DUAL CHANNEL VACUUM TUBE COMPRESSOR

CHAPTER 1

INTRODUCTION

The new S2 Signature Series Dual Channel Tube Compressor is the latest product to emerge from Ivor Drawmer’s high
end designs and offers an ‘all tube - no technical compromise’ circuit using only the highest grade components. The S2
features a host of new creative processing possibilities never before found in an all analogue dynamics package.

BIG- Retains bass frequencies and minimizes undesirable ‘pumping’ by rolling off the detection signal at 75, 125 or
250Hz (user switchable). A fully variable level control allows for the desired amount of Big processing and an in/out
switch provides the option to remove from the signal path for A/B comparison.

BRIGHT- A dynamic high frequency enhancer to keep compressed audio sounding fresh and bright with continuously
variable frequency control (500Hz to 20kHz) and amount of dynamic enhancement.

DRY- Mixes user defined amount of ‘uncompressed’ signal with the compressed signal to create ‘parallel compression
effect’ without the need for external mixing devices.
