The D*AP8 CODEC EDITION is one of the range of Jünger SLIM LINE broadcast audio processors: other models provide loudness management, audio monitoring and voice processing.
The D*AP8 CODEC EDITION is a 1U audio processor intended for use in broadcast installations where flexible control and monitoring of Dolby® encoded programme material is required.
The 8-channel base unit offers four AES3 inputs and outputs and decoding for Dolby® E, Dolby® D, Dolby® D+ and Dolby® Pro Logic II. An internal routing matrix allows emulation of consumer decoders and set top boxes with different metadata. Loudness measurement is included, and True Peak Limiting can be applied independently to the various output bitstreams.
The processor’s design allows additional functionality to be added to the base unit as required. This can be in the form of further I/O options via rear panel expansion slots, and also Dolby® encoding options via internal plug-in cards.
If SDI is the facility’s transport standard, one or two SDI I/O modules may be installed in the rear panel card slots. These cater for SD, HD and 3G formats and are compliant with SMPTE 424/425M, 292M and 259M. The CODEC EDITION can de-embed the 16 channels of audio and these can be routed internally to the Dolby® processors. De-embedded channels may also be routed to the unit’s AES3 outputs to feed external equipment. The SDI I/O module also supports embedding, allowing signals from elsewhere in the CODEC EDITION’s architecture to be inserted into the SDI stream for onward transmission. The outgoing SDI video can be delayed to compensate for internal audio processing.
The CODEC EDITION’s standard AES connectivity can be increased by adding an AES I/O module. This provides eight additional input and output channels (4 x AES3 in each direction), via a 25-way Dsub connector.
Two analogue I/O modules are also available: one has four line inputs and four line outputs, the other has eight line outputs. All inputs and outputs are balanced and capable of +24 dBu maximum level.
The range of Dolby® processing available in the CODEC EDITION may also be expanded by adding an additional internal option board. This may be a Dolby® E encoder, or a multi-format encoder which can generate a Dolby® D (Dolby Digital), Dolby® D+, AAC or HE-AAC stream.
When additional modules or option boards are installed, the audio routing matrix may be set to route any input to any processor, and to define the output sources in a similar way.
The CODEC EDITION can be remotely accessed in a number of ways: an internal web interface allows full configuration, control and preset storage from a browser on any compatible device connected to the Ethernet port. The unit is also compliant with the Ember+ broadcast industry network control protocol allowing connection to broadcast control systems. The Jünger X*AP RM1 Universal Remote Control Panel (applicable to numerous Jünger units) provides a dedicated hardware controller, which has the advantage of being able to interface to several processors simultaneously. A powerful event programming feature is included, allowing events to be triggered from the GPIO port or from keys on the optional X*AP unit.
An Upmix/Downmix/failover software licence option permits the CODEC EDITION to create a stereo downmix should the 5.1 surround signal fail. Similarly, a 5.1 upmix is created in the event of failure of the stereo output. The unit smoothly crossfades between the formats.
The unit provides continuous loudness measurement and makes the data available via the network port. The J*AM LoudnessLogger™ application may be installed on a suitable network device to keep a permanent record of levels, in order to conform with local Broadcast Authority practice. SNMP functionality is included as standard, allowing the unit to be connected to SNMP monitoring systems.
The CODEC EDITION has two internal power supplies as standard; each PSU has its own IEC inlet and power switch.
