maximum. Operation at greater distances -300 meters

(1,000 feet) or more-is often accomplished, but the

determining factors in each installation will be reflec-

tions, obstacles and interference.

The transmitter is supplied with a zippered carrying

storage bag and a small screwdriver for adjusting the

transmitter gain.

The Shure Model W10BT is a body-pack radio

transmitter for use in the Shure Wireless Microphone

System. Small, compact and lightweight, the W10BT is

human-engineered for reliable, unobtrusive operation.

The microphone connector and all operating controls

are located on the upper surface, and the controls are

differentiated in size and shape to minimize incorrect or

accidental movement. (The gain control is generally

only used in setup, and is therefore recessed on the rear

panel.) A rugged belt clip provides secure attachment to

a belt, pocket or waistband. The antenna, a short piece

of thin, highly flexible wire, is an optimum choice for

minimum visibility and maximum durability.

The W10BT uses a standard 9-volt transistor-radio-

type battery (alkaline recommended). This long-life bat-

tery is available everywhere, and replacement is easily

accomplished through a locking slide-off cover plate; no

screws or hinges are used. A battery test switch and

LED indicator provides information on battery condi-

tion.

The transmitter operates at a single, crystal-

controlled frequency in the VHF-FM 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 ordered on a

special basis. This means that a number of wireless

microphone systems can be operated in a single sound

installation, simultaneously and without intermodula-

tion problems.

The W10BT has a maximum output power of 50

milliwatts, based on Federal Communications Commis-

sion regulations. This means that the transmitter-to-

receiver-antenna distance should be kept as short as

possible, with about 150 meters (500 feet) considered a

DESCRIPTION (see Figure 1)

ANTENNA: This is a flexible, 1/4-wave vertically

polarized antenna approximately 30 cm (12 in.) in length

and permanently attached to the bottom surface of the

transmitter. For proper operation, the antenna must be

in the vertical position, not coiled or bundled.

BATTERY (not supplied): Only alkaline (Duracell

MN1604 or equivalent) or heavy-duty nickel-cadmium

(8.4-volt) transistor-radio-type batteries should be used.

A fresh alkaline battery should provide approximately 8

hours of operation, and a fully charged nicad should pro-

vide 1-1/2 to 2 hours.

BATTERY COMPARTMENT: Slide-off cover exposes

the battery compartment.

BATTERY TEST Push-Button Switch: Permits checking

the condition of the installed battery when the power

switch is on. The Battery Test LED Indicator will fail to

light if the battery is weak or dead (or if the Power switch

is off). Note that if the battery is tested periodically dur-

ing

use,

an impending battery failure can be

detected: the LED will fail to light at 7.25 volts. At that

time, approximately 1 hour of battery life remains

(alkaline batteries only).

BELT CLIP: Permits convenient attachment to the

user’s belt, waistband or other clothing.

GAIN HI/LO Slide Switch: Selects the High Gain posi-

tion to boost the signal of low-output (low-impedance)

microphones, or the Low Gain position for high-output

(high-impedance) microphones or musical instruments.

Allows maximum modulation without clipping.

MICROPHONE JACK: This is a 4-pin, miniature, male

Tini Q-G connector designed to mate with Switchcraft

TA4F or equivalent connectors. A built-in 20-kilohm load

resistor provides proper matching for dynamic, ribbon or

condenser microphones. Connector pin 2 supplies

+5-volt bias voltage for condenser microphone phan-

tom powering. In addition to microphones with TA4F

connectors, Shure has available an adapter cable with a

standard XLR female connector for use with conven-

tional microphones (WA310), and a musical instrument
