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.
