UH-800 HANDHELD MICROPHONE TRANSMITTER (HT)

Setting up the UH-800 Transmitter

The UH-800 requires two AA alkaline or NiMH batteries to operate (do not mix types). Installing batteries by unscrewing counterclockwise the BATTERY COVER

(29)and slide down, exposing the BATTERY COMPACTMENT (32). Insert two fresh AA BATTERIES (31), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed clockwise com- pletely. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the batteries after every 6-8 hours of use.

Powering the UH-800 Transmitter On/Off

Turn on the UH-800 by sliding the AUDIO SWITCH (36) to the OFF position first. Then slide the POWER SWITCH (35) to the ON position. The POWER ON LED

(33)will stay on, indicating that the transmitter is now on. The BATTERY LED (34) will stay off, indicating usable battery strength. In the case of a dead or low battery, the low battery LED will light red continuously, indicating that the batteries should be replaced with fresh ones.

To preserve battery life, turn the transmitter off when not in use. To turn the transmitter off, slide the RF POWER (35) switch to the OFF position. The POWER ON LED

(33)is not lit up, indicating the unit is off. The MUTE ICON (6) on the receiver should be on, muting the audio out.

At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Group 11, Channel 01.

For optimum performance, an AUDIO INPUT LEVEL (30) is provided. Adjust the gain by turning the control with a small screwdriver. It is recommended that the level be set at about 1/2 maximum. Experiment and set for maximum possible gain with- out audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and it is not recommended.)

The microphone is now ready to use. The diversity A/B INDICATORS (9) on the U-800 receiver should now be on, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE (36) to the ON position. The MUTE ICON (6) on receiver should be off. Adjust the volume of the receiver as per the Au- dio Output Microphone Connection section of the above U-800 receiver instructions.

The U-800 is equipped with a dual-channel receiver that allows for simultaneous operation of two microphones. This flexibility is ideal for duets, panel discussions, or any situation where multiple vocalists or speakers are needed. Each channel has its own volume control, providing users with the ability to balance sound levels seamlessly.

Signal strength is another vital characteristic of the U-800, featuring a dynamic range that offers clear high frequencies and deep lows, contributing to an overall rich sound quality. The system also employs advanced companding technology, which reduces unwanted noise and enhances the clarity of the audio being transmitted.

The microphone itself is lightweight and ergonomically designed for comfortable use, making it suitable for long performances or presentations. Additionally, it features a cardioid pickup pattern that helps isolate the desired sound source while minimizing background noise. This is particularly beneficial in live settings where crowd noise or other distractions may be present.

Battery life is a crucial aspect of any wireless system, and the U-800 does not disappoint. With efficient power management, the system offers extended battery life, allowing users to perform longer without the worry of battery depletion. It is also designed for quick and easy setup, with an intuitive interface that makes it accessible even for those who may be new to wireless systems.
