Hi VM,
Nice to hear that you have gooed experiences with the MTP40.
My company has bought 15 transmitters MTP42 en 15 MCR42 set's of Wisycom.
The biggest reason for buying these transmitters is the bandwith. Here in The Netherlands it is a problem to find a good useable frequency. Tha's the reason why a lot of companies bought the Wisycom transmitters.
But last week i've worked with 4 MTP40 transmitter. I was working in a studio were it was very quiet. In that situation i've noticed that all of my four transmitters produces a lot of audionoise! A noise you can compare with the noise of a airco unit. But i didn't worked in a room with that noise! During shooting i have to switch recording from using the Wisycom transmitters in using the audioboom. The "airco-noise" produced by the Wisycoms was at that high it was a really problem for the recording.
Later on i've tested the transmitters in a absolute quiet room. All four transmitters produced the "airco-noise" at the same level. Even when i didn't connect the microphone to the transmitter there was the noise. The most rare experience was that the level of the noise produced by the Wisycom varied by the chancing of the audiolevel input. So it wasn't possible to get a better audio-noise level.
A day after i've tested the Wisycom MPT30 with the Wisycom receiver MCR42. Everthing was good. No rare "airco-noise" level produced by the transmitter. Even a test with a Sennheiser SK50 transmitter in combination with MCR42 was a good result.
Very strange. But for me is this situation is unuseble. So i will work with Sennheiser or Micron transmitters. I hope this problem wil solve by Wisycom.
Do you have the same experiences??
The "airco-noise" is irritating in very quiet situations.
We are using Tram microphones for all of our transmitters.
I realise that Wisycom has solld a lot of these units and on the internet i can't find anyone who has the same problems as described.
So i hope it will be problem that's easy to correct. So i like to hear if anyone else has the same problems.
