5.2 Program Bus Compression
“The BOX” includes two API 527 compressor/limiters in the center section of the
console. These compressors are assigned to the program bus by default for mixing,
but can be routed to the input channels while recording.
To use the compressors while mixing, they need to be assigned to the program bus,
with Compressor 1 assigned to Left side of the program bus and Compressor 2
assigned to the Right. The compressors are located after the PROGRAM SUM INPUT
and pre-insert.
NOTE: Both compressors must be IN, assigned to the program bus, with the link
engaged to apply proper stereo mix compression. When LINK is engaged
the gain reduction control voltage is summed. To assure that gain reduction
is keyed equally by both left and right channels it is essential to set
parameters on both compressors exactly the same.
Refer to section 6.0 Compressors for more information regarding the compressors.
The compressors are assigned to the program bus by default. When PGM-
CHAN is engaged, the compressor is assigned to the selected input channel.
These switches illuminate when engaged. Assignment to the program bus is
accomplished by disengaging the PGM-CHAN switches on the compressor.
The compressor will be bypassed unless the IN switch on the compressor is
engaged. Engaging the IN switch will place the compressor in the signal
path. This switch illuminates when engaged.
Stereo compression during mixing is possible when both compressors are
assigned to the program bus and the LINK switch is engaged. This switch
illuminates when engaged.
