CentIoT - Digital Audio Amplifier Module - Class D - 2 X 50W Stereo

Brand: CentIoT

Features:

• Dual Channel 50W per Channel - Dual-panel wiring, properly solve the crosstalk between the ground potential balance and channel wiring
• Unique with LC filter Class D digital power board, and can be used directly to the computer's USB powered.
• Power supply: DC 12-24V, Recommended voltage: 12 V, Quiescent current: 20 mA, Rated output power: 50 W +50 W (8)
• Excellent noise suppression in the case is not connected to the input audio, the ear close to the speaker can not hear any noise
• Frequency response: 20Hz to 50KHz; High power class D digital amplifier board Using TPA3116 chip

PartNumber: CLASS-D-2X50W

Details: Dual channel stereo output 50 w + 50 w power Class D Works with 12v power supply High amplification efficiency 85% can directly drive 4 Ω/8 Ω small speakers to medium speakers. Good sound quality & noise suppression. Common Issues 1. Not getting full sound The output power of power supply should be higher than or equals to the total power of amplifier board if you want the amplifier to run in full power. For example, if your amplifier is 2 * 50 = 100W, you will need a 200W power supply. 2. Humming Sound Issue A humming sound in an amplifier's power supply is often caused by a ground loop, a poor grounding connection, or a faulty filter capacitor. Other potential causes include problems with the transformer or rectifier, as well as the proximity of power and signal cables 3. Power on Pop Sound A "thud" sound when turning on an amplifier, often a thump or pop, is usually caused by a momentary DC voltage surge at the output due to the power supply charging capacitors. This can happen because the amplifier's power supply may be charging one side of the voltage rails faster than the other. It can also be caused by a faulty power switch or a DC offset at the amplifier's output Solution This amplifier module is not an finished product, hence it needs additional power supply filters and protection circuits, recommended to use good quality power supply with proper filters and delay start mechanism to prevent potential speaker damage. Minimum heatsink of size 50x50mm or above is needed to dissipate heat and prevent thermal runaway.
