WONDOM 2 X 50 Watt 6 Ohm Class D Audio Amplifier Board

Description: 2 X 50WATT CLASS D AUDIO AMPLIFIER BOARD - TDA7492（AA-AB32174）Picture Showcase Description This Class D stereo mid-power audio amplifier board employs TDA7492 amplifier IC as the driver and delivers 50W output power per channel into a 6Ohm load. It features high efficiency up to 93% and high sound quality with low distortion and low noise level. Easy installation, high reliability and mid power output makes this audio amplifier board suitable for home audio, DIY audio, desktop amplifier, toy audio and demanding industrial applications. A DC10 – 27V power supply is required.High Quality Audio PerformanceDue to the dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches 95.775dB and THD+N performs well as 0.041% @ 6Ohm, 1W, 1kHz.High Reliability and Long Service TimeAn optimal heatsink along with a low noise cooling fan is mounted atop the amplifier board to maximum the heat dissipation, which improves its stability. Mute and Standby functions are offered with this amplifier module for easy control. Full protection circuit, like over temperature protection and overcurrent protection, is equipped on this board for high reliability and long service time.Easy for InstallationFour screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. All the necessary terminals for power supply, audio input and audio output are pre-mounted on the board. Therefore, you only need to plug in the cables and enjoy music without any need of soldering. If you want all the terminals to be mounted for your applications, please contact us. MOQ would be required.Four Stages Gain AdjustableThis audio module provides four stages gain for customers’ choice as 21.6dB, 27.6dB, 31.1dB and 36.6dB. You can select the most suitable stage for your application. The switch among the four stages gain is achieved by the different combination of the two switches on the board, no need of complex operations.Package Includes1pc AA-AB32174 FeaturesOutput Power50W@6Ohm 24V DC THD+N 10%39W@6Ohm 24V DC THD+N 1%Power IndicatorGain AdjustableOvercurrent ProtectionOvertemperature ProtectionOptimized Heatsink DesignLow Noise Cooling FanWeight: 396g/0.87 lbs (±10%)Size: 4.80 x 3.60 x 1.53 inchesSpecification Specifications typical @ +25℃, powered by 24V DC, unless otherwise noted.
