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. The transmitters are not compatible with other manufacturers' receivers.
T-680 Series mics work in the 494 to 608 MHz and 614 to 806 MHz UHF range. The exact frequency is marked on the data label inside the transmitter's battery compartment. If the transmitter and receiver frequencies are not precisely the same, the frequency of one of the units must be changed. It's advisable to return both units to the factory or authorized service location when changing frequencies, to ensure the best results. Because of the very high performance of these units and the specialized test equipment required to adjust them properly, users should not try to change frequency themselves.
If two or more systems are used at the same location, proper frequency selection and spacing are required to avoid possible interference.
Vega offers a free frequency-coordination service for purchasers of its equipment. Frequencies are selected by computer to avoid any possible interference from other wireless systems and broadcast stations. To take advantage of this free service, contact the Vega factory or your local sales representative (phone number on last page of this manual).
The T-680 Series professional handheld transmitters are self-contained units and require only a battery and a compatible receiver for operation. Individual models in the T-680 Series each use different types of microphone elements, leading to some differences in physical appearance between the various models. However, all transmitters in this series are functionally equivalent, and the operation instructions below and other information in this manual are applicable to all models.
Because of the acoustic characteristics of the various types of microphone elements, individual models in this series may sound significantly different from other models. These differences are entirely due to the microphone element; all models offer identical performance, otherwise.
