Fredenstein F200 Dual Mic-Pre and Compressor
Compressor:
Like most FET compressors, the Fredenstein F200 features a fixed threshold. The compression
depth is controlled by changing the input gain. Increasing the input gain will cause the compressor
to apply an increased gain reduction. The compressor output level control is used to make up for the
gain reduction. The maximum compressor output gain is +19 dB.
The ATTACK TIME and RELEASE TIME controls define how fast the compressor reacts and how
fast it falls back after the signal is lower than the threshold. The perfect values are depending on the
instrument and the sound you want to achieve.
The COMP RATIO control sets the relationship between input and output level for signals above
the threshold and can be varied from 2:1 to 20:1. A ratio of 20:1 is considered a limiter.
A special feature of the F200 is its integrated output mixer which dramatically boosts the versatility
of the device. If you put the COMP LEVEL fully counter clockwise to zero and the MIC LEVEL
fully clockwise to 10, you are using the F200 as a straight microphone preamplifier. In the opposite
case, putting MIC LEVEL to zero and set COMP LEVEL in the middle position (0 dB gain) or add
make-up gain by turning the knob clockwise up to a maximum of 19 dB.
You can apply a line level signal to the input and activate the PAD , you are in a straight
compressor mode. Or you can use a microphone input signal and you have a mic-pre and
compressor working in series.
As an additional mode, so call dry/wet mixes can be performed. The dry signal (uncompressed) and
the wet signal (compressed) can be mix together in any relationship to achieve special sounds.
