Gain
1
This control establishes the nominal operating level for the channel.
The input gain can be adjusted over a wide range to compensate for soft
voices or very loud drums. To maximize the signal-to-noise ratio, the gain
should be set to the proper level, with the channel Fader (12) set to 0. If
the clip LED comes on and remains lit, try reducing the gain.
Hi EQ
2
This active tone control (shelving type: ±15 dB) varies the level of the high
frequency range.
Mid EQ
3
This active tone control (peak dip: ±15 dB) varies the level of the mid
frequency range.
Low EQ
4
This active tone control (shelving type: ±15 dB) varies the level of the low
frequency range.
Caution: Excessive low frequency boost causes greater power consump-
tion and increases the possibility of speaker damage.
MON Send
5
This control adjusts the level of the channel signal sent to the monitor
output. The signal is taken before the channel Fader (12) but after the
channel EQ.
EFX Send
6
This control adjusts the level of the channel signal added to the effects
mix. The effects send signal is taken after the channel Fader (12) so that
adjustments made to the fader will also affect the send level.
Pan
7
This knob controls the placement of the signal in the stereo field. When
rotated completely counterclockwise‚ the signal is present only on the left
channel; when rotated completely clockwise‚ only in the right channel.
This control functions as a balance control to adjust the relative level of
the left and right signals on stereo channels 5/6 and 7/8 on the PV
17/18 and 19/20 on the PV
Clip LED
8
This light normally indicates that the channel signal level is nearing the overload point. The clip indi-
cator circuit monitors the signal at many points in the channel to ensure that it catches all instances
of clipping. It illuminates at +19 dBu and warns that the gain or EQ boost should be reduced. When it
lights, roughly 3 dB of headroom remain.
Level
9
This is the channel output level control. The optimum setting is the 0 (unity gain) position.
