Amplifier Bridging


Posted on Aug 13, 2012

The primary advantage of this method of bridging is that no additional components are needed (which means that it is cheap), and there is no signal degradation from additional opamps in the circuit path. The results are at least as good as using an external circuit, but you have to be prepared to modify your amplifier. This is not a good idea if it is under warranty! There is a negative though. Most amplifiers have a small and usually almost inaudible thump at turn-on and off, and the thump is accentuated by this technique.

Always remember that when an amplifier is operated in bridge mode, it appears to be driving 1/2 the normal load impedance, so make sure each channel of your stereo amp is capable of driving 4 Ohms if you are planning to operate into a standard 8 Ohm louds
