5-Pin Input Jack Wiring; Installing The Connector - Lectrosonics SMB Series Instruction Manual

5-Pin Input Jack Wiring

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:

Installing the Connector:

1) If necessary, remove old connector from micro-
phone cable.
2) Slide Rubber Boot onto microphone cable with the
large end facing away from the microphone. (See
illustration above.)
3) If necessary, slide the 1/8-inch black shrink tub-
ing 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. 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.)

• PIN 1
electret lavaliere microphones. Shield (ground) for
dynamic microphones and line level inputs.
• PIN 2
electret lavaliere microphones.
• PIN 3
for dynamic microphones. Also accepts hand-
held electret microphones provided the micro-
phone has its own built-in battery.
• PIN 4
voltage (0, 2 or 4 volts) depends on Pin 4 con-
nection.

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 Latch-
lock.
6) If needed, position and shrink the 1/8-inch shrink
tubing 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.
