MiniDSP Flex HTx DSP Processor with eARC - RCA + Balanced

Modern Home Theatre Processing With Dirac Live

The MiniDSP Flex HTx DSP Processor is a compact eight-channel home theatre processor that brings HDMI eARC, full analog and USB connectivity, and optional multichannel Dirac Live room correction into a single rack unit. Feed it from a modern TV or Apple TV over eARC, process every channel, and send eight channels out to your amplifiers on both RCA and balanced connections.

Why You'll Love It

• eARC into a full processing chain. Take multichannel audio straight off a modern TV or streamer over HDMI eARC and run it through bass management, crossovers, EQ and delay before it reaches your amps.
• Multichannel Dirac Live ready. Add the optional Dirac Live 3.x licence for full-range room correction across all eight channels, the same platform used in high-end processors, for a fraction of the price.
• Connect anything, drive anything. Eight channels in over HDMI, USB or analog, and eight channels out on both unbalanced RCA and balanced TRS, so it fits any amplifier or active speaker setup.

Under the Hood

• Serious processing. A 400 MHz Analog Devices SHARC floating-point DSP with the full miniDSP toolbox: routing, bass management, parametric EQ, crossovers and delay.
• Class-leading measurements. Up to 127 dB(A) SNR and -120 dB THD+N, so the processing stays clean and quiet.
• Built for a real system. Rack ears, a 12V trigger to switch your amps on and off, and HDMI CEC so your TV remote handles volume, mute and standby.

CHT Insider Verdict

The Flex HTx is the answer for anyone building a modern, compact home theatre or active speaker system around a TV rather than a traditional AV receiver. Paired with an Apple TV 4K and an eARC television, it becomes a full Dirac Live processor in a single box. Just remember it is a processor, not a decoder, so it is at its best in a streaming-first, PCM setup.

Pro Tip: The Flex HTx does not decode Dolby or DTS, so set your TV or streamer to output PCM rather than bitstream. An Apple TV 4K into an eARC TV is the cleanest way to feed it multichannel audio and get the most from Dirac Live.
