THE STANDARD OUTPUT MODULE
The FORUM Group Output Module supplies the Group Output
signal, and also two return inputs, for use with multitrack tape
machines, or external effects devices. The group outputs are
electronically balanced, but may also be transformer balanced as a
cost-option.
Return A is permanently routed to the stereo mix. Return B can be
routed to the stereo mix, or to the sub-group bus. The group output
can be routed to the return B input. The Return B section can be
used either in ìPAî mode, or ìRecordingî mode. These modes are
described under the appropriate section below. An Insert point is
provided in the group signal path, which allows the connection of
external processing devices such as limiter/compressor units. The
Insert connector is on the rear panel of the Group module, and
plugging in the jack automatically breaks the normal signal path
and inserts the external device.
LED METERING
The twenty segment led meter reads the signal present on the
Group output, or the pre-EQ signal present at the return input B.
This latter signal may be the return signal, or the group signal,
depending on the setting of the PA/RECORDING mode switch.
The metering reads post-fader when reading group signals so will
vary with fader position. In TAPE mode, it will read the actual
signal present before the level control of the return section PB). An
internal link allows the meter to display with average PVU) or peak
PPPM) characteristics.
