Optical Compressor - Focusrite VoiceMaster Pro Mode D'emploi

2:1, so that frequency band appears to stay at a more constant volume and does not fall
off in level. The overall effect is that the dynamic range of the selected band (Mid or
High) is compressed to a higher average level without affecting the peaks of the
original signal. Therefore, for example, a vocal can be made louder and set at a more
constant level without aggressively compressing the original signal. The side benefit is
that the two bands can be adjusted independently, to create different tonal mixes of the
original signal, so the user can create subtly enhanced sounds or massively effected
sounds very easily.
- Switches the VINTAGE HARMONICS into the signal path. When
IN (switch)
engaged, the red LED in the switch cap is lit.
MID BAND THRESHOLD (knob)
frequency signals. The amount of boost is controlled by the MID BAND
THRESHOLD knob in relation to the level of the audio passing through the circuit.
A low threshold will result in a larger Mid Frequency Harmonic boost. The circuit
peaks at 3k.
HIGH BAND THRESHOLD (knob)
frequency signals. The amount of boost is controlled by the HIGH BAND
THRESHOLD knob, in relation to the level of the audio passing through the circuit.
A low threshold will result in a larger High Frequency Harmonic boost. The circuit
peaks at 18k.
GAIN BOOST (LED meters)
(right meter) bands' relative boosts, as controlled by the threshold knobs.
- This allows boosting of the mid
- This allows boosting of the high
- This shows the Mid (left meter) and High
- This controls the relative depth of the boost of the harmonic
DEPTH (switch)
frequencies. Engaging the switch (in) causes more obvious harmonic enhancement,
disengaging the switch (out) reduces makes the enhancement more subtle.
- When engaged (in), inserts the VINTAGE
POST COMP (switch)
HARMONICS section after the OPTICAL COMPRESSOR section in the signal
path. When disengaged (out), VINTAGE HARMONICS occur pre-compressor.
Placing the VINTAGE HARMONICS post-compressor means that you are able to
stop the affected harmonics changing the way the compressor responds. If you prefer
to have the VINTAGE HARMONICS affect the way the compressor responds,
disengage the POST COMP switch, placing the VINTAGE HARMONICS section
before the OPTICAL COMPRESSOR.

OPTICAL COMPRESSOR

The OPTICAL COMPRESSOR acts like an automatic volume control, turning
down the volume of a signal if it gets too loud. This reduces variation between loud
and quiet passages, as it automatically reduces the gain when the signal exceeds a given
volume, defined as the threshold. Using the OPTICAL COMPRESSOR helps to
'even out' a performance, stopping a vocal from clipping and/or disappearing in the
mix.
- Switches the OPTICAL COMPRESSOR into the signal path.
IN (switch)
When engaged, the red LED in the switch cap is lit.
