RTS HR-2 – Intercom & Commentary Units / Accessories

The HR-2 is a passive 2-ear noise-cancelling headset with XLR5M connectors. It does not contain embedded control logic; protocol compatibility depends entirely on the RTS mainframe or control unit it terminates into. Verify your RTS system's XLR5 pinout and control protocol (typically RTS proprietary or DANTE-based on the mainframe). Integration requires matching the headset termination to your existing infrastructure. Consult your RTS system documentation for pin compatibility before procurement.

The HR-2 features standard XLR5M connectors, but RTS XLR5 pinouts are proprietary. Use with non-RTS systems only if their control units support identical XLR5 pin assignment. Direct cross-platform compatibility is not guaranteed. We recommend confirming connector pinout and control signal specifications with your current mainframe vendor before substituting HR-2 units. Many broadcast facilities standardize on a single manufacturer to avoid integration issues.

The HR-2 delivers noise-cancelling performance across both ear cups, optimized for outdoor broadcast and OB van operations. Exact frequency response, THD, and cancellation depth are configuration-dependent on the RTS system feeding it. Field-proven in live sports and news. For detailed audio specs—headroom, presence peak, rejection characteristics—contact RTS directly. Performance scales with mainframe audio conditioning and input gain structure; verify your system's output stage meets broadcast audio standards.

The HR-2 quantity supplied is 2 units with XLR5M connectors. Your RTS mainframe's port count and user capacity determine total headset load. Each mainframe model (4000, 4001, etc.) has fixed XLR5 output slots and licensed user limits. Confirm your RTS mainframe specifications—port count and maximum simultaneous users—before scaling beyond supplied units. Exceed those limits and you'll need additional mainframes or a distributed control architecture.

The HR-2 is a wired XLR5M headset with no embedded electronics, making ear cushions and cable the primary wear items. RTS publishes a service parts list; ear foam and replacement cables are standard stock items. Headsets themselves are field-swappable in seconds with zero reconfiguration. No firmware or control data is stored on-device. For OB operations, maintain at least two spare ear cushion sets per headset to sustain 24/7 operations. Verify parts availability through your RTS distributor.

Standard HR-2 cable length is not specified in available documentation. XLR5 cable runs to intercom positions typically range 10–50 feet in studio; OB applications vary widely. RTS supplies custom cable lengths and remote terminus panels. For large OB vans or arena setups, confirm cable routing early and order extended runs during system design. Standard lengths may not reach all workstations; custom cable assemblies avoid daisy-chaining and impedance issues. Contact RTS applications engineering with your venue drawing.

The HR-2 itself is a passive slave device; redundancy depends on your RTS mainframe architecture. Dual-mainframe systems with automatic failover are standard in mission-critical broadcast. Each HR-2 connects to one mainframe XLR5 port. To implement redundancy, configure dual mainframes with cross-connected speaker and microphone paths, then terminate HR-2 units into both frames (or use quick-disconnect panels). RTS systems support this; your system integrator must design the failover logic and test switchover time.

The HR-2 is a hardwired analog XLR5M headset with no native IP or DANTE interface. It connects only to RTS analog XLR5 outputs. IP-native RTS systems (DANTE, Omneo, networked platforms) still require analog output cards or edge converters to drive XLR5 headsets. Verify your RTS platform includes analog headset breakout modules. If upgrading to IP infrastructure, plan for analog–digital conversion at intercom terminus points; the HR-2 remains a cost-effective endpoint but depends on proper D/A termination hardware.

Detailed microphone sensitivity, output impedance, and phantom power requirements depend on RTS mainframe configuration and are not available in baseline product specs. Most RTS headset microphones operate on mainframe-supplied phantom power (typically +48 V). Before installation, verify your RTS system's microphone power output and expected input sensitivity. Field adjust gain at the mainframe to prevent overload or noise. Test with your existing intercom configuration before large-scale deployment to confirm audio levels across all positions.

Yes. Our used and ex-demo units undergo a full functional inspection — sensors, video outputs, control signals, optics and mechanics — including a colorimetry and sensitivity test. Each product is tested by our technicians and comes with a 90-day warranty. Contact us for the specific warranty terms of the unit you are interested in.
