34. BREAK SWITCH
This important “take-a-break” switch quickly mutes
all the microphones and line-level inputs when the band
is between sets. This will prevent protestors or rogue
karaoke singers from storming the stage at the interval.
The monitor send [12] and FX send [13] are not
affected. Check this switch first if you are having trouble
with no sound in the system.
You can still play the stereo RCA tape inputs [17] in
the main stereo mix, and play audio coming in from your
computer via the USB inputs. For example, you could
play a soothing CD while the band is off stage.
35. TAPE LEVEL
This knob controls the input level of signals entering
the tape inputs. It is conveniently located close to the
break switch [34] so all channels may be quickly muted
while bringing up the background music while the band
is taking a break.
36. STEREO GRAPHIC EQ
This 7-band graphic equalizer adjusts the main mix
output. It affects the line-level outputs [3, 14], but not
thetapeoutputs[18],headphones[16],ortheUSB
output [4]. This EQ may be used for the monitor mix
instead of the main mix, if the main mix/mon switch
[37] is engaged. It may also be quickly bypassed using
the EQ in/bypass switch [38].
Each slider adjusts the level of its frequency band,
withupto15dBofboostorcut,andnochangeinlevel
at the center (0 dB) position. The frequency bands are:
125,250,500,1k,2k,4k,and8kHz.
The EQ section comes before the main fader [47]
and meters [33]. As with the channel EQ, just take it
easy. There is a large amount of adjustment, and if you
are not careful, you can upset the delicate balance of
nature. Although it may not seem cool to actually turn
down controls, with EQ it is often your best option. Turn
down the offending frequency range, rather than boost
the wanted range. Use it to reduce the level of some
frequency bands where feedback occurs.
37. MAIN MIX/MON
Use this switch to choose if the stereo graphic
EQ[36]isusedforthestereoleftandrightmain 
mix or if it is used for the monitors. For example,
there may be times when the graphic EQ may be
used wisely in the monitor mix to reduce feedback
in the monitors from nearby microphones.
38. EQ IN/BYPASS
Use this switch to quickly engage or disengage the
stereo graphic EQ. This may be used for quick checks
of EQ settings or to shorten the signal path if not using
the EQ.
39. USB INPUT LEVEL
This control adjusts the signal level of the two chan-
nels coming in from the computer, via the USB port,
relative to the mix of the other channels. Adjust it care-
fully to achieve the desired mix with the other channels.
The USB input from audio software such as Tracktion,
could be individual instrument tracks, a mix of tracks,
or processed tracks.
