High-Impedance Controlled Magnetic Microphones

General:

phones are pressure operated magnetic units using the armature Controlled Magnetic principle. The microphones have high impedance, high output, smooth response and a semi-directional pickup characteristic. The stability of these microphones is assured by unique control of the reluctance of the magnetic system. High impedance is obtained without the use of a transformer. The Model "510" series microphones have a sturdy die-cast case.

circuil. Model 5 10C has no switch.

Each of the microphones in the "510" series is provided with a

7-foot (2.1 m) single conductor, shielded cable.

Applications:

ruggedness, the clear reproduction, and the high output needed in

many applications. These microphones may be used in fixed and

mobile address systems (including carnivals, circuses, parking

lots, paging systems, etc.), communications, dictating machines,

portable recording machines, home recording, language lab sys-

tems and high quality inter-communication. These microphones are

unusally rugged and are practically immune to severe moisture and

temperature conditions-which makes them especially ideal for use

in tropical and coastal areas.

Also, the Model "510" series microphones may be used in

applications requiring a soft speaker or receiver.

Connections:

public address amplifier or other of 100.000 ohms or more.

The inner or "hot" conductor of the cable should be connected to the grid of the first tube in the amplifier across a load resistance of 100,000 ohms or more. The shield should be connected to the

chassis or amplifier ground. The shield, chassis or amplifier ground should be securely grounded to a water pipe or similar ground to prevent shock hazard during operation of the amplifying system.

Cable lengths some loss of high frequency response.

In certain amplifiers, the grid bias is obtained

phone and the input grid. The condenser should be

For momentary contact, depress switch button and release. For lock-

ing, depress switch button and slide button upward.

In some applications the locking feature is not desired and

may be eliminated in the following manner: Remove the two 4-40 oval head remove rear cover. Remove the two 5-40 oval head machine screws
