Presonus Studio 192 Mobile audio interface

Postby w-u-2-o » Sat Jan 13, 2018 5:09 pm

For a long time now I've been using the Behringer UMC202 professional audio interface. I am fully virtualized and run all of my audio, receive and transmit, through the PC with it. No connections to the radio other than Ethernet. The Behringer is an unbeatable value at only $60 when compared to its competition from Steinberg and Focusrite, not to mention having much better and more stable drivers, too.

However, I've been craving lower latency. In order to achieve that, one must move up into the world of USB 3.0 interfaces (expensive), Firewire/Thunderbolt interfaces (very expensive), or professional audio PCIE cards (stupid expensive). Right now the USB 3.0 market is very small, and consists primarily of the Zoom UAC-2 for $300, and the Presonus Studio 192 Mobile at $500.

Recently the Presonus unit became available on eBay for less than $400. I picked one up for $380. Used ones are occasionally available for around $300.

Image

After swapping out the venerable Behringer with the Presonus, all I can say is "WOW!" Zero, and I mean ZERO latency (<3mS) monitoring. That's even with the audio travelling first through Voicemeeter Banana, through the Reaper digital audio workstation (DAW) software, and back through Voicemeeter Banana (VMB). What a difference from the Behringer UMC202!

PowerSDR remains the usual stumbling block, as MON has many tens of milliseconds latency on it. But outside of PowerSDR latency is zero.

Leaving aside PowerSDR, the DAW is actually now the limiting factor. I need to find a better DAW! Windows and VMB will happily run at a Presonus buffer size of 32 (the minimum) at 96KHz. That's only 330 microseconds of buffer. Adding in the DAW I have to run at a buffer size of 128 at 96KHz. Of course that is only 1.33mS, but with the right DAW I should be able to get into the sub-millisecond range. BTW, same performance at 48KHz, just drop the buffers one increment and get the equivalent latencies.

Pro's: fantastic audio quality, really nice headphone amp (I need to get better headphones now!), effectively zero latency (outside of PowerSDR), highly flexible controls. It even has an external clock reference input!

Con's: highly flexible controls (it took me a couple of hours to unravel the mixer app that is part of the control panel), and cost. At the $380 I paid it's far cry from the Behringer at $60. Unfortunately it's a big cost leap to get into the zero latency interface regime.

As I mentioned, the controls are highly flexible, as it is designed for professional studio use. This may be too much complexity for some. Here's a shot of the Presonus control panel next to my normal DAW mixing board.

Image

It all fits quite neatly underneath and between two of my monitors. I think I may move it over to the right side though.

Congratulations on your new sound card and especially to ZERO delay!!
Always good to hear about others sucsess I have to say :D
I'm running with a sound card called M-Audio M-Track 2X2X4 which also has USB C, but I do not really know. It's then delayed, even if I listen to another recipient when I send .... I've changed computer when my sons gaming computer crashed and he had to take my newly built, so maybe the delay is because of that even though this is not so bad Have not run any tests on it yet.

I have mostly been to VHF since we have / had huge conditions there and most likely because of the cold. Around -25 celsius for a week :roll:

Scott this may be a dumb question but do you have to turn the mic level off when you are Txing in digital modes or is there some other way to handle this ?

Not a dumb question at all, Tony! The answer is that you do indeed have to turn off the microphone somehow. There are many options here.

1. Disconnect the microphone ;)
2. Turn down the microphone gain.
3. Use the mixer app in the Presonus control panel to turn off the microphone.
4. Use a completely different set of devices (virtual audio connections) when using the microphone vs. when using digi mode app's.
5. Use an external mixer app, such as Voicemeeter Banana (VMB), to control audio routing to/from PowerSDR and third party app's, including DAW software.
6. Do all the final mixing and routing in a DAW app. using VMB as a patch panel (this is how I do it).

I strongly recommend using method 5 to start out with. There is a little bit of learning curve, but once you get it figured out you will find it simple, easy, and wonder how you ever did without VMB.

Much of what you need to know is in my VAC tutorial, but I feel a video tutorial coming on soon :)

Are you thinking of buying a Presonus? If you do, we'll probably be expanding this thread a little, because the setup of the mixer app in the Presonus control panel is another interesting layer of complexity, as I noted in an earlier post.

