PHONES

From the factory, the PHONES jack (Figure 6-1) 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.
As explained in the previous section, the LCD
provides detailed feedback as you turn the knob
(Figure 6-4). To view the current setting without
changing it, just push the knob (without turning
it).
If you would like the (MAIN) 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.

METERS AND STATUS LEDS

The meters and LEDs (Figure 6-2) provide
complete status and metering information for all
828mk3 inputs and outputs.
Mic/guitar inputs meters with V-Limit™
compressor
The two ten-segment meters for the mic/guitar
inputs show input levels from -42 to -1 in the first
column of LEDs, plus an additional range in a
second column from zero to +12 dB (plus clip).
Both 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 turned on, 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. For
further information about V-Limit, as well as
another feature called Soft Clip, see "Overload
protection (mic/guitar inputs only)" on page 76.
