8051 5.1 Compressor User Guide

Mastering Compressor Controls (AM5292)

The 8051 Mastering Compressor is slightly different to the standard 8051 in 2 ways:

￿It has 21 position detented pots for the Trim and Bias controls to aid total mechanical recall of the unit.

￿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.
