AUD-EARC-8K: eARC Audio Routing, Formats and EDID
The AUD-EARC-8K passes HDMI 2.1 video to the TV and sends audio to soundbar, amp, optical and L/R at once, with no decoding or downmixing.
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: 31-band GEQ, per-output delay, 5 presets. Control via RS-232, LAN, and Web GUI.

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 Dante output (LINE OUT) can also be subscribed to by other Dante receivers for zone loop-through
DSP & Control
Access via Web GUI (enter device IP) or RS-232/TCP-IP command set:
- 31-band GEQ: −10 to +10dB per band. Save to any of 5 presets.
- Per-output delay (0–50ms): Time-align speakers with different distances.
- Input gain: Set independently per source (Dante vs analog).
- Master volume: Adjustable via Web GUI, RS-232, or TCP/IP for control system integration.
- 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. |
| Flex Matrix Pro | Card-level Dante → AUD-DTE-2CHAMP per zone. No analog audio runs from rack to speakers. |
