SKU: FOCISA828 Categories: , Brand:

The eight ISA-series transformer-based microphone preamps feature the same classic microphone preamplifier design as the original ISA110 module from Focusrite’s critically acclaimed FortŽ console (including the original Lundahl L1538 transformer and bespoke zobel network).

The preamps are complemented by eight line inputs, eight line outputs and an optional eight channel 192kHz A-D converter boasting a dynamic range of 122dB. 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 disc recorders and mixing desks.

The microphone input stage additionally includes a variable impedance circuit, allowing the user to switch between four carefully selected input impedance settings. The original ISA110 setting is supplemented by three further impedance settings to either perfectly match the preamp with any microphone, thus maximising level, or to use different settings creatively to shape the sound of the microphone being used.

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 preamp and converter. Vintage design 75 Hz / 18dB per octave high pass filters are also provided on every channel, ensuring unwanted low frequencies are effectively eliminated.

Finally, every channel features a six LED input meter, complete with global precise meter trim. Metering has been designed to utilise the same reference points as DigidesignÕs Pro Tools HDª system and provides clear and accurate input metering, independent of the DAW.
