THORAX

Consisting of a valve mic preamplifier, switchable passive EQ and an optical compressor, Thorax is a channel strip in a class of it’s own.

The all-new Thorax is more than just another channel strip with nice specs. It has some unique Sebatron circuitry and features that will enable you to create new tonal possibilities. The preamplifier section is an expansion of the VMP series circuit with more possibilities in the switchable passive EQ and more valve warmth available via the Colour control. It can be driven ultra clean for transparency or pushed through warm valve tones and into sweet distortion.

The E.Q network operates at the extremities of the audio bandwidth. Upper frequencies can easily be boosted with the ‘ air ‘ selector without sounding harsh or false. This happens before any active circuitry so noise is kept to a minimum. Similarly, frequencies in the lower spectrum are easily contoured by the ‘ deep ‘ control which operates from the 300hz region downwards. The EQ network can be hard bypassed and is also interactive with the ‘ pad ‘ switch to attain an even wider range of colours and textures, many of which are unavailable on other units.



Thorax’s compressor stage uses a unique Sebatron-designed optically driven gain reduction circuit that gives fast, tight control over the dynamics of a signal with a minimum of colouration. It has controls for Threshold, Ratio, Attack and Release, with the attack/release factor switchable over three ranges. Makeup gain is provided by a valve stage with a three position Drive control.


This audio path is complemented by a large, easy to read VU meter that can be switched to indicate preamp or main output level or compressor gain reduction.
