Speaker mini amp.

Post by erzane » January 20th, 2019, 12:32 am

I 'd like to buy this mini amp & replace my actual mono speaker by doing this (pls see drawing).
What's your advise on this, how should I proceed to wire it?

It's pretty simple and I'm sure it's been explained a thousand times on this forum.

You need an attenuation circuit if you're going to use regular jamma boards as the audio is already amplified. Basically in its simplest form it's just a voltage divider. Look up Google for passive audio attenuation. Alternatively get a high to low converter. It's like 5-10 euros, 20 for a "good one".

Take 12V from the extra 12VDC output on the PSU. Connect it to the amp. Take your new line level audio and connect it to the audio inputs on the amp. It looks like the amps you linked to have normal 2.5mm headphone jacks for that.

Connect your speakers to the L and R terminals, positive terminal to positive, negative to negative. If you got a subwoofer and you bought the amp that outputs 2.1, you can connect your sub to the sub output.
