OPERATION
INPUT CHANNEL CONTROLS
(refer to Input Channel Diagram,
Pictorial 1)
Each input channel will accept a sig¬
nal source which may be equalized,
have internal or external effects
added, sent to a monitor system and
sent to the main system for the
audience to hear. The input chan¬
nels have low-impedance mic inputs
(the 3-pin female XLR-type connec¬
tor) and high-impedance mic/line in¬
puts (1/4-inch phone jack). The line
input will accept signals from either
an instrument, high-impedance
microphone, tape deck, drum
machine, or almost any other audio
source.
Always be sure that the
channel fader or master faders are
down before plugging or unplugging
input sources.
1. GAIN control: The GAIN control
adjusts the amplification of the input
stage. This is necessary to accom¬
modate the wide variation in signal
strength presented to the mixer by a
variety of signal sources. The GAIN
control allows the amplification for
each input source to be optimized.
This results in the best
signal-to-
noise ratio and best freedom from
overload distortion.
2. EQ controls: Equalization can be
more simply described as tone con¬
trol. The 200M tone controls are of
the bandpass type; therefore, ex¬
tremely high and low (inaudible) fre¬
quencies are not affected by these
controls.
A. HIGH EQ: 10 kHz Boost/Cut
± 15 dB
This control adjusts the treble
content of the input signal.
B. MID FREQ: 300 Hz-5 kHz
This control sets the center fre¬
quency of the MID EG (the fre¬
quency of the maximum peak or
dip).
C. MID EQ: 300 Hz-5 kHz Boost/Cut ±12 dB
This control adjusts the midrange content of the
input signal.
D. LOW EQ: 90 Hz Boost/Cut ±15 dB
This control adjusts the low-frequency content
of the input signal.
3. FX Send control: The FX Send control determines
the amount of input signal sent to the effects bus. It
is affected by the channel tone controls and the
channel fader.
Since each channel has its own FX control, some
channels can have internal or external effects and
others none. Note that since the internal and exter¬
nal effects share a common send, they will always
have the same sources. Therefore, it is not possible
to have internal effects on one input source and
external effects on another input source at the same
time.
It is possible to have internal and external
effects simultaneously on both input channels, how¬
ever.
The FX control may also be used as a mono send.
This might be useful for a tape recorder send, for
example.
4. MONITOR control: The MONITOR control sets
the level of that input signal in the monitor mix. It is
independent of all input channel controls except the
GAIN control. It is not affected by the channel EQ
controls or the channel fader. Thus, it is not affected
by changes in the main mix.
5. PAN control: The PAN control allows the
channel's input signal to be placed within the stereo
image by assigning more or less of the signal to the
SUB L or SUB R controls.
Turning the PAN control to the left of center moves
the apparent source toward the left speaker, turning
it to the right moves the source to the right speaker.
Centering the control makes the apparent source
centered between the speakers.
If all inputs are
panned center, the result is mono. Proper use of the
PAN control can sometimes help to control acoustic
feedback in a sound reinforcement system by "pan¬
ning" a mic away to the loudspeaker on the opposite
side of the stage.
6. Channel Fader: This control adjusts the channel
level in the main mix. The normal setting for this
control is around the 0-dB mark on the scale.
