Axiom Home Page Forums General Discussion Technical Questions Denon with external amp

Even if a receiver leaves both its internal amps and pre-outs active at the same time, bi-amping is going to be a problem. Adjusting the channel trims will cut both the internal amp, and the signal going to the external. Unless the external has exactly the same gain as the built-in, you're going to end up with half the speaker at a different level. You'd have to use an external amp with it's own trim setting.
