Wisycom Expands MPR60 With New Multichannel IFB Mode

Why It Matters

The upgrade gives broadcasters higher channel density with a smaller RF footprint, cutting equipment costs and simplifying OB truck designs for large‑scale live events.

Key Takeaways

• Multichannel IFB mode supports three audio channels on 200 kHz carrier
• Delivers up to 60 IFB channels in an 8 MHz TV band
• Cuts rack space, removing need for extra transmitters and combiners
• Firmware v1.3.0/2.6.0 and license release scheduled April 22, 2026
• IP65 rating ensures dust and water resistance for mobile productions

Pulse Analysis

In the fast‑moving world of live broadcast, the ability to push multiple IFB (interruptible feedback) feeds through limited spectrum has become a competitive edge. Traditional single‑channel IFB setups often require separate transmitters, combiners and antennas, inflating both weight and cost on outside‑broadcast (OB) trucks. Wisycom’s new multichannel mode leverages a 200 kHz carrier to squeeze three audio streams together, a technical leap that aligns with the industry’s push toward leaner, more agile RF architectures.

The practical impact of this firmware update is immediate. By fitting up to 60 IFB channels into a standard 8 MHz TV allocation—or 45 channels in a tighter 6 MHz slot—broadcasters can support extensive commentator lines, multilingual feeds, and real‑time production cues without expanding their spectral footprint. The reduction in hardware—one MTK982 replacing two transmitters and eliminating combiners—translates into measurable savings on chassis space, power consumption, and maintenance. Moreover, the IP65 rating adds resilience for outdoor and mobile deployments, ensuring reliable performance in dust‑laden stadiums or rain‑soaked concert venues.

Wisycom’s announcement at the 2026 NAB Show signals a broader market shift toward high‑density, software‑driven RF solutions. As streaming platforms and global sports rights demand ever‑greater production complexity, equipment that maximizes channel count while minimizing footprint will be prized. Competitors will likely accelerate similar firmware innovations, but Wisycom’s early‑access licensing model and backward‑compatible companders give it a head start. Broadcasters adopting the new MPR60 mode can expect faster setup times, lower capital expenditures, and the flexibility to scale IFB infrastructure as live‑event demands evolve.
