Reports[edit]
- From original brochure: selected close tolerance components, direct signal routing, high power toroidal transformer. Even low impedance loads cannot impress the RB870BX due to its high reserves, which is why it can drive difficult speakers without any problems. In mono bridge connection the RB870BX delivers a channel power of 300 W.
