MODEL W15HT/87
HANDHELD WIRELESS
MICROPHONE-TRANSMITTER
T h e S h u r e M o d e l W 1 5 H T / 8 7 i s a h a n d h e l d
microphone and radio transmitter for use with Shure
Wireless Microphone receivers. The W15HT/87 uses the
Shure SM87 supercardioid condenser microphone car-
tridge, the heart of one of the finest vocal microphones
available today, as its transducer element. Small, com-
p a c t a n d l i g h t w e i g h t , t h e W 1 5 H T / 8 7 i s h u m a n -
engineered for reliable, unobtrusive operation. The
grille is black Teflon coated, and the case is finished in
satin black enamel and ridged over its length for op-
timum gripping. The microphone cartridge is field-
replaceable and interchangeable with other Shure
W ireless Microphone cartridges.
All operating controls are located in a single area on
the microphone's outer surface, and are recessed to
minimize accidental movement. The W15HT/87's anten-
na combines a top-loading RF wire coil of appropriate
gauge and length, and the case section immediately
above the end cap.
The W15HT/87 uses a standard 9-volt transistor-
radio-type battery (alkaline, lithium or heavy-duty nickel-
cadmium recommended). The long-life alkaline battery
is available everywhere, and replacement is easily ac-
complished through a locking end cap. An LED in-
dicator provides information on battery condition.
The transmitter operates at a single, crystal-
controlled frequency in the VHF band between 150 and
216 MHz. A total of 15 frequencies, computer-selected
for interference-free operation, are readily available,
and other frequencies can be specially ordered. This
means that a number of wireless microphone systems
c a n b e o p e r a t e d i n a s i n g l e s o u n d i n s t a l l a t i o n ,
simultaneously and without intermodulation problems.

The W15HT/87's normal operating range is about 100
meters (330 feet). Operation at greater distances-300
meters (about 1,000 feet) or more - is often accomplish-
ed, but the determining factors in each installation will
be reflections, obstacles and interference.
The microphone is supplied with a zippered carry-
ing/storage bag, a swivel adapter for mounting the
W15HT/87 on most desk and floor stands, a lockplate
for locking the microphone in the "on" position, a small
screwdriver for adjusting the transmitter gain, and a
rubber plug to cover the microphone level adjustment
hole.
DESCRIPTION (see Figure 1)
ANTENNA: The W15HT/87's antenna system is not
visible. It consists of the case and grille, and a wire coil
inside the end cap.
BATTERY (not supplied): Only alkaline (Duracell
M N 1 6 0 4 o r e q u i v a l e n t ) , l i t h i u m ( K o d a k U 9 V L o r
equivalent), or heavy duty nickel-cadmium (8.4-volt)
transistor-radio-type batteries should be used. A fresh
alkaline battery should provide approximately 12 hours
of operation, lithium about 35 hours, and a fully charg-
ed, heavy-duty nicad should provide approximately 3
hours.
BATTERY COMPARTMENT: A locking twist-off end
cap exposes the battery compartment.
BATTERY TEST LED Indicator: Flashes briefly when
the POWER Switch is turned on and a "good" battery is
installed. Indicator will be on and clearly visible in room
light when the battery voltage drops to approximately
7.0 volts.
END CAP: The push-twist-remove end cap functions
as both battery cover and antenna coil holder. Note that
the end cap is color-coded internally to reflect the
W15HT/87's operating frequency as follows:

GRILLE: Protects the SM87 acoustic transducer of the
W15HT/87, and helps minimize the effects of breath
sounds and wind noise.
