Frequenc y Modulation (FM) Tec hnology Overview
Frequenc y modula tion or (FM) is a mea ns of tra nsmitting a udio using elec troma gnetic wa ves. This sa me
tec hnology is used by loc a l FM ra dio sta tions to broa dc a st music . FM signa ls c a n tra vel through most ba rriers
– wa lls, floors, a nd c eilings. The dista nc e a signa l tra vels ha s ma ny different va ria bles suc h a s Ra dio Frequenc y
(RF) output power, the type a nd pla c ement of the a ntenna , a nd the broa dc a sted frequenc y. Unlike infra red,
FM tra nsmission a re not sec ure. This ena bles a rec eiver to tra vel further dista nc es from the sourc e. This sec tion of
the ma nua l will help you design a system tha t will get the best ra nge a nd lea st a mount of interferenc e.

Selecting Transmitting Frequencies
Use this sec tion of the guide to c hoose the c ha nnel settings for the tra nsmitter a nd rec eivers.
Find transmission channel(s)
The goa l is to find a tra nsmission c ha nnel(s) tha t is free from interferenc e. Interferenc e c omes from
tra nsmitters a nd other outside FM signa ls.
Listen’s LT-803-072 offers 3 different channels to choose from
With 3 different c ha nnels to c hoose from, the c ha nc e of finding a n interferenc e free c ha nnel is inc rea sed.
The best wa y to c hec k for interferenc e is to turn the LR-200-072 on a nd listen to ea c h c ha nnel. Tra nsmit on the

Maximizing Transmission Range
For proper a nd dependa ble opera tion, Listen rec eivers need to rec eive a strong a nd c onsistent signa l from the
origina ting tra nsmitter. The following stra tegies should be used to ma ximize this signa l:
Transmitting antenna
When designing a nd insta lling your system, keep in mind tha t the loc a tion of both the tra nsmitting a nd
rec eiving a ntenna s is c ritic a l to ma ximize broa dc a st ra nge. Minimize the dista nc e a nd remove a ny obstruc tions
between the tra nsmitting a nd rec eiving a ntenna s. Keep tra nsmitting a nd rec eiving a ntenna s (rec eiver ea rphone

IMPORTANT: DO NOT ATTEMPT TO CHARGE ANY TYPE OF BATTERY OTHER THAN NiMH (NICKEL METAL HYDRIDE) with
your Listen equipment. Alkaline batteries may explode when c onnec ted to a c harger. Other risks of
c harging non-NiMH batteries inc lude destruc tion of property or fire.
IMPORTANT: In order to c harge NiMH batteries, the BATTERY SELECT switc h in your Listen produc t must be set to the
NiMH setting. Use a pen or small sc rewdriver to move the switc h (loc ated in the battery c ompartment)
to the proper position.
WARNING: The c ase lid MUST be open or removed while the units are c harging. The c harging proc ess generates
heat. Air ventilation is required. It is best to store your c harging c ase at room temperature away from

The LT-803-072 has no power.
Ma ke sure the 12 VDC power tra nsformer is c onnec ted to a power sourc e a nd is c onnec ted to the
ja c k ma rked “Power Input”. Ma ke sure the PWR button is pressed in.
There is no audio or the audio level is too low.
1. Ma ke sure tha t your a udio sourc e is properly c onnec ted to Input 1 a nd/or Input 2. The Input 1 or
Input 2 switc hes must be in the c orrec t position for the a ppropria te input level. For exa mple: if you
a re using the output of a mixer on Input 2, the switc h should be in the -10 dBu position. If it were to be
in the +10 dBu position, the level would be too low. Also, c hec k the Input knob to ensure it is properly
a djusted. You should be a ble to see illumina ted lights on the VU meter on Input 1 or Input 2
c orresponding with the input level of the a udio sourc e. You c a n listen to the a udio sourc e by
c onnec ting a hea dset to the front pa nel ja c k a nd a djusting the Monitor volume c ontrol.
2. If the level of a udio into the tra nsmitter is low a nd c a nnot be c orrec ted using the level input switc hes,
the a udio proc essor c a n be turned on to boost the signa l (see pa ge 28 for desc ription of Proc ess

