ZK-AS21P Hi-Fi 2.1 Channel Bluetooth Amplifier Board 300W+300W+600W TPA3255*2

Popular

Product Introduction

Features:
1.High current, low magnetic loss, small parasitic capacitance, low heat generation, use oxygen-free copper wire to improve sound quality; magnetic shielding mechanism anti-electromagnetic interference EMI performance.
2. Thickened heatsink, silent long life fan; solve the heat dissipation problem, better able to play the advantages of high-power
3. Transparent sound, fast low-frequency response, mid-frequency texture, high-frequency smooth, tangent loss is very small
4. Extremely low noise, pure sound quality, very low distortion, guarding your experience of the original sound
5. High-density winding shielded wire + high-quality connectors; outside the winding shielding using high-density environmentally friendly tinned copper wire stranded production from high density, high density, for connecting the signal to play a good shielding effect.
 
Product parameters:
Operating voltage range: 18-50VDC, limit 53V. recommended voltage 36-48v, current 12A or 12A or more DC power supply.
Maximum power: left or right channel---300W@50V, 4Ω; 160W@50V, 8Ω subwoofer---600W@50V 2Ω; 300W@50V,4Ω; 160W@ 50V, 8Ω; in short, the higher the voltage, the smaller the resistance, the greater the output power
Bluetooth chip: Jelly 5.1, transmission distance 15 meters
Input mode: Bluetooth + AUX + U disk / sound card
Number of channels: 2.1, left and right channel + subwoofer
Amplifier chip: two original TPA3255
Protection mechanism: input undervoltage, overheating, overcurrent, short circuit protection. No input anti-reverse protection, positive and negative poles can not be reversed!
