ART TCS Twin Compressor System
CONTROLS & INDICATORS
1 Power – Switches the unit’s power on and off.
2
Instrument Input and Level – The front ¼” jack is intended for
instrument level signals and the level control applies from 0 to 30db of
gain to the signal.
When using the front instrument jack, the rear inputs on Channel 1 are
disconnected.
3
Compression Controls (Attack, Release, Threshold, Ratio) –
These four controls control the amount of compression and its’
transient settings. These are continuously active throughout all V3
settings (V3 optimizes ranges for selected application).
4
Noise Reduction Controls (NR Thresh, Shelf, NR Active LED) –
These two controls set the noise reduction characteristics. They are
continuously active throughout all V3 settings. Users can look at the
LED to determine if the current NR is an expander or a gate by viewing
it’s dimming characteristics. When the LED simply turns on and off the
NR is a gate, when it slowly fades in and out it is an expander.
As the NR Thresh is increased, the noise reduction will become more
sensitive to the signals. Thus, more of the signal will be affected by the
NR.
The Shelf control tunes the Noise Reduction detection circuitry such
that it is less sensitive to certain frequencies. When fully counter-
clockwise the noise reduction is most sensitive to lower frequencies,
and when fully clockwise the noise reduction is most sensitive to higher
frequencies.
