12.2 Main Output 1/2

12.2.1 Settings

Subpage Settings has the same settings as listed for Analog Input, plus:
AD/DA Source
The source of the Main Output 1/2 signal is automatically selected based on the current mode:
Preamp mode: Analog inputs 1/2
USB: Playback channels 1/2
Dig Thru mode: current digital input signal
AD/DA converter: current digital input signal
The entry AD/DA Source is therefore usually grayed out.
Only in AD/DA mode the input signal can be chosen
between Auto, SPDIF, AES and Analog. This allows to
choose between all currently attached digital input signals
for conversion to output 1/2.
Ref Level
Sets the reference level for the analog outputs 1/2. Choices are +4 dBu, +13 dBu, +19 dBu, +24
dBu, referenced to digital full scale level (0 dBFS). This setting is also valid for the front output
PH 1/2, with PH 1/2 having 3 dB higher output level. This way the setting +4 dBu becomes +7
dBu output level, +19 dBu becomes +22 dBu at the phones jack. These two settings are there-
fore identical to Hi-Power Off and On at Phones Output 3/4.
Auto Ref Level
On or Off. See chapter 21.3 for details.
Mono
Off, On, to Left. The latter sends the sum of left and right channel to only the left output.
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.
Crossfeed
Off, 1, 2, 3, 4. The Bauer stereo to Binaural crossfeed effect emulates speaker playback by
reducing the stereo width in the treble range. Adjustable in four steps.
De-Emphasis
Auto, Off, On. For manually activating or de-activating the DAC's de-emphasis filter if required.
See chapter 34.4.
DA Filter
Short Delay Sharp, Short Delay Slow, Sharp, 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. See the Technical Reference section for graphs illus-
trating the results in frequency response and impulse response.
Volume
Mirrors the direct volume control via Volume knob or encoder 1. The output level can be set
between -96 dB and +6 dB, in steps of 0.5 dB. The encoders use a special accelerator algo-
rithm. Turning the knob fast increases the steps. It is therefore very easy to quickly jump from 0
dB to mute by a quick left turn of the encoder knob. At moderate turning speed the changes in
dB follow the intended volume change. Only at slower turning the finest steps will be used.
