Using an APS UR module and UHF Transmitter(s)...
The APS UR receiver module features 63 user-selectable frequecies
within the 793-806MHz range. After installing the module (page 2) you
will have to attach the antenna and position it as close to vertical as pos-
sible. You will then select the frequency you wish to use following the
procedure below. The volume control on the module adjusts the input
volume of that particular module. Try to keep it set near its mid point for
best performance.
Frequency Selection
The group knob (GR) allows you to select any of seven frequency
groups (numbered from 0-6). The channel knob (CH) allows you to
select any of nine frequency channels (numbered 0-8) within the
selected group. Any receiver/transmitter pair must be on the same
group and frequency to operate properly. Be sure that both the trans-
mitter and the receiver are OFF before selecting/changing the fre-
quency.
When using more than one system, all receivers and transmitters
must be set to the same group to avoid intermodulation distortion
while all transmitter/receiver pair must be on different frequencies.
To change the frequency that a transmitter/receiver pair is already set
on YOU MUST FIRST TURN OFF BOTH THE TRANSMITTER AND
RECEIVER (SPEAKER)!
UHF Transmitters ...
The 51HT is a handheld microphone transmitter with 63 on-board user
selectable UHF frequencies. Ideal for all vocal applications.
(1) To install batteries, turn the bottom half of the mic case counter-
clockwise until it is completely off. Insert two fresh alkaline “AA”
batteries (2) into the compartment. Make sure battery polarity is correct.
(3) Frequency select
The group knob allows you to select any of seven frequency groups

(4) Power and Audio switches
The power “On/Off” switch enables
and disables all transmitter functions
while the Audio “On/Off” switch turns
just the transmitter’s Audio signal on
and off. Switching the Audio to “Off”
will cause the receiver to mute using
the tone squelch circuitry in the
receiver. This allows the microphone
to be handled with no noise. The “Phantom” switch allows the 51XT to
provide 5V to power electret condenser microphones.
(5) Audio input LEVEL control
This enables you to adjust the input level of the microphone. Turn
clockwise to increase, or counterclockwise to decrease the input level.
A small screwdriver is supplied to make adjustments.
(6) LED INDICATORS
The POWER LED turns green when power is turned “On” or red if
battery level is low. If this LED lights up red replace the battery.
The AF PEAK LED lights up if the input level is set to high, indicating
the onset of distortion. Lower the input level so that the AF PEAK LED
lights only occasionally.
To plug the 51XT onto a microphone (low impedance with XRL connec-
tor) first make certain the locking-ring is turned fully up (rotate counter-
clockwise). Then plug the 51XT fully into the microphones XLR connec-
tor and tighten by rotating the ring fully down (clockwise).
