Super-Minature Belt Pack Transmitter

Rio Rancho, NM

The wiring diagrams included in this section represent

the basic wiring necessary for the most common types

of microphones and other audio inputs. Some micro-

phones may require extra jumpers or a slight variation

on the diagrams shown.

It is virtually impossible to keep completely up to date

on changes that other manufacturers make to their

products, thus you may encounter a microphone that

differs from these instructions. If this occurs please call

5-Pin Input Jack Wiring

Audio input jack wiring:

PIN 1 Shield (ground) for positive biased electret lava-

liere microphones. Shield (ground) for dynamic

microphones and line level inputs.

PIN 2 Bias voltage source for positive biased electret

lavaliere microphones.

PIN 3 Low impedance microphone level input for

dynamicmicrophones.Alsoacceptshand-held

electret microphones provided the microphone

hasitsownbuilt-inbattery.

PIN 4 Bias voltage selector for Pin 3. Pin 3 voltage (0, 2

or 4 volts) depends on Pin 4 connection.

Pin 4 tied to Pin 1: 0 V

Pin 4 Open: 2 V

Pin 4 to Pin 2: 4 V

PIN 5 High impedance, line level input for tape decks,

mixer outputs, musical instruments, etc.

Installing the Connector:

1) If necessary, remove old connector from microphone

cable.

2) Slide Rubber Boot onto microphone cable with the

large end facing away from the microphone. (See illus-

tration above.)

3) Ifnecessary,slidethe1/8-inchblackshrinktubing

onto the mircrophone cable. (This tubing is needed

for some cables to ensure the cable ﬁts snugly in the

rubber boot.)

4) Use the resistors and connector included with this kit

to conﬁgure the TA5F to your particular microphone.

(SeeWiringDiagramsbelow.)Alengthof.065OD

clear tubing is included if insulating the resistor leads

or shield wire is necessary. (Remove rubber strain

relief from connector backshell by pulling it out of the

backshell.)

5) Slide the Strain Relief over the TA5F Insert and crimp

as shown to the right. Then insert the TA5F Insert

and Strain Relief in the TA5F Latchlock. Screw the

TA5F Flex Relief onto the TA5F Latchlock.

6) Ifneeded,positionandshrinkthe1/8-inchshrinktub-

ing on the microphone cable, then slide the Rubber

Boot down over the TA5F connector.

Note: If you use the dust boot, remove the

rubber strain relief that is attached to the TA5F

cap, or the boot will not ﬁt over the assembly.
