Product parameters:

Product Name: 2.0 Channel Qualcomm APTX Bluetooth Amplifier Board 300W+300W

Product model: ZK-3002T PRO

Adaptive power supply: Operating voltage range: DC 18-50V, no sound when the voltage is below 16V. It is recommended to use a DC power supply with a voltage of 36V-48V and a current of 10A or above. DC power supply is required, AC power is not supported!!! Reverse polarity will burn out!!! If using a DC/DC boost module, it is recommended to adjust it to 80% of the limit voltage to avoid module damage caused by overshoot or ripple overvoltage!!! )

Maximum power: left or right channel—— 300W@50V ，4Ω； 160W@50V , 8 Ω. In short, the higher the voltage, the smaller the resistance, and the greater the output power.

Compatible speaker: Supports speakers up to 3-8 ohms and 300W.

Bluetooth chip: QCC3034, transmission distance of 15 meters.

Input method: Bluetooth+AUX, Bluetooth priority. When using an audio cable for input, Bluetooth needs to be disconnected.

Number of channels: 2.0, left and right channels

Amplifier chip: TI original TPA3255

Protection mechanism: Input undervoltage, overheating, overcurrent, short circuit protection. No input anti reverse connection protection, positive and negative connections cannot be reversed!!!
