Focusrite ISA 828 MkII

Focusrite announces three new products in the ISA range that bring the classic Focusrite sound to Dante Audio-over-IP networks. The eight-channel ISA 828 MkII features the same transformer-based input stage, complete with the Lundahl LL1538 transformer, as its predecessor. New, however, is compatibility with Dante Audio-over-IP networks, facilitated by the optional ISA ADN8 A-D card. Also new is an updated power supply that allows for more efficient power consumption, a reduction in heat generation, and extremely reliable operation. The front panel remains unchanged, with six-step metering on each channel, and front-panel instrument inputs for channels 1-4.

More details from Focusrite (www.focusrite.com):

The Focusrite ISA ADN8 is an optional A-D card for the ISA 828 MkII and ISA 428 MkII. It provides ADAT Optical, AES3 and Dante connectivity at rates up to 24-bit/192kHz. The card offers primary and secondary RJ45 Dante output ports, an AES59-configured DB25 connector for AES3 output, and a pair of TOSLINK connectors for ADAT output. Word Clock I/O on BNC connectors allows synchronization with many external devices.   

The final new introduction is the ISA ADN2, an optional two-channel 24-bit/192kHz A-D card that provides high-quality analogue-to-digital conversion for the ISA One mic preamp and DI. The card offers primary and secondary RJ45 Dante output ports, an XLR connector for AES3 output, a TOSLINK connector for ADAT output and RCA connector for S/PDIF output. Word Clock I/O on BNC connectors allows synchronization with many external devices.    

Pricing is as follows:

ISA 828 MkII: EU (MSRP): €2,352.93 / US (MAP): $2,699.99 / UK (MSRP): £2,041.66

ISA ADN2: EU (MSRP): €403.35 / US (MAP): $499.99 / UK (MSRP): £349.99
