Diférence entre V1 et V2 ?

Citation :
Powerful New Functions for Applications from Production to Live Sound to Broadcast.

This significant upgrade places the DM1000 on the same performance level as DM2000V2 and 02R96V2. And like the DM2000V2 and 02R96V2, the DM1000V2 has now received THX® pm3™ certification. DM1000V2 offers an impressive range of additions and improvements including enhanced surround capabilities, DAW control for integrated production environments, refined automix performance, improved monitoring for broadcast applications, and virtual VCA functionality as well as AUX/SOLO link for live sound.

Citation : Seamless ADD-ON EFFECTS Support

The DM1000V2 provides full support for all five of Yamaha's ADD-ON EFFECTS packages (each package is sold separately). The advanced effects and signal-processing capabilities provided by these packages are accessed and operated via the console's internal effect processors in the same way as the built-in effects. You can also use the DM1000V2 Editor application for effect control.
ESAMII Video Editor Support

The main functionality of the 03D VEK video editing suite for the 03D digital mixing console is now included in the DM1000V2 system software. This provides support for major video editing devices that comply with the ESAMII protocol.
A Major Studio Manager Evolution

The Studio Manager application has undergone a major evolution, and is now a host application that can support multiple editors (such as the DM2000 Editor and SPX2000 Editor) within its framework. This offers many advantages including total project recall, and future support is planned for recall from Steinberg's Nuendo®/Cubase™ via the Studio Connections. Online and offline editing of multiple DM1000V2 or 01V96V2 units is now smoother than ever. A variety of other enhancements include Add-on Effect support, multiple windows, and improved overall operability through shortcuts, keyboard operations, drag and drop, and using the console's User Defined Keys to remotely open and close windows.
