MASTER VOL AND “(MAIN OUT)” PHONE
JACK
The phone jack labeled (MAIN OUT) (Figure 6-1)
is a standard quarter-inch stereo headphone jack.
Its output is hard-wired to mirror the XLR main
outs on the rear panel. From the factory, the
MASTER VOL knob above it controls the main
outs and this jack, but MASTER VOL can be
programmed to control any combination of
outputs. See “The Monitor Group” on page 95 for
details. Push the knob once to view the current
volume setting in the LCD display; push it again to
mute the monitor group; push a third time to
return to the previous volume.
☛ Note that if the Monitor Group is
programmed to not include the main outs, the
MASTER VOL knob will no longer control the
volume of the phone jack, either.
Figure 6-2: the phone jacks.
PHONES
From the factory, the PHONES jack (Figure 6-2) is
a discrete output at 44.1/48 kHz, but it can mirror
any other output pair (digital or analog) or serve as
its own independent output. For example, at
88.2/96 kHz, it defaults to mirroring the XLR main
outs. At 176.4/192 kHz, it defaults to mirroring
analog outputs 1-2.
As the primary phone jack, it has its own dedicated
volume knob.
The LCD provides detailed feedback as you turn
the knob (Figure 6-7). To view the current setting
without changing it, just push the knob (without
turning it).
If you would like the (MAIN OUT) phone jack and
the PHONES jack to output the same signal, assign
the PHONES output to mirror the main outs. In
this configuration, both the MASTER VOL and the
PHONES volume knobs control the PHONES
volume.
ANALOG INPUT METERS WITH V-LIMIT™
COMPRESSOR
All eight inputs are equipped with V-Limit™, a
hardware limiter. With the limiter turned off,
signals that hit zero or above will clip (a hard digital
clip). However, with V-Limit enabled, signals can
go as high as +12 dB above zero with no digital
clipping. If the signal then goes above +12 dB, it
will clip, even with V-Limit engaged. In either case,
the clip LED (above +12) will illuminate.
Two input level scales
To accommodate these two scenarios, the eight
analog input meters (Figure 6-3) are labeled with
two different input level scales: from -42 to -1
(when V-Limit is disabled) and -42 to +12 dB
(when V-Limit is engaged).
Figure 6-3: Analog input metering.
For further information about V-Limit, as well as
another feature called Soft Clip, see “Overload
protection” on page 82.
CLIP and HOLD LEDs
The CLIP and HOLD LEDs indicate when clipping
has occurred (either with or without V-Limit). You
can set the amount of time for the HOLD LED. See
“Clip Hold Time” on page 45.
