Microphone Basics Microphone Position The UHF-3800 is ideal for close-up vocals and can be held in the hand or mounted on a mic stand.The most common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a matter of personal taste, there is no one "correct" microphone position. Proximity Effect When the sound source is less than 1/4 in.
UHF-3800 & Stage Monitor/P.A. Loundspeakers If you will be using the UHF-3800 with stage monitors and/or P.A. system, try the following: • Place the stage monitor directly behind the microphone. • Locate the P.A. loudspeakers so that they point away from the rear of the microphone. (With the speakers located in these positions, the possibility of feedback is greatly reduced). • Always check the stage setup before a performance to ensure optimum placement of microphone and monitors.
Before Getting Started Before starting any installation procedures, it is recommend to completely unpack all the package contents. The original packaging should be kept in the event that re-shipping is needed.

Getting Connected System Connection 1. Connect the AC POWER ADAPTER to the UHF-3800 receiver's POWER INPUT connector; then plugging the ADAPTER into a compatible AC electrical outlet. 2. Connect the UHF-3800s receiver to a sound system, mixer or amplifier's microphone input(s) with either one ¼" output jack for a mixed channel output, or both XLR output jacks for separate output.
Operations 1. Press the POWER button on the UHF-3800 receiver's front panel. The power LED on the receiver will glow BLUE. 2. Adjust the receive's VOLUME controls to approximately 50%. 3. Switch the microphone's POWER BUTTONS to the ON positions. 4. Talk or sing into the microphones. During normal operation, the RF/AF signal LED's will light RED when a microphone is being used. 5. Adjust the receiver's VOLUME controls until the output levels are balanced with eachother and other possible source output i.e.
Tips for Achieving Optimum Performance Recognizing Interference The ways of recognizing the type of interference present are observing the RF/AF LED indications and carefully listening to the audio output. A set of headphones can be a useful tool in isolating and analyzing interference problems. With headphones it is easier to listen to one wireless channel at a time, even when the system is in use. Below are some common interference descriptions.
Tips for Achieving Optimum Performance (cont.) If none of the descriptions matches your particular problem, or the information is unclear, see the "Avoiding Basic Problems/UHF Frequency Conflicts" sections below. Your authorized dealer may also be able to offer assistance and might be familiar with any unusual local conditions that could be affecting the problem. If your dealer is not able to assist, owners of VocoPro equipment can obtain telephone support at: 800-678-5348 9A-5P M-F Pacific Time.
Troubleshooting Problems No sound output, RF/AF LED(s) not glowing. Solutions • Make sure the microphone and receiver power switches and receiver are set to the ON position. • Check microphone batteries to ensure that they are providing sufficient power. Replace battery if necessary. • Check receiver's AC power connection. • Make sure antennas are firmly connected and extended to an optimal position. • If necessary, reduce the distance between the microphones and receiver.
