Good morning

I'm David B. and I recently finished composing the music, movies and games room in which I use Sonos components with full satisfaction, namely: an Arc, a Sub 3 gen and two was 300.

The question I ask you is the following:

How do I connect my Yamaha psr sx 600 music keyboard to the Sonos system?

I already bugged the Line in adapter for Sonos era 300 and I connected a jek cable 2 in one (2 6.3 mm cables connected to the aux output of the keyboard that end up in a 3 mm jek) connected to the Sonos adapter that I connected to an era 300.

But you can't hear anything.

Can you help me solve the problem?

Thank you and I wish you a wonderful day

David

Easier to understand now that I have posted the translation.

If, as I suspect, you have set up the Era 300s as surround speakers for the Arc, that automatically turns off any line in functionality. You would need to add another Sonos device with a line in to add to your existing system to get the data from your keyboard in to the Sonos system…but you won’t like it. All Sonos line ins are subject to at least a 75ms delay, which would impact your ability to ‘hear’ the keyboard while you’re playing it. 

Sorry. The Sonos system just isn’t designed to be used as a “public address’ type of system, which means microphones, keyboards, karaoke machines are just not a good idea. 
 

Spanish:

Es más fácil de entender ahora que he publicado la traducción.

Si, como sospecho, has configurado los Era 300 como altavoces envolventes para el Arc, eso apaga automáticamente cualquier línea en la funcionalidad. Tendrías que añadir otro dispositivo Sonos con una línea para añadir a tu sistema existente para obtener los datos de tu teclado al sistema Sonos... pero no te gustará. Todas las ins de línea de Sonos están sujetas a un retraso de al menos 75 ms, lo que afectaría su capacidad para "escuchar" el teclado mientras lo está reproduciendo.

Lo siento. El sistema Sonos simplemente no está diseñado para ser utilizado como un tipo de sistema de "dirección pública", lo que significa que los micrófonos, teclados y máquinas de karaoke no son una buena idea.

Grazie mille per le spiegazioni

mi godo Sonos per quello che è progettato, vorrà dire che prima incido la musica, poi l’ascolto

Felice giornata

David
