Product Name: 2.1 channel Bluetooth amplifier board 100W+100W+200W
Product Model: ZK-ST21
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 channels, support 3-8Ω, up to 100W speakers; subwoofer support 2-8Ω, up to 200W speakers.
Bluetooth chip: Jelly 5.1, transmission distance 15 meters
Input mode: Bluetooth + AUX + U disk + sound card
Number of channels: 2.1, left channel + right channel + subwoofer
Amplifier chip: two TI original TPA3221
Protection mechanism: input undervoltage, input anti-reverse connection, overheating, overcurrent, short circuit protection.
Product size: 121x100x25mm
1 x ST21 amplifier board
1 x Enclosure kit (optional)
5 x Cable (optional)
1. Shipment does not include power supply, audio cable.
2. Add external antenna (special scene):
2-1. board are with on-board antenna, the normal distance of 10-15 meters, if it is loaded into a metal shell (will shield the signal) or increase the Bluetooth distance (20-30 meters) will only use the external antenna.
2-2. Customers need to buy their own 2.4G antenna (antenna extension cable, antenna bar), this product does not include external antenna.
