Description
Product Resume
This product integrated with TDA7492 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. Besides traditional RCA input jacks, a stereo phone jack is provided to make it much easier to be used with your second device such as mobile phone or portable players. A high quality headphone amplifier is also provided at the front panel. It supports dual-channel amplification and each channel is rated at 50W. With built-in MCU, this product can provide input/output auto-override, over/under voltage protection, low current protection and display LED state.
