Thank you for your answer it. I used +/-10V transformer with diode bridge rectifier. When i conected 6600uF caps to 0V split rail it worked however it used only about 0.6A and the sound quality wasn't that good. Now I'm considering using preamplifier but I'm afraid it will be too much for TDA7250What 'is' your power supply?
Is should be capable of providing a SPLIT RAIL output i.e. +V, ground and -V (anywhere from +/-10V to +/-45V) in the configuration you've shown. It will also have to be able to deliver up to a few AMPS current (depends on the power output you're going to expect/use).
Show a schematic.I used +/-10V transformer with diode bridge rectifier.
What is the rating of your transformer i.e. what current can it supply?it used only about 0.6A
so the problem is........?it worked
Ukážte schému.
Aký je výkon vášho transformátora, tj aký prúd môže dodať?
takze problem je...........?
In other paper it says that minimal voltage is +/- 10V. At first i thougt the low voltage but when i conected it on +/-16V there wasn't any difference.Why are you using +/-10V transformer when the circuit calls for +/-25V?
You won't get maximum output unless you use the correct power supply.
