Audio Control 

Theres nothing like sitting at home playing music when and where ever you want, indoors, on the terrace or just chilling out in the bedroom, or showing off you're sounds in party mode,

​

This is possible with an audio control system, (audio Matrix) for example,  via an app smart phone, touchscreen or keypad with either fro example Crestron or Control4 

DHS have many options for this from one room solutions to every space with audio, you choose.
