DAC LEVEL 0dBFS  This controls the xed output level of the DAC output when DAC output mode is se-
lected above. The setting is the equivalent balanced analog output level given a 0dB full-scale digital input
level. Available range is -76.0dBu to +24.0dBu in 0.5dB steps. The default is -76.0dBu.
DAC BALANCE  The balance of the DAC output can be adjusted. The available balance range is -10dB to
the left or right in 0.5dB steps. When no balance adjustment is present on the DAC output, the parameter
displays “center”. The default is center.
DAC FILTER  This parameter congures the response of the digital lter used by the DAC when monitor-
ing PCM sources. Fast rollo is the classic linear phase brick-wall lter. It has steep roll-o preventing any
high frquency signals from causing aliasing artifacts. It also causes a con-siderable amount of pre-ringing
and post-ringing at the Nyquist frequency when passing transient information. This lter is great for
looking at converter performance on a test bench where it might be subject to articially high amplitude
signals near 20kHz. Slow rollo is also a linear phase lter but with a much slower roll o. This lter has
much less ringing and overshoot on transient material but can cause alias-ing distortion when presented
with high amplitude high frequency material. The idea here is that in real music there is very little energy
in the high frequency area of the spectrum so aliasing distortion will be negligible. This lter is more musi-
cal than the fast rollo lter. The default is ‘fast rollo’.
METER MODE  This selects the type of meter output when the meter mode is selected above. Available
options are xed meter level and follow speaker. When xed meter level is selected, the output level is
controlled by the meter level parameter below. When follow speaker is selected, the output level follows
the speaker volume level (including any input oset). The default is xed meter level.
METER LEVEL  This controls the xed output level of the meter output when meter output mode and xed
meter level are selected above. The setting is equivalent to the overall system gain. Available range is
-100dB to +18.5 in 0.5dB steps. The default is -100dB.
 CUE OUTPUT SETUP
The m905 features a dedicated cue output. From the setup screen, pressing the MON >CUE button en-
ters cue setup mode. Once this setup mode is active, pressing the mon > cue button functions exactly
as it does in normal mode. The cue output setup parameters are as follows:
OUTPUT LEVEL  This controls the xed output level of the cue output. Available range is 0 – 120 in 0.5dB
steps. The default is 100.
BALANCE  The balance of the cue output can be adjusted. The available balance range is -10dB to the left
or right in 0.5dB steps. When no balance adjustment is present on the cue output, the parameter displays
“center”. The default is center.
DIM ON TALKBACK  Both the internal m905 RCU talkback mic signal or the external talkback mic signal can
be summed with the cue output. When the talkback is active, the source material can be attenuated to
make the talkback easier to hear. The available dim on talkback range is -35dB to 0dB in 0.5dB steps. The
default is -20dB.
 HEADPHONE SETUP
From the setup screen, press and hold the knob to enter headphone setup mode. Headphone setup
parameters are as follows:
BALANCE  The balance of the headphone output can be adjusted. The available balance range is -10dB
to the left or right in 0.5dB steps. When no balance adjustment is present on the headphone output, the
parameter displays “center”. The default is center.
LEVEL OFFSET  The volume level of the headphone output can be calibrated to match other outputs by
