CLASSIC EIGHT CHANNEL ISA SERIES PRE-AMPLIFIER

Focusrite’s new ISA828 eight channel microphone pre-amplifier, providing eight original ISA transformer-based pre amps in a single robust 2U chassis, offering the Focusrite signature sound at its lowest cost per channel to date.

The eight ISA-series transformer-based microphone pre amps, with switchable impedance and direct instrument inputs, are complemented by eight line inputs, eight line outputs and an optional eight channel 192kHz ADC. Thanks to its convenient 25 pin D-Type connectors, the ISA828 integrates quickly and seamlessly with ProTools HD, as well as other popular hard disc 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 either perfectly match the pre amp with any microphone, thus maximizing 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 points 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, ideal for eliminating unwanted low frequencies without affecting the rest of the audio signal.

The ISA828’s new optional eight-channel 192kHz ADC is the first audio ADC to utilise Texas Instruments Burr-Brown Pro Audio Amplifiers and Flagship Analog to Digital Converter PCM4220 chips. This cutting-edge technology is encompassed within Focusrite’s own custom analogue circuitry to provide eight channels of unparalleled A/D conversion, delivering a dynamic range of 122dB and jitter at < 250 picoseconds.

Finally, every channel features a six LED input meter, complete with precise meter trim. Metering has been designed to utilise the same reference points as Digidesign’s HD system and provides clear and accurate input metering independent of the DAW.
