7. Gain Control - Adjust the gain of the preamp, when Analog Level is set to Mic or Instrument. Gain
Control is hidden when Analog Level is set to +4dBu or -10 dBV line input.
8. Input Settings - Provides options for the various inputs:
● 48V - Enable 48 volt phantom power on the corresponding Analog In channel. Visible only
when Analog Level is set to Mic. Most condenser mics require 48 volt phantom power to
operate.
● Group - Link the Gain Controls for each Analog In channel. Visible only when Analog Level is
set to Mic or Instrument. Gain offsets that exist before grouping channels are preserved.
● Soft Limit - engage Soft Limit on each analog input. Soft Limit is an analog circuit that begins
to attenuate transient peaks at a threshold of -4dBfs, replicating the transient softening of
analog tape.
● Polarity Invert - Invert the polarity of the analog input signal. When a single sound source is
picked up with 2 transducers, inverting the polarity of one transducer results in a fuller sound.
For example, if a drum is captured with a mic on each drumhead, inverting the polarity of one
mic results in a fuller sound with more low end. The same principle applies when capturing an
electric instrument with a miked amp and a direct injection feed.
Playback Channels
1. Playback channels represent the playback signal from your audio software (DAW) outputs. How
the Playback channels are used depends on your monitoring workflow, as described here.
● When your system is configured for software monitoring, set the Speaker and HP outputs to
Playback 1-2 to route DAW outputs directly to hardware outputs.
● When your system is configured for direct monitoring, set the Speaker and HP outputs to
Mixer 1, then balance the Mixer Playback 1-2 input with the direct signal from Analog In 1
and/or 2/
