D*AP8 MAP - 8 Channel Surround Monitoring Audio Processor Overview
One D*AP8 MAP can replace up to seven no longer available Dolby® processors in one easy to operate unit.
Aimed at providing comprehensive quality control and loudness monitoring for anyone working in a production or broadcast environment, the D*AP8 MAP is the only Loudness processor on the market capable of covering a full Dolby® workflow and offering real-time metadata emulation as standard.
Its user interface combines loudness and dialnorm measurement, metadata emulation and setup and monitor control on one web page. It is optimized for mouse or touch operation and can also be used as a day-to-day interface, for example on a tablet computer. This significantly simplifies workflows, especially for those familiar with Dolby®’s in 2013 discontinued DP570 Multichannel Audio Tool.
The D*AP8 MAP 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.
D*AP8 MAP - 8 Channel Surround Monitoring Audio Processor In Depth
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.
accessDP - The Dolby Workflow Interface
The optional Dolby® Decoder makes the D*AP8 MAP 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 accessDP user interface, 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. AccessDP is a true Dolby Workflow Interface!
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.
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.
The D*AP8 MAP user interface combines loudness and dialnorm measurement, metadata emulation and setup and monitor control on one web page. It is optimized for mouse or touch operation and can also be used as a day-to-day interface, for example on a tablet computer. This significantly simplifies workflows, especially for those familiar with Dolby®'s discontinued DP570 Multichannel Audio Tool.
