Mono and Stereo Operation
In stereo mode, the gain reduction of the left and
right channel is always linked, in order to reduce
stereo image shifting. The gain reduction used will
be calculated from a combination of the two chan-
nels, just as if two hardware CL 1B had been linked
together using a sidechain bus.
Sidechain Bus Select
This knob has two settings:
INTERNAL: Normal mode. The compres-
sion depends on the same ma-
terial as is being compressed.
EXTERNAL: Use an external side chain
(if your hosts supports it) to
control the gain reduction.
In many plug in formats, such as RTAS, VST3 and
AU, it is possible to use an external signal as input
to the detector. This is very common if you for
instance want to compress a bass line using the bass
drum as the trigger to the compressor. In that case,
the bass line will be compressed whenever the bass
drum is hit.
Monitor the Gain Reduction VU Meter when you
set the threshold, since the Input VU Meter will
show the original input signal. Just work with the
Threshold knob until you get enough gain reduc-
tion.
Even if an external side chain signal is present, you will
have to activate the external side chain by setting the
Sidechain Bus Select
to EXTERNAL.
Suggested Applications
Here you will find suggestions on various applica-
tions of the Tube -Tech CL 1B compressor plug in.
They are given as a convenient guide that enables
you to familiarize yourself with the different aspects
of using the compressor. We have not mentioned
specific settings of the Gain and Threshold as they
are dependent on the input levels. Instead we have
specified how much compression in dB we feel is
needed for the various examples.
These examples were taken from the CL 1B hardware
