API “The BOX” Operator’s Manual

The 527 compressors in “The BOX” have the following features:
•
Feed-forward or feed-back compression
•
Hard or soft knee compression
•
Patented THRUST ® switch for frequency dependent side chain control
•
Continuously variable detented THRESHOLD control
•
Continuously variable detented ATTACK and RELEASE controls
•
Continuously variable detented RATIO control
•
5-segment gain reduction (GR) meter
•
LINK switch for stereo compression
•
Audio circuit uses the 2520 discrete op-amps
The 527 compressors in “The BOX” are identical to the API 527 modules and the 527 in API’s
“The Channel Strip,” with the exception of the gain reduction meter and the a side-chain
input on the TCS. The compressors in “The BOX” do not have a side-chain and the gain
reduction meter has fewer LED segments.
The compressors in “The BOX” can be linked together allowing for stereo compression of the
program bus when mixing or stereo inputs when recording.

6.1 Input Channel Routing
To use the compressors while recording, they need to be assigned to the input
channels. Compressor 1 can be assigned to input channels 1 or 3. Likewise,
Compressor 2 can be assigned to input channels 2 or 4.
Assignments to input channels are accomplished using the two
ASSIGN switches on the compressors. Engaging the PGM-CHAN
switch will move the compressor from the program bus to the input
channels. When PGM-CHAN is engaged, compressor 1 is assigned to
input channel 1 and compressor 2 is assigned to input channel 2 by
default. Engaging CH 3 or CH 4 assigns the compressors to these
channels. These switches illuminate when engaged.
When assigned to an input channel, the compressor will be located
after the preamp and before the equalizer/500 slot and insert by
default. It can be moved to after the equalizer/500 slot and insert by
engaging the COMP POST switch. This switch illuminates when
engaged.
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 recording is possible when both compressors are
assigned to input channels and the LINK switch is engaged. This switch
illuminates when engaged.
