4 VOLT POSITIVE BIAS 3-WIRE ELECTRET

WITH EXTERNAL RESISTOR

This wiring is fully compatible with 5-pin inputs on Lectrosonics

transmitters such as the LM and UM Series. This is the wiring

for the Lectrosonics M152 lavaliere microphone.

Used for 3-wire lavaliere

microphones that require an

external resistor such as the

Sanken COS-11.

DPA MICROPHONES (Danish Pro Audio miniature models)

This wiring is for DPA lavalier

and headset microphones.

NOTE: The resistor value can range from 3k to 4k ohms.

BALANCED AND FLOATING LINE LEVEL SIGNALS

*NOTE: If the output is balanced but center

tapped to ground, such as on all Lectrosonics

receivers, do not connect Pin 3 of the XLR jack

to Pin 4 of the TA5F connector.

UNBALANCED LINE LEVEL SIGNALS

For signal levels up to 3V (+12 dBu) before limiting. Fully

compatible with 5-pin inputs on other Lectrosonics transmitters

such as the LM and UM Series. A 20k ohm resistor can be

inserted in series with Pin 5 for an additional 20 dB of

attenuation to handle up to 30V (+32 dBu).
