TDA7492P digital amplifier board module designed based on dual BTL class-D audio amplifier. This single power supply module designed specifically for LCD TVs and monitors. This module consists of an integrated onboard Bluetooth module, all the used components in the amplifying process. Along with it an output connectors, and control buttons. By providing an input of 12V to 36A, an 8-ohm 50W speaker to each output and connect to a Bluetooth device, we can enjoy the magic of this digital audio amplifier board. It supports Wide-range single-supply operation of 8V – 26 V providing efficiency of 90%.TDA7492P digital amplifier board module has 5 control buttons. These control buttons are used to change the track or control the volume. Meanwhile, the DIP 2 switches button functions as Combining the up/down position of each switch you can obtain 4 different filters for the output.
This Amplifier generates an Audio stereo input and connectivity to all versions of the Bluetooth connection, using CSR8635 Bluetooth chip with Bluetooth V4.0. The module is capable of providing an Output Impedance of 8 ohms per channel. This amplifier module with a TDA7492 digital amplifier chip, designed specifically to optimize the circuit layout, better sound quality. Moreover, the big power DIP switches adjusted directly after the amp gain more respect and better promote greater damping horn.
TDA7492P digital Bluetooth amplifier module supports a range of up to 5m. Whereas beyond 6m, the connection became intermittent. This amplifier also allows selection of four fixed gain 21.6dB, 26.6dB, 31.1dB, 33.6dB.settings via DIP switch selection.
