5-Pin Input Jack Wiring

The wiring diagrams included in this section repre-
sent the basic wiring necessary for the most common
types of microphones and other audio inputs. Some
microphones 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:

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 Wir-
ing Hookups for Different Sources. A length of
.065 OD clear tubing is included if you need to
insulate the resistor leads or shield wire.

Audio input jack wiring:
PIN 1
Shield (ground) for positive biased electret lavaliere
microphones. Shield (ground) for dynamic micro-
phones and line level inputs.
PIN 2
Bias voltage source for positive biased electret lava-
liere microphones that are not using servo bias cir-
cuitry 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
To Audio Amplifier
Pin 4 to Pin 2: 4 V
To Limiter Control
PIN 5
Line level input for tape decks, mixer outputs, musi-
cal instruments, etc.
Backshell
without strain
relief
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.
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 latch-
lock.
