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.
