ISA Series Transformer-based Pre-amplifier
Encased in a rugged and portable chassis, ISA One offers the classic Focusrite microphone pre-amplifier at its lowest cost to date.
Stereo 192kHz ADC
Cutting-edge conversion technology, incorporating Focusrite analogue circuitry to deliver the best A-D performance in its class (Dynamic range of 119dB).
Flexible Independent D.I. Channel
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 ADC.
Switchable Impedance
Choose one of four carefully selected input impedances, including the original ISA 110 setting, to suit any microphone.
Headphone Output with Volume Control
ISA One can feed either a sum of the two inputs to the headphones output, or an external stereo cue mix (such as a stereo mix feed from an interface) via two TRS Jack inputs on the rear of the unit.
Dedicated Insert Point
Allows you to place extra processing between the pre-amplifi er or D.I. and the optional converter, such as an EQ or compressor.
