  • Product Description

    A modern classic with the stamp of Rupert Neve!.

    Now in its second generation, the ISA 428 Mk II 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.


    Front panel instrument inputs

    In addition to the mic inputs, there are four front-panel instrument inputs making the ISA428 Mk II ideal for overdubs in the control room with no need for a DI box. On the back: four line inputs and switchable insert points on each channel to allow routing via external signal processors. There’s also a versatile, vintage design variable high-pass filter to control what’s going on at the bass end. And finally… accurate, 6-LED meters to tell you exactly what’s going down. Optionally available for the ISA428 Mk II is a precision eight-channel A-D converter with 122dB dynamic range and superb jitter performance – ideal for simple interfacing with your DAW.

    Key Features:

    Four ISA series transformer-based preamps

    ISA series mic preamps have been the producers' choice on countless hit records over the last two decades.


    Selectable impedance

    Ideal for mic matching or extended microphone creativity. Settings include the 'Vintage ISA110' setting, providing the original focusrite signature sound. 


    Four front panel instrument inputs

    Instant access on the front fascia - no separate DI box required. 


    Dedicated analogue insert points

    Switchable insert points are featured on every channel, allowing routing (between preamp and output) through additional external processing.


    Accurate LED meters for every channel

    Clear metering designed to catch even the fastest and most elusive of transients.


    Eight-channel optional A-D converter (not included)

    Four additional A-D converter inputs allow eight channels of high quality conversion, with a dynamic range of 122dB and jitter performance below 250 picoseconds.
