The Front Panel LCD

CHAPTER 6
OVERVIEW
The front panel LCD displays level meters for all
inputs and outputs (except the phones). On the
1248 and 8M, the LCD also provides horizontal
"long-throw" input metering when adjusting
preamp gain.
On all models, the LCD provides several navigable
menus that provide status information and basic
hardware settings.

LEVEL METERS
In its default state when the unit is first powered on,
the LCD displays level meter activity for all
physical audio inputs and outputs on the device.
Inputs and outputs are labeled by channel number
or left/right stereo configuration, if applicable.
The meters display from -42dBFS to 0dBFS, as
shown by the labels to the left of the LCD display
(Figure 6-1).
8M mic/guitar input meters with V-Limit™
compressor
On the 8M interface, all eight mic/line/instrument
inputs are individually equipped with V-Limit™
(page 18), a hardware limiter that helps prevent
digital clipping from overloaded input signals.
With the limiter turned off, signals that hit 0dBFS
or above will clip (a hard digital clip). However,
with V-Limit turned on, signals can go as high as
+9 dBFS with no distortion due to digital clipping.
If the signal goes above +9 dBFS, it will clip, even
with V-Limit engaged. The small downward meter
to the right of the channel's meter indicates how
much V-Limit is limiting the signal. Lookahead
(page 18) enhances performance by anticipating
peaks, but adds compensated delay (16 samples) to
all inputs. Also see "Soft Clip™" on page 42.
