Input Channels © PAD switch
This switch attenuates the signai appiied to the corresponding rear-
panei Hl-Z or LO-Z input by 20dB prior to the head amplifier and input
gain control. The PAD switch effectively increases the range of input
signal levels that can be handled by the mixer, preventing overloading
of the input circuitry when receiving high-level signals.
©GAIN control
This control adjusts the input sensitivity of each input channel between
-60dB (0.775 mV) and -20dB (77.5 mV) when the PAD switch is OFF
(between -40dB and OdB when the PAD switch is ON). This continu­
ously variable gain control allows optimum matching with virtually any
microphone or line source.
© PEAK Indicator
The PEAK indicator LED lights when the post-EQ signal of the corre­
sponding channel's Input reaches a level 3dB below the clipping level
of the channel's circuitry. If the PEAK indicator lights more than only
briefly on high-level tr&nsients it is necessary to decrease the input
sensitivity of the channel using the GAIN control and PAD switch.
Alternatively, if this does not provide sufficient attenuation, reduce the
output level of the source connected to that channel's input.
0 3-band equalizer
The equalizer section provided on each input channel consists of
shelving LOW and HIGH controls, and a peaking MID control with a
MID FREQ control that permits sweeping the midrange center fre­
quency from 350 Hz to 5 kHz.
