HAECOAX4 4K HDMI Audio Embedder: What It Does and How
The HAECOAX4 embeds optical or analog stereo audio into an incoming HDMI 2.0b signal at 18Gbps, in place of the source's audio, set by a rear-panel…
150W Class D Dante Amplifier with DSP — Lo-Z / Hi-Z / 70V/100V
Deliver Dante network audio directly to speakers with a compact, DSP-equipped Class D amplifier. The AUD-DTE-2CHAMP decodes Dante audio and drives Lo-Z (4Ω/8Ω) stereo speakers or Hi-Z (70V/100V) distributed ceiling speaker lines — with balanced analog I/O for legacy integration. Built-in DSP: a six-output audio matrix with two mixers, an 8-band parametric EQ, volume, mute and 0–50ms delay on every output, and 5 presets. Control via RS-232, TCP/IP, Telnet, the Web GUI, or RelayAV, KanexPro’s control app.

The HAECOAX4 embeds optical or analog stereo audio into an incoming HDMI 2.0b signal at 18Gbps, in place of the source's audio, set by a rear-panel…

It decodes Dolby Digital, DTS, DTS-ES 6.1 and PCM up to 192kHz from optical or coaxial input to stereo RCA and 3.5mm headphone outputs at once.

AUD-EXT-ARC150M sends HDMI ARC or optical S/PDIF audio over one CAT5e/6/7 cable: 150m / 495ft at 96kHz, or 90m / 295ft for ARC at 192kHz.
