This module is ideally suited to adding a bit of amplification to your audio outputs. Connecting your audio inputs and a separate power 2 – 5.5V supply allows you to amplify an audio line in preparation to be connected up to a speaker. 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.
