Cerwin-Vega T-680 Microphone User Manual


 
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. This
is usually due to spurious outputs from two-way radio transmitters, adjacent-channel
leakage from TV transmitters, and, in some cases, RF noise from digital equipment
such as audio and video effects generators, computers, and other industrial
equipment that might be located near the antennas. When the wireless transmitter is
“on,” this noise is suppressed and rarely causes any difficulties. However, if the
audio channel is left “open” with the transmitter “off,” loud blasts of noise might
occur. For this reason, it is advisable to “fade” the receiver audio when the
transmitter is not in use. Changing the placement of the antennas and, in some
extreme cases, changing the operating frequency might be necessary to minimize
these problems.
Antennas/Cables
As noted in the section on antennas above, antenna placement and mounting are
vitally important. Blocking the antenna with metallic objects reduces the signal level
and might cut off the signal entirely (pattern “nulls”). If there is a coverage problem,
try moving the receiving antenna, particularly if there are nearby metallic materials.

Warranty does not extend to damage due to improper repairs, finish or appearance items,
malfunction due to abuse or operation under other than the specified conditions, nor to
