D*AP8 MAP

Block diagram
The above schematic shows the principal blocks of a fully loaded MAP.
The core of the unit is the audio processor. It has 2x eight inputs, eight outputs and a 2ch downmix
AUX output. It controls the speaker setup and settings during the monitoring session.
The device also provides the measurement data (true peak, level, loudness) for external applications like the
J*AM (Junger Application Manager) for logging and/or display on a PC or tablett screen via the Log Ports.
The Dolby Metadata Emulation is a hardware option that comes with the Dolby decoder. It is a functional
block that may be connected to the respective audio input / output signals via the device router.
Same applies for the metadata pathes that must be routed separately.
A Dolby encoder may be fitted as an option as well to provide encoded output to save the customers rack
space and installation cost.
On the motherboard you will find 4x AES3id I/Os which are bridged by relays in case of a power failure.
This hardware fail-over may be disabled for each I/O pair by internal jumpers.
Two interface slots which may carry option boards allow for extremely flexible interfacing of the MAP.
One of the interface slots will normally be equipped with an 8-channel analog line output board for direct
speaker connection while the other willl normally hold a 3G/HD/SD-SDI option board for TV production
applications.
For comprehensive metadata processing the unit has serial metadata I/O connectors. All metadata functions
are centralized in a metadata generator. Furthermore you will have the possibility to emulate the influence of
Dolby metadata on the audio signals for stereo or surround signals and down mixes, without the need to
involve an encoder and decoder.
The sync circuit can deal with all formats to integrate the device into digital facilities. Other devices may be
synchronized via the word clock output of the MAP. The frame reference for D-E encoding, may be shifted to
align the D-E guard band.
The MAP has eight balanced GPIs and eight SSR closure GPOs. This enables the user to simply recall
presets or call events, change device configurations and report general status information.
