Intr oduction 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.
Intr oduction 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.
System Featur es 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.
System Featur es • 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).
Guided T our - UR-5/UR-5D Fr ont Panel 1: Power switch - Use this to turn the main power on and off. When the receiver is on, the display section (see #5 on the next page) is lit. 2: Antenna A and B mountings - Connect the supplied antennas to these mountings.
Guided T our - UR-5/UR-5D Fr ont Panel 5: Display section - Shows you information about the current status of your receiver. 5a: “A”/“B” LEDs - When signal is being received, one of these LEDs (which shows you whether the “ A ” or “ B ” channel is currently being used) will be lit.
Guided T our - UR-5/UR-5D Fr ont Panel 5e: AF (Audio Frequency) Level display - This “ ladder ” display (simi- lar to the VU bar meter used on audio devices) indicates the presence of audio signal.
8 Guided T our - UR-5/UR-5D Rear Panel 1: AC input - Connect the supplied standard 3-pin “ EEC ” plug here. The UR-5 and UR-5D both contain automatic current and voltage sensing circuitry and so can accept any mains current from 100 - 250 volts without the need to set a selector switch.
9 Guided T our - UR-5/UR-5D Rear Panel 3: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4 ” jack when connecting the UR-5 or UR-5D to consumer (-10) audio equipment.

12 Guided T our - UT-5 6: Group selector - Use the supplied plastic screwdriver to set this to the desired Group (this must match the Group setting of the receiver — see the “ Setting Up and Using the UHF Synth System ” section on page 16 for more information).

15 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.
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.

18 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.
19 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 r.
20 About dbx ® Noise Reduction and T one 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.
21 Tr ouble-shooting Pr oblem: 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 sug- gestions to identify the problem.
22 Tr ouble-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.
23 Tr ouble-shooting Pr oblem: Sound fades as per for mer moves ar ound (sound dr opout) 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.

28 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.
29 Guided T our - DA-5L Fr ont Panel 1: Antenna A and B mountings - Connect a pair of tuned coaxial antennas to these mountings. Use the antennas provided with your Samson UHF receiver, or, if unavailable, substitute the following anten- nas only: Samson Part Number ANT 800 .
30 Guided T our - DA-5L Rear Panel 1: AC input - Connect the supplied standard 3-pin “ EEC ” plug here. The DA-5L contains an automatic current and voltage sensing circuitry and so can accept any mains current from 100 - 250 volts without the need to set a selector switch.
31 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.
32 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.
33 DA-5L Gr ounding T echniques 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.
34 Glossar y of T er ms 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.
35 Glossar y of T er ms 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.
