OPEN SERVO - 240 Introduction Congratulations on purchasing the Samson UHF Synthesized True Diversity Wireless System! Although this product is designed for easy operation, we suggest 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. Every wireless system consists of at least two components—a transmit- ter and a receiver. The Samson UHF Synth System you have purchased contains either our UT-5 belt-pack transmit

Introduction The concept behind a “true diversity” wireless system is that a single chassis houses two discrete receivers (called “channel A” and “channel B”) instead of one, with both tuned to the same frequency but with each using an independent antenna. A built-in computer chip then continu- ously scans the two receivers and determines which one has the clear- est and strongest reception, automatically (and silently) switching to that channel. This allows you to maintain the wireless commun

System Features The Samson UHF Synthesized True Diversity System utilizes state-of- the-art technology in wireless communications. Here are some of its main features: • 74 available channels organized in 10 different groups in both the receiver and transmitter, with up to 11 channels available for simulta- neous use. This makes our UHF Synth System the ideal choice in multi-user environments such as stage productions and live band performance. It is also specifically suited for systems that t

System Features • The UT-5 and UH-5 transmitters both accept standard 9-volt alkaline batteries, and the UR-5 and UR-5D receivers can accept any AC power voltage from 100 - 250 volts, without the need to change a voltage selector switch (our special current and voltage sensing circuitry does the job automatically for you). • Tuned coaxial antennas are included, with options for rear-mounting or remoting if extended range is required. • The UR-5D dual receiver actually contains two separate true

A computer chip inside the receiver constantly scans the two and automatically selects whichever is receiving the strongest, clearest signal. This “true diversity” switching is completely inaudible, but it effectively i

When all five segments are lit, the outgoing signal is at maximum strength; when only the left-most segment is lit, the outgoing signal is at minimum strength. If no segments are lit, little or no signal is being output; see the “Trouble-shooting” section on page 21 for more details. 6: AF (Audio Fre

Guided Tour - UH-5 7: Audio off-on switch - When set to the “on” position, audio signal is transmitted. When set to the “off” position, the audio signal is muted. Because the carrier signal remains during muting, no “pop” or “thud” will be heard. Note that turning this off does not turn off the transmitter power—it is simply a way to temporarily mute the transmission of audio signal. If you don’t plan on using the transmitter for extended periods, turn off the transmitter power by using the

OPEN OPEN Setting Up and Using the UHF Synth System The general procedure for setting up and using your UHF Synth System is basically the same regardless of the particular components you are using (i.e. UT-5 or UH-5; UR-5 or UR-5D): 1. Remove all packing materials (save them in case of need for future service) and mount the supplied “A” and “B” antennas to your receiver by inserting the BNC connector and twisting clockwise until snug.

Place a fresh 9-volt alkaline battery (not supplied) into your UT-5 or UH-5 transmitter, taking care to obser

Setting Up and Using the UHF Synth System used at the same location, all devices must be set to the same Group (though each will use its own Channel) or intermodulation noise may occur. If you are using the UR-5D receiver for the reception of a stereo signal (or for the reception of two simultaneous monophonic signals), both sides (Receiver 1 and Receiver 2) must be set to the same Group. If you are only using a single transmitter and receiver, you can select any Group and available Channel wi
