1 Input Channel Section (page 15)
Two types of input channels are provided – mono and
stereo – but the basic block structure of each is the same.
After going through phantom power, input gain, phase
reversal, and high-pass filter stages, the audio signal
passes through a 4-band equalizer before it reaches the
channel fader. External processing gear can be inserted
into the channel signal path either before or after the EQ
block. The post-EQ signal can be sent to any or all of 12
stereo aux buses and 8 G/A (group/aux) buses. The audio
signal from the input channel can be assigned to the
stereo L&R bus and/or mono bus. On mono input
channels the signal can also be assigned to the stereo and
mono (center) buses in LCR mode. Up to 12 VCA
groups and 8 mute groups can be set for each channel’s
fader block. Furthermore, the channel on/off status,
master bus assign settings, grouping, and fader settings
can be stored in the console’s scene memory for instant
recall whenever required.
2 Master Output Section (page 26)
The master output section is further subdivided into
stereo aux master, G/A (group/aux) master, and stereo/
mono master sections. Each stereo aux master module
independently controls the signals from two adjacent
stereo aux buses (a total of 12 stereo aux buses).
Depending on the selected G/A bus mode, each G/A
master module can handle the signals from two adjacent
group/aux buses as up to 4 stereo pairs or 8 mono feeds.
The stereo and mono masters are integrated into a single
module, but are independent internally. The stereo and
mono masters receive the signals from the stereo and
mono buses, respectively, and send these signals to the
stereo and mono main outputs. Each master features a
SUB IN input and a [SUM GAIN] control for gain
adjustment. The on/off status of each master, as well as
bus assign and other settings can be stored in the
console’s scene memory.
3 Matrix Send and Master Out Section (page 35)
The matrix section is made up of 4 stereo and 8 mono
matrix mixes. The sends to the matrix mixes are all
derived from the master output section. The matrix input
section is located at the top of the master output section.
The signal from each master can be sent to a matrix bus
by turning the master’s [TO MATRIX] switch on and
using the matrix level controls to apply the signal to the
required matrix bus. The [SUB IN] control located next
to the stereo/mono master [SEND LEVEL] control
adjusts the level of the [MATRIX SUB IN L&R] signal
sent to each matrix bus.
The matrix output section is located to the right of the
matrix input section, and it is here that the final matrix
bus output levels are set. The stereo matrix buses can be
switched to function as mono sends via a utility mode
function, in which case the summed L & R mono signal
is delivered via the L and R outputs. The on/off status of
the matrix outputs can be stored in the console’s scene
memory.
4 VCA Master Section (page 21)
The VCA section can be used to independently control
up to 12 VCA groups (VCA1 ~ VCA12) set up via the
fader blocks of each input channel. The VCA master
faders function as master faders for the corresponding
VCA groups, while the [VCA MUTE] switches mute or
un-mute the corresponding VCA groups. With this
versatile system it is possible to assign a channel to
multiple VCA groups set up for different purposes.
5 Oscillator/Talkback Section (page 38)
From this section the oscillator and talkback signals can
be sent to any of the console’s master and matrix sends.
The [TB/OSC] switches in the master and matrix
sections assign the oscillator and talkback signals to the
corresponding output.
6 Monitor Control Section (page 40)
With two monitor outputs (MONITOR A & B) and
[CUE] switches on each module, any source or
combination of sources can be monitored as required.
Normally the same monitor signal is delivered via the
two main monitor outputs as well as the console’s three
headphone jacks (one at the top of the monitor module,
and two on either side of the front panel). When the
[LCR] switch is engaged the MONITOR A and B
outputs can be used simultaneously for LCR monitoring.
The [SOLO MODE] switches on the meter bridge allow
the module [CUE] switches to be used as solo switches
independently for the console’s input and output sections
(CUE/SOLO function).
