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 with a sufficiently strong signal (see #6 below). Start with Group 0 and scan through all available Channels while observing the RF Level display in the receiver. If any segments glow with the transmitter off, the selected Channel may be receiving interference and is probably unsuitable for use (one segment glowing is insignificant). Select a Group that has the greatest number of suitable Channels (that is, Channels where no segments light or glow with the transmitter off).* When you have decided which Group and Channel you wish to utilize, use the supplied plastic screwdriver to set the same Group and Channel on the appropriate UT-5 or UH-5 transmitter.
7.Turn on the power to the UT-5 or UH-5 transmitter (using its Power on-off switch) and observe the RF Level display in the UR-5 or UR-5D receiver; 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—you may 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.
8.Once you’ve settled on your Group and Channel assignments, it’s time to set the audio levels. If you are using the UH-5 transmitter or the UT-5 transmitter with a connected lavalier or headset microphone, speak or sing into the mic at a normal performance level while slowly raising the equivalent AF Level knob on the receiver to a level of approximately “8.”. Observe the receiver’s AF level display as you do so; one or more
*If your installation requires more than seven simultaneous Channels, you’ll have to use Group 9.
