DL2 vs. DL1

Okay, so I have a serious question to ask and I'm looking for straight answers and explanation.

I was told by someone at High End that the DL1 is not built to the same tolerance as a DL2.

There was no elaboration on this but I want to know...

Let's pretend I am not using the Media Server built into the DL2 but plugging in an RGBHV cable to the light. I want to know exactly where the DL2 is different from the DL1.


I am asking this question for several very important reasons. In the next year, I will be responsible for making the decision to install as many as 20 media server and moving yoke projector packages. Considering that's almost a half million dollars, I want to know what my choice gets me.

Here is my argument. I have promised the owners of the venues where I am doing these install designs that when the installation is finished, they will be able to have their programmer sit down and program looks on the media server without having to strike the projector lamp in the fixture to see a preview.

What this means is an LCD screen connected to the media server that would sit in front of the operator during the time the projectors are off.

Now my preference is to Have Axons installed in a rack and DL1's in the air. I would run a cable from the camera to the rack and another cable from the axon to the light. Of course I would split the signal from the Axon to feed to the preview monitor. (On and technically I will be using sVideo-over-Ethernet for the camera and RGBHV-over-Ethernet for the Signal to the PJ but whatever.)

Right now, if I use a DL2, it means I have to run two sVideo lines to each light for the camera out and capture in, but it also means I'd have to violate my High End DL2 warranty when I open the case and put a distribution amp inside, and cut an opening to run an RGBHV back to a preview monitor.

Yes, I love the LCD on the front of the DL2 but no, it's not useful for this specific application.

Besides, I would rather have the Axons on UPSs so I can protect them better. The projectors I would just have on surge protectors.

    Todd,

    I'm not exactly sure what "tolerances" you are looking for an explanation about, so I'll hit all the similarities and differences.

    Physically, there is only one main difference between the DL.2 and DL.1 (other than the obvious top box) and that is the pan bearing. The DL.2 has a much more robust pan bearing on it allowing for side hung applications (although we don't recommend this because it causes issues with lamp life and cooling correctly). If your DL.1s are going to be hung box up or sitting box down, this is a moot point.

    Operationally the big difference is the encoders. The DL.1s use analog style encoders while the DL.2s use much higher resolution digital encoders. The exact resolution numbers escape me at the moment, but 1000 times higher for the DL.2 is a completely reasonable guess.

    This is not to say that the movement accuracy and repeatability on the DL.1s is bad, only that the DL.2s are better.

    Other than that, everything is the same. They both have the same projector, same cooling/filtration system, same yoke, bezels, etc.
