Focusrite Red 1 Quad Microphone Preamplifier

Red 1 Quad Microphone Preamplifier description:

The Focusrite RED 1 Quad Mic Pre. Classic Focusrite Mic Pre transformer-based design, delivers outstanding results with any sound source, but especially voice, piano and string instruments.

The Focusrite RED 1 has four mic pre-amps in a single unit, and 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 easily-read illuminated VU meter, and a handy scribble disc for denoting channels. Mic gain is switched in 6dB steps over a 66dB range, for accurate, precise channel matching and recall. The many benefits of the unique Focusrite mic 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 amplifier) a very low noise floor with the signature wide bandwidth (10Hz to200KHz). It also maintains this level of performance with a very wide range of impedance across the inputs. In practice, this produces a revealing yet forgiving mic pre-amp. The output stages of the Red 1 with its custom transformers, will easily drive very long cable runs - up to several kilometers - without significant loss of quality, making it ideal for remote recordings.
