The ISA 428 Pre Pack is the perfect multi-channel front end for any professional DAW. Four classic Rupert Neve-designed, transformer-based preamps with switchable impedance and direct instrument inputs. An optional eight-channel 192kHz A/D converter, preceded by the all new proprietary Soft Limiter circuit, provides the perfect path into your Pro Tools HD system. The benefits of the ISA 428 Pre Pack preamp's topology include superb common-mode rejection, an excellent overload margin and, with its shared gain structure (20dB from the hand-wound transformer and up to 40dB from the amplifier), an extremely low noise floor and super-wide bandwidth (10Hz to 200kHz). This pre amp design is the cornerstone of Focusrite's signature "warm-yet-transparent" sound and the ISA 428 Pre Pack is a point of reference for any discerning audio professional.
