Drawmer 1961 Tube Equalizer 2-Channel pararm., 19" 2HE

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.

Input level. A variable input level of -20dB to +20dB ensures compatibility with a wide range of input source material and enables the user to optimize signal level and drive the tubes 'soft' or 'hot' as required.

High Pass Filter. A variable 12dB/Octave roll-off filter adjustable from - 15Hz to 500Hz section enables the user to remove unwanted low frequencies and sub-sonic noise.

Equalization. Each channel of the 1961 has four main equalizer sections with six carefully chosen overlapping frequencies and a separate tube stage for increased harmonic clarity. Each section also includes variable band width from 0.3 Octave to 3 Octaves and +18dB of Cut and Boost.

BASS frequencies (Hz) 20, 32, 50, 80, 125, 200 LO-MID frequencies (Hz) 100,180, 250, 400, 650,1K HI-MID frequencies (kHz) 0.5, 0.8,1.2, 2.0, 3.2, 5.0 TREBLE frequencies (kHz) 2.5, 4, 6,10,15, 25

Low Pass Filter. A variable 12dB/Octave roll-off filter adjustable from 2.5kHz to 56kHz enables the user to remove high frequency interference or to band limit excessively high levels of high frequencies.

Output Stage. Two additional tube stages in the output section of each channel allow the user to achieve 'soft clipping' by adjusting the input level control whilst visually monitoring the effect upon the 'Soft' and 'O/L' (Overload) LED's.
