Focusrite announce ISA428 MkII

New to Focusrite's renowned ISA range of pro audio hardware is the ISA428 MkII, a premium four-channel mic preamp supporting an optional eight-channel A-D converter. The ISA428 MkII supersedes the existing ISA428 and will be available at a much more affordable price.

The ISA428 MkII features four of Focusrite's classic ISA preamps, originally developed for the legendary Forté console. It supports the same professional eight-channel A-D converter option used with the ISA828. The A-D converter accepts four line inputs in addition to the signals passing through the main channels of the ISA428 MkII, creating eight high-quality digital streams with a superb 122dB dynamic range. Thanks to its convenient 25-pin D-Type connector, the A-D converter option integrates seamlessly with most digital workstations, including Pro Tools HD.

Mirroring the feature set of the original, each ISA428 MkII channel has a variable impedance circuit allowing you to perfectly match the preamp with any microphone, or to use different settings creatively to shape the sound of the microphone. Adjustable high-pass filters as well as phantom power and phase reverse controls are easily accessible on the front panel. 

When designing the ISA428 MkII, the Focusrite R&D team were determined to maintain the pristine sound quality of its predecessor, but introduce it at a new level of affordability. To that end, the exact same analogue circuit board can be found in both the original and MkII derivations of the ISA428.

The ISA428 MkII is expected to be available worldwide in late 2010.
