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 

our toll-free number listed under Service and Repair in 

this manual or visit our web site at:

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. 

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.

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.
