Atoll Electronique SDA300 Signature

De SDA300 Signature is ontworpen om de integriteit en complexiteit van muziekstructuren vloeiend te reproduceren. Hij biedt gratis toegang tot internetradio’s en stelt je in staat om live en in hoge kwaliteit af te spelen vanaf de belangrijkste streaming sites. Het staat open voor je hele netwerk en heeft een zeer complete connectiviteit. Het zet binaire code om in een analoog signaal met opvallend realisme. Als alles-in-één concept gaat hij nog verder door te functioneren als een complete muziekspeler en geïntegreerde versterker met behulp van het versterkergedeelte van de IN300.
