170.880UK User Manual
Status Indicators
The master section has 4 status LEDs, which indicate as follows.
POWER When lit, indicates that main power is on
PFL/AFL Pre-Fade or After-Fade Listen is active
LIMIT Amplifier output clip limiter is active
PROTECT Amplifier protection is active.
The amplifier is not operational when in protect mode, which indicates that a fault is detected.
Main Output Level Meters
The main output level meters comprise a pair of volume ladders with 15 LEDs in each.
These normally display the main left and right output levels unless PFL or AFL is active.
When one or more PFL or AFL buttons are pressed in, these ladders will show the output
of that channel (or those channels) directly.
This enables more detailed analysis of the signal level than can be shown by the signal
and clip LEDs alone.
When monitoring any signal levels, it is important to prevent the red LEDs from lighting
for anything longer than a brief flicker. Persistent lighting of the red LEDs indicates
clipping or distortion.
Master Fader Section
The master fader section controls output level for monitors 1 + 2, DSP and main L + R outputs.
62. MUTE Press to mute the relative output(s)
LED indicator lights when muted.
63. PFL / AFL Activates Pre-Fader Listen for monitors
or After-Fader Listen for DSP Effects.
The output of either is routed to the
headphones (33) output and displayed
on the main level meters (see above)
64. Faders Output level slider controls for
Monitors 1 + 2, Effects and Main L + R
Decibel markings (dB) give a reference
to the level setting applied.
