Input
This pop-up menu is used to select the input connector and level:
XLR Line +4dBu
– A balanced (pro) line level input is accepted from the
IN-1 and IN-2 (XLR) connectors; gain is fixed: maximum input level is
20 dBu.
XLR Line –10 dBV
– A balanced (consumer) line level input is accepted
from the IN-1 and IN-2 connectors; gain is fixed: maximum input level is
8 dBu.
XLR Mic
– A balanced input is accepted from the
connectors; gain is adjustable between 10 and 75 dB.
Instrument
– An unbalanced input is accepted from the
IN-2 (1/4") connectors; gain is adjustable between 0 and 65 dB. These
inputs are also suitable for -10 dBV line levels.
When Input is set to XLR Mic or Instrument, the following controls are accessible:
Group
– Checking either of these boxes groups the gain setting of both

inputs, so that the hardware encoder or one software encoder controls
both input gains simultaneously. If a gain offset is present between inputs
when Group is checked, this offset is preserved.

Output Level Software Encoder
The level of both line and headphone outputs is controlled simultaneously with this
software encoder, when Level is set to Line out. The attenuation level is indicated
in the value box to the right of the encoder.
