Product Overview
Material: PCB
Purpose: Power amplifier board
Model: ZK-502C
Chip: TPA3116D2 (with AM interference suppression function)
With or Without Filter: Yes (the sound is more round and clear after filtering)
Adapted Power Supply Voltage: 5-27V (you can choose 9V/12V/15V18V/24V and other adapters, high power recommended high voltage)
Adapted Speakers: 30W~200W, 4Ω-8Ω
Number of Channels: Left and right dual channels (stereo)
Bluetooth Version: 5.0
Bluetooth Transmission Distance: Approx. 15meter / 49.2ft (unobstructed)
Protection Mechanism: Overvoltage, undervoltage, overheating, DC detection, short circuit protection
Power Supply Voltage:
12V 8 ohm speaker/12W (left channel) + 12W 4 ohm speaker/20W + 20W (right channel)
15V 8 ohms/18W + 18W, 4 ohms/more than 30W + 30W
19V 8 ohms/32W + 32W, 4 ohms/more than 45W + 45W
24V 8 ohms/38W + 38W, 4 ohms/more than 55W + 55W
Tip: If the audio input is sufficient and the power supply voltage and current is sufficient, there is enough output power. The higher the power supply voltage, the greater the relative power. Speakers with different impedances will have different output power. In the case of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative sound power. Please make sure that the power of the adapter is greater than the actual working power of the amplifier.
Features
1、Potentiometer Control Volume: Potentiometer works for adjusting the volume, come with switch, convenient to control the volume, very suitable for DIY speakers
2、With Filter Inductor: Amp board come with filter inductor, the sound is round and clear, very practical
3、1.2MHZ Modulation Frequency: TPA3116D2 is a class D power amplifier IC launched by for TI, with very high index parameters. Up to 1.2MHZ modulation frequency, high power output distortion is less than 0.1%
4、2 Input Methods: With AUX and Bluetooth two audio source input methods, two in one, convenient to use
5、Higher Efficiency and Longer Distance: 5.0 Bluetooth version possess higher transmission efficiency, longer transmission distance
