Wheatstone Highlights Hitless Failover

Why It Matters

Zero‑downtime audio‑video routing protects broadcasters from on‑air glitches and revenue loss, reinforcing Wheatstone’s leadership in IP‑based production infrastructure.

Key Takeaways

• Hitless failover now available for Blade 4 I/O units
• Dual mix engines synchronize in real time for seamless switchover
• Automatic “heartbeat” detection eliminates packet loss during failures
• Supports SMPTE‑2022‑7 video and AES67 audio standards
• DMX‑12 console adds built‑in Ethernet switch for studio flexibility

Pulse Analysis

Hitless failover technology is becoming a baseline expectation for live‑production facilities, and Wheatstone’s latest extension to Blade 4 I/O units and mix engines underscores that shift. By pairing dual engines that mirror each other in real time and monitoring a high‑frequency heartbeat, the system can detect a fault instantly and hand off processing to a standby unit without any audible or visual interruption. This approach eliminates the micro‑glitches that can derail live news, sports, or event broadcasts, aligning with industry standards such as SMPTE‑2022‑7 for video and AES67 for audio, which demand seamless packet delivery.

For broadcasters, the operational impact is significant. Traditional failover mechanisms often introduce a brief pause, forcing engineers to scramble for manual resets or risking on‑air errors. Wheatstone’s automatic, packet‑loss‑free transition reduces the need for human intervention, cuts downtime costs, and enhances compliance with service‑level agreements. As more facilities migrate to fully IP‑based audio‑video workflows, vendors that can guarantee uninterrupted traffic gain a competitive edge, positioning Wheatstone as a go‑to supplier for high‑stakes live environments.

The NAB Show also highlights Wheatstone’s broader product strategy with the introduction of the Audioarts DMX‑12 console. This compact surface combines a rack‑mount engine, multiple I/O options, and an integrated five‑port Ethernet switch, delivering a turnkey solution for both single‑room and networked studios. By bundling WheatNet IP connectivity directly into the console, Wheatstone simplifies system design and reduces cabling complexity, appealing to stations looking to modernize on a budget. Together, the hitless failover demo and the DMX‑12 showcase illustrate Wheatstone’s commitment to resilient, scalable, and user‑friendly broadcast technology.
