I like to give our products short names that are easy to remember and to type.  USPCB seems easy.  It is a concatenation of USB and PCB (meaning Printed Circuit Board).  Rolls off the tongue well I think.

 

...not to forget USP

One task of my daily routine: refresh Uptone's website page from time to time to check whether ISO REGEN pre-order page is online.

Great question that a lot of people would be asking (looking for best bang for buck). But it seems like the ISO REGEN needs either an LPS-1 or a linear power supply (for the leakage currents reasons). Certainly the upgrades can be done in steps though but the ultimate end result is LPS-1 and ISO Regen for sure. Just depends how quickly each person decides to get there, depending on each budget at the time.

 

If I were you (given your current setup) I'd actually start with the LPS-1, replacing the SMPS and when funds allow later add an ISO Regen. Only one opinion though. Certainly no hard and fast rules with this game :-)

Sound advice my friend! 

 

Order placed for an LPS-1

Just to let everyone know, the area where Alex lives was hit by a big storm a couple days ago which knocked out the major communications hub in the area. As of last night he had phone service restored but not internet.

 

He has not been ignoring people, he just could not get on the internet. It still be some time before he can get back online to answer questions.

hope communications are all that was affected

But if your DAC needs VBUS power, then you have to feed our REGENs (both models) at least 6V since the regulator for VBUS needs to be able to drop some to regulate to 5V.

 

Perhaps a dumb question...I am using an SU-1 that I want to power with 5v from the LPS-1.  Ideally I could use the LPS-1 to also power the Iso Regen at 5v.  However, the SU-1 needs vbus power as well.  If I use the LPS-1 to provide the vbus power via my split usb cable, can I then power the Iso Regen (and SU-1) with 5v instead of 6v?

Could you please give a little more detail on the system you are trying to put together? I assume you have some sort of source that outputs USB, then you want to go through an ISO REGEN, then to an SU-1?

 

I'm not familiar with the details of the SU-1, you mention it needs VBUS but also needs external power, correct? If so it sounds like you will be having double isolation, which will be bypassed if you feed both from the same LPS-1.

 

If the VBUS from the ISO REGEN is driving ANYTHING, then the voltage powering it must be higher than 5V. If you use a power injector to feed the load then you could theoretically get away with the same 5V driving the ISO REGEN and the injector.

Thank you John.  Right now, my system is PC >> SU-1 >> DAC.  I want my system to be PC >> ISO Regen >> SU-1 >> DAC

 

The SU-1 needs VBUS as well as external 5v.  Right now I am powering both the SU-1  and providing VBUS to it from a 5v battery.

 

I understand that if the ISO Regen is driving the SU-1 it will need higher than 5v which is why I was thinking if I use the LPS-1 to provide the VBUS then I could use it to also power the ISO Regen and SU-1 at 5v instead of 6v.  

I hope that makes sense.

I wanted to power the SU-1 and ISO Regen using a single LPS-1 as well. But, the SU-1, according to Singxer, must receive 5vdc only. Any more and it would be damaged. The SU-1 uses the USB VBUS power so the ISO Regen would need more than 5vdc.

 

So, a single LPS-1 is not going to work. I am not inclined to buy a second LPS-1. So, I am inclined to use a Mean Well SMPS to power the ISO Regen and a Mean Well SMPS to power the LPS-1 powering the SU-1.

 

I decided to hold off buying the SU-1 and to continue to use the Singxer F-1 I have instead. I will use the LPS-1 I have to power the ISO Regen when I get it.

Exactly.  Which is why I am asking if I can supply VBUS from the LPS-1 via a split USB cable.  This would bypass the ISO Regen supplying the VBUS.  I would use 3 way splitter from the LPS-1 and power the SU-1, ISO Regen, and VBUS all at 5V.

 

Sounds like from John's response this would work in theory.

So why not just set LPS-1 to 7 VDC, and insert a resistor that drop the voltage to 5 on the SU-1. You are in any case modifying your SU-1, right ?

(You bypass the original SU-1 PS and use the LPS-1, or have I misunderstood how the SU-1 works)

 

You want the resistance as high as possible. I'm sure John can confirm this and suggest a value.

 

I suppose you already has verified powver consumption? (Thought I'm not sure if the ISO regen numbers has been released.)

Using a resistor to drop voltage from 7V to 5V is not recommended.  The voltage will change depending on device current draw (per Ohm's law).  Even using 3 diodes in series to realize a ~2V drop will not be all that good.

 

There should be no need to mess with 7V.  Set the LPS-1 to 5V to power the ISO REGEN, do VBus injection via USB cable into the SU-1 (to power the XMOS receiver module on upstream side of the moat) and finally the SU-1 downstream logic via a modification to bypass the internal linear PSU and run in 5V via a DC jack.  If you want to do this then you need a 3-way DC splitter cable with three 5.5/2.1 DC plugs wired in parallel.  Like John said, this scheme will bypass much of the isolation that ISO REGEN and SU-1 offer with their designs.

 

A more sensible power solution would involve at least two supplies, one for ISO REGEN, another for SU-1 (2 rails).  Perhaps a battery can be used to power the ISO REGEN.  The ultimate configuration would involve three LPS-1 supplies, one for each rail, to take full advantage of the double isolation.

Still haven't heard anything from Alex.  I hope that everything is OK with you.

Yes, everything is fine thanks.  Just finishing up a lot of details for the launch. Some parts are in short stock at the regular distributors and take time to track down.

Almost done with final costing, and once boards are on order with a quoted delivery date I can turn my attention back to the rollout.  

At that point I'll start a new thread, post product details and photos, and announce pricing, bundles, and a ship date.  I feel it best to put that all together to have a coherent and successful launch of the ISO REGEN.

 

Right now I am feeding the ISO REGEN into a Singxer SU-1 USB>I2S box witch in turn feeds a Holo Spring Level 3 DAC.  Using HQ Player to play at DSD256 I am getting the best sound I've ever had in my room.

 

Honestly, the galvanic isolation of the ISO REGEN is just icing on the cake.  It is all the other massive (and expensive) enhancements we have made to the device (over the original REGEN) that make this new piece perform wonders.  John and I can't wait for you all to hear it!

Sent the final board files off today!  Making last minute case milling revisions this weekend.  Expecting to announce all pricing for bundles and rebates next week.  If both our board house and chassis vendor give us dates right away, then I may even be able to announce delivery date.

 

And oh, this thing sounds heavenly!  I know we are racing against a worthy competitor who has expertise and lots of marketing, but ISO REGEN will be ready to take on all challengers.  I know we are spending way more on the best parts and a world-class clock.

 

 

Tomorrow I'll send off the files for the USPCB (male A > male B) adapter and we'll see where the cost lands for that little cutie.  I am hoping assembly will be cheap as we really don't want to charge a lot for the item.  But it is VERY effective and much better than the typical short USB cable or solid adaptor.

 

Have a great weekend everyone!

P.S.  John and his wife are driving up to Tacoma this weekend to move into an apartment while looking for their new dream home (with space for a great engineering lab of course!).

I'd be lying if I was to say I wasn't excited to hear more.

I promise you will.  Very soon.  I'll start a new thread and post pics and details.  Will announce the new thread in this one so that subscribers don't miss it.

Absolutely!  Everyone who has ever bought an UpTone product directly from us--and anyone who put their e-mail address in the "Newsletter" signup box in the lower-right of our homepage--will receive a notice at least the night before the AddToCart goes live on the (yet-to-be-created) ISO REGEN product/order page.
