Hello for everyone,
I have recently developed this 4 channel module based on LM4766, in order to use for my self and to other diy people.
On this module, it's outputs are configurable as 4x50; 2x100; or 2x50 more 1x100 Watt making it suitable for Hifi stereo,
bi-amplified speaker system or multi-channel.All channel are free of noise "no hiss" very clear sound.
On the example pictures shows that with the optional trimmers which were applied on channel 3,4 the output offset
voltages can be adjusted near to zero, without trimmers on channel 1,2 the output offset voltage was around -4mV.
For more info you can also check this module on chip amp forum.
I have listed this module with both isolated and non isolated IC's at my page if you have interest you can check here:
