Features The DDE51 was at introduction the first modular Dolby Digital Pro encoder in the world. Targeted at transmission environments the DDE51 has all the advantages of the Synapse system, such as hot swap ability, redundant power supplies, SNMP compatibility and a host of other modular solutions that fit the same chassis. The DDE51 is a functional equivalent to the DP569 from Dolby Laboratories.

Preset based meta-data insertion Dolby Digital encoding or bypass mode (individual for both outputs) Adjustable encoding data rate (56 kb/s to 640 kb, part of 8 presets) Full 8 channel independent input selection Built-in generator per mono channel Input gain control per individual mono channel Input phase control per individual mono channel Input offset delay for phase compensation (0 to 1300 ms in 1 ms intervals) Auxiliary output can source a second AC3 stream or a copy of each input Up to 18 AC3 pro encoders in 4RU Metadata input 5.1, 4.0, 3.1, 3.0, 2.0, 1.0 modes GPI triggered preset Status information of each input (including clipping) Encoder OK status reporting AES/EBU in and outputs on 75 Ohms BNC according to AES3ID-1995 Locks to Black & Burst, wordclock, AES input or Mastercard Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18

Complementary cards:

DBD08 HDE10

Note: The latency of the DDE51 has been 200ms, but has recently decreased to 166ms with latest firmware updates. In the future the latency will be user definable in the menu of the card.
