Built in boost module, single power supply can be converted into dual power supply, with a large dynamic range. <br/>5. Dual impedance output interface design, high impedance and low impedance meet the connection requirements of different power amplifier devices.</p><p>Product Introduction: <br/>This circuit uses TINE5532 three chips, with one level gain, one level buffer, and one level tone processing; Equipped with a power on/off silent circuit, there is basically no impact sound when turning on/off; Reverse polarity protection for power supply; Wide voltage regulation, suitable for DC 9-29V range; Equipped with a built-in boost module, it can convert a single power supply into a+14.5V dual power supply to power the circuit, with a large dynamic range of sound and strong thrust, which can drive high-power rear stages. There are two impedance interfaces designed for the output, which facilitate the connection of different power amplifiers. The low impedance interface can be connected to a pure rear stage power amplifier, while the high impedance interface can be directly connected in parallel to the input end of a combined power amplifier or other audio equipment circuit with a front stage.</p><p>Parameter: <br/>Supply voltage: DC9-29V <br/>Static power consumption: about 1W <br/>Frequency response: 20HZ-20KHZ <br/>Amplification gain: 14db <br/>Tone adjustment range: ± 15db <br/>Input impedance: 50K <br/>High impedance output impedance: 10K, output amplitude: 0.7Vrms <br/>Low impedance output impedance: 600 Ω, output amplitude: 3.5Vrms <br/>Size: 50mm * 80mm</p><p>Package Include: <br/>Front board X1 <br/>3P terminal wire X2 <br/>2P terminal wire X1<br/><br/></p></div></div><br/>
