The Sonos ZonePlayer ZP80 is designed to be used with an external amplifier. It contains both analog and digital outputs so you can easily connect it to your existing audio equipment.  Perfect for adding streaming of music services to your existing hifi system.  Can be used as part of Sonos multiroom system.  

Controlled by S1 App (not compatible with S2) or with Sonos Controller.  In good condition.  Was working perfectly 2 years ago when I still had S1 system, but now not able to check (hence price).  However, switches on and searches for system, but I cannot guarantee this is 100% working.  Comes with power cable.  

Please note that although item powers up, I have not been able to test it fully, so cannot guarantee it is fully functioning.
