RONT PANEL CONTROLS
--::.---- I nput Channels - - ­
o
PAD Switch
This switch attenuates the signal applied to the corresponding rear -panel HI-Z or LO-Z input by
20
dB 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 s ignals_
f)
GAIN Control
This control adjusts the input sensitivity of each input channel between
-60
dB
(0.775
mV)
and
-20
dB
(77.5
mV) when the PAD switch is OFF (between
-40
dB and 0 dB when the PAD
switch is ON). Continuously variable gain control allows optimum matching with virtually any
microphone or line source.
~
CLIP LED Indicator
The CLIP indicator LED lights when the post-EO signal of the corresponding channel's input
reaches a level 3 dB below the clipping level of the channel's circu itry. If the CLIP indicator
lights more than only briefly on high -level transients it is necessary to decrease the input sensi­
tivity of the channel using the GAIN control and PAD switch or, if this does not provide
sufficient attenuation, to reduce the output level of the source connected to that channel's
input.
o
3-band Equalizer
The equalizer section provided on each input channel comprises shelving LOW and HIGH con­
trols
,
and a peaking MID control with a MID FREO control that permits sweeping the midrange
center frequency from
350
Hz to 5 kHz
