The Focusrite ISA 828 microphone preamp puts eight of Focusrite's original ISA preamps into a compact 2U space, giving you amazing sound quality in a unit that's convenient for both your studio and your wallet. The ISA 828 gives you a variable impedance circuit with several settings, and also includes eight line/four instrument inputs with high and low impedance options. Using 25-pin D-type connectors, this preamp is easy to interface with Pro Tools HD rigs, as well as many other recording systems and mixing consoles.
Microphone preamplifiers lie at the root of the Focusrite family tree. Back in 1985, when Sir George Martin asked console design legend Rupert Neve to design new modules for AIR Studios, the Input Signal Amplifier, or ISA – the mic pre – was the first. That design was the foundation of Focusrite’s benchmark Red range, and its descendants form the ISA series available today.
Key features:
- 8 original Focusrite ISA transformer-based preamps in a single 2U space
