Alt PA/Record Output
8
The rotary FADER controls the level to an additional electronically balanced
stereo output which enables the pre or post fade output to be fed to, for example, an
external tape machine. Pre-settable jumpers inside the module source the ALT PA
from either the L&R MIX outputs, or from the MONO MIX output.
9
The default source for the Alt PA/Record output is post the Main Faders, but
can be sourced pre fade by pressing the PRE switch.
10
The stereo output can be switched to mono by pressing the (L-R) SUM switch.
Mix Paths
11
The low noise L, R and MONO summing amplifiers feed the electronically
balanced insert sends at a nominal level of +4<lBu. Separate Insert send and return
jacks are provided. The insert return amps are balanced, and feed the top of the
three main Left, Right and Mono output FADERS . These have+ 1 0dB gain at the
top of their travel. The post-fade signals feed the meters and bargraphs as well as
the electronically balanced output buffers .. The rear panel XLRs are at a nominal"
level of +4dBu. Transformer output balancing is available to special order.
Mute System
12
The MUTE MASTERS 1-8 will mute any channel assigned to the group by
selecting the corresponding channel mute switches.
Channels and Stereo Inputs may
be
assigned to any combination of the eight master
mute busses. When a Channel/Stereo Input is assigned to a mute bus, it is muted
when the corresponding MUTE MASTER is pressed. The MUTE MASTER
switch lights steadily, and the Channel/Stereo CUT switch flashes to indicate a
non-local mute is in operation. The_channel/stereo input may be removed from the
mute bus system by de-selecting the appropriate bus switch.
Output Control
Left and Right monitor outputs are provided to drive control room power
amps/loudspeakers and are fed from a choice of sources determined by the Monitor
Select switches. The chosen source also feeds the headphones output.
13
Headphones connect via a jack socket on the left hand utility panel. This is
paralleled with a jack socket on the rear connector panel. The HEADPHONE
LEVEL control has a gain of +22dB.
14
The Control Room level control has a gain of +lOdB at maximum.
The EXT Talkback feed into the console is summed into the monitor feeds pre the
level controls, and when talkback is activated, dims the selected signal to the
Monitor Outputs and Headphones by 20dB.
