Hi to all , I'm new here and i don't know very well english.
Ok now i'll tell you my problem about the costruction of a dolby sorround 8.1.I want create it whit a mpc509 (analogic multiplexer) for channel choosing, a tda3810 (this chip create spatial stereo) for the rear channel , and lateral channel , a lm324( low power op-amp) for preamplifing all but before of the pre amplifier i want put some cross over that for the high cut (300hz to 20khz) and low cut (20hz to 300hz), 8 high cut for all the channel and one low cut for the sub channel. I want to use four LM4780 for the eight channel but i don't know what use for the sub. Second you a bridged lm4780 can be good ? How can be the dissipation of all this component second you ?
Excuse me if I've wrong , but i didn't know where wirite this thing
