Focusrite ISA 428 MkII

Focusrite’s ISA428 MkII retains all of the primary functions of the original ISA428. You get four hand-wound transformer-based preamps built around the original ISA 110 preamp circuit, housed in a convenient 2U chassis. Each of these incredible preamps features switchable impedance and an impressive 122dB of dynamic range, and each provides you with Focusrite’s highly sought-after warm and transparent sound. You also get the same fantastic DI circuits found on the original ISA428, a favorite of many engineers for the bite they give electric bass. And by omitting the bulky VU meters and soft limiters, and retaining the precise LED metering of the original ISA428, Focusrite reduced the environmental footprint of the ISA428 MkII. They’ve also uncluttered its face and reduced its cost, all without impacting its performance. An optional A/D conversion card gives you up to eight channels of conversion over ADAT lightpipe, so the ISA428 MkII is as easy to integrate into your DAW as ever.
