I have all yamaha silent brass with ST9 sourdinne trobone for PM5.
PM5 is mute for trombone and bass tnor. Having a low tnor and I test on two planks and no problem. It fulfills its rle, we close the door and the neighbors hear anything.
For what is the sound, I find it too mtallique this bunch much of the grain of the instrument, but means much the accuracy of the instrument. This unit is supplied with headphones, plutt correct.
It's been six months and I have no particular worries. My neighbors are rather SATIF not to hear me. This requires a little practice because it is true that the sound with headphones is a bit spcial but if done quickly.
I find it much better than just sourdinne dumb because you can get along and even play with (there is a function reverb on the case). In terms of using it as pure micro to the scne or registration by the cons must be avoided is not for ca. It changes the sound too.
The price is lgrement lev (Envrionment 200). Anyway I would do the same choice.
I was looking for a system that's to make changes in real time, well I think I found!
Mute PM5 has a particularity: it cut all the acoustic sound!
Although the sound is not at the appointment (at the same time it is not frowned upon or is placed the microphone could be expected worse!), To make changes in the type distortion, Octavia, flange, harmonizer and so on! trs's enough good!
the only BMOL may be that the micro ncessite power, then we can not do without the box ...
I'm using at the moment an old version, ST7, which blows a lot. The ST9 replace it seems to me, with the ST5, but I do not know what is the signal to noise ratio.
has recommended to acousmatic music!
Note: The PM5 is a kind of UFO in his field, he does not seem to have no other work Systm mute amplifier ...
