<b>About us:</b><br> This is an audio power amplifier board that enhances low-power, inaudible electronic audio signals, such as those from<br>radio receivers or electric guitar pickups, enough to drive speakers or headphones. The power amplifier allows the listener to hear the signal. <br> It contains a TDA7297 power amplifier chip, the design optimizes the circuit layout, the sound quality is very good, and the power is large.<br><br>With this module, the sound quality is very good.<br><br> Mono digital audio power amplifier chip.<br><br> High output and low power consumption.<br><br> Applicable speaker impedance: 4-8 ohms (8 ohms is the best).<br><br> <b>Package including: </b><br> 2pcs x Power amplifier board module <br><br> <b>Module performance and features:</b><br> -Onboard TDA7297 audio power amplifier chip, dual channel 15W+15W, suitable for 4-8 Ohms, 10-50W speakers<br> <br>-The main pin of the chip has been led out, convenient for external device control, onboard 2 channel 5.08 (mm) pitch 2P binding posts, <br>respectively for left and right channel wiring output<br><br> -The onboard dial potentiometer can adjust the volume output size;<br><br>-The power input mode is DC5.5*2.5<br><br>-Supports DC power supply, terminal block, and pin 3 power input mode.<br><br>-Onboard 10K adjustable resistance, you can adjust the volume amplified Onboard power indicator<br><br>-Major pin of the chip has led, can be directly input audio signal<br><br>-Operating voltage: 6 ~ 18V<br><br>-Board size: 45 (mm) x 33 (mm) x 25 (mm) L x W x H<br><br>-Overall over temperature protection<br><br>-Weight: 17g<br>

• Super material: It is made of electronic accessories, nickel plating on surface(anti-oxidatioan), inner conductor: pure copper. It is long lasting and durable for you to use.
• Package including: 2 pack of power amplifier board. A large area of copper and dense vias hole enhance heat dissipation. it has current limiting, short circuit and over temperature protection. Even if the output is short circuit, it will not burn out the module and it is safer
• Input power: Input power is about 4-8 Ohms, 5-15W. Working Voltage is about DC 6 ~ 18V .
• High Power High Efficiency: High reliability, strong vibration resistance, good electromechanical performance. Sound quality is very good by using this module. Mono digital audio power amplifier chip.High output and low power consumption.
• A wide range of applications: Applicable speaker impedance is 4-8 ohms (8 ohms is the best. This module can be applied to audio system, household power system, DIY speaker etc.
