NJW1186 Surround Sound System

A very simple 5.1 surround audio system can be constructed using NJW1186 is a surround processor for 5.1 channel speaker system regenerates center, surround and subwoofer channel signal from normal stereo signal input. NJW1186 contains the passive matrix circuit, BPF with the center channel, LPF for the subwoofer, simulated stereo for the surround channels and size for each channel.

All internal status and variables are controlled by I2C bus.

As you can see from the diagram, this 5.1-channel surround sound system is very simple to design and require few external electronic components.

NJW1186 surround processor is manufactured by New Japan Radio Co. Ltd.

This draft of the electronic audio 5.1 surround sound processor can be powered from a wide range of input voltages from 7.5 volts to 13 volts.

Outputs of a surround system: subwoofer channel SWOUT, RSout-right surround channels, the left-channel output LSout surround channel field-Center.
