This suppresses frequencies of 80 Hz or lower from the
channel signal at 12 dB/oct (12 decibels per octave)
when it is on. This function is very effective for
removing “touch noise” that occurs when a
microphone is being held, and “blow noise” caused by
breathing.
This varies the high equalizer level between
–15 - +15 dB. The equalizer is a 12 kHz shelving type.

This switches the signal input from the MIC/LINE
connectors to the TAPE IN connectors. Using this
function, sounds, such as those from a multi-track

This controls the input signals from the MIC or LINE
connectors at a suitable level. When connected to the
MIC connector, the input signal level can be controlled
between –10 - –60 dBu, and when connected to the
LINE connector, it can be controlled between +10 –40 dBu. In order to control the input signal at a
suitable level, set the meter to VU operation, press the
PFL button of the channel to be controlled to display
the signal level on the meter. In this state, turn the
LEVEL control to control the signal so that 0VU
display on the meter is lit sometimes.
@¡
This varies the low equalizer level between
–15 dB - +15 dB. The equalizer is a 40 Hz peaking type.
9 AUX 1-2 PAN control
When turned towards the “1”, sound is shifted to the
AUX 1 bus, and when turned in the “2” direction, it is
shifted to the AUX 2 bus. When turned to the
maximum in either direction, the output level is
increased by +3 dB.
!º AUX 1-2 control
This controls the level that is sent to the AUX 1/2
buses. This AUX is a pre-fader (splitting the signal
before the channel fader). It is used to create a separate
balance mix and stereo monitor, as it does not depend
on the position of the channel fader.
This changes the function of the AUX 1/2. When it is
off, the AUX 1-2 PAN control and AUX 1-2 control
operate as normal AUX. When it is on, the input
signals from the TAPE IN connectors (or MIC/LINE
connectors if the TAPE button is turned on) are sent to
the AUX 1/2 buses. Sounds, such as those from a
multi-track recorder that has been connected to the
TAPE connectors, can be monitored through the AUX
1/2 output using this function. (MONO INPUT 1 - 8
only)
!™ AUX 3 and 4 controls
These control the levels that are sent to the
AUX 3 and 4 buses. These AUX’s can switch between
the pre-fader and post fader (splitting the signal after it
has passed through the channel fader) by using the
PRE switch. (Refer to the MASTER section “2 PRE
button”)
!£ AUX 5/7 and 6/8 controls
These control the levels that are output to the
AUX 5/7 and 6/8 buses. These AUX’s are post faders.
As a result, the AUX level changes depending on the
position of the channel fader. This is used when
sending signals to the effector, etc. to be connected
externally.
!¢ AUX 7/8 button
When turned in the “L ODD” direction, sound is
shifted to the MASTER L, GROUP 1, 3, 5 and 7 (odd
channel) buses, and when turned in the “R EVEN”
direction, sound is shifted to the MASTER R, GROUP
2, 4, 6, and 8 (even channel) buses. When turned to the
maximum in either direction, the output level is
increased by +3 dB.
!¶ PFL button
When turned on, the signals before they pass through
the channel fader are routed to the PHONES connector
and the MONITOR OUTPUT connectors, while
displaying the level on the meter. When PFL buttons
for a number of channels are pressed simultaneously, a
mixed signal is routed. In this case, signals from
channels whose AFL button is turned on are not
output.

!¡ MONI button
!§ PAN control
!• PEAK indicator
This is lit up whenever the signal level, after passing
through the equalizer, is within 3 dB of the maximum
level. When this LED is lit, the signal is excessive, and
must be controlled using the LEVEL control. When the
MIC connector is used, change it to the LINE
connector.
!ª Assign buttons
When the L-R button is pressed, the signal is routed to
the MASTER L/R bus, and when the 1/2, 3/4, 5/6 or
7/8 buttons are pressed, the signal is routed to each
group bus.
@º Channel fader
This sets the signal level for the channels.
@¡ DIRECT button
When this button is turned off, the signals from the
GROUP bus are output; and when it is turned on, the
post fader signals from the MONO INPUT channels
1 - 8 are output to the GRP/DIRECT OUT 1 - 8
connectors.
These send the signals to the AUX 5/6 buses when
turned off, and to the AUX 7/8 buses when turned on.
!∞ ON button
* 0 dBu=0.775 V
When turned on, the signals from the channels are

5 AUX 1-2 control
This controls the level to be sent to AUX 1/2 buses. The
signal that has been input to L is routed through the
AUX 1 bus, while the signal that has been input to R is
routed through the AUX 2 bus. This AUX is a prefader (splitting the signal before the channel fader).
Thus, this is used to create a separate balance mix and
stereo monitor, as it does not depend on the position of
the channel fader.
6 AUX 3 and 4 controls
These control the levels to be sent to the AUX 3/4
buses. In this case, the L and R signals are mixed. This

from DAT or MD recorders. The level is controlled by
the 2TR IN level control on the MASTER section.
7 GRP/DIRECT OUT connectors
Phono jacks (Unbalanced, reference level: –10 dBu)
These output each GROUP bus signal. When the
DIRECT button for the MONO INPUT 1 - 8 channels is
turned on, they become direct output connectors that
output post fader signals from each MONO INPUT
channel.

These distribute and output the MASTER OUTPUT L/
R signals. They are connected to DAT or MD recorders,
or equivalent.
!º MONITOR OUT connectors
Phone jacks (Unbalanced, reference level: +4 dBu)
These output the same signals as the PHONES
connector, and signals from any channels whose PFL
or AFL buttons are turned on can be confirmed.
!£ +48 V button
This is the button to supply power (DC +48 V) for
condenser microphones to the MIC connectors of the
MONO INPUT channels 1 - 8. When this button is
turned on, DC +48 V is output to all MIC connectors.
Caution
• Before turning on the +48 V button or after changing the cable
connection, turn down the output fader or the output volume.
• The line equipment must be connected to the LINE input side.
• When a dynamic microphone is used in conjunction with a
microphone that uses +48 V power, the dynamic microphone
may under-perform.
