Description

The BPHS1-XF4 is a rugged communications headset with closed-back circumaural (around-the-ear) ear cups and a professional boom-mounted microphone that can be worn on either side. It is designed to be used with intercom systems.

The headset’s microphone has a cardioid polar pattern tailored for pickup of speech with maximum voice intelligibility over a wide range of frequencies. It is more sensitive to sound originating directly in front of the element, making it useful in reducing pickup of unwanted sounds. The exible gooseneck boom swivels for easy positioning on either the right or left side.

broadcast & production microphones

optimal performance: Positioning the microphone closer to your mouth will increase the low-end response for a more robust, full-range sound. As you move the microphone away from your mouth, the low-end response will diminish.

The included 2 m (6.6') shielded cable (BPCB4) features a 4-pin XLRF-type connector. To remove cable, loosen and remove the thumb screw and pull the multi-pin connector out of its socket. To replace the cable, plug the multi-pin connector into the socket, replace and tighten the thumb screw.

Output from the microphone is low impedance (Lo Z) unbalanced. The microphone signal appears across Pin 2 and Pin 1; Pin 1 is ground (shield). Output phase is “Pin 2 hot” – positive acoustic pressure produces positive voltage at Pin 2. The cable is congured for mono headphone operation: Pin 4 carries the signal; Pin 3 carries the ground.

Take care to keep foreign particles from entering the windscreen. An accumulation of iron or steel lings on the diaphragm, and/or foreign material in the windscreen's mesh surface, can degrade performance.

The Audio-Technica BPHS1-XF4 is specied.

The dual earphones offer an extended frequency response of 20-20,000 Hz and smooth, natural sound reproduction. At the heart of each earpiece, a 40 mm neodymium driver offers impressive power handling ideal for high maximum sound pressure levels. Generously padded circumaural ear cups provide acoustic isolation and long-wearing comfort; the adjustable headband is also crafted and cushioned for listening comfort.

The headset includes a user-replaceable detachable 2 m (6.6') cable terminated in a 4-pin XLRF-type connector providing unbalanced audio from the microphone and delivering a mono signal to the headphone. Three windscreens are also included to protect against noise from breath and wind.

Operation & Maintenance

The BPHS1-XF4 communications headset features a exible microphone boom that pivots so that it can be worn on either side of the face. Put on the headset with the microphone boom on the desired side. Adjust the boom as needed to follow the contour of your face, positioning the microphone near the corner of your mouth. Experiment with placement for
