Оригинальное описание Dolby® DMA8Plus Digital Media Adapter:

Equip your sound system for digital cinema with the Dolby DMA8Plus Digital Media Adapter.

The Dolby® DMA8Plus Digital Media Adapter is a practical, flexible solution for equipping your sound system for digital cinema, onscreen advertising, special events, and other program sources using digital audio. The adapter provides a comprehensive audio interface while its automation intelligence maintains a seamless fit with your cinema processor. The product design is elegant yet rugged and compact, occupying only one rack-unit space.

The DMA8Plus has four separate digital inputs and will 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.

The DMA8Plus is easily set up via a laptop computer, and can be controlled by your cinema’s automation system via standard GPIO automation, serial, or Ethernet commands. Individual digital sources can be selected rapidly using dedicated front-panel buttons. The unit also provides a switched “through” connection for external film audio decoders or six-channel analog sources such as the Dolby 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 often require different delays.

The front panel is designed to provide a wealth of feedback and usability for the user. 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.
