Focusrite Announces the New ISA 828, Featuring Eight ISA Mic-pres with Unrivalled A/D Conversion

The eight ISA-series transformer-based microphone pre amps feature exactly the same vintage microphone pre-amplifier design as the original ISA 110 module from Focusrite's critically acclaimed Forte console (including the original Lundahl L1538 transformer and bespoke zobel network).

The pre-amps are complemented by eight line inputs, four instrument inputs and an optional eight channel 192kHz ADC that out-performs every other converter yet devised. Thanks to its convenient 25 pin D-Type connectors, the ISA828 also integrates quickly and seamlessly with ProTools HD, as well as other popular hard disk recorders and mixing desks.

The microphone input stage includes a variable impedance circuit, allowing the user to switch between four carefully selected input impedance settings. The original ISA 110 setting is supplemented by three further impedance settings to perfectly match or creatively mismatch the pre amp with any microphone collection.

The four front panel instrument inputs also feature high and low impedance options to provide a comprehensive and accessible DI solution.

Insert switches are also featured on every channel, should the need arise to place extra processing between the pre amp and converter.

Vintage design high-pass filters are also provided on every channel.

Focusrite's optional eight-channel 192kHz ADC embodies cutting-edge conversion technology, seated within Focusrite custom analogue circuitry. This provides eight channels of A/D conversion, delivering unparalleled performance; noise at -122dBF and jitter < 250 picoseconds.

Every channel features a six LED input meter, complete with precise meter trim. The meter displays and meter trim calibrations utilize the same reference points as Digidesign's HD system and provide clear and accurate input metering, independent of the DAW.
