It has long been recognized that vacuum tubes impart a unique 'warmth' and 'musicality' to an audio signal, but many of the 'classic' tube equalizers fall short of the technical performance demanded in today's digital recording age. Designed to complement the widely acclaimed Drawmer 1960 Mic Pre-Amp Vacuum Tube Compressor, the 1961 Vacuum Tube Equalizer combines low noise circuitry with no fewer than twelve active tube stages to provide two channels of exceptional equalization possessing unique 'personality'. Rather than employ a continuously variable resistor as a means of frequency control, the 1961 utilizes the same rotary 'step' switching system used in vintage designs . This enables the component values for each frequency band to be optimized for uncompromising performance across the entire audio spectrum and also makes setting up more accurate, particularly when treating stereo signals. The design of the 1961 allows the user to control the amount of 'warmth' by deciding how hard to drive the tubes giving a sound as 'clean' as the best discrete solid state designs or as 'hot' as the 'hottest' classic tube designs. The 1961 and 1960 Can be 'interlinked' to provide, in effect, a two channel vacuum tube mixing console, - the perfect mastering or post audio 'sweetening' tool.
