Shure 515SDX Impedance Selection, Furnished Accessory, Optional Accessories, Replacement Parts

Impedance

LO Z: Microphone rating impedance is 150 Ω (270 Ω actu- al) for connection to inputs rated low impedance

HI Z: Microphone impedance is “High” for connections to high-impedance microphone inputs.

Output Level (at 1,000 Hz)
	LO Z		HI Z
Open Circuit Voltage:* –56.0 dBV/Pa		–37.5 dBV/Pa
(1.6 mV)		(14 mV)
*1 Pa = 94 dB SPL
Phasing

Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 in both HI Z and LO Z modes

Switch

Built-in ON/OFF switch, lockplate to lock switch ON

Connector

Certification

Conforms to European Union directives, eligible to bear CE marking; meets European Union EMC Immunity Re- quirements (EN 50082–1: 1992).

IMPEDANCE SELECTION

The microphone is shipped connected for low impedance operation. To change to high impedance, refer to Figure 4 and proceed as follows:

1.Remove plug element by turning slotted setscrew in (counterclockwise). Use long-nose pliers to pull plug element from case, but be careful not to stretch or break

wires.

2.Disconnect 2-terminal impedance selection socket from rear of plug element by prying it off pin 3.

3.Reconnect impedance selection socket so that pin 3 of plug element is now connected to RED (high-impe- dance) lead.

4.Swivel socket so that it does not extend beyond edge of connector (see inset in Figure 4).

5.Reinsert plug element into microphone; then tighten set- screw by turning it clockwise.
