On the left of the page, each
Mic/Line In
(
1
to
8
) is represented by a vertical channel strip, with
MIC
/
LINE
input
selection.
When switched to
MIC
, each input provides:
·
Low Cut
filtering, with a choice of roll-off frequencies: 0Hz, 40Hz, 80Hz or 140Hz.
·
48V
phantom power (on/off)
·
-20 dB
Pad
(on/off)
·
Mic input gain
- with a typical range of 79dB (this may vary and shift depending on the given reference
level and headroom).
·
Input meter
, with dBFS levels and a peak hold indicator (in red) - click on the meter to reset the peak
hold value.
When switched to
LINE
, there is no Low Cut filter, 48V or 20dB Pad. So, for line inputs you can control input gain
(with a typical range of 59dB) and input metering only.
On the right of the page, you will see output metering for the four Line Out (1 to 4), and a slider which adjusts the
System Level
. Note that the
System Level
sets the analogue reference level relative to 0dBFS and, therefore,
should be adjusted with care.
