Compressor
MODE
Below is the block diagram showing how the compressor works.
Following the input section, the signal is split into the main path
(audio) and the sidechain (control). The main path consists of the
gain control element, followed by the make-up gain section, then
through the limiter and directly to the output.
The sidechain may be equalised by passing it though the EQ section, and this
equalised signal may be monitored by engaging the
LISTEN
function. In this mode,
the sidechain control signal may be equalised to make it more or less sensitive to
certain frequencies. This will in turn affect the threshold of the compressor, making it
compress to a greater or lesser degree depending on the frequency content of the
incoming signal.
However, no matter how the sidechain is equalised, the compression is applied to the
entire main signal – and all frequencies are reduced in gain by the same amount. This
is known as ‘
broadband compression
’. The introduction and use of the sidechain
EQ adds the facility to make this ‘
frequency conscious
’.
