Eliminating RF-Induced Microphone Noise
Using older, balanced microphones with the A10 Digital Wireless System can lead to unwanted noise. Although the inputs on the A10 System are fully protected from radio frequency interference, older microphones themselves are sensitive to RF. Here are a few solutions to remove the unwanted noise being picked up by your older microphone:
Sending your older microphone back to the manufacturer for updating will eliminate this issue.
Using the Audio Limited AC-BALXLR-4, a new Lemo-to-XLRF cable, will keep the interfering signal from entering your microphone.* This black-capped XLR cable is an improvement over the previous blue-capped model.
In the case that another cable is plugged in between the microphone and the AC-BALXLR-4, Audio Limited also offers the A-FILTER, an accessory PC board that can be soldered onto the female end of a straight XLR cable. When the XLR containing the A-FILTER is connected directly to the microphone, it reduces incoming radio frequencies. Both the A-FILTER and AC-BALXLR-4 offer a ~40 dB attenuation of unwanted RF signals entering the microphone. The A-FILTER is not compatible with the AC-BALXLR, AC-BALXLR-2, AC-BALXLR-3 and AC-BALXLR-4.
Always keep the mic cable as far away from the antenna as possible.
Use the lowest RF output level possible. The A10-TX has excellent RF range, and for many applications, 10 mW or 20 mW is sufficient. For example, if the RF is only traveling a few feet to receivers in a bag, 10 mW works well.
* Note: in the Audio Limited testing, this cable filters RF well for all microphones except for older MKH40s.
