Digital Broadcast Step by Step

DB2 puts all of the tools necessary for trouble-free broadcasting into one rack-mountable unit, and adds to a scalable family of processors covering from regional stations to network centers, from Pod-cast to HDTV, from AC3 to linear, and from mono to 5.1.

  • Automatic Loudness Correction - Consistant Loudness without the Hassle
  • Compliant - ITU BS.1770, EBU R128, ATSC A/85, etc.
  • Upgradeable - If Your Needs Grow, Upgrade from DB2 to DB4 or DB8
The Transparent Loop

We are the world's premier supplier of automatic loudness correction equipment and our high-quality audio loudness range trickle-down concept works independently of metadata, but nevertheless is fully compliant with metadata in, for instance, the AC3 codec.

DB processors not only automate loudness control in a proper way, they also help take the extra workload and unpredictable behavior out of the codec.

Apply it in ingest and/or transmission as part of a transparent loop, based on international open broadcast standards, spanning from production over transmission to delivery at the home viewer/listener.

If you're in production, use one of our metering tools such as the LM6 radar loudness meter and obtain predictable results across broadcast platforms. News, soap, commercial, film, music, promo. All genres are covered.

The Tools

DB2 gives you a wide variety of connection options to ensure simple yet comprehensive integration into all of the most popular broadcasting systems. You can also remote control DB2 with our award-winning Icon software, allowing direct parameter control and preset switching from any location.

Based on an immensely powerful, low-latency topology, DB2 gives you a host of 48-bit resolution tools to be used simultaneously:

    •    5-band Level Optimization
    •    On-line Delay Adjustment
    •    Adaptive Limiting
    •    Emphasis Compensation
    •    Filtering and EQ
    •    Stereo Width Adjustment


Audio I/O include 24 bit AES3-id on BNC connectors and balanced analog on XLR connectors with analog domain gain scaling. Digital as well as analog I/O feature hardware bypass.

Remote control may be established via RS232, USB and/or GPI; and SNMP signaling is available via the Icon application.
