A successor product is now available! Please use TDR Kotelnikov in your new projects.

The TDR Feedback Compressor II is a major design update of its critically acclaimed predecessor. The compressor is dedicated to compressing the highest fidelity stereo program (2-buss), but equally shines in classic mixing tasks.

Most modern compressors analyze the input signal to control gain reduction, using a “feed-forward” topology. TDR Feedback Compressor II, however, analyzes the output. This approach delivers an unobtrusive and highly musical compression characteristic. TDR Feedback Compressor II takes this traditional compression topology to new heights with a highly flexible, yet intuitive control scheme. The compressor has been carefully tuned for intuitive and musical operation for almost every situation.

We want to emphasize the fact that the processor neither tries to emulate any previously available device, nor does it follow popular trends like “virtual analogue”, “circuit modeling” or similar buzz words. This is a proud digital processor, made with an immense amount of love and care.
