Is the microphone in this setup a lavaliere?
Is the microphone in this setup a lavaliere?
No, the Sony ECM-AW4 Bluetooth Wireless Microphone System does not include a lavalier microphone. The transmitter features a built-in microphone, so it can be used as a clip-on mic by itself or a lavalier microphone can be purchased separately to connect to the transmitter's 3.5mm mic input.

question
Is the receiver output mic level or line level?
The receiver is supposed to be connected to the camera at the mic input. Surely its output level is for mic.

question
How many devices will this connect to? I need a microphone to connect to up to 50 devices.
They will only connect to each other. The instruction manual for the Sony ECM-AW4 Bluetooth Wireless Microphone System states that the receiver and the microphone are factory-set to communicate with each other. Communication is not possible with a receiver and microphone not sold as a pair, multiple microphones, or any other Bluetooth device such as a smartphone, computer, etc. As the units only work in pairs, you may not use them simultaneously for usage on multiple units.

question
Does it work with Canon XA30? Why no sound recorded when plug to Mic, Input 1 or Input 2 ? Please help.
Make sure you are plugging in the receiver (not the transmitter) into your audio in jack. It should work. Try all inputs until you get it to work. If it does not, try a different microphone to make sure your camera is working correctly and check its setting to accept a mic in. Use a headphone on the receiver; are you getting sound? If not, you have a defective product.
