Focusrite Red 2 stereo EQ. 

The Red 2 hardware is derived from the ISA 110 equalizer circuits, initially designed for the sidecar upgrade of the Neve console at Sir George Martin’s Air Studios, London. Its flexible 6-band configuration with high and low-pass filters is powerful and responsive. Distinguished by its subjectively warm and smooth sound, the Red 2 is extremely versatile and remains highly sought-after.

These transformer-balanced inputs and outputs provide superb isolation, and this classic approach to interfacing contributes to the warm sonic signature of the Focusrite EQ. In fact many owners run their signal paths through the Red 2 to obtain this warmth whether or not they are applying the filters or equalisation.

Derived from the classic ISA 110, the Red 2 equaliser offers switched-frequency high and low-pass filters, switched frequency shelving bands for low and high frequencies, and two fully parametric mid bands with frequency sweep and Q controls.

The shelving high and low bands offer up to 18dB cut and boost from 3.3–18kHz and 33–460Hz respectively, with a constant filter curve shape – unaltered by frequency selection – for smooth, predictable results.

The two fully-parametric, mid bands have considerable overlap in available frequency selection. The low-mid band is sweepable from 40-400Hz or (x3) 120Hz–1.2kHz. The high mid band is sweepable from 600Hz-6kHz or (x3) 1.8kHz-18kHz. The bandwidth (or Q) is continuously variable from 0.3 to 1, allowing a broad or very fine “peaking” or “dipping” curve to be obtained with up to 18db of gain or attenuation.

The high and low-pass filters provide 12db per octave attenuation and are switchable in steps between 36Hz –330Hz and 5.6kHz–22kHz respectively.

They are indispensable for cleaning up signals corrupted by noise at either end of the spectrum.

“You need sweet sounding EQ which the Red 2 has. I use it frequently to brighten or refine vocal sounds in the mix.” Steve Power – Producer for Robbie Williams and other artists

“...offers exemplary quality. Red 2 gave excellent, fast results on a wide range of programme material, with minimum fuss. Whether fattening-up bass, hardening or softening middle, or adding airy top, it was quick and intuitive to use.” Patrick Stapely, Studio Sound

Focusrite Equalisation has a unique design heritage and is renowned for the ease with which outstanding, warm, musical results can be obtained. The Red 2 offers two comprehensive channels of Focusrite EQ with transformer-balanced line level inputs and outputs
