There are many models in the LasrPlay and DVDplay series, but it is easy to remember the different model names. Just add the number of channels after the name. This means, for example, that the DVDplay-2 is a 2 channel DVD synchronizer while the LasrPlay-2 is the same thing for laserdisc players. There is no limit to the number of channels that can be built into a LasrPlay or DVDplay unit because every channel has it's own computer, so a DVDplay-25 would have 25 channels. In addition to the number, there may be letters at the end of the model number to define options that were ordered. See the tables at the end of this booklet for exact model numbers.
There are a couple of optional features that can be built into a synchronizer. Most installations do not require these options. As mentioned earlier, the DVDplays can be made with an optional Black Burst output and the LasrPlays can be made with a similar option which puts out composite sync. These options allow more accurate synchronization as well as locking the images to the vertical interval, which is useful when the images are going into a video switcher. Any standard sync generator that puts out these signals will work, but it is often easier (and cheaper) to have this built into the same box as the DVDplay.
The synchronizers can also be made with an option known as a "network connector" which is used to tie together two or more synchronizers to make them act like one large synchronizer. Even though this is called a "network" connector, it is not a computer network. It is an extension of the proprietary internal network that channels use to synchronize with each other. It can also be used to keep the channels from starting a playback loop. By connecting this to a switch or contact closure that shorts the pins together, you tell the synchronizer to not start. Once the switch is pushed or contacts opened, playback starts.
The DVDplay is compatible only with Pioneer industrial DVD players and the LasrPlay is compatible only with Pioneer industrial laserdisc players. The DVDplay supports Pioneer's DVD-V7200, 7300, and 7400. There are a number of current and older industrial laserdisc players that will work with the LasrPlay. These include all models in the 2000, 4000, 5000, and 8000 series, except the 2000E which does not have a serial port.
The DVDplay is designed to work with DVD-Video discs, whether they are mass produced or DVD-R custom recordings. It is not designed to work with Video-CD, which the industrial players will also play. Video-CD is an old non-DVD format used primarily in Japan with MPEG-1. DVD-Video is the DVD format that uses MPEG-2.
The LasrPlay is designed to work with CAV type laserdiscs, though a CLV version is available by special order. The CAV discs can hold up to 30 minutes of NTSC or 36 minutes of PAL video. CLV can hold a longer period of time, but CLV discs can not be synchronized accurately. They are OK if you don't mind the channels being off by as much as a second from each other.
The LasrPlay and DVDplay run off of 100-125 or 220-240 volts (which is switchable on the back with a small screwdriver). All of our synchronizers are supplied with a detachable American standard power cable for 110 volt use. They use the standard international IEC power connector on the back of each unit, so a local power cable can be purchased in almost any country in the world. These are the same power cables used by computers, printers, and many other electronic devices.
