Brief Introduction： This product integrated with TA2024 which is currently popular around the world, it not only provides dream sound but also has high efficiency, thus it can dissipate the heat after long-time working to ensure that the amplifier can works in a stable condition for long time.
AA-AS32157 integrates a high-quality rotary encoder which employs high-quality digital volume control IC ensuring precise shaft rotation and accurate volume adjustment. AA-AS32157 supports dual-channel amplification and each channel is rated at 15W. With built-in MCU, this product can provide over/under voltage protection, low current protection and display LED state.
This product can be powered by any DC power supply ranging from 9 to 14V. You can use it to drive any 4Ω or 8Ω passive speakers. Features: - Size: 6.4 inch x 2.9 inch x 1.9 inch
- Signal Noise Ratio: 90dB
- Power supply: DC 9V to 14V
Applications:- Home Theater
- Desktop Amplifier
- Powered DVD Systems
- Mini/Micro Systems
- MP3, Video CD output Amplification
