The Atomic SPK Base is an audio player specifically designed to work with Atom Lite and AtomS3 Lite. It has the NS4168 power amplifier chip which features a built-in I2S digital audio interface. This setup supports automatic sampling rate detection and adaptive functionality to minimise audio signal distortion, providing high-quality playback. Additionally, the device includes a Micro SD Card slot for easy storage and retrieval of audio files. It is equipped with a 3.5mm headphone jack and an external speaker interface, providing listening options through either headphones or external speakers. Note: The Atomic SPK Base may experience IO conflicts when used with the ATOM Matrix due to compatibility issues with the built-in hardware of the latter. Therefore, the base is recommended solely for use with ATOM LITE and ATOMS3 LITE models.
