TDA7293 2.1 Channel Subwoofer Amp Amplifier Board Finished Board ( Upgraded Version with Protection Circuit )

TDA7293 2.1 Channel Subwoofer Amp Amplifier Board Finished Board ( Upgraded Version with Protection Circuit )

Description
- Input voltage : AC24V-0-AC24V ( range voltage applied at 22-26V) transformers require more than 300W at full power , be careful not to use what virtual target transformer
- Output power : Subwoofer 160W + Left 80W + 80W left
- Board Size : 236 X 98 X 50MM length X width X height (without potentiometer )
- Function : This amplifier board can output all the way to the subwoofer , all the way to the left and right audio channels for each output , consisting of 2.1-channel , can replace a variety of class 2.1 amplifier system upgrade

The amplifier board features: All components are careful selection
- 25A rectifier bridge with 10000UF X 6NOVER pitched AUDIO grade fever tonic capacitor , sufficient to meet a variety of large dynamic output
- with output protection circuits , delay protection , the midpoint voltage protection , switch machine yuan impact , perfect speaker system protection , protection from imported Omron relay silver contacts , durable , top quality
- Selection of Original Dark word TDA7293 IC quality assured
- Original 5532 op amp with Texas , although the op amp has long history , but it is undeniable that sounds good , was once king of the op amp , op amp with a gilded seat , you can also replace its own variety of more a high level of operational amplifier without welding
- Coupling capacitance , the choice of the Italian AV audio coupling , the coupling levels are low loss fever , this board is so special is that each channel coupling two parallel, one for 1UF one is 3UF, benefits of doing so is to make alt brighter, fuller low frequencies , but increases the cost