It's a hell of a piece of kit, though! I recently found it has the power to drive some professional, 80 Ohm, studio headphones, too!

Thanks Scott, yes I'm strongly tempted to get the pre sonus . My current set up is fine but I think this would take it to the next level. I've been using VMB for a while so guess it will be as easy as a button push when changing from SSB to digital modes . The pre sonus is quite a bit more expensive here in EU so may have to wait until I visit WY in July to get one.

Minor update: I found a DAW that will run at the minimum buffer size of 32 at 96Khz, Reaper. But... As soon as I added a single VST plug-in I had to increase the buffer back up to 128. At least I know for sure where the weak link is, now.

Yes this looks like the interface for me as well ultimately. You'll never be getting any photos of my shack it's far too messy. So it's official Scott, you are the VAC audio guru. I had not seen that you were using Reaper but independently decided it was the way to go. I could have saved a few hours if I had seen this thread first.

I know that this Presonus 192 Mobile is very good soundcard and popular with musicians on the go!
What I wonder is if you do Scott with the other ports available on this sound card?
I'm looking around for what's replacing my M-Audio M2X2M and I think that after a certain money limit, it's the number of inputs and outputs that distinguishes them (in addition to the preamp quality and the software that comes with) and wondering why do something special with the ports you have over, or if you're strictly using it for the amateur radio?
I know there is a lot of difference between the software between them, but still as well.
I'm stuck to Universal Audio from what I read, but would be nice to hear why you just fell for this sound card.
Everyone I'm looking at is 24bits / 192kHz which what I have now is also.

Thank you very much for enjoying my shack!
I'm a bit picky when it comes to cables that hang and throw and have rebuilt it after that picture.
I rarely have the same setup for more than a month at a time ....
Our hobby has many branches if I say so :P

Thanks in advance, and a nice weekend to all!

I can also take care to tell you that today I got my new Wavenode probe with RF View so I can measure my Acom 1500.
Just in this moment, it is about solving cable between the probe and the radio.
Tells later how it works.

What I wonder is mainly the difference between sound cards for 200, 600, 1000 EUR for even more and, above all, how we defend this to the hobby we have.
Believe that more than I think of this :)

Tommy--I only use two inputs and the main and headphone outputs. Input 1 is for the Behringer B1, Input 2 is for the AKG WMS420 wireless with the C555 mic.

I use this strictly for amateur radio.

Everyone I'm looking at is 24bits / 192kHz which what I have now is also.
The way I look at things, sound interfaces breakdown as follows:

- Non-ASIO sound interfaces--not worth anyone's time
- USB 2 based sound interfaces--only the Berhinger works well, everything else is in second place because the Behringer has the best drivers, and the mic pre-amp's are darn good, too.
- USB 3 based sound interfaces--this is where you can start to obtain zero latency (outside of PowerSDR). The Zoom UAC-2 is the least expensive choice, the Presonus the second least expensive. I found a Presonus on sale on eBay and grabbed it.
- PCIE interfaces--super expensive, way too much for me!

I interpret that "these" sound cards are over-priced for us radio amateurs.
What I want is software so you can influence what you want now via the computer and not just a hardware on its card.
As I said, I have stuck to Universal Audio's products, but do you think anything works to what we are doing?
I'm now looking the most on the UA Apollo Twin MKII solo or maybe even more on the Audient iD44 (which is very recognized) released today, and maybe later because they are world-renowned for their quality not the most of their micpreams.
What disturbs me then is that the Audience "only" has 96kHz against most other new sound cards including my own has 192kHz what it's doing now.
I do not need mass inputs and outputs, but would like to have two monitor outputs because I hate two sets that would be nice to switch between.
Feeling a bit "lost" in this jungle, but it's normal that the more you read about things, the more dull you get

There is no reason to run 192KHz unless it is to achieve lower latency, i.e. you have bottomed out your buffer sizes and wish to obtain a smaller delay through that buffer by increasing the sample rate. The reason that this is true is because all audio entering the radio is either sampled or re-sampled to 48KHz, and all audio processing inside the radio is accomplished at 48KHz. Personally, I'm running 96KHz because I was able to bottom all of my buffer sizes at 48KHz.

