13. GROUP AND STEREO BUSS PAN POT (PAN)
In relation with the (10) ~ (12) assign switches, this
control functions as shown in above schematics.
14. MUTE BUTTON (MUTE)
When this button is pressed, the LED above it will
be lit and the signal applied to the INPUT fader (17)
for that channel will be muted. As this function is the
same as if the INPUT fader is quickly moved down
to infinitive, it is convenient when it is desired to
momentarily cut off the sound without moving the
fader position.
As this mute is effective only on the signal immediately
after the INPUT fader (17), it will not affect the PRE
signal connected to the AUX 1, 2 send (8) or the
sound monitored by pressing the PFL button (15).
15. PRE-FADER LISTEN BUTTON (PFL)
When this button is pressed, the LED above it will
be lit and the prefader signal (post equalizer) of this
channel is sent to the PFL buss (in stereo format)
in center perspective. In this operation, MONITOR
selector (26) is by passed, and the PFL buss output
signal (the signal after passing through the PFL/SOLO
level knob (30)) is sent to the MONITOR level knob
(28) and the PHONES level knob (29), and therefore,
you can monitor in center perspective the pre-fader
signal only of the channel whose button is pressed.
Please note, however, that as the signals in solo by
the SOLO buttons (16), (19), (24) and (25) will also
be sent to the PFL buss, these can also be monitored
at the same time.
Also, when at least one of these buttons is pressed,
the L, R section of the meter (32) will indicate the
level of the mixed signal (signal immediately before
the PFL/SOLO level knob (30)) on the PFL buss and
therefore, may be used to confirm the pre-fader level.
This function is effective only on the monitor system
(MONITOR OUT jack 1 - 2 (45), PHONES jack (47),
METER (32)) and has no affect on other outputs.
16. INPUT SOLO BUTTON (SOLO)
When this button is pressed, the LED above it will
be lit and the post fader signal of this channel whose
button is pressed is sent to the PFL buss. For the
same reason as above (15), it will be possible to
monitor the post fader signal only of the channel
whose button is pressed but as the monitored sound
can be confirmed in stereo in the perspective set by
PAN (13), you can adjust EQ (7) without disturbing
the initially planned perspective. Please note, however,
that other signals sent to the PFL buss by other SOLO
buttons and PFL buttons (15), will also be heard.
Also, when at least one of these buttons is pressed,
the L, R section of the meter (32) will indicate the
level of the mixed signal on the PFL buss and
therefore, the post fader level of each channel can
be easily confirmed.
This function is effective only on the monitor system
(MONITOR OUT jacks 1 - 2 (45), PHONES jack
(47), METER (32)) and has no affect on other
outputs.
17. INPUT FADER
Adjusts the sound volume of the signal selected by
GROUP/SUB selector (2). As noise and distortion is
minimum at the scale range of 0±5 (db), it is
recommended to initially set the fader within this
range, then adjust the input level with TRIM (1).
18. GROUP MASTER FADER (1, 2, 3, 4)
These are the individual master faders for the GROUP
buss 1-4. Not only the output levels of GROUP
OUT jacks 1-4 (40) but also the send level to the
GROUP TO STEREO sections (20) and (21) are
adjusted here.
These are normally used to set the send signal levels
to a multitrack recorder.
19. GROUP SOLO BUTTON (SOLO)
When this button is pressed, the LED above it is lit
and, for the same reason as above (16), the output
signal only of the GROUP buss selected can be
monitored in the center perspective. It must be noted
that signals sent to the PFL buss by the SOLO button
and PFL button (15) will also be heard in the monitor.
In addition, if one or more SOLO button is pressed,
the meter (32) L and R section will indicate the mixed
signal on the PFL buss.
This function is effective only on the monitor system
as in above (16).
20. GROUP TO STEREO GAIN KNOB (GAIN 1 - 4)
The knob for adjusting individual levels of the GROUP
buss 1 - 4 output signals (the signal after passing
GROUP master faders 1-4) sent to the STEREO
buss. This is convenient at mixdown when you wish
to group the signals by the GROUP master faders
1 - 4 (18) before sending them to the STEREO
buss.
21. GROUP TO STEREO PAN POT (PAN)
This sets the left/right perspective when sending the
signal from (20) to the STEREO buss. The signal from
(20) and this pan pot is the output from STEREO OUT
jacks 1-2 (43) via the STEREO master fader (22).
22. STEREO MASTER FADER (STEREO MASTER)
The master fader for the STEREO buss. Typically the
master recorder is connected to STEREO OUT jacks
1 and 2 (43) and the send level can be adjusted here.
23. AUX MASTER GAIN KNOB (GAIN)
Adjusts the master level of the AUX buss 1-4.
Levels of the signal output from AUX OUT jacks 1
- 4 can be set by these knobs.
24. AUX SOLO BUTTON (SOLO)
When this button is pressed, the LED above it is lit,
and just as for the GROUP SOLO buttons 1 -4(19),
the AUX buss output signal only of the button pressed
can be monitored at the center perspective. It must
be noted, however, that the signals sent to the PFL
buss by the SOLO buttons and PFL buttons (15) will
also be heard in the monitor.
Also, if even one of these buttons is pressed, the
meter (32) L, R sections will indicate the mixed signal
of the PFL buss and therefore may be used to confirm
the output levels at the AUX OUT jacks 1-4 (39).
This function is effective only on the monitor system
in the same way as in (19).
