0 LOW-EQ controls
These are used to control the sound quality in the low
range of each channel. The low frequency of 100Hz can
be controlled across a range of ±15dB between the left¬
most and rightmost settings, and a flat response can be
yielded at the center (0) position.
© HIGH-EQ controls
These are used to control the sound quality in the high
range of each channel. The high frequency of 10kHz can
be controlled across a range of ±15dB between the left¬
most and rightmost settings, and a flat response can be
yielded at the center (0) position.
O MONITOR 2
PRE FADER & EQ controls
These are the MONITOR 2 channel controls and they
are used to control the signal level which is fed out from
the channel fader pre-stage and sent to the MON OUT 2
jacks. They are also used as holdback (stage monitor)
mixing controls for performers.
© MONITOR 1 (REV/ECHO)
POST FADER & EQ controls
These are the MONITOR 1 channel controls and they
are used to control the signal level which is fed out from
the channel fader and equalizer post-stages and sent to
the reverberation circuit, and the MON OUT 1 and
ECHO SEND jacks.
These controls perform the following roles in accordance
with the intended application.
1. Channel controls for reverberation effect.
2. Channel controls for echo effect.
3. Mixing controls for holdback (stage monitor)
© PAN controls
These controls are used to distribute the input signals of
the channels to the left and right channels, and also to
position the sound images.
© Channels faders
These are used to set the mixing level of the channels
and to attain an overall balance in the volume.
0 AUX IN controls
These are used to control the AUX IN 1 and AUX IN 2
input levels.
© AUX PAN controls
These are used to distribute the AUX 1 and AUX 2
input signals to the left and right channels, and to posi¬
tion the sound images.
0 REVERB/ECHO control
This is used to control the overall output level of the
built-in reverberation unit. When an echo unit has been
connected to the ECHO RETURN input jack, the built-
in reverberation unit is cut off, and the overall output
level of the echo device is controlled.
<D MONITOR 1 master fader
This is used to control the overall level of the signals
which have been already controlled by the MONITOR 1
controls, and to feed the signals out at the MON OUT 1
and Echo send jacks.
(Reverb signals are not controled.)
© MONITOR 2 master fader
This is used to control the overall level of the signals
which have been already controlled by the MOMITOR 2
controls, and to feed the signals out at the MON OUT 2
jack.
© GRAPHIC EQUALIZER
These nine linear controls for each channel, left and
right, vary the frequency response across a ±12dB range
for the frequencies centered on 63Hz, 125Hz, 250Hz,
500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz in accord¬
ance with the intended application or location, and they
thereby vary the sound quality of the whole system. For
instance, they can be used to control levels at frequency
ranges where howl is easily produced, and to control the
sound quality finely by emphasizing some of the fre¬
quency ranges.
© PROGRAM master faders
These are used to control the overall signals which have
been already mixed by the channel faders, and to set the
sound which is ultimately heard through the main
speakers.
© PROGRAM VU meters
These are used to monitor the output levels of the left
and right channels. An output of 42.5W/8f2 is indicated
when the pointers deflect to 0VU and likewise 85W/812
(full power) when the pointers deflect to +3VU.
© PHONES jack
This is the output jack for stereo headphones.
This allows the power amplifier output to be monitored
and the volume is controlled by the PROGRAM master
faders.
© MONITOR VU meter
These are used to monitor the output levels of MONI¬
TOR 1 and MONITOR 2.
