Input Jack Wiring for Different Sources
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.

Compatible Wiring for Both Servo Bias Inputs and Earlier Transmitters:
Simple Wiring - Can ONLY be used with
Servo Bias Inputs:
Servo Bias was introduced in 2005 and all trans-
mitters with 5-pin inputs have been built with this
feature since 2007.
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

and
click on Accessories, or download the master catalog.
A lot of information regarding microphone wiring is also
available in the FAQ section of the web site at:

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).
