Description

PYKO-out Stereo IP Audio decoder

 

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

FEATURES

 

  • Two balanced analog outputs (+18 dBu)
  • One 10/100 Mbits/s Ethernet RJ-45 port
  • Supports the following audio formats: G711, G722, PCM, MPEG L3, and AAC-LC and HE AAC at 32 kHz
  • Standard RTP streaming, or Icecast/Shoutcast
  • Auxiliary data tunneling (serial data through RS232 port, 4 GPIOs)
  • Unicast, multicast, multi-unicast and multi-multicast (up to six destinations)
  • Configuration and monitoring from WEB pages, or through ASCII commands via TCP
  • Possibility to start/stop the stream via GPIs
  • Front panel headphones mini-jack
  • External power supply
