Descrizione prodotto
Characteristics
1. The potentiometer adjusts the volume with a switch for easy volume control, making it suitable for DIY speakers. If it is a metal box, you need to take out the Bluetooth antenna.
2. Copper DC connector is used to withstand high current and without heat.
3. 470uf35V solid capacitor capacitors ensure energy storage and heat dissipation, and stable power supply is a prerequisite for good sound quality.
4. Free DC head cable, compatible with the input power interface of this product, even if you do not have a DC head adapter or battery, it can be easily wired.
5. Bluetooth 5.0 version, transmission efficiency is higher, transmission distance is further.
Precautions for use: The power switch on the board is the standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug the DC plug from the machine for a long time.
Specifications
1. Material: ABS plastic
2. Bluetooth version: 5.0
3. Adaptation power supply voltage: 5-24V (9/12/15/18/24V adapter optional, high voltage high power recommended)
4. Adapter speaker: 30-200W, 4 ohm, 8 ohm
5. Number of channels: left and right stereo (stereo)
6. Bluetooth transmission distance: 15m (without occlusion)
7. Protection mechanism: Overheat protection with automatic recovery, short circuit protection with automatic recovery
8. Dimensions: 55 x 38 x 17 mm
Tip:
To have enough output power if the input is sufficient and the supply voltage/current is sufficient. The supply voltage is higher, the relative power will be higher. Speakers with different impedances will have different output power. In the case of sufficient voltage and current, the higher the ohm of the horn, the lower the relative sound power. Please pay attention!
Power supply voltage: 12V--8 ohm speaker/12W (left channel) + 12W (right channel), 4 ohm speaker/20W + 20W
15V--8 ohm/18+18W, 4 ohm/greater than 30+30W
19V--8 ohm/32 + 32W, 4 ohm/greater than 45 + 45W
24V--8 ohm/38+38W, 4 ohm/greater than 50+50W
