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 1 , 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. In
addition, wireless digital output to WiSA wireless speakers and subwoofers is
provided as standard. An OLED front panel display and volume control/encoder
knob provides easy control. 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!
- 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. Please check your device user manual.
