TDA7492P digital power amplifier chip, design optimization, circuit design, sound quality is very good, big power.
DIP switching amplifiers can be adjusted directly after gain more respect and promote greater damping cushion.
Power supply: 2.1 interface, 8 ~ 25V DC power supply
Audio input: stereo input and various versions of the Bluetooth connection, using Bluetooth chip CSR8635, Bluetooth V4.0, software compatibility high
Output impedance: 8 ohms (best 4,6,8,16 ohm impedance can drive the speaker)
Output power: join of 5532, output power of foot (25V supply, 6 ohm output impedance of 2 * 50W, 8 ohm output impedance 2X40W dual channel), dial switch can be directly adjusted power amplifier gain more convenient, better promote greater horn of damping
Method of use: connect the power and wait 3 seconds, until the LED blue light and red light flashing alternately, then you can use your device to find my Bluetooth module, you will find SANWU audio “, and then connect it, then you can use memory to automatically connect directly.
Size: 183mm X 50mm X 23mm
