Atoll SDA300 Signature Silver

The SDA300 Signature is designed to reproduce the integrity and complexity of musical textures with great fluidity. It offers free access to online radio stations and lets you play live, in high definition, on the main streaming platforms. It is open to your entire network and has very complete connectivity.
