Proper hook up for mono mode .. most power amps.
We get a lot of power amps in for repair because they have been switched into mono (bridged) mode and were not properly hooked up to run in this mode.
Mono mode in most power amps configures the amp so that 1/2 of the wave form is amplified by each side of the power amp. As a general rule once the unit is switched into mono mode you must use the two red binding post only to hook up your speakers some amplifiers will have a dedicated output for mono mode and this output will be marked as such. Also as a general rule a power amp ran in mono mode does not want to see a total load below 8 ohms. Unless the amp is marked other wise running a speaker load below 8 ohms will either drastically shorten the life of the amp or outright fry it.
