RTS NC450A-6PIN PTT Hand Microphone / Noise-Canceling Dynamic / Coiled Cable 1.5 to 6 ft / A6M 6-Pin

Description

The NC450A PTT hand microphone is a push-to-talk handheld microphone designed for clear voice paging and communication. It combines a noise-canceling dynamic capsule with an ergonomic housing for comfortable handheld operation. The microphone delivers reliable speech intelligibility in both noisy and quiet environments.

Key features include a large push-to-talk button for positive tactile control, a noise-canceling dynamic element that rejects ambient noise, and a coiled cable that extends from 1.5 to 6 ft to reduce tangling. The housing is compact and shaped for secure grip during extended use. The element is optimized for voice frequencies to produce natural speech response.

Performance characteristics include a frequency range of 100 Hz to 8 kHz, an impedance of 200 Ohms, and a sensitivity of -64 dBV/Pa. These specifications provide consistent level matching with paging consoles and intercom systems. The dynamic capsule and tailored response deliver clear communication without needing external power.

Connectivity is provided via a 6-pin A6M XLR-style connector compatible with industry-standard intercom and paging interfaces. The microphone terminates in a 6-pin male connector for direct connection to compatible base stations and belt packs. The coiled cable measures 1.5 to 6 ft (0.45 to 1.8 m) stretched, preserving desk or operator mobility while minimizing slack.

Typical applications include voice paging in facilities, intercom or crew communication in broadcast environments, and theatrical or production back-of-house communications. The noise-canceling design keeps spoken messages intelligible in production galleries, machine rooms, and noisy public areas. The compact form factor makes it easy to hand off or mount in operator stations.

Installation and operation are straightforward – connect the 6-pin A6M plug to the compatible input, and use the push-to-talk control for instant transmit. The rugged construction and balanced dynamic element support long service life in professional environments. The NC450A is a practical choice where dependable voice clarity and simple control are required.
