Just finished the kDCX project. Tested and sound great.
Only issued is the input C , I connected the mic and run the set up for room correction and time delay, but not have any signal from mic.
Thanks ! for great project Ti.

Check the circuit section pertaining to input C to see if you spot any errors, perhaps reflow the solder joints on the opamps.

Thanks ! Anand :) I like this name.

As today I'm working on input C and found R52 (10 ohm ) that supply 5 VDC to the relay section is burn out. Replaced R52 and make the measurement voltage at R52 I got 5 VDC on one side and other side I got only 0.25 VDC and resistor is very hot. At this point I just did connected R52 for now and will work on later. Is possible may be one of the Q50,Q51 or Q52 IS BAD ?

Regards,
Iggy

Check the orientation of D50, D51 and D52. Also do a BJT sanity check on Q50, Q51 and Q52.
