DUAL/STEREO COMPRESSOR/NOISE GATE CN-220
With the ATTACK switch pressed, the noise gate attack time will be configured in FAST
mode. In this mode, the attack time is very fast, saving the signal rise edge. Therefore, in this
mode the noise gate adjustment is more difficult.
RELEASE TIME CONTROL
The noise gate hold time is defined as the delay in the noise gate closing
(decreasing the input signal gain) when a signal drop the threshold level set up.
The release time begins after the hold time, and ends when the gain reduction
adjusted with the RANGE switch is achieved.
The release time control adjust the noise gate release time between 10 msg and 2 sg,
and at the same time set up a hold time according with the release time adjustment.
RANGE SWITCH
The range switch determines the amount of gain reduction produced in the
program signal when the noise gate is close. With this switch depressed, the program
gain reduction will be 80 dB, and with this switch pressed, the program gain reduction
will be 20 dB.
In most of the applications, it is preferable use the 20 dB range, that although it don't
produce a total gate, and introduce less adverse effects when signals with much noise floor are
processed.
BYPASS SWITCH
When we press this noise gate bypass switch, the noise gate will be disabled and
the controls and switched won’t be operative. The activity LED’s continue working
indicating our set up, but the program signal will pass unchanged through the noise gate.
COMPRESSOR
BAND COMPRESSOR CONTROL AND SWITCH
When the band compressor is active, it’s to say, with the ON switch pressed,
the compressor stops compressing in the whole audio spectrum, in order to only
compress in the selected band. With the ON switch depresses, the compressor
work normally (in the whole audio spectrum).
The band compressor control, allow to configure the selected band from 80
Hz to 10 KHz. Configured the band compressor control between 5 KHz and 10 KHz
works like DE-ESSER, it allow to reduce notably the sibilance effect that takes place with the
treatment of vocals with a great content in high frequencies, mainly with the letter "s."
In band compressor mode, the compression ratio and the threshold adjusts continues
working.
STEREO:
In stereo mode, any of the ON switches will put both compressors in band compressor
mode, however, the band compressor control will be independent in both channels, for that if
you want that the band compressors work symmetrical, both controls will placed at the same
position.
THRESHOLD CONTROL
The threshold control sets the level where compression will begin. The
signals below the level defined at the threshold control will pass unchanged and
