Program Play

Enable: Allows the input to Main In to vary from the nominal 48 kHz sample rate. Permits the decoder to operate with a VTR in Program Play mode. As the sample rate varies from 48 kHz, the decoding latency is no longer exactly one video frame. The P in the display below reflects that Program Play is enabled.

Disable: The sample rate of the Main In input must be 48 kHz for the DP572 to decode.

48 kHz Pull Down

See 48kHz Pull Down on page 3-10.

PCM Bypass

Enable: Allows smooth transitions between decoded Dolby E and PCM audio.

Disable: Audio outputs are muted until a valid Dolby E stream is received at the Main In input. This is useful when editing on a VTR while decoding with the DP572.

Bypass Metadata

This feature is only relevant if PCM Bypass mode is enabled.

Disable: While the DP572 receives PCM input, no metadata is output.

Enable: While the DP572 receives PCM input, a default set of metadata parameters more appropriate for two-channel audio is sent instead of the Dolby E stream’s metadata.

These devices are designed to enhance the overall sound experience in theaters, auditoriums, and other large venues, making them crucial for delivering high-quality audio.

The Dolby DP572 is a multi-channel audio processor that supports 7.1 surround sound configurations. It is equipped with advanced Dolby technologies, including Dolby Digital, Dolby Digital Plus, and Dolby TrueHD. This versatility allows filmmakers and sound engineers to create immersive soundscapes that bring an added layer of realism to the viewer's experience. One of the salient features of the DP572 is its advanced processing capabilities, which include automatic calibration, loudness control, and extensive equalization options, ensuring that the sound quality is optimized for any environment.

On the other hand, the Dolby DP571 is a companion processor designed primarily for applications that require flexible audio routing and management. It features the same high-quality audio processing as the DP572 but focuses more on signal management, making it ideal for venues that may need to adapt their audio setup frequently. The DP571 supports both analog and digital audio inputs and outputs, providing versatility for various sound systems. Both units feature user-friendly interfaces, making them accessible for system integrators and operators alike.

In terms of connectivity, both processors boast multiple inputs and outputs, allowing seamless integration with existing audio systems and peripherals. They also support industry-standard audio formats, making them compatible with a wide range of content sources. Signature Dolby technologies, such as dialogue enhancement and surround sound synthesis, ensure that even the most complex audio tracks are rendered with precision.

In summary, the Dolby DP572 and DP571 audio processors are essential components for any cinema or professional audio setup. Their advanced features, compatibility with multiple audio formats, and the legendary sound quality synonymous with Dolby make them invaluable tools for creating immersive audio experiences that captivate audiences. Whether used in conjunction or independently, these processors deliver the high-fidelity sound that is key to modern entertainment.
