5.1 processor for home theatre
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 on Barlex Respectaizer youtube channel
