Description

Class D 2x20W amplifier - Bluetooth 4.0

Luxus Audio - AMB2020NJ

AMB2020NJ 2x20W audio amplifier card with Bluetooth module. It has a 20W architecture (based on MAX98400A) and each channel has a power of 20W. Both channels are able to output nominal power simultaneously and continuously. This card can be powered by any DC10V-24V power supply. It can be used to drive two passive 8Ω speakers. AMB2020NJ can also be connected with our TSA1000, TSA1010 or TSA1020 external audio volume control card. People can adjust the audio volume by turning the actual knob.

It perfect for your Hi-Fi application. You may want to associate mobile phone or computer (etc.). Power the amplifier board. Use your phone or PC (etc.) To search for a new Bluetooth device. The module will appear as "TSA9840". You dont need to PIN, match it and then you can listen to music.

• AMB2020NJ can automatically detect the Aux / Line input in the audio input. The Bluetooth audio source has a higher priority. When Bluetooth audio is paused or bluetooth is disconnected. The amplifier will output the Aux in / Line audio.

• There is an extra LINE OUT audio output jack. It is also possible to connect to a subwoofer amplifier board.

• BVC port: the BVC port can be connected to our audio volume controller to control the Bluetooth audio volume.
