Focusrite Red 1 Quad Mic Preamplifier in Very Good Condition

The Focusrite Red 1 is a rackmounted 4-channel microphone preamp based on the original Rupert Neve-designed ISA preamp from Focusrite Forte and Studio consoles. It features 66dB of gain, switchable phantom and polarity, and a VU meter.

With four mic pre-amps in a single unit, the Red 1 is ideal for those looking for improved audio performance, as a compact ‘way in’ to digital recording systems, or for location multi-mic recordings. Each channel offers custom-wound Focusrite input transformers, switchable phantom power, phase reverse, an illuminated VU meter, and a handy scribble disc for denoting channels. Mic gain is also switched for accurate, precise channel matching and recall. 

The many benefi ts of the unique Focusrite pre-amp topology include superb common mode rejection, a good overload margin and, with its shared gain structure, (20dB from transformer and up to 40dB from the amplifi er) a very low noise fl oor with the signature wide bandwidth (10Hz to 200KHz). It also maintains this level of performance with a very wide range of impedance across the inputs. In practice, this makes it what one reviewer called, “perhaps the most revealing yet forgiving mic pre-amp in history.”
