 2 and 3
SPEAKER 2 Selects the speaker 2 output monitoring path, selects the speaker 2 sub (congured in SETUP)
and mutes speaker 1 and 3
SPEAKER 3 Selects the speaker 3 output monitoring path, selects the speaker 3 sub (congured in SETUP)
and mutes speaker 1 and 2.
MONITORING OPTION CONTROLS
MUTE / SOLO The multi-function MUTE / (solo) button controls speaker MUTE and monitor path SOLO
features.
Speaker MUTE mutes the signal going to the selected speaker and sub (if assigned) output(s). When
the speaker MUTE is active, the switch is lit solid red and the speaker MUTE icon is shown on the speaker
status display.
