Module Power Rating:
This module is ideally suited to adding a bit of amplification to your audio outputs. Connecting your audio inputs and a separate power 5V supply allows you to amplify 2 separate channels of audio in preparation to be connected up to speakers. This module is ideal for situations where a device is unable to drive with sufficient volume or in instances where an audio signal has been split across multiple outputs, such as using a splitter.
This module will require soldering to your desired connectors however large hand solder friendly well labelled holes are provided.
As with all audio devices, noise can and will come from all manner of sources. To minimise the noise added through the amplifier a clean power source should be used. If you are unsure, connecting a 470µF Electrolytic capacitor to either side should help cut it out.
DO NOT CONNECT THE TWO NEGATIVE OUTPUTS TO EACH OTHER – THIS WILL DAMAGE THE UNIT
