2 VOLT POSITIVE BIAS 2-WIRE ELECTRET
Simplified wiring for microphones 
such as Countryman B6 Lavalier 
and E6 Earset models and others.
NOTE:  This servo bias wiring is not compatible with earlier 
versions of Lectrosonics transmitters. Check with the factory 
to confirm which models can use this wiring.
Compatible Wiring for Both Servo Bias Inputs and Earlier Transmitters:
Simple Wiring for Servo Bias Inputs Only:
4 VOLT POSITIVE BIAS 3-WIRE ELECTRET
NOTE:  This servo bias wiring is not compatible with earlier 
versions of Lectrosonics transmitters. Check with the factory 
to confirm which models can use this wiring.
Wiring Hookups for Different Sources
In addition to the microphone and line level wiring hook-
ups illustrated below, Lectrosonics makes a number of 
cables and adapters for other situations such as con-
necting musical instruments (guitars, bass guitars, etc.) 
to the transmitter. Visit

2 VOLT POSITIVE BIAS 2-WIRE ELECTRET 
Compatible wiring for microphones such as 
Countryman E6 headworn and B6 lavaliere.
4 VOLT POSITIVE BIAS 2-WIRE ELECTRET
Most common type of wiring for lavaliere mics. 
Fully compatible with 5-pin inputs on Lectrosonics 
transmitters such as the LM and UM Series.

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.

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).
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.

and headset microphones.
NOTE:  The resistor value can range from 3k to 4k ohms.
2 VOLT NEGATIVE BIAS 2-WIRE ELECTRET
Simplified wiring for microphones such as negative bias TRAM.
NOTE:  This servo bias wiring is not compatible with earlier 
versions of Lectrosonics transmitters. Check with the factory 
to confirm which models can use this wiring.
