New ALP-X Card Support 128 I/O Channels

Why It Matters

The 128‑channel offering lets broadcasters and mission‑critical users consolidate hardware, cut costs, and improve reliability, accelerating the shift to fully IP‑based audio infrastructures.

Key Takeaways

• ALP‑AES67‑128 doubles I/O to 128 channels.
• Supports AES67, Ravenna, ST2110‑30, ST2022‑7 standards.
• Redundancy via ST2022‑7 Class D or switch mode.
• Three PCIe form factors fit PCs and servers.
• Windows and Linux drivers enable multi‑card, multi‑client use.

Pulse Analysis

The surge in IP‑based audio workflows has pushed manufacturers to deliver ever‑higher channel densities. Digigram’s latest ALP‑AES67‑128 card arrives at a time when broadcasters, post‑production houses, and mission‑critical facilities are consolidating dozens of audio streams onto a single network backbone. By extending its proven ALP‑X platform from 64 to 128 simultaneous I/O paths, the company addresses a clear gap in the market for scalable, low‑latency solutions that remain fully compliant with AES67, Ravenna, SMPTE ST2110‑30 and ST2022‑7. This leap in capacity enables studios to double their routing flexibility without adding extra chassis.

Beyond raw channel count, the ALP‑AES67‑128 emphasizes network resilience. The card can be equipped with two or four 10‑GbE ports and operates in ST2022‑7 Class D redundancy or simple switch mode, guaranteeing uninterrupted audio even if a link fails. Its PCIe form factor is offered in low‑profile, double‑width low‑profile, and full‑height variants, ensuring compatibility with everything from compact broadcast racks to enterprise‑grade servers. Native drivers for Windows and Linux expose multi‑card and multi‑client APIs, allowing a single host to manage several cards as a unified audio engine.

For end users, the expanded I/O matrix translates into tangible operational savings. Radio and television stations can replace multiple legacy cards with a single 128‑channel unit, reducing power consumption, rack space, and maintenance overhead. Defense and security installations, which often require redundant, secure audio distribution, benefit from the built‑in out‑of‑band management and AES‑level encryption. As competitors scramble to match Digigram’s channel density, the ALP‑AES67‑128 sets a new benchmark that could accelerate the industry’s shift toward fully networked, high‑definition audio production.
