Dynamics Section
The Dynamics section comprises a compressor/limiter and an
expander/gate, which use the same gain change element. Both
sections work independently, but can be operational at the
same time, providing sophisticated control of either the
Channel or Monitor signal.
The Dynamics section has three routing buttons associated
with it. Section 4 deals with Dynamics routing in more detail,
but briefly these button function as follows:
MON – switches the Dynamics section into the Monitor path
(Post EQ if the EQ has also been selected to the Monitor path).
CH IN – Switches the Dynamics section into the Channel
audio path PRE EQ.
CH OUT – switches the Dynamics section into the Channel
audio path POST EQ.
If both the CH IN (or CH OUT) and the MON buttons are
selected, then the Dynamics section is switched to the Channel
path but the Dynamics’ side chain is fed from the Monitor
path, post TAPE/GROUP selection. See Section 4 for more
details. This allows the Dynamics to be keyed via either a
multitrack bus or the patch bay.
The Channel Insert Return can also be used as a key input via the Insert KEY switch.
See more on this under Insert Point on Page 3-8.
Compressor/Limiter
RATIO – When turned to 1:1 the Compressor/Limiter section is inactive. Turning the
control clockwise increases the compression ratio to give a true limiter at the fully
clockwise position. The compressor normally has an ‘over-easy’ characteristic. Pulling
the RATIO switch up changes this to peak sensing, and replaces the ’over easy’
characteristic with a hard knee, providing an alternative for some instruments. The PK
LED lights to indicate that this option has been selected.
