CANNON XLR Connectors for Broadcast Camera Audio Systems in Japan

Project Background

Japan’s broadcast and film production industry is globally recognized for its high standards in audio and video quality. In live broadcasting, documentaries, and professional filmmaking, broadcast cameras play a central role, while stable and noise-free audio transmission is critical to overall production performance.

In a new broadcast camera audio interface project in Japan, a professional audio cable supplier encountered limitations with conventional connectors, including unstable contact, insufficient electromagnetic interference (EMI) resistance, and limited durability under frequent use. These issues occasionally resulted in signal dropouts and background noise during filming. To meet broadcast-grade requirements, the project adopted CANNON XLR connectors to ensure reliable audio connections between broadcast cameras, microphones, and mixing consoles.

Application Challenges

The audio connection system was required to perform reliably in both studio and field-production environments. Key challenges included:

Audio signal purity: Filming locations contain lighting systems, wireless equipment, and power sources that generate electromagnetic interference, requiring high shielding performance to maintain clean 48kHz/24-bit audio transmission.

Connection stability: Broadcast cameras are frequently moved, and audio devices are connected and disconnected multiple times per day, increasing the risk of loose contacts.

Environmental adaptability: Outdoor filming exposed connectors to dust, light rain, and low temperatures, demanding enhanced mechanical and environmental protection.

High mating durability: Intensive daily workflows required connectors capable of long-term use without performance degradation.

Standards compliance: The solution needed to comply with Japanese and international safety and environmental regulations for professional broadcast equipment.

To address these challenges, CANNON XLR connectors were selected and optimized for broadcast camera audio applications.

High EMI Shielding and Stable Transmission
A full metal shielding structure combined with gold-plated contacts significantly reduces electromagnetic interference and minimizes signal loss. Low contact resistance ensures stable, low-noise audio transmission that meets broadcast-quality standards.

Secure Locking Design
The latch-lock mechanism prevents accidental disconnection caused by camera movement or cable tension, ensuring uninterrupted audio signals during live broadcasting and on-location shooting.

Environmental Protection and Mechanical Strength
With an IP54 protection rating and integrated sealing components, the connectors can withstand dust exposure and light rain. They are designed for a wide operating temperature range, making them suitable for both indoor studios and outdoor filming environments.

Long Service Life and Flexibility
Optimized contact materials support up to 20,000 mating cycles, significantly reducing replacement frequency. The connectors are available in 3-pin and 5-pin configurations to support mono and multi-channel audio applications.
