It connects on August MR220B mp3 input (mini jack). On the lighter. We wait for the red light flashes. We check on the transmitter reader that is well recognized (it's called pairing). And go. The range is a few meters and the sound is quite correct. Anyway enough to listen to mp3 on a micro-channel.
One slight disadvantage of August MR220B: it works on a small built-in battery. To recharge, connect the camera to a USB port. So if your microphone channel is equipped with a USB port, no problem. It still must select USB as a source for business this jack. But when used on a microphone channel is not self-powered. That said autonomy is pretty good and looking rather fast.
Alternatively, connect the USB plug of MR220B on a power adapter.
I use the MR220B on a micro channel mas it can also work well on any HIFI or on a car radio.
