8 Channel Surround Monitoring Audio Processor Edition - D*AP8 MAP EDITION

The D*AP8 MAP EDITION is a multi purpose audio device comprising of an 8 channel audio monitor, an optional comprehensive Dolby® toolkit including metadata emulation, along with full loudness metering and logging capabilities. Supporting SDI, AES, MADI, Dante™ and analog I/O, the unit can handle any audio format from mono to 7.1. With firmware version 3.0 a new Mobile UI for metadata handling and monitor control will be introduced.

    Aimed at production, QC and live broadcast applications, Jünger Audio’s D*AP8 MAP EDITION is a monitoring audio processor especially suited for use in OB trucks where it can serve as an ideal replacement for the discontinued Dolby® DP570 Multi-Channel Audio Tool through the addition of the optional on-board Dolby OEM decoder.

    • Overview

    The D*AP8 MAP EDITION audio processor features control and monitoring for up to eight channels of audio (4x2.0, 5.1+2.0, or 7.1 speaker configurations). Optional audio decoding and encoding (Dolby® E, Dolby® Digital Plus, Dolby® Digital or AAC, HE-AAC v1/2, Pro Logic II) including full metadata management and emulation is available, along with 5.1 and 2.0 downmix. Network based loudness metering and optional logging complete the main feature set.

    • Monitoring Controller

    Selectable Primary and Secondary inputs allow easy switching between source signals for monitoring and auditioning of either surround or stereo mixes. A full downmix process facilitates monitoring of 7.1 – 5.1 or 5.1 – 2.0 to ensure predictable results for all end user speaker layouts. A speaker control section provides volume, solo, mute and matrix re-mapping for critical evaluation of audio quality from any channel to any speaker when used with the optional analog out board. The output section features full bass management for simulation of speaker configurations with or without subwoofers. Also included is a powerful 5-band parametric equalizer featuring full control of filter type, frequency, gain and Q factor. The final output stage includes speaker attenuation and a true-peak brickwall limiter.

    • Dolby Processing with New GUI

    The optional Dolby® Decoder makes the D*AP8 MAP Edition the perfect choice for broadcast applications where the audio will be transmitted in either Dolby® Digital or Digital Plus formats, as it provides metadata emulation. 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 and the resulting audio auditioned in real time to be certain that the end user hears exactly what the mixer intended.

    With the new Mobile UI Dolby® Metadata control and emulation becomes even easier. All relevant parameters are clearly arranged together on one screen. The new window is optimized for touch control and gives access to many parameters in daily use. Inspired by the features of the original Dolby® devices DP570 and LM100, users will instantly recognize the familiar, yet further improved design.

    • Loudness Metering and Logging

    For compliance with local regulations, loudness and true peak levels can be measured and transferred via Ethernet to the optional JAM 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. A log file analyzer rebuilds the original plot for easy readout of historical data, whilst a log port router allows the JAM software to display up-to four measurements.

    • Control and Configuration

    A web browser interface allows easy and intuitive setup and configuration of all the unit’s parameters anywhere on your network, whilst a variety of on screen metering and measurements are available for easy reference. The optional X*AP RM1 Remote Panel gives direct control of volume, dim and speaker muting and includes a fully featured loudness meter display.

    • System Integration

    For integration into an automated production 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 example digital audio in, and analog audio out, to drive monitor speakers directly. With dual redundant PSU’s and SNMP integration, the unit ensures maximum operational safety and peace of mind for today’s critical production or broadcast monitoring applications.
