Group Master Module(A)(module for GROUP MASTER 1 to 4)
As explained earlier in the sections on input channels, signals from the
input channels may be assigned to pairs of groups. This grouping facility
has many uses, for instance multi-track recording, or the ability to adjust
the levels of whole groups of instruments (e.g. a drum kit) simultaneously
without using twelve fingers on the input channel faders. The groups form
the lower part of each "group" module - above the groups is the
matrix, and the AUX SENDs and returns.
[AUX RETURN block]
The AUX RETURN block is found directly above AUX SENDs 1-4 (above groups
1-4).
1. RETURN assign switches (1-2, 3-4, 5-6, 7-8, ST, MONO)
As for single-input modules, except that where a pair of groups or the STEREO
buss are specified, the AUX RETURN's L output goes only to the L STEREO
channel or odd-numbered group, and the AUX RETURN's R output goes only to
the R STEREO channel or even-numbered group.
2.Balance control (BAL/PAN)
Pans between pairs of groups, and/or the stereo buss. The pairs of groups
(or ST) assigned with 1 are treated as stereo pairs, and the position of
the BAL/PAN control determines the proportion of signal sent to the left
(odd numbered) or right (even numbered) group of the pair. The ""
setting (center) sends the signal of this channel equally to both odd- and
even-numbered groups or to the L and R busses of the stereo mix.
The position of this knob has no effect on any output sent to the MONO buss,
or the AUX busses (see 3).
3. RETURN to AUX assign switches (AUX 1, AUX 2, AUX 3, AUX 4)
These controls allow AUX returns to be re-routed directly into AUX SENDs.
This may be useful for cascading effects units, for example.
They work in exactly the same way as the RETURN assign switches 1 except
that AUX SENDs are mono. Therefore they are not affected by the BAL/PAN
control 2.
4. HIGH and LOW equalization controls
The low-noise, low-distortion equalizer offers two bands of EQ, with ?15
dB of gain, in the following ranges:
HIGH: 12 kHz shelving type.
LOW: 80 Hz shelving type.
Response is flat in the center "" position.
5. AUX RETURN LEVEL control
This control adjusts the level of the appropriate AUX RETURN signal which
is fed to the selected buss(es). Nominal send level of 0dB is at the ""
mark on the control.
6. ON/EDIT switch, and ON and CHECK indicators
As for single-input modules
7. AUX RETURN CUE switch
As for the AUX SEND CUE switch.
[AUX SEND block]
8. LEVEL controls (master AUX SEND controls)
These rotary controls control the overall level of the signal
sent to the appropriate AUX SEND connector. They may be used for overall
foldback level, or for adjusting the input level to a signal processor.
Nominal send level of 0dB is at the "" mark on each control.
9. AUX CUE switches
AUX CUE switches These switches add the signal of the appropriate
AUX SEND to the MASTER CUE busses. The pre-fader signal is sent to the MASTER
PFL buss, and the post-fader signal is sent to the MASTER AFL buss. These
busses are not the same as the INPUT CUE buss used by the input channels.
[GROUP block]
As explained earlier in the sections on input channels, signals from the input channels may be assigned to pairs of groups. This grouping facility has many uses, for instance multi-track recording, or the ability to adjust the levels of whole groups of instruments (e.g. a drum kit) simultaneously without using twelve fingers on the input channel faders.
10. Group to mono switch (TO MONO)
When depressed, this switch routes the output of the appropriate
group (post-fader) to the mono buss. As shipped, the routing is pre-onooff
switch, but an internal jumper can be changed to make it post-on/off.
11. Group PAN control
When a group is routed to the stereo buss, this control alters
the levels of the appropriate post-group fader signal sent to the L and
R stereo busses. Turning it fully counterclockwise will send the group entirely
to the L buss, and turning it fully clockwise will send it to the R buss.
The "" position sends the signal equally to the L and R busses.
12. Group to stereo assign switch (TO ST)
When depressed, this switch will route the output of the appropriate
group (post-fader) to the stereo buss. The same internal jumper as used
for the TO MONO switch affects TO ST, making it pre- or post-on/off switch.
13. ON/EDIT switch, and ON and CHECK indicators
The ON/EDIT switch is a momentary (non-latching) type that controls
output from the group. Pressing it turns the ON indicator on and off alternately.
While the ON indicator is illuminated, signals from this group are sent
to the specified group output, and meter. When the indicator is off, signals
from the group are completely muted, so the control may be used for minimizing
noise in quiet passages, for groups which are not needed at the time.
The CHECK indicator is for use with the scene memories, and allows the user
to see beforehand what the condition of the group will be after a new scene
is recalled. In critical performance situations, this feature is likely
to avert many potential disasters.
14. Group fader
This fader (of the same specification and calibration as the
input channel faders) controls the level of sound sent to from the groups
to the GROUP OUT connectors, and to the stereo and/or mono buss (if these
have been assigned with the TO ST or TO MONO switches). Nominal level is
0dB.
15. Group CUE switch
This switch will add the signal of the group to the MASTER CUE
busses. The pre-fader signal is sent to the MASTER PFL buss, and the post-fader
signal is sent to the MASTER AFL buss. These busses are not the same as
the INPUT CUE buss used by the input channels.
