Focusrite ISA428 MkII 4-channel Microphone Preamp

Get four Focusrite microphone preamps at an unbeatable value! The ISA428 MkII preserves all the core features of the original ISA428, offering four hand-wound, transformer-based preamps built around the legendary ISA 110 circuit, all housed in a convenient 2U chassis. Each preamp provides switchable impedance, an impressive 122dB dynamic range, and the warm, transparent sound that Focusrite is renowned for.

The ISA428 MkII also includes the classic DI circuits loved by engineers for electric bass, and by removing the bulky VU meters and soft limiters while keeping precise LED metering, Focusrite reduced the unit’s environmental footprint.
