1.5Quickstart Guide for the DP571 and DP572

This section supplies necessary information to allow immediate encoding and decoding.

1.After unpacking the DP571 and/or the DP572 but before applying AC power, plug in a stable analog video reference signal. Standard black burst or color bars can be used as reference video if they are locked to the plant reference.

Since neither unit will function without a video reference signal, we recommend making this connection first.

2.Connect the digital audio inputs to the DP571.

These are AES3-ID inputs (unbalanced, 75Ω, 1 V peak-to-peak standard output), and are very similar to analog composite video.1 If the loop-through BNC connectors are not being used to feed additional equipment, terminate them with a standard 75Ω video terminator.

3.Connect the digital audio outputs of the DP572.

These AES3-ID outputs are electrically separate, not loop-throughs, and should not be terminated at the DP572. Like analog composite video, the termination should be placed on the last device in the signal chain. For example, if the DP572 is connected to a DP569, the terminators should be applied to the loop-through BNC connectors on the DP569.

4.Connect the Main Out of the encoder to the Main In of the decoder and terminate the input.

5.Apply power to the DP571 and/or DP572.

6.After completing the boot process (about 25 s), both units show their current status on the display (same configuration as when they were last powered down).

7.If the VRef LEDs are not green on both units, make sure a valid analog NTSC or PAL reference signal (black burst) is applied to both units and that they are properly terminated.

8.The DP571 shows the current encoding Program Config. Set it to 5.1 + 2 by

pressing Setup + Enter when the display shows DP571 Unit Setup: Program Config. The display now shows the current program configuration. Press the ↓ or ↑ keys until 5.1 + 2 is displayed and press Enter. The square cursor to the left stops blinking and disappears to indicate the value has been entered.

1.Using video equipment for distribution of this AES signal is not generally recom- mended. Equipment is available designed specifically for passing AES3-ID signals.

DP571, DP572 specifications

Dolby Laboratories has long been a pioneer in audio and video technology, continuously pushing the boundaries of entertainment experiences. Among their range of innovative products, the Dolby DP572 and DP571 audio processors stand out as powerful tools for commercial cinema and installation applications. 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.
