Quantum2 XL
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.

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.
