Features
1.Adopt high power digital amplifier special inductor, high current, low magnetic loss, small heat, use oxygen-free copper wire to improve the sound quality; magnetic shielding mechanism anti-electromagnetic interference.
2.QCC3034 high-pass module, support the transmission code SBC, AAC, APTX, APTX-LL, APTX-HD.
3.QCC3034+PCM5102A, lossless transmission, lossless decoding, no loss, perfect display of the sound of all dynamics and details, high-frequency burr-free, rounded midrange, low-frequency powerful, elastic.
4. Extremely high parameter performance: dynamic 112dB, signal-to-noise ratio 112dB, distortion -93dB.
5. With protection mechanism, with input undervoltage, input anti-reverse connection, overheating, overcurrent, short circuit protection.
Specification
Product Name: 2.1 channel high pass Bluetooth amplifier board 100W+100W+200W
Product Model: ZK-APTX1
Adaptable power supply: operating voltage range 12-30VDC, recommended voltage 24V-28V, current 10A or 10A or more DC power supply.
Maximum power: left or right channel - 105W@30V, 4Ω; 55W@30V, 8Ω. subwoofer - 208W@30V, 2Ω; 105W@30V, 4 Ω. In short, the higher the voltage, the lower the resistance, the higher the output power. The higher the voltage, the lower the resistance, the higher the output power.
Adaptable speakers: Left and right channel, support 3-8 ohm, within 100W; subwoofer support 2-8 ohm, within 200W.
Bluetooth chip: QCC3034, transmission distance 15 meters.
Input mode: Bluetooth+AUX ,Bluetooth priority, Bluetooth needs to be disconnected when using audio cable input.
Number of channels: 2.1, left and right channels + subwoofer
Amplifier chip: two TI original TPA3221
Protection mechanism: input undervoltage, input anti-reverse connection, overheating, overcurrent, short circuit protection.
Product size: 118x100x25mm
Add external antenna (special scene):
1.The boards come with on-board antennas, normal distance 10-15 meters, if it is mounted into a metal case (will shield the signal) or increase the Bluetooth distance (20-30 meters) only use the external antenna.
2.Need customers to buy their own 2.4G antenna (antenna extension cable, antenna bar), this product does not include external antenna.
