DISPLAY MODE GLOBAL This parameter sets the speaker output display mode. When standard level is
selected, the speaker level is displayed as a 0-100 range in 0.5dB steps. When reference level is selected,
the speaker level is displayed as a 100dB range in 0.5dB steps based on the ref. level setting (see below).
This parameter is the same for all speaker outputs.
REFERENCE LEVEL GLOBAL This parameter represents the reference level that is displayed (when display
mode = reference level) at the current volume setting. Available range is the current volume setting +/-
100 in 0.5 steps. This parameter is the same for all speaker outputs.
The following is an example of how the reference level may be congured for an 82dBSPL reference
listening level:
• Play and monitor a nominal level noise source.
• Adjust the speaker level until the SPL measurement at the listening position equals 82dBSPL.
• Enter SETUP and navigate to the REF. LEVEL (GLOBAL) parameter and adjust it to 82.
• Navigate to the DISPLAY MODE (GLOBAL) and set the parameter to reference level.
• Exit SETUP. The speaker level will now display 82.0 to correlate with the reference level. An increase or
decrease in the volume setting now corresponds to the listening SPL given a nominal input signal.
At anytime the display mode can be adjusted or changed back to the standard level (0-100) display in
SETUP.
Available setup parameters for each speaker output. Default values are in parenthesis.
SPEAKER 1
speaker name (speaker 1) level oset (0dB) balance (center) sub output (L+R Stereo)
sub oset (0dB) preset level global (0.0) display mode global (standard level) reference level global (0.0)
SPEAKER 2
speaker name (speaker 2) level oset (0dB) balance (center) sub output (L+R Stereo) sub oset (0dB)
preset level global (0.0) display mode global (standard level) reference level global (0.0)
SPEAKER 3
speaker name (speaker 3) level oset (0dB) balance (center) sub output (L+R Stereo) sub oset (0dB)
preset level global (0.0) display mode global (standard level) reference level global (0.0)
VOLUME KNOB GLOBAL This parameter congures the volume knob for standard or coarse/ne opera-
tion. In standard operation the volum e control starts with 0.5dB steps when turned slow and increases
with the rate the volume knob is turned. In coarse/ne mode, the volume control covers the entire range
in a single rotation. Pressing the volume knob down while changing volume enables ne 0.5dB step
changes. This parameter is global for speaker and headphone volume control. The default is ‘standard’.
DIM SETUP
From the setup screen, pressing the dim button enters dim setup mode. Once dim setup mode is active,
pressing the dim button will toggle the dim setting (exactly as it does in normal mode). The dim attenu-
ation level controls how much the speaker/sub outputs attenuate when dim is active. The available dim
range is -35dB to -5dB in 0.5dB steps. The default is -20dB.
SUB / DAC / METER SETUP
The m905 features a multi-funciton SUB/DAC/METER output. From the setup screen, pressing the sub
mute button enters SUB/DAC/METER setup mode. Once this setup mode is active, pressing or holding
the sub-mute / (sub-solo) button functions exactly as it does in normal mode.
