GENERAL

The Shure Beta 5 3 i s a s ubminiature, e lectret c ondenser headworn m icrophone. It is
intended for w ireless u se i n s ound r einforcement a pplications t hat r equire m inimal v is­ibility and maximum mobility, such as stage performances.

Despite its small size, the microphone element provides full, articulate reproduction
of speech and vocals, and features an omnidirectional pick-up pattern.

The Bet a 5 3 c o n si s ts of an adjustable wireframe a nd boom that allows flexible p lace­ment of t he m icrophone c artridge. It is a ls o s upplied w ith t wo d ifferent e qualization c aps
that tailor the microphone’s high-frequency response. Acoustic windscreens are sup­plied to minimize wind noise.

MODEL VARIATIONS

WBH53B: Black microphone with 5’ cable, terminated with a TA4F connector.
WBH53BX: Black microphone with 10’ cable, no connector.

ACCESSORIES
Windscreens. Acoustic foam windscreens are supplied to help reduce undesirable

wind and breath noise.
Equalization Caps. The Beta 53 is supplied with two types of equalization caps for

high frequency response shaping. The caps differ in response between the frequen­cy range of 5,000 to 20,000 Hz (see Figure 8), and can be distinguished by their
mesh color . The mild boost equalization cap has a silver mesh screen, while the high
boost equalization cap has a gold mesh screen.

Clothing Clip. A clothing clip is supplied with the Beta 53 for cable management
and additional strain relief.

USING THE BETA 53 IN HARDWIRED APPLICATIONS

An in-line preamplifier (Shure part no. RPM626) may b e u sed w ith t he B e ta 5 3. T his
device requires phantom power ranging from 11 to 52 Vdc.

USING THE BETA 53 WITH OTHER BODYPACK TRANSMITTERS

If connecting the microphone to anything OTHER than a Shure wireless bodypack,
make sure it provides a regulated +5 Vdc source (130

mA minimum) to the red con-

ductor, as shown in Figure 1.

REVERSIBLE AND ADJUSTABLE BOOM

The Beta 53 boom can be placed on either side of the wireframe. Snap the boom
into the boom clip, which can be rotated as shown in Figure 3. The boom can also
slide forward and backward in the boom clip to adjust the microphone-to-mouth dis­tance. CAUTION! Do not attempt to bend the boom itself. Adjust the boom by rolling
it closer to or further away from the mouth.

WEARING THE WBH53

Place the wireframe around your head so the earforms go over the ears from behind
and the wireframe lays horizontally across the base of the skull (see Figure 4).

POSITIONING THE MICROPHONE

For best performance, the Beta 53 microphone should be placed at the corner of the
mouth, and as close to the mouth as possible without touching any skin or facial hair
(see Figure 5). If necessary, the boom can be “rolled away” from the mouth to avoid
contact with facial hair (see Figures 6 and 7).
