    PYKO-IN - Overview

    Digigram PYKO-in is a stereo IP audio encoder that can be used in two modes. One mode allows converting the analog audio source into an IP audio stream sent to one or several destinations. Typical applications include STL, WEB radio encoding, background music, and paging. Combined with PYKO-out, PYKO-in is a cost effective solution for establishing IP audio links. Another mode allows using PYKO-in as a mono encoder/decoder; typical applications include intercom over IP.

    At a glance
    PYKO-in is a small form factor rack-mountable stereo IP audio encoder or mono IP audio codec, depending on the way it is configured. Used as a stereo encoder, it features two balanced analog mono inputs. Used as a mono codec, it features one balanced analog mono input and one mono balanced mono output. One of the inputs offers a microphone preamp with phantom power, which is useful when PYKO-in is used for intercom. PYKO-in generates standard RTP streams in G711, PCM, or MPEG L3 audio format and allows for auxiliary data tunneling (serial data and 4 GPI statuses).

    Stereo IP audio encoder, or mono encoder/decoder with mic preamp
    Standard RTP streaming
    WEB radio encoding: Icecast/Shoutcast, MPEG L3
    Control and monitoring through WEB pages, monitoring via SNMP

    Low price for an STL, or for a WEB radio encoder, but still with high audio quality
    No need for external mic preamp for intercom
    No need to be highly skilled to install and configure it
