Drawmer has launched it’s 1972 Dual Mic/Line and Instrument Mic Preamplifier. Designed around a feature set conceived to enable simple operation, the preamp is intended for both studio and live sound use.
The 1972 Dual Mic/Line and Instrument Mic Preamplifier sports two identical channels of analog pre-amplification in a 1U rack chassis. The Select input source switch has six switch positions to cover the 1/4-inch front panel Instrument input jack for guitars, basses, or electronic keyboards, and five more positions covering separate rear panel XLR input jacks for microphones with or without 48-volt phantom powering or Line level input sources. Other switch positions are provided to match microphones with 200, 600 or 2,400-ohm impedances.
Up to 66 dB of gain in 6dB steps is provided by THAT Corporation technology using a 12-position rotary Gain switch; the switch is detented to aid setting recall. Input levels are monitored on a five LED color-coded meter directly above the Input Gain control, and a compact analog VU meter monitors the final Output level.
Front panel controls continue with a Phase reverse button and the switchable Lo and HiCut filter section that also works as a bandpass filter. The LoCut section is switchable in/out and is a 12db/octave filter that can sweep between 15 Hz to 350 Hz
The unit includes Lift, a low-level, upward expander. When switched in, Lift adds gain to input signals below a level of -30 dB and continues adding gain until a level of 0dB is reached. Additionally, starting at -30 dB, the amount of added gain is gradually reduced as the average level approaches 0 dB
Also onboard is Shape, comprised of two separate, fixed-frequency tilt or see-saw equalizers, both centered at 500 Hz. Low Shape will provide up to a 2.5 dB boost at 40 Hz and, at the same time, attenuates -2.5dB at 10 kHz. Conversely, Hi Shape reduces by 2.5 dB at 40 Hz and, at the same time, boosts up to 2.5 dB at 10 kHz.
