RTS PTT-A4M PTT Hand Mic / Noise-Canceling Dynamic Cardioid / A4M Connector / Coiled 1.5 to 6 ft

Description

The PTT hand microphone is a compact push-to-talk microphone designed for voice paging and intercom environments. It combines an ergonomic handheld form factor with a large, easy-to-operate push-to-talk switch to support rapid voice transmission. The microphone is tuned to deliver clear speech intelligibility in both quiet and noisy conditions.

Key features include a noise-canceling dynamic capsule and a cardioid polar pattern that reject off-axis noise while preserving natural vocal presence. The housing is shaped for comfortable long-term handling and the large PTT control minimizes accidental activations. A coiled cable extends from 1.5 to 6 ft to reduce tangling and provide flexible reach.

Performance is optimized for speech with a frequency response of 100 Hz to 8 kHz and a sensitivity of -64 dBV/Pa. The microphone presents a nominal impedance of 200 ohms which is compatible with common analog intercom and paging inputs. The cardioid pattern focuses pickup on the speaker while rejecting ambient noise for clearer transmission.

Connectivity is provided via an A4M 4-pin XLR male connector suitable for analog intercom and paging systems. There is no USB or digital audio output, ensuring simple analog integration with legacy and professional AV equipment. The microphone weighs approximately 10 oz, making it lightweight and easy to mount or hand-hold during operations.

Typical applications include voice paging, facility intercom, broadcast communication consoles, and live-event talkback where reliable push-to-talk operation is required. The noise-canceling design performs well in busy or loud environments such as control rooms, production booths, and industrial sites. It also provides high-quality voice reproduction in quieter settings where clarity and natural vocal tone are important.

Installation and use are straightforward – connect the A4M connector to compatible equipment, extend the coiled cable as needed, and press the PTT button to speak. The construction and component choices target dependable daily operation and intuitive ergonomics for operators. The PTT hand microphone delivers a focused speech response and simple analog connectivity for professional AV setups.
