CA-7297 Audio Amplifier Board Module Dual-Channel Parts For DIY Kit Dual-Channel 15W+15W Digital Amplifier
Voltage: DC 12-24V, Recommended DC voltage 12V, current above 2A
Power: 15W + 15W
Output Impedance: 4-8 Europe
The board Advantages: boot no current impact sound, hi no static noise! Sound quality is super good - treble delicate, soft, transparent, no harsh; bass strong, full, strong, and acting freely. Recently, some customers have reported that this small plate a little noise, mostly because of the power problem is not solved. After testing, the battery or power supply using 12V2A 12V30W more than a little noise transformers are not, if the switching power supply or other variable power supply, due to the poor may produce linear low-noise
The core of the amplifier board TDA7297 imported two-channel amplifier chip, the famous European SGS-THOMSON STMicroelectronics produced. DC power supply is designed to supply power directly available 12V battery voltage range: 9-15V, recommended voltage 12V, output power up to 15W + 15W, the peak power of 30W + 30W, the sound volume is small but super shock for any occasion.
