FAQ

What type of microphones is the Shure A15RF compatible with?

The Shure A15RF is compatible with condenser microphones, as it can pass phantom power.

Where should the Shure A15RF be installed for optimal performance?

For best results, the Shure A15RF should be installed at the end of the cable closest to the microphone. However, it can also be installed at the mixer input if necessary.

Can I use more than one Shure A15RF in the same microphone line?

Yes, in cases of extreme RF interference, two or more A15RF's can be placed in series in the same microphone line, preferably with one at each end of the microphone cable.

How does the Shure A15RF improve perceived sound quality?

The Shure A15RF improves perceived sound quality by removing low-level interference components from the audio signal path, thus reducing noise and enhancing clarity.

Limited uses

Only helps with AM band RFI. Doesn’t help with modern LTG/4g and WiFi interference which is what I find most often
