Store music on anSD card so your playlists are always available, with no need to rely on external devices. Flipping between sources is smooth, whether via the panel or included remote.

25W x 2 Class D Amplification

Balanced stereo output powers two passive speakers as standard (4 can be used if needed), filling living rooms, bedrooms, kitchens, or offices with clean, detailed sound. It suits both 4 Ohm and 8 Ohm setups for versatile installation.

Safe In-Wall Installation

All wiring routes inside the wall, getting rid of loose cables and reducing hazards. The supplied back box cuts installation time and removes compatibility guesswork. The unit is mains powered directly so there are no bulky power supplies to accommodate.

Line Output for Expansion

The dedicated line level out lets you add active subwoofers or extend the system across rooms, ideal for bigger spaces or multi-zone audio solutions.

Handy Doorbell Trigger

Amplify your wired doorbell through your audio system, making sure you’ll hear guests even when music is on.
