#HIFI #5.0 #Bluetooth #Amplifier #Board #Wireless #Audio #Digital #Power #TPA3116D2 #50W #x #2 #Dual #Channel 100% brand new and high quality Features: Made of high quality materials, high performance, high price, high quality power amplifier for HIFI music. 5.0 Bluetooth version has high fidelity and two-channel stereo sound quality, with higher efficiency and farther transmission distance. As a Class D amplifier IC from TI that has very high index parameters. The modulation frequency can be up to 1.2MHZ, and the high power output distortion is less than 0.1%. With AUX and Bluetooth two audio input methods, 2 in 1. It adopts copper DC connector and fence type terminal. It can withstand large current, no heat, no damage to the wire, good wiring and short circuit. With a filter inductor, the sound is round and clear. Free DC head lead, compatible with the input power interface of this product, even if you don't have a DC head adapter or battery, it can be easily wired. It also comes with a volume adjustment function, which rotates the chirp potentiometer clockwise to zoom in and counterclockwise to decrease. 2 optional types can be selected, great for DIY speakers. Specification: Model: ZK-502C Bluetooth version: 5.0 Material: Fiber glass board and electronic component Size: app.82 x 50 x 18mm/3.23x 1.97 x 0.71in Optional types: A(With shell); B(Without shell) Clip solution; TPA3116D2(with AM interference supperssion) With or without filter: Yes(filtered sound is more round and clear) Supply voltage: 5-27V Speaker resistance: 4-16Ω Speaker power: 30-200W Adaptation supply voltage: 5-27V(optional 9/12/15/18/24V adapter, high power recommended high voltage) Adapter speaker: 30-200W, 4Ω，8Ω Number of channels: Left and right stereo(stereo) Bluetooth transmission distance: 15m(without occlusion) Protection mechanism: Overvoltage, undervoltage, overheating, DC detection, short circuit protection Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller 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 30W 15V--8 ohms/18 + 18W, 4 ohms/greater than 30+ 45W 19V--8 ohms/32 + 32W, 4 ohms/greater than 45+ 50W 24V--8 ohms/38 + 38W, 4 ohms/greater than 50+ 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 on the machine for a long time. Package includes: 1 x Bluetooth Amplifier Board 1 x Shell 1 x DC Head Line 1 x Heat Sink(with 3M glue)
