The Flex HT is miniDSP’s answer to our customers looking for a pocket sized multichannel processor with HDMI ARC/eARC capabilities . Our team was able to cram a full eight channels of DSP power and a wide range of I/O into the unbelievably compact enclosure.

Eight-channel audio input is via eARC linear PCM over HDMI, or USB Audio. Additional stereo input is supported over SPDIF and TOSLINK optical. Internally, we’ve provided a full suite of miniDSP flexible’s routing and audio processing features: bass management, parametric EQ, crossovers, advanced biquad programming and delay/gain adjustments. In addition, the miniDSP Flex HT is software-upgradable with full-frequency Dirac Live®, the world’s premiere room correction system.

The eight-channel analog RCA outputs feature class-leading low noise and distortion figures. Last but not least, the Flex HT is miniDSP's first product to include WiSA (“Wireless Speaker and Audio Association”) capability. WiSA is designed specifically for low-latency multichannel audio – a perfect match for the Flex HT. The WiSA transmitter we build into each Flex HT can losslessly transmit all eight output channels to WiSA-compatible speakers and subwoofers. After a simple pairing procedure, you're good to go!

The miniDSP Flex HT is the perfect solution for a modern compact processor for home theater and multichannel sound. You just need to let your creativity do the rest!

REMINDER: Please note that the Flex HT does not support bitstream (e.g. Dolby/DTS) decoding. The audio source must be able to output linear PCM (LPCM) for multichannel support over HDMI. 

STOCK UPDATE(19/07/2023): This product is currently in final stages of firmware development to finalize HDMI test. We expect shipments to start in the coming Q3 2023. Thanks for your patience!
