MCHStreamer Kit

The MCHStreamer is a multi-channel asynchronous USB interface that supports a myriad of digital I/O formats and leverages miniDSP’s XMOS expertise. . Packaged on a tiny 40x62mm PCB, the MCHStreamer is a perfect fit for OEM/DIY integration or for Research & Development applications.

By loading one of the miniDSP-provided firmware packages, MCHStreamer supports optical TOSLINK, ADAT, S/PDIF (coax), I2S, TDM, DSD and PDM data formats. This USB Audio Class 2 (UAC2) compliant interface truly is the swiss-army knife for audio developers looking to provide an audio interface to PC/MAC/Linux, iOS and Android. It even supports format conversion from 16x PDM MEMS microphone to I2S which makes it a powerful tool for beamforming/voice algorithm development.
