equipment to be completely satisfactory, please immediately contact your Vega
dealer or the Vega factory.

Should service ever be required, remember your authorized Vega service dealer
knows your equipment best. They have the training and test equipment necessary to
restore your equipment to its peak performance. Please feel free to contact either
your authorized Vega dealer or the Vega factory for information or assistance at any
time.

Quick Start

See below for a description of transmitter controls and the next page for setup. If this
is the first time you are setting up a wireless system, carefully read all manuals
furnished with your equipment to ensure optimal performance.

2

Turn the transmitter Power “P” on and
Microphone “M” on by sliding the switches
toward the dots.

4

In the area covered by the wireless system,
verify the receiver is receiving by observing
its indicators (see receiver instructions for
details).

5

Adjust mixer/preamp/amplifier to its normal
setting. Speak into mic. If necessary, adjust

receiver's audio output level until wireless system
volume matches wired system volume (see
receiver instructions for details).

With a small screwdriver, adjust transmitter
mic level so the receiver's “AUDIO LEVEL”
LED flashes only when speaking very loudly.

If it flashes frequently, turn it counterclockwise. If
it doesn't flash at all, turn it clockwise.

6

“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. T­680s 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 Seriesmics 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.
