29. CHANNEL FADER
This smooth 60 mm logarithmic, channel output level control (ranges from -97 to +10 dB) sets
the level sent to the L/R, Group 1/2 and Group 3/4 master channels when selected.
The reference setting for this control is “0 dB” — unity gain position.
30. MUTE
This switch mutes all AUX 1-4 sends, L/R, Group 1/2, Group 3/4 and Solo L/R busses for the
channel.
31. MUTE/CLIP RED LED
This red LED normally serves as a clip indicator (2 dB below clipping). It lights continuously
when the Mute button is engaged.
32. SIGNAL/PFL YELLOW LED
This yellow LED normally serves as a signal presence indicator (-15 dB). It lights continuously
when the PFL button is engaged.
33. PFL/SOLO
This switch connects the channel’s pre-fader signal to the PFL mix. At the same time it
switches the headphone and control-room outputs from the Master L/R mix (default) to the
PFL mix. It also connects the PFL signal to the R meter to aid the setting of the input gain
and is not affected by the mute switch position. Depressing any one of the PFL switches
illuminates the corresponding channel PFL yellow-LED and simultaneously activates a
blinking (1 Hz) yellow master LED in the master-PFL section.
34. ASSIGNMENT SWITCHES L/R, (Group 1/2), (Group 3/4)
These switches assign post-fader, post-pan channel signal to the corresponding L/R, Group
1/2 or Group 3/4 bus.
CHANNEL 3 — 8
These channels are identical with Channel 1 and 2 with the following exceptions:
There are no PAD and POLARITY switches.
35. LOW CUT
This is a high pass filter with a corner frequency of 75 Hz. It is used to
filter out rumble, wind noise, and other unwanted, low frequency
components of the signal. (Switchable “on” and “off”.)
36. MID (Hz) EQ
This bandpass (boost/cut) EQ feature is an active tone control. It varies
the mid-frequency level ±15 dB with a fixed center frequency of 800 Hz.
