The wiring diagrams included in this section represent
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 prod-
ucts, thus you may encounter a microphone that diers
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:

Audio input jack wiring:
5-Pin Input Jack Wiring
PIN 1 Shield (ground) for positive biased electret
lavaliere microphones. Shield (ground) for dy-
namic 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.
It is actually a good idea to turn the gain up to maximum
and listen for distortion or compression to get a feel for
how much headroom is available.
Signal Level -20 LED -10 LED
Less than -20 dB O O
-20 dB to -10 dB Green O
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 db Red Red
Note: Dierent voices will usually require dierent gain settings,
so check this adjustment as each new person uses the system.
If several dierent people will be using the transmitter and there
is not time to make the adjustment for each individual, adjust it
for the loudest voice.
1) With the transmitter powered o, plug in the
microphone and make sure the connector is rmly
seated.
Warning: If the systems is powered up while
connected to a live sound system, be careful
to turn the sound system level down first or
severe feedback can occur.
2) Place the transmitter in Standby Mode or turn it on
for normal use.
3) Position the microphone in the location where it
will be used in actual operation.
4) Observe the Modulation LEDs while speaking or
singing into the microphone at the same voice level
that will be used during operation. While holding
the AUDIO button, press the UP or DOWN arrow
buttons until the both the -20 and -10 LEDs glow
green, with the -20 LED occasionally ickering red.
This will maximize the signal to noise ratio of the
system with full modulation and provide subtle lim-
iting to prevent overload and audible compression.
5) If the unit was set up in Standby Mode, it will be
necessary to turn the transmitter o, then power it
up again in normal operation so the RF output will
be on. Then the other components in the sound or
recording system can be adjusted.
Locking or Unlocking the Controls
Control Panel Locked
The Lock mode protects the
transmitter from accidental
changes to its settings.
Simultaneously press both the
Up and Down arrow buttons
to start the countdown timer. When the timer reaches
zero, “Loc” is displayed and the controls are locked. Set-
tings can be reviewed but not changed.
Once the transmitter is locked, it cannot be unlocked or
powered o using the buttons. The only ways to unlock
a locked transmitter are to remove the battery or unlock it
using the remote control. The remote control will work only
if the transmitter was previously congured to respond
to the remote control. The unit will always power up in
“unlocked” mode.
