I never got a good chance to ask this week, but the 5D has the same problems right? I couldn't find a way to map the pan to the encoder in the case of stereo mixes. Also, Ramtech makes a solution for the 1D as well. It has a rack mount box with either 1 or 2 SCSI connectors and 4 or 8 BNC lines and the rest of a 54 pair mult filled with up to 10 XLR tie lines. It's kinda hard to tell from their page, but I think it uses a custom cable in the mult so not just any 54 pair will work.

That fits real well with the Ethercon and Powercon. I'll have to check the price. It will be interesting to see if someone can come up with a four core that doesn't cost an arm and a leg as well. Mark good to see you posting here. Regarding the fiber my point is that the guys showing the gear as well as the guys working with the rigs need to know the differences between the two. These guys didn't seem to be familiar with fiber though in fairness it really wasn't thier gig. I had to download the docs for the Artist 1D to see what it was about. Good point about single mode being pretty much a telco/datacom thing. The cable cost isn't that different depending on what you're buying (likely that multi mode cable is a bit more expensive) but the transciever cost difference is pretty significant. I always ask if they don't say and even then for most of the portable apps it's provided as turnkey product where you can plug and play and don't have to source parts separately. I haven't looked in a while but 10Gb ethernet switches even using multimode interfaces the cost is pretty staggering. At that point the cost difference of a 10GBase-LR (10 km single mode) and 10GBase-LX4 (300m multi mode) interface cards in the big picture won't be as big a deal as the cost of the unit as a whole. Gigabit ethernet will surpass 100Mb just as 100Mb surpassed 10Mb and it won't be too long before 10Gb is more affordable. In the next year or so it's likely we could see 10Gb on copper.

Re: "When I asked if it was single or multimode fiber a similar confusion ensued, with one person saying yes you could operate the snake both ways." This confuses me a bit as well... As I understand it, single mode fiber is something that we plain don't see in our industry at all until you get into telecommunications, due to the astronomical cost of the gear needed, and the fact that mutimode is still good for 10 Gbit/s for distances up to 300 meters... is that not true? I don't think I'd believe the guy about the Yamaha snake, or am I missing something? Hey Dave…

He said you could use either control on the slave console, but they both controlled the attenuator, not the pre. I don't think it's a big deal either way, you should be leaving plenty of headroom for the ADC anyway. One thing the Yamaha guys made clear was to be sure you are close in level before you enter the tracking mode, so you don't run out of attenuator range when you readjust the mic pre. You only have 24dB available on the gain side of the attenuator.

On the PM1DV2 you have to assign which surface has control of the preamp and my understanding from Jose (I made it a point to ask more about it) is that only the assigned V2 surface has control. They are similar in that the digital attenuator is used as the tracking compensation but with the D5 either surface can control the pre amp. EDIT: After thinking about it for a couple of minutes (and refering to the manual) if you are using MADI over coax on a D5 only one surface has control though the changes are tracked. The fiber rig needs to be used for bi directional tracking. Never realized that before though I've only gigged with either the fiber or a copper split with that surface.
