Product Specifications:
Product Name: 2.0-Channel Qualcomm APTX Bluetooth Amplifier Board 300W+300W
Model Number: ZK-3002T PRO
Power Supply Compatibility: Operating voltage range: DC 18-50V. No sound output below 16V. (Recommended voltage: 36V-48V, current: 10A or higher DC power supply. Must use DC power only—AC power is NOT supported!!! Reverse polarity will cause burnout!!! If using a DC/DC boost module, adjust to 80% of the rated voltage to prevent damage from overshoot or ripple overvoltage!!!)
Maximum Power: Left or Right Channel—300W@50V, 4Ω; 160W@50V, 8Ω. Higher voltage and lower resistance yield greater output power.
Compatible Speakers: Supports 3-8Ω speakers rated up to 300W.
Bluetooth Chip: QCC3034, transmission range 15 meters.
Input Methods: Bluetooth + AUX (Bluetooth priority). Disconnect Bluetooth when using audio cable input.
Number of Channels: 2.0 (Left/Right)
Amplifier Chip: Genuine TI TPA3255
Protection Mechanisms: Input undervoltage, overheating, overcurrent, short-circuit protection. No reverse polarity protection when no input is connected. DO NOT reverse positive/negative terminals!!!
