Compressor & Expander; Gate - Tascam SX-1 Reference Manual

Part IV–Mixer Controls
Compressor & Expander
parameters apply to both the Compressor and the
Expander. The only difference is that compression
limits levels above the threshold setting while expan-
sion lowers levels below the threshold setting.
Gain dB Use this fader to adjust the selected chan-
nel's gain (±20 dB) post dynamics processing.
Ratio This fader adjusts the compression ratio (from
1:1 to infinite). For example, with a setting of 4:1, for
every 4 dB of input gain above the threshold, 1 dB of
gain is output.
Threshold dB Use this fader to set the threshold at
which the dynamics processing is active.
Attack ms This fader sets the attack time (0 to 125
ms) for the dynamics processor. Higher values pro-
duce slower attack times, thus allowing more of the
transient through.
Release ms This fader sets the release time (1 to
5000 ms) for the dynamics processor.

BYPASS Press this key to turn dynamics processing
on and off for the selected channel.
The following three parameters are unique to

Gate

the gate algorithm:
Rge dB This slider determines the range of the gate,
which is the amount of attenuation when the gate
closes. The default is –30 dB, but the range is from 0
to –60 dB.
Hold ms Determines the duration that the gate will
remain open without being re-triggered.

MIXER CHANNEL
AUX DYN
Hyst dB Short for Hysteresis, this parameter pro-
vides a way of fine-tuning the clamping action of the
gate. The higher the value, the less "gate chatter",
which often happens with gates as the input signal
remains very close to the gate threshold.
COMP Use this key to select the type of dynamics
processing you want on the selected channel: com-
pressor, expander, or gate. The key's label changes
according to the selection. Use your mouse to click
on the key and bring up the dynamics menu.
MAKEUP Use this key to compensate for level lost
during compression.
SELF This key selects a trigger source for the selected
channel's dynamics processor (the audio signal that
dictates how the dynamics will behave). The selec-
tions are: , , or .
Self Side Both
Self This setting uses the selected channel's audio
to trigger the dynamics processor. It is the default
setting.
Side This setting uses an adjacent channel's (the
channel that would be part of a linked pair—see
"Links" on page 69) audio to trigger the dynamics
processor. This is commonly referred to as a "side-
chain". It is important to note that while the dynam-
ics processor's input is being controlled by the other
channel in this case, the selected channel's audio is
the one affected by the processing.
Both This setting uses the audio from both chan-
nels to trigger the dynamics processor. The effect is
like having a linked pair strapped to one compressor
setting, with the exception that the audio from the
channel providing the "Side" input is not affected.
LIBRARY Use this key to display the Dynamics
Library. For example, If the
rently shows the EQ Library, pressing this key will
override that display and recall the Dynamics Library
instead.
