High quality.
Features:
Model: TDA7293 / TDA7294
Power supply: double AC 15V to 36V (AC must be balanced and filtered) or DC positive and negative 18V to 50V. Recommended double 35V (Note that this is not a double 35V transformer, but a positive and a negative 35V DC transformer. It is recommended to double the ring core transformer with 26V/200W after the rectifier voltage is about twice the 35V.)
Reminder: the battery can be used. (Must be a battery in series).
Transformer Power: The power of the power supply transformer should not be less than 200W when using the two channels. The power supply transformer should not be less than 100 W in mono. The power supply rectifier filter: the total of the two channels should not be less than 40,000 uF, the rectifier bridge is preferably 25A or more.
Output power: maximum output power 85 W.
Midpoint voltage: less than 1mV
Load: Large-format floorstanding speakers can be advertised for home use.
Cooler: According to the supply voltage, the power supply has a high thermal output and a large output power.
