Leading the evolution of IP audio & video codecs since 1995

Quantum2 XL

Portable

The Prodys Quantum2 XL is a portable, all-in-one, broadcast-grade IP commentary unit designed to send high-quality, two-way audio and optional video from a remote location to a studio. It combines audio/video encoding, multiple network interfaces for IP bonding and diversity, a video decoder, and an embedded mixer to create a complete solution for on-site commentary, allowing for dual-language broadcasts, video return feeds, and advanced audio management using standard protocols like AES67 and SIP.

Key Features and Functionality

  • Audio and Video Capabilities:
    • Supports two bidirectional stereo audio streams.
    • Includes a video encoder for commentator cameras and a decoder to display return video feeds from the studio.
    • Can embed up to four audio channels within a single video stream.
  • Networking:
    • Bonds multiple network interfaces (Ethernet, LTE/5G, Wi-Fi) for reliable transmission with features like Forward Error Correction (FEC).
    • Uses Prodys’ NAT Traversal Streaming Protocol for seamless router pass-through.
    • Supports standard audio (AES67) and transmission (SIP) protocols.
  • On-Site Commentary:
    • Features 5 microphone/line inputs and 4 headphone outputs for commentators.
    • Can decode remote video streams, providing support for commentators who can’t see the entire event.
  • Advanced Features:
    • Automatic Jitter Buffer and synchronization adjustment for stable audio.
    • Uses advanced, low-delay compression algorithms for music and sports audio.
    • Supports various audio codecs including OPUS, AAC, and PCM.
    • Can be managed remotely via a built-in web server or the ProdysControlPlus application.

Features

COMMUNICATIONS

  • 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.
  • Bonding or Diversity with up to 7 IP links for secure audio streaming and the best audio quality possible.
  • 2 x Ethernet interfaces: Either to split streaming and control or for bonding/diversity with 2 IP links.
  • LTE/5G IP data links with bonding capabilities. 2 x Internal modem or External LTE/5G module with 4 modems.
  • Wi-Fi interface 802.11b/g/n compatible Bonding with Ethernet or LTE/5G.
  • IP Compatibility: SIP/SDP/RTP/STUN protocols are supported according to the standard defined by the N/ACIP project within the EBU group.
  • Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility. Factory software upgrades can be downloaded.

OPERATION

  • User friendly interface via touch panel, built-in Web Server or ProdysControlPlus application.
  • User Access Control to define different access restrictions in a per user basis.
  • Configuration presets to define different configurations for all or some specific parameters.
  • Alarms: Real Time alarms management.
  • Serial port to transmit/receive ancillary data along with the audio.
  • GPIO port: 2 inputs/outputs. User configurable with multiple functions such as remote contact closures.
  • Long duration battery with charge and status indications. It can be charged on system.
  • Internet Sharing, so external devices can access the Internet through a Wi-Fi hotspot.
  • Ethernet Tunnel to link two remote local networks.
