Drawmer S3

The Drawmer S3 Stereo Three Band Optical Compressor incorporates the very latest in Ivor Drawmer designs and the aim from the very beginning was to create a 'no technical compromise' circuit using only the highest grade components.  The S3 forms the basis of a 'Signature Series' and offers previously unattainable control and tonality over each of the three bands - gain control at each stage provides precise spectral balancing.   The signal path consists of high performance input/output transformers, passive components and 10 tubes (8x ECC83 and 2x 12BH7) configured as a fully balanced Class A design.  Because the LDR's (Light Dependent Resistors) in the opto-compressors are temperature sensitive the S3 houses an 'electronic oven' which provides and sustains the optimum LDR operating temperature - thereby maintaining calibration accuracy and improving performance.  A front panel LED indicates temperature status. Large scale VU meters can be switched to 'Peak' mode to show transient information.  Two further VU meter re-scale modes are available (+10dB and +20dB) to accurately display the unit's ability to output levels of up to +30dBm.  The master output section includes controls for both Gain and stereo balance to compensate for source material with a Left/Right imbalance or disproportionate processing.
