Hi All,
I have the attached Class D Amp that has no Data on it as to its Origins.
1)
Front end is an ADAU1701 Dsp board with input and controls.
2)
The ADAU1701 has two outputs one for HF and one for LF
3) The attached photo has the ADAU1701 and the LF section.
4) The LF section is a Class D/SMPS Combi. and is housed in a 1200Watt Sub cabinet.
5) The HF unit is satelite.
The sub is used in a church environment and subsequently blew up the mains fuse and fried the LF speaker.
I need a schematic or help to identify this unit so that I can workout how to rectify, the fault.
Replacing the fuse and connecting through a bulb indicates all is well but there is a sort of "Phatting" sound out of the LF speaker with no input.
Thanx in advance for the help
Ike
