Attention!
The amplifier uses a bipolar power supply.
Schematic diagram
In a typical switching circuit (TDA7294), the ULF develops 70 W of sinusoidal power at a load of 4\6\8 Ohms at supply voltages of ±27V, ±31V, ±35V, respectively. Musical power in this case is 100 watts.
To power the device, you should use a power source with a power not less than the rated power of the amplifier. Additionally, you need to install filtering power supply capacitors with a capacity of at least 4700 μF (recommended 10000 μF) in each source arm. If a switching power supply is used, it must be remembered that the peak current consumption of the amplifier can be several times higher than the average.
WARNING!
The U1 chip must be installed on a heat sink with an area of at least 600 sq.cm. using heat-conducting paste, given that its body is connected to the negative terminal of the power source.
