The Tube Limiter FX Unit in Omnisphere is both a limiter and compressor. It was modeled on the warm sound of the famous Fairchild™ 670 tube limiters of the 1960’s. The Tube Limiter has a slower and smoother response than the other compressors in Omnisphere, that not only works great as a stereo buss compressor/limiter, it also works well for individual instruments. It has a fixed internal compression ratio that matches the character the old Fairchild™ units. The Tube Limiter is an ideal tool for pumping things up in a musically fat way.

LIMIT

Engages and Disengages an additional Brick wall limiter at the output. The compression controls continue to work regardless of whether the brick wall limiter is engaged or not.

THRESHOLD

Sets the audio level at which the unit starts to compress the signal. If the input signal is below the Threshold level, the unit does not apply any compression. Once the level crosses the Threshold, then the compression begins to affect the signal. Range: 0 to -60db

GAIN

A make-up gain stage that adjusts the overall output volume to compensate for compression level reduction. Range 0 to 24 db.

PEAK/RMS

Allows the choice of PEAK Limiting or RMS Compression curves. Peak Limiting detects audio transients that are louder than the set Threshold level and applies compression to control those Peaks to whatever level you’ve set. RMS Compression detects an audio signal’s average level and applies Compression to the overall signal. This helps make the whole audio signal louder. With RMS, there is no specific ceiling for the audio as there is with Peak Limiting.

ATTACK

Adjusts the amount of time that the compressor takes to start compressing once the audio has gone above the Threshold level. Range: 0.1ms to 400ms

RELEASE

Adjusts the amount of time that the compressor takes to stop compressing once the audio has gone under the Threshold level. Range: 10ms to 5000ms.
