TUBE-TECH SMC 2B/M

Stereo Multiband Compressor

Description:

The TUBE-TECH multiband compressor SMC 2B/M is three-band stereo compressor.

The two x-over frequencies are each made with a single RC circuit thereby preserving

optimum summation of the three bands at the output.

The x-over frequency between the low band and the mid band is variable from 60Hz to

300Hz or 240Hz to1200Hz and the x-over frequency between mid band and the high band

is variable from 1,2kHz to 6kHz.

The signals from the three bands are then fed to the three separate side chain circuits,

each common for left and right channel. After processing, the three signals goes to a gain

control, separate for each band and, are thereafter summed and send to the output gain,

controlling the entire output level for all three bands.

Compressor:

The compressors are of the optical device type. It has controls for ratio, threshold, attack

and release.

COMPRESSOR CONTROLS:

RATIO: The ratio control varies the ratio by which the input signal is compressed.

If the ratio selected is 2:1, and the input signal increases 10 dB, the output

signal is only increased by 5 dB.

The ratio control is continuously variable from 1,5:1 to 10:1.

THRESHOLD: The threshold is the point where the compressor begins to respond.

It is defined as the point where the gain is reduced by 1 dB.

The threshold is continuously variable from off to -20 dBU.

ATTACK: The attack control chooses how fast/slow the compressor responds to an

increase in the input signal.

The attack control is continuously variable from 1 to 100 milliseconds.

RELEASE: The release control chooses how fast/slow the compressor responds to a

decrease in the input signal.

The release control is continuously variable from 0,07 to 2,5 seconds.

COMP in/out: This switch controls a relay that bypasses the whole unit.
