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.Place a fresh 9-volt alkaline battery (not supplied) into your UT-5 or UH-5 transmitter, taking care to observe the polarity markings. We recommend the Duracell MN 1604 type or equivalent. We do not recommend the use of rechargeable Ni-Cad batteries because they do not supply adequate current for any significant time period. For the moment, leave the transmitter turned off.
3.Make the physical cable connections between the output of your UR-5 or UR-5D receiver (using either the balanced or unbalanced jacks)* and the input of your amplifier or mixer. If you are using professional (+4) equipment, the balanced jack is preferable since it will deliver an electromagnetically cleaner signal. Leave the amplifier (and/or mixer) off at this time.
4.Connect the supplied 3-pin “EEC” plug into the UR-5 or UR-5D rear panel AC connector and plug the other end into any grounded AC socket.
5.Turn the AF Level knob on the UR-5 receiver (or both AF Level knobs on the UR-5D receiver) completely counterclockwise (to the “0” position) and depress the power switch to turn the unit on. The display section will light up.
6.Before utilizing the UR-5 or UR-5D Group and Channel knobs to select a frequency, determine how many transmitters and receivers you will be using in one location. As shown in the chart on page 24, Groups
0through 8 provide seven available Channels each (0 through 6), while Group 9 provides eleven available Channels (0 through 9, plus Group 7, Channel 5). When two or more transmitters and receivers are being
*If required, both the balanced and unbalanced outputs can be used simultaneously.
