Troubleshooting

Troubleshooting

There is interference in my transmission.

Ensure that the transmitter and receivers are on the same channel. Verify that there are no other transmitters on the same channel or a close channel to the one exhibiting interference. Try different channels until you find a clear channel. Please contact Listen for more ideas on troubleshooting the interference.

End users are adjusting the unit.

First, lock the channel on the LT-803-072 by pressing and holding the channel select UP button for 3 seconds. Consider removing the Input, Mix Level and Contour knobs. You can order a rack mount kit (LA-326) from Listen which offers a security cover that will limit access to the unit.

I am using another manfactures receiver with the LT-803-072.

Listen’s 72 MHz equipment is compatible with any other 72 MHz equipment.

Several transmitters are operating in the same environment.

Be sure each transmitter is using a seperate frequency (A,E,H).

Can I have two antenna’s connected to my transmitter.

No. The LT-803-072 transmitter can use only one antenna connection at a time. You may connect either a top mount antenna through the top antenna port, or a remote antenna connected to the BNC connection on the rear of the unit. If multiple antennas are simultaneously connected to both ports the transmitter will have extremely poor broadcast performance and range.
