Description
The BPHS1 is a rugged broadcast stereo 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 for news and
sports broadcasting, announcing and interviews.
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.
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 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 3.3 m (10.8') cable
terminating in two output connectors, one each for the microphone and
headphone: the microphone output is a 3-pin XLRM-type connector; the
headphones’ output is a 3-conductor ¼" connector. Three windscreens are
also included to protect against noise from breath and wind.
Operation & Maintenance
The BPHS1 broadcast 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. (Note: For stereo
monitoring, the earphone with a red insert on the yoke assembly carries
the right stereo channel.) 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 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.
To remove included 3.3 m (10.8') shielded 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.
The cable features a standard 3-pin XLRM-type microphone output
connector and a ¼" headphone output connector. Output from the
microphone’s XLRM-type connector is low impedance (Lo-Z) balanced.
The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output
phase is “Pin 2 hot”– positive acoustic pressure produces positive voltage
at Pin 2. The headphone ¼" connector is wired for stereo operation: the end
portion of the connector (Tip) carries the left channel; the center portion (Ring)
carries the right channel; and the bottom portion (Sleeve) 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.
