Prodys, Quantum One

Quantum One is an IP Multicodec in a 1U rack, which can house up to 4 IP audio codec modules over IP


Quantum One. Overview.

Quantum multicodecs offer the possibility of extending the number of audio signals provided by a single Quantum ST codec, inheriting all its key features such as its widest range of audio compression modes, stability, flexibility and easiness to use.

Each Quantum One module has two Ethernet ports allowing bandwidth aggregation (Bonding) and redundant transmission (Diversity). A third Ehernet port is used to support individual remote control of each audio module via embedded web server or centralized management via ProdysControlPlus..

An optional Dante/AES67 module is available to provide an interface for uncompressed digital audio over a single Ethernet cable replacing all the individual audio inputs and outputs.

Quantum One. Feature List.


  • Analog and Digital AES/EBU stereo audio I/O.
  • Optional Dante/AES67 module to provide an uncompressed digital audio interface in a single Ethernet cable.
  • Support Mpeg1/2 LayerII, AAC, apt-X, G711/G722, OPUS and PCM.


  • 2x Ethernet interfaces to make bonding or diversity transmissions. This enables streaming of STL-grade audio quality over inexpensive links.
  • Additional LAN Management port to split audio and control data flows.
  • Call facilities: Auto-redial, call scheduler and log systems.
  • IP Compatibily: support SIP/SDP/RTP/STUN protocols according the standard defined by EBU’s N/ACIP group.


  • Configurable and scalable system : Up to 4 IP modules. Cards can be hot swapped for servicing or maintenance.
  • Each module can be controlled remotely from its Web Page or from ProdysControlPlus.
  • Automatic detection of the encoding mode used by the remote unit.
  • Independent encoding/decoding operation.
  • 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 through SNMP traps, GPO and e-mails.
  • One user configurable general purpose input-output (GPIO). The input can be set up to control audio inputs or reset alarms, and the output can be configured to monitor different parameters.
  • Serial Port to transmit/receive auxiliary data along with the audio.
  • Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility. Factory software upgrades can be downloaded.
  • AC or DC Redundant Power Supply.
