FOCUSRITE ISA 428 MkII  4 Channel Mic Pre w/- EQ

The Focusrite ISA 428 MkII incorporates four of Focusrite’s renowned mic pres in a simple-to-operate 2U enclosure, placing four mic preamps, instrument inputs and line ins at your fingertips. The original Focusrite mic pre was designed to suit the microphones of the time; today’s model makes one small change, adding three additional input impedances to the classic ISA110 setting, allowing you to match any microphone, old or new, and access a wide range of sounds, from the character and warmth of a vintage mic to the clear transparency of a modern design. Or you can experiment and bring out just the qualities you want.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.
