Focusrite ISA-828 8-Channel Mic Pre-amp

Product Description

The Focusrite ISA-828 eight-channel microphone pre-amplifier provides eight original ISA transformer-based pre amps in a single robust 2U chassis. Offers you 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. The preamps feature exactly the same vintage microphone preamplifier design as the original ISA110 module from Focusrite's critically acclaimed Forte console (including the original Lundahl L1538 transformer and bespoke zobel network). 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 ISA828's optional eight-channel 192kHz ADC is the first audio ADC to utilize 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 utilize the same reference points as Digidesign's HD system and provides clear and accurate input metering independent of the DAW.
