ISA 828 MkII

About

ISA 828 MkII is an outboard or monitor controller by Focusrite. It is a hardware unit that houses eight mic preamps, each with Lundahl LL1538 input transformers. Each channel can take a mic or line input, and inputs 1-4 also have front-panel instrument inputs. An optional ISA ADN8 expansion card adds Dante, ADAT and AES3 digital outputs of up to 24-bit/192kHz.
