In the quest of helping out a friend and to check ones capabilities as an engineer we built a 4 channel amp right from the ground up , its to be used in a bi- amp setup with active crossovers. Without further delay here are the specs.
CH1 - 110W@8E , 170W @ 4E
CH2 - 30W@6E , 45W@4E
CH3 - 110W@8E , 170W @ 4E
CH4 - 30W@6E , 45W@4E
SNR > -95DB
THD <= 0.1%
DAMPING FACTOR FOR CH1 & CH3 >= 800
DAMPING FACTOR FOR CH2 & CH4 >= 400
THERMAL , OVERLOAD, SHORT-CIRCUIT, DC DETECT , DELAYED TURN-ON PROTECTIONS, SOFT START
****(We have grossly under rated the amp output power , it put out significantly more power thanks to 750VA transformer)
These are some of the features of this humble amp , it also has signal detect led on front panel along with protection indicator.
its a fun journey doing every thing from the ground up , hope u guys like it too.


Regards
ONB

HI .. I am no techie on this.. but could you explain what the power ratings mean.. why do the channels have different ratings? and what is that 8E, 6E ...4E.. sorry if these are noob Qs !
 
Great project! thank you for sharing. A full log of the build, complete schematic, as well as components detail and explanations of the individual aspects of the circuit if possible will be much appreciated.

Hi, the different channels have different power rating because it's to be used for bi - amp , 30W for the tweeter and 110W for the woofers , 6E , 4E is the impedance of the speakers...
