Power Amplifier
Why does pro audio/dj power amplifiers have way more power for cheaper than home power amplifier?
Just looking for a basic high power amplifier for a simple 2 channel stereo system. Would rather have seperates (power and pre amp) with a lot of power than a receiver. How come pro audio looks like a much better deal?
Because most likely you also have to buy allot of stuff for it and also Comsumer amps are probably allot mo compplex. DJ amps are usually very simple (to make) where as comsumer amps also have allot of built in components to make it easier for th customer.
