D*AP8 TAP EDITION Digital Audio Processor
This creative toolset is based on the processing platform D*AP8 and designed to make your transition to loudness controlled broadcasting smooth and easy. With 8 processing channels, 3G SDI, Dolby® support and optional loudness logging features, the D*AP8 TAP EDITION covers every requirement broadcasters are facing today.
Jünger Audio’s award-winning D*AP8 TAP EDITION audio processor focuses on automatic and adaptive loudness management compliant with all current broadcast audio loudness recommendations including ITU BS.1770 standards (versions 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 D*AP8 TAP EDITION audio processor features loudness control plus dynamic range processing for up to eight channels of audio (4x2, or 5.1+2). Optional audio decoding and encoding (Dolby® E, Dolby® Digital Plus, Dolby® Digital or AAC, HE-AAC v1/2) including metadata management are also provided, along with 5.1 downmix and upmix features, sophisticated fail over and voice over systems.
- Dynamic Range Control and Level Magic™
Based on a unique multi-loop control principle, Jünger Audio’s LEVEL MAGIC™ algorithm offers adaptive wideband loudness control with exceptionally high audio quality and without any coloration, pumping, distortion or modulation effects. LEVEL MAGIC™ - uncompromised loudness management by combining three major gain changing elements:
- • Transient Processor
- • Adaptive AGC
• Distortion-free true peak limiter
The adaptive dynamic section comes with an expander and upward compressor.
- Spectral Signature™
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 spectral structure with a predetermined “station sound” curve. This allows dynamic EQ corrections to be applied, if necessary, to achieve a consistent sound image. Spectral Signature™ is a standard feature.
- Loudness Measurement
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 DAP8 TAP EDITION can also generate SNMP or GPI/O alarms in case pre-determined limits are exceeded.
- Loudness Logging
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. Web Configuration A web interface allows easy and intuitive setup and configuration anywhere in your network.
- Interfaces and System Security
Audio I/Os range from on board AES I/O to optional 3G/HD/SD-SDI I/O including video delay and analog I/O. All interfaces support power fail bypass as standard. With redundant PSU and SNMP integration the unit ensures maximum operational safety.
