Source
The source of the analog output signal: Auto, SPDIF coax, Optical, USB, USB (Rec coax), USB
(Rec opt.). Default: Auto.
In Auto Mode any detected SPDIF Signal will have priority over USB playback.
Record SPDIF optical and Record SPDIF Coaxial activate the full duplex operation with USB:
The respective SPDIF signal is clock source and can be recorded via USB. The analog output
signal is the current USB playback, in case the sample rate is identical to the SPDIF input.
Line Output: Ref Level
Sets the reference level for the analog outputs. Choices are -5 dBu, +1 dBu, +7 dBu, +13 dBu
at the RCA output, referenced to digital full scale level (0 dBFS). The levels at the XLR output
are 6 dB higher, +1 dBu, +7 dBu, +13 dBu, +19 dBu.
Phones: Hi-Power
OFF, ON. Default: OFF. Reference level for 0 dBFS is +7 dBu at the output. With Hi-Power on
reference level is 15 dB higher, +22 dBu.
IEM: No choice. The output IEM uses a fixed reference level of -3 dBu.
Auto Ref Level
ON, Off. Default: ON. See chapter 19.3 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
Activates M/S processing. Monaural content is sent to the left, stereo to the right channel.
Polarity (Phase Invert)
Available settings are Off, Both, Left and Right. Inverts the polarity on the corresponding
channel.
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, NOS, SD LD. 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 equal SD Sharp
and SD Slow, with higher latency. NOS has the smallest steepness and therefore affects 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.
Note
: NOS deactivates the option De-Emphasis.
De-Emphasis
Auto, OFF, ON. Default: Auto. For manually de-/activating the DAC's de-emphasis filter. See
chapter 31.2.
