Will Magma ExpressBox 3T add latency?

... additionally, any info if it would run Accel cards too?

Electronics 101 - If you put a signal on one end of a wire, it will not come out the other end of the wire at exactly the same time! There will be a delay!

Electronics 101.a - This delay is sometimes referred to as latency.

Now, to the question at hand...

Does the Magma ExpressBox 3T connect to your computer with a wire? Well, actually it's a cable, but yes, it does connect with a wire.

Will Magma ExpressBox 3T add latency? You should be able to figure that out for yourself from the information I've given.

Will this latency be audible? Absolutely!

Keep in mind that electricity travels at roughly the speed of light, or 186,000 miles per second, so...If your studio computer is located on Earth and the Magma ExpressBox 3T is located on Pluto, which is like a gazillion miles away, there would be audible latency.

How much latency would there be? It's Saturday morning...you do the freaking math! And by the way, you'd be wrong!

Given the volts and amps and distance involved, the poor little electrons would have fallen over gasping for air long before they got to Pluto, much less back from there, so you'd hear nothing!

(And yes, I know about induction, but most people who have such a poor excuse for a life that they've bothered to read this far probably don't, so let's not confuse the issue. Capice?)

Now (slap!), a dose of reality. Would the "wire latency" involved with the Magma ExpressBox 3T be noticeable under real-world conditions? Probably not.

Now aren't you glad you asked (and read this far)...

Ha ha very funny.

From the past I know some Magma chassis'es have introduced additional latency when used with Pro Tools HD systems and then again some other Magma items have not.

Out of everyone who's used any brand of Thunderbolt to PCIe chassis, I've not heard anybody mention any latency problem. They seem to be working great for everyone.

Thunderbolt uses the PCIe protocol, so the computer sees it no differently than it would an internal PCIe card.


As to the other question, HD TDM cards are not compatible, and I doubt they ever will be, as Avid has no incentive to bring compatibility to a discontinued system.

Thanks. I don't quite understand what you mean by Accel cards not being compatible. I can understand they will not be officially supported, but compatibility should be no problem since they are PCIe cards like any other. Would just like to know if someone has actually tried it or not, but I guess I should be asking in TDM forum instead.

It's not that simple. With Thunderbolt, the company that makes the PCIe cards has to specifically make a driver for the cards to be recognized. Avid has done so for HDX and HD Native, but I don't think they plan to for any of the other cards.

My POV for answer #2.
I think Mr. Denton should do the math just to follow through with the Electronics 101/101a...

I'd rather think of content relevance.
