FLEX HTX

miniDSP Flex HTx, 400MHz Sharc DSP audio processor, toolbox for subwoofer or multiway speaker tuning, USB/HDMI ARC/EARC, Optional Multichannel Dirac Live license for room correction.

The Flex HTx is the bigger brother of the Flex HT, targeting the need for a multichannel processor with HDMI ARC/eARC capabilities and stellar analog and USB audio capabilities. Within a single rack unit, we packed all the possible connectivity we could fit.

Eight-channel audio input is via analog audio (RCA and TRS), eARC linear PCM over HDMI¹, or USB Audio. Additional digital stereo input is supported over SPDIF and TOSLINK optical. Internally, we’ve provided a full suite of miniDSP’s flexible routing and audio processing features: bass management, parametric EQ, crossovers, advanced biquad programming and delay/gain adjustments. In addition, the miniDSP Flex HTx is software-upgradable with full-frequency Dirac Live®, the world’s premiere room correction system.

Continuing miniDSP’s focus on affordable high-performance audio, the Flex HTx features class-leading low noise and distortion figures. An OLED front panel display and volume control/encoder knob provides easy control.

The miniDSP Flex HTx is the perfect solution for a modern compact processor for home theater and multichannel sound.

REMINDER: Please note that the Flex HTx 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(18/01/2024): All backlog has now shipped. Thanks for all your patience. All orders will now ship within 1-3days from order.

NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team.
