Multiroom and KAR Sound: sound where you are
Built-in speakers, independent zones and one rack where all cables meet. Music plays in each room separately or across the house, and a film is watched in a cinema room with proper sound.
Status: the schemes and cabling are worked out in the project of a real site; «KAR Sound», our control layer, is in a pilot. Equipment is chosen to the client's budget and preference.
Who it is for
- Owners of villas and flats with new finishes: cables must be laid before ceilings and walls are closed.
- Clients who want a home cinema and music on the terrace and by the pool.
- Venues: cafes, bars, hotels — zones with separate volume.
01
How it works
- A star to the rackEach speaker has its own cable to the AV rack (passive 8-ohm speakers). Amplifiers can be chosen later, cables cannot.
- ZonesEach zone is a room or listening place: living room, kitchen, terrace, bedrooms, cinema. Music is independent or shared.
- SourcesStreaming services, TV, projector, players. Control from a phone, a wall panel or by voice.
- KAR SoundOur control layer on open software (Music Assistant) on a home mini-PC: one panel for sound and light. Each zone keeps playing without it, via the amplifier's own app, AirPlay or Spotify Connect.

FAQ
What if I already have Sonos?
It can be controlled from the shared panel. But local control of Sonos uses an unofficial interface, so it cannot be relied on blindly; for important functions we keep the standard app.
Is internet required?
For streaming, yes. The zones and local sources should not depend on our hub.
Can I postpone choosing equipment?
Yes. What matters now is cables and deep boxes. Amplifiers and speakers can be chosen later.
How many zones do I need?
We count places where you actually listen, not the number of rooms. We go through it together at the visit.
