Do I still need a clap if I use a wireless system?

Not for the wireless audio itself, since it is recorded into the camera file. Clap anyway if you are also recording a backup on the transmitter or a second device, because that gives you a visual reference to align the backup if you ever need it. It costs a second per take.

Is 32-bit float recording actually useful?

Yes, for one specific problem. It captures a range wide enough that a level set too low or too high can be recovered in software without the distortion you would get from a clipped 24-bit file. It does not fix a bad microphone position, wind noise or a room with hard walls, which are the problems that actually ruin most interviews.

How many wireless channels can I run at once?

It depends on the system and the band it uses, and the honest answer is fewer than the maximum in a crowded room. Two transmitters to one receiver is common and reliable. Beyond that, check whether the system supports it, and expect range to fall as the number of active links and nearby transmitters rises.

Where should a lav be placed?

About a hand width below the chin, centred, on the outside of clothing where possible and clipped so nothing rubs it. Move it off-centre if the subject will turn their head one way, and never let a collar, scarf or lanyard touch the capsule. Placement matters more to the result than the price of the microphone.

Wireless Mic System vs Recorder and Lav (2026)

Short answer

A wireless system gives you audio in camera, monitored live, with nothing to sync. A recorder and wired lav gives you a cable that cannot drop out and a file that cannot be ruined by interference, at the cost of syncing every clip in post. For interviews with one or two people and a laptop workflow, either works. For run and gun where you cannot reshoot, the wireless system wins because you can hear a problem while it is happening.

Choose the DJI Mic Mini 2 TX and 1 RX if…

You shoot alone, you move, or you cannot go back and reshoot. Hearing the subject in your headphones at the camera is the difference between catching a rustling shirt in the first minute and discovering it in the edit. A system with internal recording on the transmitter also gives you a clean backup file if the radio link stumbles.

Radio is a shared resource and it is not guaranteed. Crowded venues, other production teams and dense concrete all cost you range. Keep line of sight where you can, do a walk test at the actual location before rolling, and use the transmitter internal recording as insurance rather than as an afterthought.

Choose the Zoom H1 Essential Recorder if…

You shoot seated interviews, you have a laptop and a few minutes per clip, and you want audio that physically cannot drop out. A wired lav into a pocket recorder is the cheapest reliable audio in this whole category, and 32-bit float models remove the risk of clipping a level you set wrong.

Plan the sync before you shoot, not after. A clap at the top of each take, or matching timecode, turns syncing into a batch operation instead of a chore. Also plan the cable route, because a lav cable that runs outside clothing is visible and a cable that rubs a jacket makes noise on every move.