The audio is distorted.
C hec k to ma ke sure you ha ve the input level selec t switc hes in the proper position. You ma y be
providing too muc h a udio level for the input sta ge to ha ndle.
There is hum in the audio.
Ma ke sure you ha ve properly grounded the a udio sourc e to the LT-803-072. C hec k the c onnec tions
from the a udio sourc e to the LT-803-072. If you c a n, try to use a ba la nc ed a udio sourc e - this will
reduc e the c ha nc e of c rea ting hum. C onnec t a ground wire from the LT-803-072 to ground a nd/or to
the ground of the sourc e a udio.
There is a tone.
The Test Tone button ha s been pressed (its LED light is on). Push the Test Tone button to turn off the tone.
The Audio Input 1 sounds “tinny”.
If you a re using a n unba la nc ed a udio sourc e, ma ke sure Pin 3 on the XLR or the ring on the ¼ in. plug is

C hec k to ma ke sure the rec eiver a nd the tra nsmitter a re on the sa me c ha nnel. Ma ke sure the

I c an pic k up the signal on the rec eiver, but it sounds like it’s not tuned in.
C hec k to ma ke sure the tra nsmitter a nd rec eiver a re on exa c tly the sa me c ha nnel. It’s a good idea to
loc k the c ha nnels onc e they ha ve been set. To loc k the LT-803-072, press the UP button for 3 sec onds.
There is not suffic ient range.
First ma ke sure tha t the rec eivers you a re using a re opera ting properly, then ma ke sure tha t you ha ve
a n a ntenna c onnec ted either to the top of the LT-803-072 tra nsmitter or c onnec ted to the ba c k of the
unit (but not both!). The a ntenna should be a s high a s possible a nd free of obsta c les. In a ddition, ma ke
sure you a re using the c orrec t a ntenna type for your unit. You might wa nt to use a remote a ntenna
[LA-122 Universa l Antenna Kit (72 MHz) or LA-116 C oa xia l Dipole Remote Antenna (72 MHz)] tha t c a n
be mounted on a ma st or wa ll. Try using different frequenc ies to find one with less interferenc e.

Troubleshooting
Troubleshooting
There is interferenc e in my transmission.
Ensure tha t the tra nsmitter a nd rec eivers a re on the sa me c ha nnel. Verify tha t there a re no other
tra nsmitters on the sa me c ha nnel or a c lose c ha nnel to the one exhibiting interferenc e. Try
different c ha nnels until you find a c lea r c ha nnel. Plea se c onta c t Listen for more idea s on
troubleshooting the interferenc e.
End users are adjusting the unit.
First, loc k the c ha nnel on the LT-803-072 by pressing a nd holding the c ha nnel selec t UP button for 3
sec onds. C onsider removing the Input, Mix Level a nd C ontour knobs. You c a n order a ra c k mount
kit (LA-326) from Listen whic h offers a sec urity c over tha t will limit a c c ess to the unit.
I am using another manfac tures rec eiver with the LT-803-072.
Listen’s 72 MHz equipment is c ompa tible with a ny other 72 MHz equipment.
Several transmitters are operating in the same environment.
Be sure ea c h tra nsmitter is using a sepera te frequenc y (A,E,H).
Can I have two antenna’s c onnec ted to my transmitter.
No. The LT-803-072 tra nsmitter c a n use only one a ntenna c onnec tion a t a time. You ma y c onnec t
either a top mount a ntenna through the top a ntenna port, or a remote a ntenna c onnec ted to
the BNC c onnec tion on the rea r of the unit. If multiple a ntenna s a re simulta neously c onnec ted to
both ports the tra nsmitter will ha ve extremely poor broa dc a st performa nc e a nd ra nge.
