preamplifiers?....info please...?
I have a Marantz integrated amplifier,120 watts per channel...Cerwin Vega 500 watt speakers...will a preamp help add power to drive my speakers?...I`ve looked at Carver preamps but they do not list watts and they have a volume control...how do preamps work???
The output from a microphone is very weak. It's too weak to be amplified by a power amp. A preamplifier boosts the mic signal so an amplifier can deal with it. But the output of a preamp is still small, too small to be rated in watts. It won't make the amp output any louder than it's rated output.
