Description
The RTS PHS-A5M-300 is a single-sided broadcast headset designed for clear voice communications in live production and broadcast environments. It pairs an over-ear leatherette earpiece with a padded adjustable headband to provide stable long-wear comfort. The unit is built around a dynamic driver and a noise-canceling boom to keep speech intelligible in noisy conditions.
Key features include a dynamic noise-canceling boom microphone that can be mounted on either the left or right side and an adjustable boom for precise mic placement. The headset uses a single earpiece design to preserve situational awareness while delivering mono audio to the listener. A 5-pin XLR connector and a 6 ft cable provide industry-standard wired connectivity for intercom ports and partyline systems.
Technical performance is centered on a 300 Ohm headphone impedance and a dynamic driver with a frequency response of 200 Hz to 10 kHz for reliable voice reproduction. The microphone is a dynamic, noise-canceling element with a frequency response of 200 Hz to 6500 Hz, 200 Ohm impedance, and a sensitivity rating of -63 dB at 1 kHz. Maximum SPL is rated at 104 dB at 1 kHz / 1 mW, suitable for professional comms monitoring.
Connectivity uses a 1x 5-pin XLR audio connector on a 6 ft / 1.8 m cable, compatible with common intercom belt packs and base stations that accept 5-pin headset inputs. The headset is mechanically durable with metal components and leatherette padding for the earpiece and headband. The mic boom is interchangeable to support left or right side use without additional adapters.
Typical use cases include broadcast announcers, technical directors in live events, intercom operators, and studio stage managers who require one-ear monitoring with clear outgoing speech. The single-ear configuration maintains ambient awareness while providing an isolated audio channel for program or comms audio. The headset’s noise-canceling mic improves clarity in noisy control rooms and stage areas.
Installation and daily operation are straightforward – plug the 5-pin XLR into compatible intercom equipment, adjust the padded headband for fit, and position the adjustable boom for optimal vocal pickup. Built from leatherette and metal, the PHS-A5M-300 balances comfort and durability for extended shifts. This headset delivers dependable voice communication and straightforward integration into professional audio and intercom systems.
