CS-80 Bluetooth 5.0 hifi high-power module Amplifier finished board stereo 80W  This is a stereo, up to 80W output high-efficiency class D audio power amplifier circuit. Advanced EMIfD system technology allows the use of inexpensive ferrite bead filter in the output port The EMC requirements can be met by using a cheap ferrite bead filter at the output port. The power amplifier is designed for systems requiring high quality audio power output. The power amplifier is designed for systems that require high quality audio power output, using surface mount technology, and requires only a small number of peripheral components to make the system The power amplifier is designed for systems that require high quality audio output power. The amplifier chip itself has built-in over-current protection, short-circuit protection and over-temperature protection, which effectively protects the chip under abnormal operating conditions. protects the chip from damage under abnormal operating conditions. It can drive up to 40 loads of speakers, up to 80W continuous power; with up to 92% efficiency, the allowing for music playback without additional heat sink. Large supply voltage range of 5V~24V Up to 92% efficiency, no heat sink required Spread Spectrum Function Audio system with filtering network, standby current less than 20mA No filtering function Good short circuit protection and temperature protection with automatic recovery function Good distortion and anti-poof function Differential input Product information: Brand: BRZHIFI Model: CS-80 amplifier board Bluetooth version: 5.0 Transmission distance: 15m (unobstructed) Power supply voltage: DC5-24V Adaptable speaker: 10W-200W 408Q Size: 80*75*18mm Protection mechanism: power reverse protection, short circuit protection, self-recovery overheating protection 24V@RL=4Q 80W+80W 21V@RL =4Q 64W+64W 24V@RL=8N 42W+42W 21V@RL =8133W+33W 18V@RL=4Q 47W+47W U disk lossless format support: MP1/MP2/MP/3/WMA/WAV/APE/FLAC Audio input: AXU / computer / U disk / Bluetooth Note: The output power of the power supply should be greater than the output power of the power supply, otherwise it will affect the sound quality Recommended 6V or more power supply Package: 1pc CS-80 Bluetooth 5.0 hi-fi hifi high-power module amplifier board finished stereo 80W.
