Ch 7-8
STEREO INPUT: Connect any stereo
line-level signal (such an effect
return or electronic instrument)
here. Alternatively, you can
connect two mono line-level
signals.
MONO feature: If only one mono
signal is to be connected,
connect it to the L jack, and
leave the R jack unconnected.
The signal is automatically taken
to both the 7 and 8 channels.
LEVEL: Controls the volume of both
of the inputs simultaneously.
The signal is sent to the
destination selected by the
ASSIGN switch.
ASSIGN: This sends the signal(s) at
the STEREO INPUT to the stereo
mix for recording (L-R) or to the
monitor mix (MON), or turns the
signals OFF (center).
LINE OUT switch: Controls whether
the LINE OUT stereo mix will be
output to the monitor mix, in
stereo (L-R), in mono (MONO) or
not at all (OFF).
EFFECT/CUE switch: Controls
whether the signals sent to
EFFECT 1 or EFFECT 2/CUE or
neither (OFF) will be output to
the monitor mix, or you may
select neither of these for
monitoring (OFF).
LEVEL: Controls the level of the
monitor mix feeding the
MONITOR OUT jacks and
headphones.
EFFECT 2/TAPE CUE switch: This
alters the function of the four
level controls immediately
above the pan controls of
channels 1 through 4.
MASTER fader: This sets the total
output level of the stereo mix.
Ch.1-4
MIC/LINE INPUTS: These are the input jacks for
the mixer channels. Primarily, the 3-contact,
XLR-type connectors are for connection to
balanced microphones, and the 1/4" jacks
are for line-level, unbalanced signal sources
(such as electronic instruments). But you
can also connect lower-level signals (down
to –50 dBV) to these 1/4" jacks and use the
TRIM control to amplify them.
TRIM : Sets how much preamplification will be
added to the MIC/LINE IN jack. Turn to the
right if the signal needs amplification, to the
left if the signal is so loud it is distorting the
mixer electronics.
INPUT : Detemines where the channel signal
comes from.
MIC/LINE (left) brings the mic/line input
into the channel.
OFF (center) shuts off the channel.
TAPE (right) makes tape play back the
channel source.
EQ HIGH : Cuts or boosts treble frequencies.
Shelving point is at 10 kHz.
EQ MID sweep : The upper control sets the
frequency range, centered from 250 Hz to
5 kHz. The lower control cuts or boosts this
frequency range.
EQ LOW : Cuts or boosts bass frequencies.
Shelving point is at 100 Hz.
EFFECT 1 and 2 : These control how much signal
will go to the corresponding EFFECT send
jacks. They get their signal from a point just
after the channel fader.
TAPE CUE : The EFFECT 2 controls can be
switched to act as the TAPE CUE level
controls (by means of the correspondingly
labeled switch) and adjust the playback
level for the musicians in the studio.
PAN : Sets the pan position (left-right balance) of
the channel. Note that the Left Mix can be
recorded on tracks 1 and 3, and the Right
Mix onto tracks 2 and 4.
Channel fader : Sets the volume of the channel
feeding the MASTER fader.

NOTE
DO NOT use both the XLR and 1/4" jacks
in the same channel at one time.
Disconnect one when the other is used.

Ch.5-6
1/4” STEREO INPUTS : Primarily used for
connecting line-level sources. However,
you can also connect lower-level signals
(down to –50 dBV) to these 1/4” jacks
and use the TRIM level to amplify them.
TRIM: Sets how much preamplification will
be added to the MIC/LINE IN jack. Turn
to the right if the signal needs
amplification, to the left if the signal is
so loud it is causing distortion in the
mixer electronics.
INPUT: Determines the source of the channel
signals.
MIC/LINE 1/3/5 (channel 5): Allows you
to choose whether the signal
handled by channel 5 comes from
either of the MIC/LINE inputs of
channel 1, either of the MIC/LINE
inputs of channel 3, or the MIC/LINE
input of channel 5.
MIC/LINE 2/4/6 (channel 6): Allows you
to choose whether the signal
handled by channel 6 comes from
either of the MIC/LINE inputs of
channel 2, either of the MIC/LINE
inputs of channel 4, or the MIC/LINE
input of channel 6.
EQ HIGH: Cuts or boosts treble frequencies.
Shelving point is at 10 kHz.
EQ MID (sweep): The upper control sets the
frequency range, centered from 250 Hz
to 5 kHz. The lower control cuts or
boosts this frequency range.
EQ LOW: Cuts or boosts bass frequencies.
Shelving point is at 100 Hz.
EFFECT 1 and 2: These control how much
signal will go to the corresponding
EFFECT SEND jacks. They get their
signal from a point just after the
channel fader.
TAPE CUE: The EFFECT 2 controls can be
switched to act as the TAPE CUE level
controls (by means of the
correspondingly labeled switch) and
adjust the playback level for the
musicians in the studio.
PAN: Sets the pan position (left-right
balance) of the channel. Note that the
Left Mix can be recorded on tracks 1
and 3, and the Right Mix onto tracks 2
and 4.
Channel fader: Sets the volume of the
channel feeding the MASTER fader.
