Halide Design Bridge - Async USB converter - Page 3

Might have to look into that some more. I would definitely like to know if daisy chaining transports would be beneficial. That would be quite interesting to find out!

I've got a USB isolator coming for the Bravo, not sure if I will really need it on a Mac, but I boot into Windows also:

Also it may not be necessary for the Bridge either from what I understand.

Where did you buy that USB isolator, grokit?

That's interesting.

I think I'll give it a try

leeperry mentioned that the Halide and the isolator might not be compatible with each other due to "galvanic isolation"; it's a little beyond me, but he is the one that led me to the isolator, so here is his post regarding that.

I will try it based upon his feedback with the Bravo, but I still wonder about the Bravo/Halide combo, essentially upgrading the isolator to the Halide to use with the Bravo's coax input. But that might not be compatible either, more research is needed!

For the USB isolation talk.

When I used the Musiland I would get a noticable sound, like a 60hz drone, whenever I put my hands on the laptop to type. I never checked to see if it went away when the laptop was disconnected from the wall power like it always did with the 0404usb. Just unplug the laptop before listening and all was good.

I have no such issues with the Bridge. No noise or problems of any kind. No matter if using battery power or wall charging. 

My HP laptop has a noisy usb, but has built-in optical thankfully. The Halide eliminates noise by going to S/PDIF as well, but it also provides superior timing due to it's (regenerated) usb-powered asynchronus transmission, I believe. Would that be compatible with an independently powered re-clocking device as the next part of the digital signal chain, like the Bravo?

At least one inquiring mind would like to know

Not really, the real prerequisite is speed(480Mbps USB2 can't work), most 24/96 transports will work but not 24/192...the Hiface is no workee: https://electronics-shop.dk/?id=900

So no workee because the Halide, like the Hiface requires 480Mbit HighSpeed USB2 all the time?

Well, apparently the Musiland do work fine in 24/96...I guess it all depends, and there's only one way to find out.

I should have checked this thread before i bought myself this.http://www.hvwtech.com/products_view.asp?ProductID=1226&utm_source=Google&utm_medium=Product+Search&utm_campaign=Product+Search+%28Jul10%29 But it was the same price after shipping so no worries .

It has "full/low speed USB 2.0 compatibility", so it may work with a wider variety of devices. Does it need a separate power source?

Yeah, it requires a separate power source, won't use any bus power, "Device requires 6to25VDC 500mA 2.1mm barrel jack power supply. "  Ill have some wallwart power it from my furman. I guess you could power it with batteries, i cant picture the halide consuming that much power it might be worth looking into. Talk about isolation!

grokit: it's the same adum4160 chip that support low and full speed like the dongle you got, the fastest speed of USB 2.0 is called Hi-Speed and it is 480Mbps. (Well you have another mode called SuperSpeed for USB3)

more impressions please.
