UNIDIRECTIONAL DYNAMIC MICROPHONES

GENERAL

The Model 580 Series moving coil dynamic units built to provide wide range reproduction of music and voice and featuring an excellent unidirectional microphone pickup pattern. These unidirectional microphones are ideal for quality public address, theater-stage sound systems, recording, and other sound reinforcement applications.

Microphone Features:

Exceptional true cardioid pickup pattern: symmetrical about axis and uniform at all frequencies-providing highly effective suppression of

feedback

Uniform shaped response, particularly suitable

for the professional entertainer

built-in On-Off switch with provisions for lock-

ing switch in its On position

Versatility-for use in the hand or on a standfor use indoors or outdoors

Dependability under all operating conditions

The Model 580 Microphones are supplied with an adjustable swivel adapter which permits the microphone to be tilted through 90" from vertical to horizontal. This swivel also allows for "quick-disengage" for use as a hand microphone.

Model

high-impedance microphone inputs.

Model

microphone inputs rated at 19 to 300 ohms. The impedance microphone 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 by long cables. Shure Model A95 Series Line Matching Transformers are available for use in those cases where a low-impedance microphone line is desirable but the associated amplifier has a high-impedance input. These vide a proper impedance match between a 19 to 300 ohm microphone line and a high-impedance input and are available with various input and output connectors.

PHASING

To test two microphones for proper phasing, connect them to an amplifier and talk or sing into them while holding them three or four inches apart. The sound from the speakers should be the same when talking into either microphone or directly between them

if they are in phase with each other. If the sound drops drastically, or if a dead spot is found when talking between the two microphones, the microphones are out of phase. All microphones should be tested in this

manner to insure that they are in phase with each other.

To change the phase of a low-impedance micro-

phone at the equipment end of the cable, interchange the BLACK and WHITE cable leads where they are connected to the sound system. To change the phase of a microphone, the microphone cartridge leads must be interchanged (see Figure 4). This should be performed by your dealer, the Shure Factory Service Department, or other qualified service personnel.

CARTRIDGE

ARCHITECTS' SPECIFICATIONS

The microphone shall be a moving coil (dynamic)

type with a frequency response of 50 to 13,000
