Page 3: Introduction
Introduction Congratulations on purchasing the Samson UHF Series True Diversity System! Although this product is designed for easy operation, we sug- gest you take some time out first to go through these pages so you can fully understand how we’ve implemented a number of unique features. - Page 4 Finally, the provision of dbx® noise reduction* produces crystal-clear sound with minimized background noise and hiss. Your UHF Series True Diversity System may also optionally include a DA-5H UHF Antenna Distribution Amplifier. For more information on this device, see pages 26 - 31.

Page 5: System Features
System Features The Samson UHF Series True Diversity System utilizes state-of-the-art technology in wireless communications. Here are some of its main features: • The use of the UHF (Ultra High Frequency) band as opposed to VHF (Very High Frequency). This yields better signal-to-noise ratio and improved frequency response—in plain English, superior sound... - Page 6 System Features • The UT-4 belt-pack transmitter is extremely light-weight (less than 4 ounces with a 9-volt battery installed) and is suited for a wide range of lavalier microphones, headset microphones and instruments such as electric guitar and bass. It also provides phantom powering, making it compatible with professional condenser lavalier and headset microphones.

Page 28: About The Da-5H Uhf Antenna Distribution Amplifier
* Note that, even though the DA-5H allows multiple receiver antenna inputs to be shared, each receiver (and accompanying transmitter) in your UHF Series True Diversity wireless system must still be tuned to a discrete channel for multi-user operation. -

Page 33: Da-5H Grounding Techniques
DA-5H Grounding Techniques The DA-5H contains a switching power supply that will add an audible hum to your audio signal if the unit is not plugged into a properly grounded three-pin AC socket. Unless you’re using a “star ground network” (see below), you must not use an adapter to lift the ground from the DA-5H AC cable. -
Page 34: Glossary Of Terms
Noise Reduction - A process by which the level of extraneous noise or hiss in a signal is reduced considerably. The Samson UHF Series system utilizes the dbx® system of noise reduction. - Page 35 Glossary of Terms Receiver - A component that receives a modulated radio signal and restores the original audible signal by utilizing demodulation. RF - Short for “Radio Frequency.” Transmitter - A component that transmits an audible signal by causing it to modulate a high-frequency inaudible carrier signal. True Diversity - A wireless reception system by which a single chassis houses two discrete receivers, with both tuned to the same frequency but with each using an independent antenna.
