A Word to Vega Users In selecting Vega wireless microphones, you are in the company of audio professionals worldwide. Leadership for over 30 years has made “Vega” synonymous with wireless microphones. Vega equipment provides superb sound quality, outstanding performance, and durability needed for years of successful operation.
Wireless-Microphones 3 “Walk” the coverage area to check for problems. If there is a problem, check mic batteries (fresh?); ensure antennas aren't touching each other or any metal objects. Path between transmitter and receiver must be clear for proper operation.
Compatibility T-680 Series mics are designed to work with Vega's Model 662 Series receivers. T- 680s are not necessarily compatible with other receivers, especially if not purchased together. System receivers must use DYNEX®III audio processing and use precisely the same frequencies as the transmitters.
Operating Instructions (1) Verify that the associated wireless-microphone receiver is on the exact same frequency as the T-680 Series transmitter to be used. (2) Set up, adjust, and connect the receiver as described in its instruction manual. (3) Verify that the transmitter's battery is fresh.
Antennas The receiver antenna may be the most important single component in a wireless- microphone system. However, this is the item most often overlooked in setting up a system, and is frequently the cause of quite unnecessary problems. Proper placement of the receiving antenna(s) is vitally important in any wireless-microphone system.
UHF communications antennas are also sometimes used for specialized requirements. However, such antennas are usually narrow band and must be modified to function properly in the 494 to 608 MHz and 614 to 806 MHz ranges. Contact the Vega factory or your sales representative for assistance in selecting antennas for unusual applications.
In Case of Difficulty The majority of difficulties with Vega wireless mics are not due to equipment failure. Vega equipment is fully tested before leaving the factory. In most instances, problems are due to equipment application. The following paragraphs describe the most commonly encountered application problems.
Interference Vega wireless-microphone systems have been specifically designed to reject interference. However, interfering signals might fall directly on the receiver frequency, making it impossible to avoid problems completely.
Receiver Noise Vega wireless microphone receivers are designed to be extremely sensitive. Although high-performance squelch circuits are provided, it is not unusual for the receiver squelch to open and let through audio noise when the transmitter is off.
Important: Be sure the exact return address and a description of the symptoms are enclosed inside the package with your equipment. It's also advisable to return the transmitter and receiver for a full system performance test when practical. Factory Service Center: Vega 9900 E.
