hello!
To all the owners of Sonus 40 and 45 (and partly Sonus 60/70 and Ouverture), I ask you a small favor.
You should check a small thing.
I ask you if you can listen, from the left and right front speakers under the apron, the hiss noise (each channel, left and right, has two loudspeakers: a tweeter and a midrange, listen both).


There is no need to disassemble the speaker cloth, you just need to put your ear close to the speakers (the amplification is activated at the end of the software loading at power on).
Let me know if you notice that the left channel has an "irregular" hiss and/or that varies over time.
Obviously I am talking about very weak noises..

Thank you very very much
