Compressor
The three controls shown on screen are operated by the first three
encoders on the Monitor Panel.
u
The 1st encoder sets the
Ratio
,
and runs from 1:1 (off) to ∞:1
(Limiting).
Pressing this encoder also swaps between the Compressor and the
Gate/Expander screen (see below).
u
The 2
nd
encoder sets the
Threshold
, and runs from 10 to -20.
By pressing this encoder, you can also set the source of the Sidechain
Input, either sourced from the Channel itself, the EQ on that Channel, or
from the Key Input via the 25-way D-type connector on the Dynamics
cassette.
•
Both leds
OFF
means the signal is coming from the associated
Channel.
•
The
EQ
LED lit means the signal is coming from the associated EQ
output.
•
The
KEY
LED lit means the signal is being taken from an external
trigger.
u
The 3
rd
encoder sets the
Release
time (in seconds) and runs from 0.1
of a second to 4 seconds.
By pressing this encoder, you can also set the Attack time from Slow (3ms
to 30ms, programme controlled) to Fast (3ms for 20dB of gain reduction).
u
The 4
th
encoder is not used to set a variable value, but instead,
pressing it will toggle the compressor between working in
Local Link
(one
press) or
Global Link
(two presses) mode.
Local Link Mode
In Local Link mode, the compressors within an 8 fader section can linked
together to form any size links in any combination, so that all the link
members being compressed are treated as one and compressed
identically.
It is always the loudest signal within this link-group that causes the
compressor to action once the threshold has been reached, regardless of
which signal this actually is.
Creating links will always link that path with the path to it's right.
Links can be any size (from 2 to 8-wide) in any combination.
It is possible to set up a single 8-wide link.
It is not possible to link across different 8-fader sections of the console.
A typical linking example would be channels 1 & 2 linked together, and
channels 4 & 5 linked together to form two link groups.
It would then be possible to include channel 3 to join these links together
to form one complete link, but noting that channel 3 would also be
included in the link group if selected.
To isolate channel 3 it would be necessary to remove the compressor from
- 103 -
If an EQ is being used to be
the Sidechain EQ signal, it will
no longer be available in the
Channel (or Monitor) path.
The EQ pick-off point when
used in this mode will always
be Pre- the Dynamics
processing (but can be Post
Insert if the Inserts are set
Pre- Dynamics).
