Why loading takes place in stereo amplifier design?

analog circuit design

If loading takes place in stereo amplifier design,what must be the reason for this?in the circiut three protection circuits are present namely voltage protection,over temperature protection circuits and pin to pin short protection circuits .supply voltage is 13.2 volt. as soon as the power is on,heavy current flows.
can u tell me the reason?

Re: analog circuit design

Hi,
What you are presenting is insufficient data.

1) Is the circuit being use a standard one. If yse, check the implementation. These should be some short some where however much you dont think so. Chack the components. and sure they are operated within the specifications. Follow the data sheet. Check the Vcc ground resistance before switching ON. If it is OK then the problem is with some active devices.

2) If you have designed the circuit yourself, make sure you have followed the fundamentals. Remove the non-essential portions and check. By elimenation you may be able to find the source of your problems.
