Focusrite ISA-ONE Professional Mic Preamplifier
The ISA One microphone preamplifier delivers Focusrite's prestigious ISA transformer-based preamp in a rugged and portable chassis, at a groundbreaking price.
ISA One features the classic vintage microphone preamplifier topology from the original ISA110 module, which formed the cornerstone of each channel of Focusrite's legendary Forté console.
The preamp is complemented by a line input and an independent D.I. channel, complete with dedicated gain control, active or passive impedance switch, a TRS Jack output for routing to an amp and an independent XLR output on the rear. This flexible independent D.I. makes the ISA One ideal both for engineers wishing to blend a D.I.’d guitar signal with a mic’d guitar cabinet, and for demanding performers who require a single classic solution for both guitar and vocals.

Optional stereo 192kHz A-D converterYou can choose to upgrade your unit with an optional digital card that delivers the best A-D performance in its class (dynamic range of 118dB).
