The Shure Models

DYNE'?

B Microphones are low-impedance units designed specifically for flexible gooseneck application. The microphones are moving coil units providing good reproduction of music and voice.

These microphones are particularly suitable for use in language lab systems, paging applications, and base station communications. They are highly recommended for

talkback and cuing from professional control rooms in TV, film, and recording studios, and other uses demanding a customized installation with concealed cables.

Features:

True cardioid pickup pattern: symmetrical about axis and uniform at all frequencies

Response especially effective for announcing, narration, paging and music

Cartridge shock-mounted for quiet operation

Built-in, non-locking, push-to-talk switch controls both microphone circuit and relay or control circuit

Dependability and ruggedness under all operating conditions

A 457 mm (18 in.) flexible gooseneck and a convenient mounting flange supplied with the Model

5SB-GI 8

To mount the

having a

5/8"-27

microphone (see Figure 1-A), remove adjacent thin metal washer and one metal spacer from terminating end of cable. Slide the thin metal washer removed

previously onto cable up into end of microphone. Slip

gooseneck over cable and install into end of micro-

phone.

CONNECTIONS

The microphones are low impedance for connec-

tion to microphone inputs rated at 19 to

300

The balanced line low-impedance connection is recommended where long cable lengths are

required or

under conditions of severe hum disturbance. The

permissible cable length is practically unlimited, since

neither response nor level is appreciably affected.

With reference to Figure

BLACK and RED are the

"hot" conductors for balanced line connections to a

low-impedance amplifier, the shield is connected to the amplifier ground. For unbalanced low-impedance operation, the shield and RED lead should be connected together. The BLACK lead is then the "hot"

lead. The

GREEN

and WHITE conductors are used to control an external relay or control circuit. It should be noted that hum susceptibility is increased in un-

balanced low-impedance operation.

amplifier has a high-impedance input. These trans-

formers provide a proper impedance match between a

19-300 ohm microphone line and

high-impedance input, and are available with various input and output connectors.

Important: Shure microphone cables are selected after exhaustive tests to insure superior performance in microphones because of low capacities, superior shielding properties and unusually long life under severe use.

Cables with plastic insulation should not be subjected to excessive soldering-iron heat. Carefully clean and tin the conductors and

the connections to which the conductors are to be soldered. The soldering operation can then be done with a minimum of heat, thereby avoiding any possibility of damage to the cable.
