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. Third-party antennas should not be substituted. These antenna mountings are phantom powered; take care not to short them. See the section in this manual entitled “Setting Up and Using the DA-5L” (on page 31) for information about antenna installation and positioning.

2:“Power” LED - This is lit whenever the DA-5L is powered on.

3:Power switch - Use this to turn the main power on and off. When the DA-5L is on, the “Power” LED (see #2 above) will be lit.

A built-incomputer 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 communication link over a much broader area range than would be allowed by a single receiver and also virtually eliminates interference and phase cancella- tion problems. In addition, our special circuitry, which utilizes the UHF Ultra High Frequency band, delivers the highest-qualitysound available in any wireless system. Finally, the provision of dbx noise reduction* produces crystal-clearsound with minimized background noise and hiss. Your UHF Synthesized True Diversity System may also optionally include a DA-5LUHF Antenna Distribution Amplifier.

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-itis 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 power on-offswitch see #1 on the previous page. As described on page 20 of this manual, setting the UT-5Audio switch to the “on” position operates a tone squelch feature by causing a 38.4 kHz signal to be added to the carrier. The illuminated word “MUTE” in the UR-5and UR-5Ddisplay is a visual representation of the absence of this 38.4 kHz signal. When “MUTE” is lit, either the transmitter Audio switch is in the “off” position or the currently selected Group and Channel do not match that of the transmitterSetting 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” Setting Up and Using the UHF Synth System7.Turn on the power to the UT-5or UH-5transmitter using its Power on-offswitch and observe the RF Level display in the UR-5or UR-5Dreceiver all segments should light up. When first setting up the UHF Synth System in a new environment, it’s always a good idea to do a walkaround while experimenting with different Group and Channel settings-youmay find that some cause more RF Level segments to light up than others the more segments light, the stronger the signal. Always pick the Group that has the greatest number of clear Channels and the Channel providing the strongest signal. Note that whenever a new channel is selected, it takes approximately five seconds for audio signal to be passed through to the receiver outputs Setting Up and Using the UHF Synth Systemsegments should light up. If you are using the UT-5transmitter 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 Setting Up and Using the UHF Synth SystemAbout dbx Noise Reduction About dbx Noise Reduction and Tone SquelchAbout Tone Squelch Problem No sound Trouble-shooting8.Is the “Available” LED on the receiver lit and is the “Unavailable” LED on the transmitter off? Trouble-shootingSolution 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. If necessary, try relocating the receiver antennas to either the rear panel contact Samson Technologies for details about our rear panel mounting kit or remote them some distance from the receiver, using 50 ohm coaxial cable suitable for up to 1 gigaHertz bandwidth the lower the capacitance of the cable, the further you can remote the antennas Trouble-shootingG R O U P UHF Synthesized Frequency ChartSAMSON UHF SYNTHESIZED FREQUENCY CHART C H A N N E LGC-1 MC-1 UT-5 Multi-pinLavalier Wiring Guide+9 VDC UT-5 Multi-PinWiring ChartManufacturer Model No.Pin 1Pin Pin InformationHi-Z UT-5 Multi-PinWiring ChartPin 3Pin 4Pin 5Pin GroundAbout The DA-5LUHF Antenna Distribution Amplifier Guided Tour - DA-5LFront Panel Guided Tour - DA-5LRear Panel Third-partyantennas should not be substituted Setting Up and Using the DA-5L4.Connect the supplied 3-pin“EEC” Setting Up and Using the DA-5LDA-5LGrounding Techniques Glossary of Terms RF - Short for “Radio Frequency.” Glossary of TermsTransmitter RF SpecificationsTransmitter Audio Receiver SpecificationsDA-5L FCC Rules and Regulations
