Audison Voice AV 5.1k

Audison Voce AV 5.1k - 5-Channel Amplifier with 1650 W for Front, Rear and Sub

The Audison Voce AV 5.1k is a 5-channel amplifier that operates with a hybrid design of Class A, AB and D. This allows you to power front, rear and subwoofer from one amplifier – or drive an active front plus a powerful sub. The integrated mono section delivers up to 1000 W, while two Class A channels provide high-resolution front signals and two AB channels ensure dynamic drive. The analog input stage can be converted using an optional digital input card.
