Good morning,

I’m involved in a project making a little sistem that must have a jack aux-input and play music with audio mono (only a speaker).

I sow this amplifier:

DROK® Mini TDA7297F Stereo Audio Amplificatore Elettronica fai da te Portatile Digitale AMP Modulo 15W +15W Dual-Channel 12V DC Classe D Amplifier Board

to be coupled whith this speaker:

DROK® 15W Mini 3 “Speaker pollice 4 Ohm HiFi Full Range Audio 2.0 / 2.1 stereo di casa Woofer Altoparlante 90dB

Do I need some other component (in addition to DC in and music source with headphone out) to produce music?

Thank you in advance,

Gianluca Venturi

Hello Gianluc,
Thanks for writing in.
Without ASIN number or product link, we can’t ensure the items you mention.
We find out this amplifier and speaker. 090154
110031
Is it right?
This amplifier has audio input socket. And you can just connect one channel to play music with audio mono.The other channel is disconnected in that case.
If you don’t have suitable powr supply, we suggest you can choose the other amplifier with power adapter.110043
Best regards.
