Mastering Compressor Controls (AM5292)
The 8051 Mastering Compressor is slightly different to the standard 8051 in 2 ways:
q
It has 21 position detented pots for the Trim and Bias controls to aid total mechanical
recall of the unit.
q
It has -1dB switches fitted to the Threshold and Gain Make-Up controls to allow for more
accurate settings, for example, in a mastering application the entire range of the switches
can be turned from 2dB steps into 1dB steps by the selection of the -1dB switches.
