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 level control (8) set to 0. If the clip LED comes
on and remains lit, try reducing the gain.
This active tone control (shelving type: ±15 dB) varies the level of the high frequency range.
This active tone control (peak dip: ±15 dB) varies the level of the mid frequency range.
This active tone control (shelving type: ±15 dB) varies the level of the low frequency range.
Caution: Excessive low frequency boost causes greater power consumption and increases the possibil-
ity of speaker damage.
This adjusts the level of the channel signal added to the effects mix. The effects send signal is taken af-
ter the channel level controls (8) so that adjustments made to the level control will also affect the send
level.
This knob controls the placement of the signal in the stereo eld. When rotated completely counter-
clockwise‚ the signal is present only on the left channel; when rotated completely clockwise‚ only in the
right channel.
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
light,s roughly 3 dB of headroom remains.
