Flex HTx Features · Floating point SHARC DSP · Flexible and powerful multichan- nel audio processor · Dirac Live 3.x upgrade option · Class-leading analog I/O noise and distortion specifications · Full suite of miniDSP processing · Upgradeable with Dirac Live Hardware · ADI ADSP21489 @400MHz · Multichannel USB audio (8ch) · EARC/ARC HDMI input (8ch PCM) · 8ch AD/DA with audiophile specs · SPDIF/optical stereo inputs · OLED front panel with IR control · 12V trigger output Software Control · Real time live control · Win & Mac compatible · Firmware upgradeable · 4 preset memories · CEC control from TV Applications · Home theater · PC based multichannel audio · Low latency gaming · Subwoofer integration 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. 1. 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.
