Ref Level
Sets the reference level for the analog outputs 1/2. Choices are +1 dBu, +7 dBu, +13 dBu, +19
dBu, +24 dBu, referenced to digital full scale level (0 dBFS). The RefLevel of the phones outputs
are independently switchable to IEM (+1 dBu), Low Power (+7 dBu) and High Power (+19 dBu).
Auto Ref Level
ON, Off. Default: ON. See chapter 21.3 for details.
Mono
OFF, ON, to Left. Default: OFF. The option to Left sends the sum of left and right channel to the
left output only.
Width
Defines the stereo width. 1.00 equals full stereo, 0.00 mono, -1.00 swapped channels.
M/S-Proc
Aktiviert M/S-Processing. Monoanteile erscheinen auf dem linken Kanal, Stereoanteile rechts.
Crossfeed
OFF, 1, 2, 3, 4, 5. The Bauer stereo to Binaural crossfeed effect emulates speaker playback by
reducing the stereo width in the treble range. Adjustable in five steps.
DA Filter
Short Delay Sharp, Short Delay Slow, Sharp, Slow, SD LD (Short Delay Low Dispersion), Brick-
wall, NOS. The Digital to Analog Converter chip offers several oversampling filters. Default is SD
Sharp, offering the widest and most linear frequency response and lowest latency. SD Slow
causes a small drop in the higher frequency range, but has a less aggressive (less steep) filter.
Sharp and Slow are similar, but have a higher latency. NOS is the filter with the smallest steep-
ness and therefore affecting treble more than the others, but offers the best impulse response.
See the Technical Reference section for graphs illustrating the results in frequency response and
impulse response.
De-Emphasis
Auto, OFF, ON. Default: Auto. For manually de-/activating the DAC's de-emphasis filter. See
chapter 34.5.
Volume
Mirrors the direct volume control via Volume knob or encoder 1. The output level can be set
between -96 dB and +6 dB, mostly in steps of 0.5 dB. The encoders use a special accelerator
algorithm. Turning the knob fast increases the step size. At moderate turning speed the changes
in dB follow the intended volume change. Only at slower turning the finest steps will be used.
Lock Volume
Deactivates volume control via the big VOLUME knob. Volume within the menu still works, and is
used to set the desired output level. Active Lock is indicated in the VOL and Volume screen and
the status bar.
Balance
Mirrors the balance control in the VOL screen. Adjustable from L 100 (left) through <C> (center)
to R100 (right).A quick turn jumps from L or R to <C> and vice versa.
Mute
Mutes the output. Can also be controlled via the VOL screen and Remap Function Keys.
Dim
Reduces the volume of the current output by 20 dB. Also available via the Remap Function Keys.
Adjusting Volume to a higher value deactivates Dim immediately, lowering Volume will set the
Dim value as new Volume value.
