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 lavaliere 

microphones. Shield (ground) for dynamic microphones 

and line level inputs.
PIN 2  

Bias voltage source for positive biased electret lavaliere 

microphones that are not using servo bias circuitry and 

voltage source for 4 volt servo bias wiring.
PIN 3 

Microphone level input and bias supply.
PIN 4 

Bias voltage selector for Pin 3. 

Pin 3 voltage 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 

Line level input for tape decks, mixer outputs, musical 

instruments, etc. 

Installing the Connector:

1)   If necessary, remove the old connector from the 

microphone cable.

2)  Slide the dust boot onto microphone cable with the 

large end facing the connector.

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

onto the mircrophone cable. This tubing is needed 

for some smaller diameter cables to ensure there 

is a snug fit in the dust boot.

4)  Slide the backshell over the cable as shown above. 

Slide the insulator over the cable before soldering 

the wires to the pins on the insert.

5)  Solder the wires and resistors to the pins on the 

insert according to the diagrams shown in 

Hookups for Different Sources. A length of .065 

OD clear tubing is included if you need to insulate 

the resistor leads or shield wire.

6)  If necessary, remove the rubber strain relief from 

the TA5F backshell by simply pulling it out.

7)  Seat the insulator on the insert. Slide the cable 

clamp over the and of the insulator and crimp as 

shown on the next page.

8)  Insert the assembled insert/insulator/clamp into 

the latchlock. Make sure the tab and slot align 

to allow the insert to fully seat in the latchlock.

Thread the backshell onto the latchlock.

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.
