Description
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.
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 (sold separately).

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.
Eight-channel optional A-D converter — 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.
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 face of the unit - 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.
