ZK-502H 2x50W HiFi 2.0 Dual Channel Speaker Digital Power Amplifier Board Wireless AUX Audio Stereo Bluetooth-compatible 5.0 Amp Feature: Chip scheme: TPA3776D2, with AM interference suppression function Protection mechanism: Overvoltage, undervoltage, overheating, DC detection, short circuit protection Supported audio input: Bluetooth-compatible 5.0, AUX, U disk, computer USB (U disk file system must be FAT 32, maximum support 32GB) Supported audio output: Active speakers, passive speakers (note: passive speakers and active speakers can only choose one) The power supply cannot be connected to the 24V battery pack (the actual maximum voltage of the 24V battery is about 28V Specification: Product name: HiFi level 2x50W Bluetooth-compatible 5.0 power amplifier module Product model: ZK-502H Chip solution: TPA3776D2 Audio source input: Bluetooth-compatible + AUX + U disk + computer USB sound card (plug and play) Adapter power supply: 9-24V (high voltage is recommended for high power) Adapted speakers: 10-100W; 4-8Q Number of channels: Left and right channels (stereo) Bluetooth-compatible: Version 5.0 (>15 meters, barrier-free) Product size: 60x60x29mm Product weight: about 68g Remind: Only when the audio input is enough and the power supply/current is enough, will there be enough output power. The higher the power supply voltage, the greater the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the horn ohm, the smaller the relative sound power, please pay attention! Voltage: 12V - 8 ohms/12W (left channel) +12W (right channel), 4 ohms/20W+20w 15V - 8 ohm/18+18W, 4 ohm/30+30W 19V - 8 ohms/32+32W, 4 ohms/40+40w 24V - 8 ohm/38+38W, 4 ohm/50+50w Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 X Power Amplifier Board 1 X Screw Fitting
