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 congured 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.
Architect’s and Engineer’s Specications
The headset shall be a communications headset with closed-back ear
cups and a boom-mounted microphone that can be positioned on the left
or right side.
Padded circumaural ear cups shall provide acoustic isolation; the
headband shall be adjustable and cushioned. The earphones shall have
an extended frequency response of 20 Hz to 20,000 Hz, and shall be
equipped with 40 mm neodymium drivers.
The microphone shall be a moving coil dynamic with a neodymium
magnet. It shall have a cardioid polar pattern and a frequency response of
40 Hz to 20,000 Hz. Nominal open-circuit output voltage shall be 1.4 mV
at 1V, 1 Pascal. Output shall be low impedance balanced (560 ohms). The
boom shall be of a pivoting, exible design.
The headset shall have a 2 m (6.6') user-replaceable detachable cable
terminating in a 4-pin XLRF-type connector providing unbalanced audio from
the microphone and delivering a mono signal to the headphone.
Weight shall be 264 g (9.3 oz). The headset shall include three windscreens.
Finish shall be low-reectance black.
The Audio-Technica BPHS1-XF4 is specied.
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
