THORAX Introduction Thorax is a complete recording channel in one box. It consists of a valve microphone preamplifier based on the Sebatron VMP Series, switchable high and low EQ and an optically controlled valve compressor. It is of course free of integrated circuits, being fully discrete Class A with valves run from proper high tension rails. -
Page 4: Preamplifier
THORAX Pre-amplifier The preamplifier stage of Thorax has several input options. A balanced microphone can be connected to either the front or rear XLR input or an unbalanced instrument or line level signal can be connected via the DI Input. - Page 5 Compressor The Thorax Compressor is optical based, but thanks to some unique Sebatron circuitry is faster and has a wider dynamic range than traditional optical compressors. The Compressor Input Insert is a TRS jack on the rear of the unit. The signal path between Preamplifier and Compressor can be interrupted here to use each section independently, or to insert another processor such as a parametric equaliser between them.

Page 6: Meter
Meter The metering section allows you to gain an insight into the internal operations of Thorax. The amount of gain reduction occurring in the compressor can be indicated by switching the Meter Source to GR. The meter should then sit at 0dB and the meter markings will indicate the amount (in dB) of gain reduction. -

THORAX Rear Panel The rear panel of Thorax contains most of the input and outputs and the IEC mains connector. The input voltage range is switchable between 110-120V Voltage and 220-240V. Make sure it is set correctly before you switch the unit on! -
