|description=The '''Leitch DPS-575''' is a broadcast-quality digital processing synchronizer designed for use in analog, digital, or hybrid production facilities. Originally developed by [[Digital Processing Systems]] (DPS) and continued under the Leitch brand following the 2000 acquisition, the DPS-575 combines frame synchronization, time base correction, format transcoding, and audio/video processing in a single 1U rackmount chassis.

== Relationship to DPS-475 ==
The DPS-575 is '''hardware identical''' to the [[Leitch DPS-475|DPS-475]]. The only difference is that the DPS-475 has a software lock restricting it to NTSC-only operation, whereas the DPS-575 supports auto-sensing dual-standard PAL/NTSC operation.
According to discussions in the laserdisc community, it is reportedly possible to convert a DPS-475 to a DPS-575 via firmware flashing, effectively unlocking PAL support. See [https://forum.lddb.com/viewtopic.php?t=4502&p=72668 this LDDB forum thread] for details.
== Videos ==
There's a nice video entitled "Working with the DPS-575 and creating Audio Terminal Block connectors" available on YouTube about the DPS-575:
{{#ev:youtube|j1uzNuFdN08}}
The video is presented by Morgan Morel of the [https://bavc.org/ Bay Area Video Coalition (BAVC)]. It goes over some features of the DPS-575, known quirks, and how to connect XLR and RCA cables to its audio block connector.
