Both mic preamp channels feature custom Class A circuitry, switchable phantom power, phase reverse and an illumated VU meter.
The Red 8 features the same legendary circuitry of the Focusrite Red 1 that has
garnered legendary status with top-flight studios worldwide. Two acclaimed
Focusrite transformer-based mic pres in the sexiest chassis ever created. Internal
engineering insures maximum RF rejection and sonic integrity. This is an industry
Using the same circuit topology as the original ISA mic pre designs, the Red 8 offers
two channels of ultra-high quality Focusrite microphone amplification. Used with high
quality ribbon, valve and condensor mics, the Red 8 obtains outstanding results with
any sound source, especially voice, piano and string instruments.
With two mic pre-amps in a single unit, the Red 8 is ideal for those looking for improved
audio performance, as a compact interface 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 commonmode
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 to 200KHz). It also maintains this level of performance with a very wide range of
impedance across the inputs.
The output stages of the Red 8 with its custom transformers will easily drive very long cable
runs ? up to several yards ? without significant loss of quality, making them ideal for remote
