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. Every wireless system consists of at least two[...]

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. A built-in computer chip then continu- ously scans the two receivers and [...]

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. This makes our UHF Synth Sys[...]

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). • Tuned coaxial ante[...]

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. Third-party receiver antennas should not be substitut- ed — use only the antennas provi[...]

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. A computer chip inside the receiver constantly scan[...]

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. 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 minimu[...]

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. Note that turning this off does not turn off the transmitter power — it is simply a way to te[...]

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 [...]

17 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 whic[...]

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. 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 an[...]

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 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[...]

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. dbx ® is a companding system; that is, the signal being transmitted has its dynamic range c[...]

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. If the answer to any of these questions is “ no, ” you ?[...]

If you ’ re using a mi[...]

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.

Use the antennas provided with your Samson UHF receiver, or, if unavailable, substitute the following anten- nas only: Samson Part Number ANT 800 . Third-party antennas should not be substituted. These antenna mountings a[...]

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. The AC outlet used for powering the DA-5L must be grounded. See the “ [...]

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. Turn off the power to your audio system and all wireless components. 2. Mount a tune[...]

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. 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 c[...]

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. If the DA-5L[...]
