1.7Configuring Jumper Settings

Although the DP571 encoder and DP572 decoder will function correctly with no internal adjustments, five jumpers provide additional termination options. Any necessary changes to the jumpers should be made before the units are installed.

There are 124 Ω terminations on both units for the RS-485 Metadata and Remote control ports. The units ship with these terminations bypassed (pins 3 and 4). Refer to the table below for additional settings.

The only remaining terminations are accessed via the passive loop-through BNC connectors on each unit’s rear panel. The video reference input on both units should be terminated if the loop through is not used to feed other equipment.

The AES3-ID-1995/SMPTE276-M standard uses a 75 Ω connection and requires proper termination. As with video, the termination should occur only at the destination of the signal (i.e., on the inputs to a device). For the DP571, the loop-through BNC connectors for the inputs must have terminators if they are not being used to feed other equipment. For the DP572, the loop-through BNC for the Dolby E input must be terminated.

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.
