Introduction thank you for selecting the lectrosonics um195 belt-pack transmitter. The um195 combines over 80 years of engineering experience with the very latest components, in a design that addresses the most demanding professional applications. The design of the um195 was the direct result of num...

General technical description the um195 transmitters are comprised of a number of functional sub-systems as shown in the block diagram below. The 195 system uses 75khz wide deviation for an extremely high signal to noise ratio. The transmitter circuits are all regulated to allow full output power fr...

The signal to noise ratio of the 195 system is high enough to preclude the need for conventional pre-emphasis (hf boost) in the transmitter and de-emphasis (hf roll off) in the receiver. Pre-emphasis and de-emphasis in an fm radio system usually provides about a 10db improvement in the signal to noi...

Controls and functions (cont’d) since the internal circuits are all tightly regulated and the rf output stage has a separate discrete regulator, the transmitter will continue to operate to a battery voltage of 6.5 volts. From 6.5 volts to 6 volts, the transmitter will still operate, but with degrade...

Battery installation the transmitter is powered by a standard alkaline 9 volt battery. It is important that you use only an alkaline battery for longest life. Standard zinc-carbon batteries marked "heavy-duty" or "long-lasting" are not adequate. Ni-cad rechargeable batteries will only provide 2 hour...

Troubleshooting before going through the following chart, be sure that you have a good battery in the transmitter. It is important that you follow these steps in the sequence listed. Symptom possible cause transmitter battery led off 1) battery is inserted backwards. 2) battery is dead. No transmitt...
