GENERAL

The Shure 514B is a low impedance, dynamic, hand-held

microphone designed for paging and public address systems. It

provides clear, natural voice response and high intelligibility.

The 514B connects to microphone inputs rated at 19 to 300 .

It can be used in applications that require long cable lengths, or

where severe hum conditions are present. For connection to high

impedance inputs, use Shure A95 Series Line Matching Trans-

formers.

The microphone is provided with a four-conductor (two

shielded) coiled cable and a “Million-Cycle” leaf-type switch

designed for constant use under the most rigorous conditions. The

514B fits naturally and comfortably in the hand and is not affected

by heat or humidity. The exclusive ARMO-DUR

 case resists

mechanical shocks and vibration, and is impervious to oil, fumes,

salt spray, ultraviolet radiation, and corrosion.

Features

•Smooth, extended frequency response from 100 to 6,000 Hz-pro-

vides highly intelligible voice response

•“Million-Cycle” leaf-type switch-provides outstanding reliability,

even under extreme conditions

•Tough ARMO-DUR

microphone

CONNECTIONS

Refer to Figure 1 and Table 1 below. The GREEN wire is con-

nected to the positive audio input, the WHITE wire is connected to

the negative audio input, and the SHIELD is connected to chassis

ground. The RED and BLACK leads control the external relay or

switching circuit.

INTERNAL CONNECTIONS

FIGURE 1

Table 1. Typical Cable-to-Connector Wiring

NOTE: The RED and BLACK leads are not part of the audio

circuit. These wires provide a contact closure when the

press-to-talk switch is depressed. This closure may be used to

control an external relay or a transmit/receive circuit.

OPERATION

To operate the microphone, simply hold down the press-to-talk

switch and begin speaking. Release the switch when you are fin-

ished speaking.

MOUNTING

The 514B is supplied with a mounting bracket to provide a

snap-in hang-up for the microphone when it is not in use. The

bracket has mounting holes with clearance for No. 8 screws. See

Figure 2 below.
