Prodys, Quantum Nerea 3U Rack System

Prodys Quantum Nerea Rack System takes up to 14 IP Codecs – Dante/AES67 Option

Quantum Nerea. Overview.

Quantum Nerea is an IP Multicodec in a 3U rack, which can house up to 14 IP audio modules codecs over IP.

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

Each Quantum 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 centralised 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 Nerea. Feature List.

  • Configurable and scalable system : Up to 14 IP modules. Cards can be hot swapped for servicing or maintenance.
  • Bonding and Diversity enables streaming of STL-grade audio quality over inexpensive links.
  • 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.
  • Additional LAN Management port to split audio and control data flows.
  • Call facilities: Auto-redial, call scheduler and log systems.
  • 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.
  • Optional Dante/AES67 module to provide an interface for uncompressed digital audio in a single Ethernet cable.
  • Up to 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.
  • Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility. Factory software upgrades can be downloaded.
  • Alarms: Real Time alarms management through SNMP traps, GPO and e-mails
  • AC or DC Redundant Power Supply.
