Digigram PYKO OUT Stereo IP Audio Decoder

Key Workflow: audio over IP decoder for entry range studio to transmitter links (STL), as well as paging, background music, and live announcement applications

PYKO-out is a small form factor rack-mountable stereo IP audio decoder. It features two balanced analog mono outputs and a USB port for storing local playlists on a USB memory stick. It decodes standard RTP streams in G711, G722, PCM, MPEG L3, or AAC-LC and HE AAC audio formats and allows for auxiliary data tunneling (serial data, and 4 GPI statuses). PYKO-out also offers three decoding priorities with automatic failover, and can be remotely controlled through ASCII commands sent through TCP.
