Original Red circuit topology and components
Red 1 500 recreates the original Red 1 mic pre, made in England with the original circuitry and components (where commercially available) for that legendary signature sound.
500 Series "Lunchbox" format
For the first time, a Focusrite product is available in this popular portable rack format
Lundahl LL1538 Input Transformer
The original mix transformer used in the original Red modules helps to provide the unique sound and performance of this groundbreaking design.
Carnhill custom output transformer
An important contributor to the sound, the output transformer also allows Red 1 500 to drive long lines, ideal for remote and mobile applications for which the Lunchbox format was originally intended.
Grayhill gold-plated mil-grade gain switch
The switched gain structure of the Red 1 500 means accurate setting and recall, and with a solid, super-reliable, gold-plated selector switch you know you'll get repeatable results.
Suitable for virtually any microphone
With gain from -6 to +60dB in 6dB steps and a carefully chosen input impedance, Red 1 500 is perfect for almost any microphone, be it ribbon, dynamic or condenser.
Backlit VU meter with switchable calibration
The built-in VU meter helps gain accurate, repeatable results, with calibration to ensure your levels are always spot on.
Polarity invert and +48V phantom power
Maximum microphone flexibility in the studio or on location.
