PROFESSIONAL POWER AMPLIFIER
Owner‘s Manual / Bedienungsanleitung 23
Specifications/Technische Daten
Amplifier at rated conditions, both channels driven, 8 Ω load, unless otherwise specified.
Depending on the ambient temperature, the unit might not operate continously at 2 Ω load in Dual Mode or 4 Ω in Bridged Mode.
In addition input power exceeds 1.1 times rated power consumption with 2 Ω load in Dual Mode or 4 Ω load in Bridged Mode
