The D*AP4 LM EDITION focuses on automatic and adaptive loudness management compliant with all current broadcast audio loudness recommendations including ITU-BS.1770 standards (revisions 1, 2 and 3) as well as recommended practices ATSC A/85 (2011/2013), ARIB TR-B32, Free TV OP-59, Portaria 354 and EBU R128.
The DAP4 LM EDITION features loudness normalization and dynamic range processing for up to two stereo programs of audio. Sophisticated fail over and voice over round off the DAP4 LM EDITION feature set.
Dynamic Range Control and Level Magic II™
Based on a unique multi-loop control principle, Jünger Audio’s Level Magic II™ algorithm offers adaptive wideband control with exceptionally high audio quality and without any coloration, pumping, distortion or modulation effects. The dynamics section comes with an expander and upward compressor. Level Magic II™ – uncompromised loudness management by combining three major gain changing elements:
• Transient Processor
• Adaptive AGC
• Distortion-free true peak limiter
Jünger Audio’s Spectral Signature™ dynamic equalizer gives you a powerful creative tool to control the spectral balance of your program. Spectral Signature™ analyzes incoming audio and compares its spectrum with a predetermined reference curve. This allows dynamic EQ corrections to be applied, if necessary, to achieve a consistent sound impression. Spectral Signature™ is an optional feature for the D*AP4 LM EDITION.
To check compliance of programs with your local loudness regulations the unit analyzes loudness and true peak levels from input signals and transfers the measurement data via Ethernet to an optional measurement and logging software anywhere in your network. These measurements can be triggered by automation systems via GPIs, via network or even manually on the XAP RM1 remote panel. The DAP4 LM EDITION can also generate SNMP or GPI/O alarms in case pre-determined limits are exceeded.
The optional Loudness Logger software allows for long term program logging and analysis. System Integration All system parameters are remotely accessible allowing the unit to be integrated and remotely operated by broadcast control systems. This helps users to apply individual processing to their programs, which is a key feature for well-managed loudness control.
A web interface allows easy and intuitive setup and configuration anywhere in your network.
Interfaces and System Security
Audio I/Os range from onboard AES I/O to optional 3G/HD/SD-SDI I/O including video delay and analog I/O. All combined I/O interfaces support power fail bypass as standard. With redundant PSU and SNMP integration the unit ensures maximum operational safety.
