This is my DIY try make a 5.1 home theatre processor that can split stereo signal into 5.1 and can be amplified by my previous 5.1 power amplifier LM1875 & TDA7294.
I design this 5.1 Processor with op-amp system, it's so simple and small because it use smd components.
This 5.1 Home Theatre processor have some output :
Front left and right output with wide stereo,
Center channel out from L+R and have a bandpass filter to make good dialogue on movie,
Surround/rear output, the signal substracted L-R and R-L and it still in a stereo so that can produce correct position of sound , and it filtered by 7KHz lowpass filter to make good sound signal.
The last is subwoofer out with subwoofer freq adjustment so you can easily match your speaker.
This 5.1 processor need symmetrical supply 12V-0-12V from transformer, at least about 1Ampere. So, what does it sounds like? please check the video.
