Receiver/Transmitter ASC™ IR Sync Manual Programming

To manually program the pre-selected Group/Channel (frequency) from the receiver to the transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37,

44)6-12” away from the receiver’s IR WINDOW (4). Press the MENU BUTTON (18) four times to the IR Screen Display and then press the UP BUTTON (16) to start IR programming. The flashing IR INDICATOR (10) icon indicates IR transmis- sion is in progress. When the synchronization is completed successfully (usually in less than 2 seconds), the RF INDICATOR (8) and the diversity A or B INDICA- TOR (9) on the receiver will display, indicating that the IR linking is completed. The LCD DISPLAY SCREEN (5) will show the selected channel. If the UP button is not pressed during the two seconds of active data transfer, the IR INDICATOR (10) will not flash, the LCD Display will revert to the main menu, the receiver will not link to the transmitter, and the transmitter’s previously programmed channel remains unchanged.

Instructions for Setup of Simultaneous Multichannel Operation

This U-800 receiver is capable of finding an open channel with its autoscan capabil- ity. This built-in feature is a quick, convenient way to set up many wireless systems at the same location for simultaneous multichannel operation.

If you are using multiple transmitters at the same location, set up the first transmitter and leave it ON and keep 10 feet away from the receivers and 1 foot away from transmitter to transmitter. This avoids possible duplicate selection of the same channel as already selected for the first receiver. Then start the autoscan function on the second receiver. Repeat this procedure for all receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform a range walk test in the location these systems will be used in to check for potential crosstalk interference in this application.

If you are not satisfied with any of the channels scanned, repeat the autoscan proce- dure for that receiver again anytime for finding another free channel.

This process can be simplified if you select channels within Factory SELECTED Groups 11 to1A, as the channels within those groups are mutually compatible (unless there is outside interference on any of the selected frequencies). If there is any such interfer- ence in your location, select as many channels as you can using these 10 groups and then select additional open channels as needed (depending on number of systems to be operated simultaneously) from Groups 1B to 1F. As noted above all these groups will retain in memory the previously selected channels for that group for easy setup subsequently in that same location.

U-800 specifications

The Nady Systems U-800 is a professional-grade wireless vocal microphone system designed for performers and speakers who demand clear sound and reliability. With advanced features and robust performance, the U-800 stands out in the crowded market of wireless audio equipment.

One of the key features of the Nady Systems U-800 is its UHF frequency range. Operating within the ultra-high frequency spectrum, this system provides a stable and interference-free signal. This is critical for live performances, as it minimizes the chances of audio dropouts or disruptions, ensuring that artists can deliver their best without technical difficulties.

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.

In summary, the Nady Systems U-800 combines professional audio quality with user-friendly features, making it a reliable choice for musicians, entertainers, and speakers. Its UHF operation, dual-channel capability, excellent sound quality, and long battery life position the U-800 as a leading solution in the realm of wireless microphone systems. Whether for stage performances or public speaking events, the U-800 ensures that every word and note is transmitted with clarity and precision.
