Dynamic Microphones

NEW SHURE SERIES 5

MOVING-CONDUCTOR TYPE DYNAMIC MICROPHONES

GENERAL: Pressure-operated moving-conductor type dynamic microphones with typical semi-directional pickup. Smooth response

due to specially designed moving system and associated acoustic network.

APPLICATIONS: For music and voice reproduction. Suitable for low cost P. A., call systems, amateur phone and similar applications.

Rugged and immune to severe temperature and humidity conditions.

INSTALLATION: 5/8”-27 thread for standard desk and floor stand mounting.

CONNECTIONS: Internal high quality transformer included in all models. The output impedances and cables furnished are listed

below:

Model	Impedance			Cable
5E-25FT	30-50	ohms	25 ft. two-conductor
5F-25FT	200-250	ohms	25	ft. two-conductor
5G-25FT	High Impedance 25			ft. single-conductor
5G	High Impedance		7	ft. single-conductor

Low impedance models 5E and 5F are recommended for use with long lines into standard low

impedance input amplifiers. Permissible cable length practically unlimited. For amplifiers with high impedance input, Shure Model A86A Cable-Type Transformer is available for coupling low impedance line to amplifier.

High impedance model 5G (5G-25FT.) can be used with any crystal microphone amplifier or other amplifier with input impedance of 100,000 ohms or more. Inner conductor of cable connects to grid side of input, "shield" to ground of amplifier. Cable lengths longer than 25 ft. accompanied by some loss of high frequency response.

Recommended	Model	5E	35-50 ohms
Load	Model	5F	200-250	ohms
Impedance :	Model	5G	100,000	ohms or more

PRECAUTIONS: No special precautions beyond ordinary care necessary. To retain full strength of permanent magnet and main-

tain alignment of structure, dropping or other severe mechanical shocks should be avoided. Care should be taken that the cable does not parallel A.C. power lines for long distances.

GUARANTEE: Each microphone is guaranteed to be free from electrical and me- chanical defects for a period of one year from

date of shipment from the factory, provided all instructions are complied with fully. In case of

damage return microphone to factory for repairs. Our guarantee is voided if microphone case is opened.
