Sonifex PS-AMP - IP to Speakers Streaming Decoder

Sonifex PS-AMP

The Sonifex PS-AMP is a freestanding unit which converts an IP audio stream directly to speaker outputs.  The PS-AMP uses an integrated 2 x 15W D-class amplifier to deliver audio directly to a pair of connected speakers.

The PS-AMP has the same feature-set as the PS-PLAY except that there are no individual audio outputs other than the speaker terminals.
