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.

Output Mode Selection
⚠ ImportantSelect the correct mode before connecting speakers. Switching modes with speakers connected may cause damage.
| Mode | Configuration | Best For |
|---|---|---|
| Lo-Z Stereo | 2×75W @ 4Ω/8Ω | Passive stereo speakers in a single room or zone |
| Bridged Mono | 1×150W @ 8Ω | Single high-power speaker or subwoofer |
| Hi-Z / 70V/100V | 1×150W | Distributed ceiling speaker systems (multiple speakers on one line) |
Dante Setup
- Connect DANTE RJ45 port to managed switch on Dante VLAN with IGMP snooping + QoS DSCP EF (46)
- Open Dante Controller — AUD-DTE-2CHAMP appears as a discoverable device
- Subscribe the amplifier’s Dante input channels to the desired transmitter (encoder, matrix card, or other Dante source)
- The amplifier’s 2-channel Dante output can be subscribed to by other Dante receivers for zone loop-through; Dante Out CH1 and CH2 each pick their own source in the matrix
DSP & Control
Access via Web GUI (enter device IP) or RS-232/TCP-IP command set:
- 6-output audio matrix: Dante Out CH1/CH2, Line Out L/R and Speaker Out L/R each pick their own source — Dante In CH1 or CH2, Line In L or R, or one of two mixers that blend all four inputs (each −48 to 0dB, or off).
- 8-band parametric EQ on every output: parametric, high/low shelf and low/high pass bands, saved with the 5 presets.
- Per-output delay (0–50ms): Time-align speakers with different distances.
- Input gain: −12 to +12dB on every input, set independently per source (Dante vs analog).
- Volume and mute: per output and master, via Web GUI, RS-232, TCP/IP, Telnet or RelayAV for control system integration.
- Power: auto standby after 0–120 minutes idle, and wake-up over the network; a 5–12V trigger mutes the outputs.
- Presets: 5 complete configurations — recall via RS-232 command or Web GUI.
Typical Applications
| Vertical | Use Case |
|---|---|
| Corporate AV | Route Dante from matrix or encoder → conference room/lobby speakers. No analog cable runs. |
| Education | Drive classroom ceiling zones from Dante. Recall EQ presets per room mode. |
| Hospitality | Hi-Z mode drives 70V ceiling speakers across corridors, dining, meeting rooms from one amp. |
| House of Worship | Bridged mono 150W drives subwoofer or high-power full-range speaker from Dante feed. |
