Audio professionals rely on the Red 1 mic pre to produce the required quality of signal to tape. The Red 1 provides 4 perfectly matched channels of the excellent microphone preamplification. The design employs the same topology as the acclaimed ISA 215 pre-amps. The result is a phenomenal set of specifications, and probably the most revealing yet forgiving mic amp in history. Extremely low noise and distortion, and delivers a smooth, detailed sound across its very wide bandwidth. Used with high quality ribbon, valve and condenser mics, the Red 1 performs outstanding and the results are astonishing - especially with voice, piano and string instruments. Each channel offers switchable phantom power, phase reverse, an easily-read illuminated VU meter and a handy scribble disc. Mic gain is switched in 6dB steps over a 66dB range, for accurate and precise channel matching. Among the benefits of the unique Focusrite mic amp topology are 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 high gain bandwidth. It also maintains this level of performance with a very wide range of impedance across the inputs. In practice, this makes it perhaps one of the most revealing yet forgiving mic preamp in history.
