Is the receiver output mic level or line level?
Asked by: Anonymous
i am not an audio guru. can only tell you what works for comes with a short resistive cable that brings the signal down to mic in level on my zoom 4. maybe without the cable it is line in? going straight from reciever to mic in on zoom recorder results in distorted audio. using supplied resistive cable between reciever and zoom results in great audio.hope this helps.

How many devices will this connect to? I need a microphone to connect to up to 50 devices.
Asked by: Anonymous
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.

Does it work with Canon XA30? Why no sound recorded when plug to Mic, Input 1 or Input 2 ? Please help.
Asked by: HONG L.
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.

Hi, I would like to use such Bluetooth Wireless Microphone System for my Samsung Note 4 phone. Is it compatible?
Asked by: Anonymous
i have not been able to make the mike work with a phone or computer. this is a sony bluetooth product and it can carry a signal a couple hundred feet. i don't think it is you standard bluetooth frequency and sony makes no claims that it would work this way. i think it is proprietary system.
