The DJ Audio hardware is based around the XS1-U6 multicore microcontroller; an XMOS xCORE-USB™ device with an integrated High Speed USB 2.0 PHY and 6 logical cores delivering 500MIPS of deterministic and responsive processing power. Exploiting the flexible programmability of the xCORE™ architecture, the DJ Audio platform supports USB streaming of 4 input and 4 output audio channels simultaneously - at up to 192kHz. Ideal for mixing two sources and providing main and headphone monitor output feeds. The guaranteed Hardware-Response™ times of xCORE technology always ensure low latency (round trip as low as 3ms), bit perfect audio streaming to and from the USB host. Delivered as source code, the reference software provides a fully featured production ready solution, including support for: Full- and HighSpeed USB operation, USB Audio Class 2.0 & 1.0, MIDI, HID and DFU classes. The XMOS xTIMEcomposer™ Studio development suite and tools then allow for quick and easy software development and customization to add customer specific, product differentiating features.
