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 transmitter and a receiver.
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 continuously scans the two receivers and determines which one has the clearest and strongest reception, automatically (and silently) switching to that channel.
System Features The Samson UHF Synthesized True Diversity System utilizes state-ofthe-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 simultaneous use. This makes our UHF Synth System the ideal choice in multi-user environments such as stage productions and live band performance.
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.

A computer chip inside the receiver constantly scans the two and automatically selects whichever is receiving the strongest, clearest signal.
Guided Tour - UR-5/UR-5D Front Panel 5e: AF (Audio Frequency) Level display - This “ladder” display (similar to the VU bar meter used on audio devices) indicates the presence of audio signal. 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.

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.
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.

Setting Up and Using the UHF Synth System tions) are more prone to feedback problems than unidirectional (cardioid or supercardioid) ones; in general, you can avoid feedback by taking care not to use any microphone directly in front of a PA speaker (if this is unavoidable, you can try using an equalizer to attenuate those high frequencies which are causing the feedback “squealing”). 2.
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.
Setting Up and Using the UHF Synth System segments should light up. If you are using the UT-5 transmitter with a connected instrument, play the instrument at normal performance level while slowly raising the equivalent AF Level knob on the receiver to a level of approximately “8”; again, one or more segments in the AF Level display should light up as you do so. 9. Temporarily mute the audio signal by placing the UT-5 or UH-5 Audio switch to the “off” position.
About dbx® Noise Reduction and Tone Squelch About dbx® Noise Reduction: All the components in the Samson UHF Synth System utilize dbx® noise reduction so as to ensure the highest fidelity sound with an absolute minimum of background noise and hiss.
Trouble-shooting Problem: No sound Solution: When working correctly, both the RF Level and AF Level meter displays in the UR-5 or UR-5D receiver should be lit when signal is present. If they aren’t, follow these step-by-step troubleshooting suggestions to identify the problem. If the answer to any of these questions is “no,” you’ve probably located the difficulty. If both the RF Level and AF Level displays are lit, you can skip ahead to questions 9, 10 and 11. 1.
Trouble-shooting 8. Is the “Available” LED on the receiver lit and is the “Unavailable” LED on the transmitter off? 9. Is the cable connection between the receiver output and your mixer/amplifier input secure? 10. Is your mixer/amplifier system powered on and is its level control or fader up and unmuted? 11. If you’re using a mixer, are all channels out of solo mode? If the answer to all these questions is “yes” and you still hear no sound, call Samson Technical Support at 1-800-372-6766.
Trouble-shooting Problem: Sound fades as performer moves around (sound dropout) Solution: Try relocating the transmitter and/or receiver. In general, it’s best to minimize the distance between the two and also to try to keep a clear “line of sight,” so that the person wearing or using the transmitter can always see the receiver.

About The DA-5L UHF Antenna Distribution Amplifier The Samson DA-5L UHF Antenna Distribution Amplifier is an optional component of the UHF Synthesized System. The DA-5L allows up to four UR-5 or UR-5D UHF receivers to share the same pair of antennas.* It facilitates faster, more compact setups by reducing the number of antennas from eight to two while increasing the transmission range by adding 6 dB of RF gain for a stronger, quieter signal.

Setting Up and Using the DA-5L The basic procedure for setting up and using your DA-5L UHF Antenna Distribution Amplifier takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and mount the DA-5L into your rack. Turn off the power to your audio system and all wireless components. 2.
Setting Up and Using the DA-5L If necessary, longer runs of standard low-capacitance (50-ohm) coaxial cabling with BNC connectors can be substituted for the supplied cables. Note that, even though the DA-5L allows receiver antenna inputs to be shared, each receiver (and accompanying transmitter) in your system must still be tuned to a discrete channel for multi-user operation. 4.
DA-5L Grounding Techniques The DA-5L 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-5L AC cable.
Glossary of Terms Audible - A sound that we can hear, generally in the 20 Hz - 20 kHz frequency range. BNC - Short for “British Naval Connector.” A standard RF antenna connector used by many wireless receivers, including the Samson UR-5 and UR-5D. Carrier - An inaudible high-frequency radio signal that is continuously modulated by an audible signal (it therefore is said to “carry” the audible signal). Channel - In wireless transmission, refers to a particular radio frequency.
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 Synth system utilizes the dbx® system of noise reduction. 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.
