miniDSP launches the MCHStreamer, a multichannel
multiprotocol USB audio interface Now Offers the MCHStreamer for I2S/TDM8/SPDIF/TOSLINK/ADAT/DSD/PDM streaming


HONG KONG, March 12th, 2019 – miniDSP (, a market leading designer and manufacturer of digital signal processing platforms and solutions for a wide range of applications, is proud to announce the launch of the new MCHStreamer. Now available with an MSRP of $115 USD on our webshop, 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. 

“Following the success of the USBStreamer, we engineered the MCHStreamer to become a goto USB audio interface for all multichannel audio formats” explained Tony Rouget, miniDSP CEO. “With support for I2S/SPDIF/TOSLINK/ADAT/TDM8/DSD and PDM formats, the MCHSTreamer is the most versatile audio interface on the market. At its core, an XMOS XCore 200 multi-core chipset  provides a plug&play experience to interface to your 3rd party DAC/MEMS/DSP thanks to our precompiled firmwares.”

With up to 24ch bidirectional audio (TDM8 mode), up to 16 x PDM channels, up to 8ch DSD, up to 8 x ch I2S, the MCHStreamer provide more channels and more audio formats than any other interface. It is even more with its "PDM to I2S Converter mode" where one can easily convert 16 x channels of PDM to interface directly to your 3rd party I2S interface. No more kludging or multiple 3rd party boards with this all-in-one module.
