Quantum2 W is a complete Commentary Unit including 3 mic/line inputs and 3 headphone outputs. Additional sources to its embedded mixers are USB Audio, AES/EBU or AoIP/AES67 (DANTE or Ravenna optional) inputs.

Quantum2 W is an all-in-one box solution for remote commentaries linking two bidirectional audio streams with four independent voices, sounds or mixed audios to the studio or Host Broadcast Center.

Perfect sounds are encoded using a choice of advanced and low delay compression algorithms for sport and music.

Highly reliable transmissions are achieved using Diversity and Bonded streams over a group of network interfaces (2x Ethernet, 2x LTE and Wi-Fi).

Additionally, a video downlink stream can be decoded internally and shown on a general purpose monitor, enriching the information supplied to the talents.

A video video uplink is also possible for the transmission of images from the commentators to the studio.

It also allows to insert audio into the received video and to forward  a single synchronised video and audio stream  to the studio.


  • 3 x Mic/Line Audio Inputs available to be mixed, encoded and streamed in Stereo mode.
  • Additional audio inputs: USB stereo, AES/EBU, Line.

  • Inherits world-class IP technology from the Prodys Audio/Video codec family:
    – Automatic Jitter buffer. This adjustable buffer avoids audio dropouts in the IP connection.
    – Automatic synchronization adjustment with the transmitter site rate, to give a constant delay in IP communications.
    – Prodys NAT Traversal Streaming Protocol permits router firewall pass-through with zero configuration.
    – Prodys Real time Network Analyzer: to monitor critical network parameters in real time during the connection.
    – FEC (Forward Error Correction). Up to 24 different schemes are available, to fit to the desired delay and available bandwidth.
    – Error Concealment mechanisms on Mpeg audio modes are supported to reduce the impact of packet losses.
