What Makes the Pyro Ultra Different?
-
Focus Mode & Low Latency: For critical focus-pulling tasks, activating Focus Mode drops latency down to a highly responsive ~20ms on 1080p feeds (~45ms on 4K60).
-
The "Infinite" Ecosystem: While this kit comes with two receivers, the system features a Broadcast Mode allowing you to transmit to an unlimited number of Pyro Ultra receivers simultaneously. It is also backward-compatible with the existing Pyro ecosystem (Pyro S, H, 7, 5).
-
Smart Signal Management: In the event of a sudden signal interruption, the system triggers a Freeze Frame feature (or displays a pre-uploaded custom brand logo) rather than letting the screen cut to a jarring black or blue screen, protecting the continuity of live views.
-
Dual Power Choices: Both units feature an integrated battery plate designed for Sony NP-F series batteries, alongside a standard 6–16V DC barrel input for locking mains or D-Tap rigging power.
What's In The Box?
This complete production bundle typically ships in a hard-shell carrying case containing the single transmitter, two receivers, a multi-pack of both standard and short-profile antennas, mounting ball heads, a 12V DC power adapter, a D-Tap to DC cable, and USB-C adapters.
