Introduction
This guide assists NuPrime system designers, integrators, and users in selecting between AoIP (Audio over IP / AES67) and AES3 (AES/EBU digital) connections for linking H16-series decoders to NuPrime multi-channel devices (using the MCX-800AD as an example). It outlines the trade-offs in scalability, cabling complexity, latency, and expansion potential—from 5.1.2 (8-channel) systems up to 7.1.4 (12-channel) immersive configurations.
System Components
Digital AV Home Theater Processor: H16-AIP or H16-AES
8-Channel Integrated Amp: MCX-800AD
AoIP plugin card for MCX‑800AD: Card‑AoIP‑96A
AES/EBU plugin card for MCX‑800AD: Card‑AES‑96A
AoIP vs AES3 Comparison
| Criteria | AoIP | AES3 (AES/EBU) |
|---|---|---|
| Scalability | High, 16+ channels over a single Ethernet link. | Limited, 2 channels per line or 8 per DB25 connector. |
| Cabling | One ethernet cable carries all channels. | Multiple XLR or DB25 cables required. |
| Distance | Long runs via ethernet/fiber (100m+). | Typically <100m per line. |
| Latency | Low; PTP clock sync required. | Deterministic; embedded clock per line. |
| Flexibility | Routing via software; scalable. | Fixed cabling; limited flexibility. |
| Reliability | Depends on network quality and partition. | Highly stable once connected. |
| Cost/Complexity | Higher setup cost (switches, config). | Simpler hardware setup. |
| Expansion | Seamless for 7.1.4 or larger systems. | Cabling becomes complex beyond 8 channels. |
System Design Scenarios
5.1.2 (8‑Channel) Setup – AES3 Option
- Use H16‑AES connected to MCX‑800AD via AES3 (DB25).
- Ideal for fixed installations with short cable runs.
- Minimal configuration, but limited for future expansion
5.1.2 (8‑Channel) Setup – AoIP Option
- Use H16‑AIP and MCX‑800AD (Card‑AoIP‑96A).
- Single Ethernet link transmits all channels.
- Network‑based routing allows easier reconfiguration.
7.1.4 (12‑Channel) Setup – Recommended AoIP
- Use H16‑AIP as AoIP source, MCX‑800AD units each with Card‑AoIP‑96A.
- Assign channels 1‑8 to the first MCX, 9‑12 to the second.
- Configure routing using Dante Controller or NuPrime Control software.
AoIP Configuration & Best Practices
- Use managed switches supporting PTP and QoS.
- Keep AoIP audio network separate from data traffic.
- Enable redundancy (primary/secondary links) where possible.
- Maintain firmware updates for all AoIP devices.
- Label channels clearly in Dante or NuPrime control software.
Recommendation Summary
For systems starting at 5.1.2 but planning to expand to 7.1.4 or higher, AoIP offers the best balance of scalability, simplicity, and flexibility. AES3 remains a strong option for compact, fixed installations requiring deterministic performance and minimal setup. In NuPrime’s multi‑channel ecosystem, AoIP represents the most future‑proof path for immersive, modular audio architectures—delivering precision, innovation, and seamless integration.
