There is a question that comes up regularly when crews see MagnetMate clips for the first time.

Sometimes it comes from the audio engineer. Sometimes it comes from the TD. Occasionally it comes from the client who has just watched the A2 attach a wireless pack to a presenter's dress using what looks like two magnets and nothing else.

The question is always some version of the same thing: do the magnets cause RF interference?

It is a fair question. Wireless audio is sensitive. Frequencies drop out. Packs detune. The last thing any crew needs is a new piece of kit introducing a variable that wasn't there before. So the concern makes sense, and it deserves a straight answer.

The short answer is no.

MagnetMate clips have been used with Shure Axient Digital, Lectrosonics, Sennheiser G4, and a range of other professional wireless systems across hundreds of shows. MCEC and ICC Sydney both run ten sets of BodyGrip as standard venue kit, used daily across multiple rooms and sessions. There have been no drop-offs, no interference, and no detuning attributed to the magnets.

Why the magnets don't cause interference

Understanding why requires a quick look at how the clips actually work.

The BodyGrip and BodyMax both work the same way. One half of the clip sits inside the clothing, against the presenter's body. The other half sits on the outside of the clothing. The two halves are held together by rare-earth neodymium magnets through the fabric. The wireless transmitter then clips onto the outer half of the mount. It is not sandwiched between the magnets, and the magnets are not in direct contact with the transmitter body or its antenna.

The magnets are separated from the transmitter electronics by the clip mechanism itself. The RF signal travels from the transmitter antenna, which sits above the mount, clear of the magnetic field.

For the FlexCapsule and LockCapsule, the magnet sits behind the lapel mic capsule only. There is no transmitter body involved. The capsule is passive and has no electronics that can be affected by magnetic interference. The N35 rare-earth magnets used in these clips are small and their magnetic field is localised.

What crews actually report

In practice, audio engineers who have used MagnetMate clips alongside professional wireless systems report no change in RF performance compared to using a standard belt clip. The packs perform the same way they always have. The mounting method changes. The signal doesn't.

This is consistent with how rare-earth magnets behave in proximity to RF systems. The magnetic field from a neodymium magnet is static. It does not pulse, oscillate, or generate radio frequency energy. RF interference comes from oscillating electromagnetic fields, not static magnetic fields. A static magnet sitting near a wireless transmitter is not generating the kind of energy that disrupts RF signals.

The one thing worth monitoring

If a transmitter has an external whip antenna and the antenna is positioned directly against the magnetic part of the mount, there is a theoretical possibility of signal degradation. Not from the magnet itself, but from the antenna being physically constrained or bent. In practice this is easy to avoid by ensuring the antenna is free of the mount and kept away from the magnets.

Standard cable management practice eliminates this as a concern entirely.

The bottom line

Rare-earth magnets do not cause RF interference with professional wireless audio systems. MagnetMate clips have been tested across a wide range of transmitter brands and models in professional live event environments, and the results are consistent. The mounting method is different. The RF performance is not.

FAQ

Do magnets affect wireless microphone signals?

Static rare-earth magnets do not generate RF energy and do not cause interference with wireless microphone transmitters. MagnetMate clips use neodymium rare-earth magnets and have been used extensively with Shure Axient Digital, Lectrosonics, Sennheiser G4, and other professional wireless systems without RF interference.

Will a magnetic mic mount cause my wireless pack to drop out?

No. MagnetMate clips have been used across hundreds of shows at venues including MCEC and ICC Sydney with no drop-outs attributed to the magnets. The transmitter clips onto the outer part of the mount and is not sandwiched between the magnets.

Can magnets detune a wireless transmitter?

No. Detuning occurs when a transmitter's oscillator is affected by external interference. Static magnetic fields from rare-earth magnets do not affect the oscillator in a wireless transmitter.

Where do the magnets sit relative to the transmitter?

One half of the BodyGrip or BodyMax sits inside the clothing. The other half sits on the outside of the clothing. The transmitter clips onto the outer half. The magnets are separated from the transmitter electronics by the clip mechanism and the clothing fabric.

What about the FlexCapsule and LockCapsule?

These clips hold a lapel mic capsule only, not a transmitter body. The magnet sits behind the capsule. The capsule is passive and has no electronics that can be affected by magnetic interference.

What type of magnets does MagnetMate use?

MagnetMate BodyGrip and BodyMax use rare-earth neodymium magnets. The FlexCapsule and LockCapsule use N35 rare-earth magnets.

Has MagnetMate been tested with Shure Axient Digital?

Yes. MagnetMate clips have been used with Shure Axient Digital and other professional wireless systems without interference.

What about antenna placement?

The transmitter antenna should be kept free of the mount and away from the magnets. Standard cable management practice covers this.
