Shure 510MD User Guide

GENERAL:

Model 510 MD is an integral assembly of a Controlled Reluctance Microphone and desk stand with a built-in switch. The microphone has a 4000 ohm impedance, high output, smooth response, and a semi-directional pickup charac- t e r i s t i c .

The non-locking switch in the desk stand is a two pole, single throw, normally open switch. The switch may be used to control both the microphone circuit and an external relay or control circuit.

The microphone, as supplied, is wired to control only an external relay or control circuit. For " on-off " control of the microphone circuit also, clip jumper lead (R),

Jumper lead (R) should also be clipped in any application where two or more Model 510 MD microphones are used in parallel.
