Focusrite ISAONE Single Channel Preamp/DI (No Flight Case)

ISA series transformer-based preamplifier

Encased in a rugged and portable chassis, ISA One offers the classic Focusrite microphone preamplifier at its lowest cost to date.

ISA One is ideal for both engineers and demanding performers alike, featuring independent gain control, an output for routing to an amp, an independent XLR output on the rear and routing to the optional A-D converter.

Switchable impedance

Choose one of four carefully selected input impedances, including the original ISA110 setting, to suit any microphone.

ISA One can feed either a sum of the two input to the headphones output, or an external stereo cue mix (such as a stereo feed from an interface) via two TRS jack inputs on the rear of the unit.

Allows you to place extra processing between the preamplifier or DI and the optional converter, such as an EQ or compressor.

You can chose to upgrade your unit with an optional digital card that delivers the best A-D performance in its class (dynamic range of 118dB). Alternatively, the ISA One Digital comes with the A-D converter as standard.

The original mic transformer used in the original Red modules helps to provide the unique sound and performance of this groundbreaking design.

ISA One has a moving coil VU meter with variable calibration to suit analogue and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert.
