An inexpensive and compact converter

The Smart-AVI SMA-AD400S digital audio switch enables users to convert four digital audio signals to an analog stereo RCA and 3.5mm output, along with an SPDIF digital output. Today’s video and audio devices – including Blu-ray players, gaming consoles and others – often come with digital audio outputs. However, not all stereos, home theatres and PA systems are equipped for digital audio.

The SMA-AD400S is an inexpensive and compact converter that makes digital audio signals compatible with the most common analog audio connectors, RCA and 3.5mm. With four inputs, two outputs and a button for switching, this unit delivers lots of flexibility. The device is plug-and-play ready and small enough to fit nearly anywhere.
