8 Channel Surround CODEC Processor - D*AP8 CODEC

Developed in close cooperation with Dolby® Labs, the D*AP8 CODEC is designed to replace a wide range of legacy Dolby® processors wherever there is a requirement for decoding, encoding or transcoding of audio signals. Multiple audio I/O formats are supported including native AES along with optional SDI, MADI, DanteTM and analog.

    Designed for use in all areas of audio broadcast and distribution, Jünger Audio’s D*AP8 CODEC offers the functionality to decode and/or encode any current Dolby® audio bitstream and to effectively manage and emulate all Metadata parameters.

    • Overview

    The D*AP8 CODEC has eight channels of audio I/O (4x2.0 or 5.1+2.0) and built in Dolby® decoding with metadata management and emulation as standard. Optional Dolby® encoding is also available. Network based loudness metering and Voice Over are standard whilst logging, Upmix and Fail Over are optional.

    • Dolby® Decoding

    The Dolby® Decoder supplied with the D*AP8 CODEC provides decoding of the following Dolby® formats:

    • Dolby® E • Dolby® Digital Plus • Dolby® Digital • Pro Logic II (decode and encode)

    • Dolby® Encoding

    Optional Dolby® Encoders are available to provide either:

    • Dolby® E


    • Dolby® Digital Plus • Dolby® Digital • AAC, HE-AAC v1/2

    • Metadata Management and Emulation

    In addition to bitstream decoding, comprehensive Metadata management and emulation are standard features. The setting of Metadata parameters such as Dialnorm, Downmix and DRC are critical to ensure correct performance of the end user’s decoder. The emulation function enables values to be verified or adjusted in real time to be certain that the end user’s audio is reproduced correctly and appropriately for their listening environment.

    • Loudness Metering and Logging

    To ensure compliance with local regulations, loudness and true peak levels can be measured and transferred via Ethernet to the optional J*AM measurement and logging software. All current loudness standards are supported including ITU-R BS.1770 (1, 2, 3) and recommended practices ATSC A/85, ARIB TR-B32, Free TV OP-59, Portaria 354 and EBU R128. A real-time plot of input levels can be displayed and logged to a destination folder anywhere on the network.

    • Upmix/Fail Over/Voice Over/Limiting

    Voice over functionality is provided allowing for seamless integration of voice and program content with automatic ducking or mixing. Optional features offered through software licenses are Upmix to create 5.1 surround from native stereo audio, and Fail Over to facilitate automatic switching to a back up signal feed or bitstream should the primary feed be lost. True peak limiting is included as a standard feature.

    • Control and Configuration

    A web browser interface allows easy and intuitive setup and configuration of all the unit’s parameters from anywhere on your network, whilst a variety of on screen metering and measurements are available for easy reference. Most parameters are based on the principle of “set and forget” so with a small number of initial settings, the unit can be up and running on air within minutes. The optional X*AP RM1 Remote Panel provides 8 hotkeys along with metering and measurement displays.

    • System Integration

    For integration into an automated broadcast environment, all parameters are remotely accessible allowing the unit to be operated by external control systems and software. An advanced built-in Event Management tool allows the remote loading of parameter presets and settings either by hotkeys on the optional X*AP RM1 remote panel, by 8 onboard GPI/O’s or by network commands using the Ember+™ control protocol.

    • Interfaces and System Security

    Audio I/O’s range from on board native AES3 to optional 3G SDI including video delay, MADI, Dante™ audio over IP and analog. Two interface expansion slots are available to allow for back up input feeds or bitstreams. Power fail bypass relays are fitted as standard and with dual redundant PSU’s and SNMP integration, the unit ensures maximum operational safety and peace of mind for today’s critical 24/7 broadcast or content delivery facilities.
