Option* for home theater and viewing room speaker/monitor synchronization setup with SyncheckII™. Now includes support for DTS, too.
* intended for Syncheck customers only, purchase with a new Syncheck2 or you will be asked to supply a Syncheck serial number
Recent display technologies introduce enough visual latency to "dance a jig on", and different technologies by different manufacturers introduce different amounts of latency. To compound the problem, not all DVD players manage to decode audio and video in synchronization! We were very distressed to discover this the last time we went monitor shopping. Armed with this DVD we found the same monitor measured differently from one store to the next. Why? Different DVD players were used in different stores. Sadly, perfect lip sync can only be obtained for a total system.
Our DVD is authored from our standard flash/pip reference files. One set of flash/pips uses our new "one-per-second" repetition rate. Another set keeps our "multi-spaced" pattern. For each set we have included several audio pip variations for various testing purposes. By changing audio "language" tracks, you can select between 3Khz, 1Khz, filtered pink noise, DC positive pulse, DC negative pulse. Don't worry, the pulses are very short, they sound like metronome clicks, and will not damage your system at any normal playback level. We include them for bench top testing purposes.
Reference playback level setup and two pink noise sections have been added for SyncheckII support. One pink section has full bandwidth (20 to 20k) pink noise, another has narrow bandwidth noise (300 to 3k). Both include LFE signals. Authored for -20dbfs reference level at unity gain playback (Dialnorm is authored at -31), a Hollywood standard. All of our pink noise files are authored and optimized specifically for measurement and playback with RTAs and C weighted SPL meters. See the SyncheckII user manual for more information.
Audio is now encoded as 5.1 channels for AC3 (Dolby Digital) and DTS on each disc. You must select a PAL or NTSC disc when ordering. Many machines, not all, will play either one but you should pick the standard that matches your video system.
