Dolby® Digital Media Adapter DMA8Plus
Four digital inputs accept up to eight channels of PCM digital audio as well as Dolby Digital and Dolby E bitstreams. Two-channel audio sources can be decoded as discrete L/R, Dolby Pro Logic, or Dolby Pro Logic II. Analog audio outputs are calibrated to cinema processor reference levels to ensure a straightforward interface with your cinema's existing sound processor.
Easy to set up via a laptop computer, the Dolby DMA8Plus can be controlled by your cinema's automation system via standard GPI/O automation, serial, or Ethernet commands.
Includes a switched "through" connection for external film audio decoders or six-channel analog sources such as the Dolby Digital Adapter DA20. (In this way, both the DMA8Plus and the DA20 may share the cinema processor's six-channel input format.)
A separate adjustable global audio delay is assigned to each digital input to ensure that sound and picture are perfectly synchronized during digital cinema presentations. Different delays can be assigned to different inputs, giving flexibility with alternative content sources that require different delays.
The front panel is designed to provide a wealth of feedback and usability. Simple manual control is provided by the four digital input buttons and one film pass-through button. The valid indicators verify digital signal presence on each associated input. Other indicators reveal the bitstream format, the Decode mode, and eight-channel analog output signal presence. A USB port provides a reliable PC connection for the setup software application.
