Digigram PYKO OUT Stereo IP Audio Decoder

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.

Stereo IP audio decoder
Decoding of standard RTP streams and WEB radio streams (Icecast/Shoutcast)
USB port for storing local playlists on a USB memory stick for local backup
Three decoding priorities with automatic failover
Control and monitoring through WEB pages, ASCII commands over TCP, and monitoring via SNMP