The UA and Audient products are relatively high end choices that are, as you say, probably overkill for amateur radio. The absolute best value is the Behringer UMC202HD at less than $70 USD. Next up from that would be the Zoom UAC-2 at $300, and then the Presonus at $400, although I've seen them used for near $300. Unfortunately there are no low priced USB 3 or USC C interfaces yet. All we really care about for ham radio is speed, and we have to accept expensive feature sets to get that speed. But the UMC202HD is fast enough for all but the most discriminating ham ;)

Looking at price point again, using the very popular W2IHY external amateur radio audio processors as a benchmark, anything under $400 is not totally unrealistic. However, I find the W2IHY gear to not be a good value. For example, one can obtain something like a DBX286s mic preamp/processor and combine it with a DBX166 compressor/limiter/gate and any number of DBX EQs and have ten times the capability of a W2IHY setup for less money. Once could even feed that into a UMC202HD and straight into the computer. Or, alternately, get some inexpensive (darn near free) DAW software like Reaper and do a lot more for near nothing and no external gear except the interface.

IMHO, the only external processing needed right now with PowerSDR is a gate. The gate in PowerSDR is far too simplistic and does not provide for good VOX operation.

I have to say I'm getting more impressed with this Presonus Studio 192 Mobile sound card the more I read about it and the more Youtube videos I see!
Their UC Surface and Fat Channel plug-in processing on every analog input seems to be cruel!
All I do not like is the form factor on it which is not easy to influence :roll:

How do you think, for example, that the gate that is built into the software works and the other adjustments you can make there, is it something you use or are you running other plug ins?

As usual, we have a strange pricing image here in Sweden, and this card is quite similar to the UA Apollo Twin MKII and Audient ID44, so thats why I go back and forth which one suits me best.
Seems to be the software that is the biggest difference between them and there it would be best to test them live so to speak, but the Presonus seems to be absolutly amazing!

I know all about W2IHY when I had ( and still have the 8 band eq & EQplus somewhere) all of their products many years ago when I started with ESSB and then it became a lot of rack stuff after that.
Right now I have a DBX 286S that you mention before the sound card for not having to max the micgain in the card to my PR40 instead of a Fethead or Cloudlifter and for a better noicegate.

I don't care for the Fat Channel processing. I now use all of the built in features of PowerSDR mRX exclusively except for the gate, which is way too basic and non-adjustable. Since I use the Reaper DAW as a virtual mixing board on the station, I use a gate plug-in in Reaper that I like.

Just a brief note on this thread that is a bit dated.

Presently I am using a Steinberg UR22 and it has worked well except that has a USB2.0 connection only. However, I also found, just now a Steinberg UR22C 2-Channel USB3.0 Type C Audio Interface which sells for $189.99 right now so I may be getting one. My garden variety lap-top features 2 USB3.0 ports and one USB2.0.

Best!

Is the 192 Mobile discontinued? All the usual places (Guitar Center, Musicians Friend, Sweetwater, BH Photo) all show the 192 out of stock or unavailable.

Hope it's not true! The 192 offers an inexpensive way, via its WordClock interface, to sync ASIO audio with OpenHPSDR derived radios.

I see eBay and Amazon still have a few for sale.

Wow, it looks like Presonus has completely revamped their line up! :o And it's all bait and switch. NONE of their new "USB-C" interfaces actually run at USB-C speeds; they are all still USB2.0! That really sucks! :evil:

So yes, grab those Studio 192 Mobiles from wherever you can. The closest thing you can find in the Presonus line-up now is the Quantum 2, at $600USD list price. It has the world clock IO, and a legit Thunderbolt interface (and you'll probably have to pay for a Thunderbolt PCIE card, too).

The Steinberg UR22c looks really great! A true USB-C interface, and not very expensive. I've never been a fan of the Steinberg drivers but maybe those have improved as well. If someone gets one I'd be very interested in hearing about it.

I see PreSonus 192 Mobile still being sold at the usual on-line stores......

Will likely spring for the new Steinberg, but it likely doesn't make much sense unless I first upgrade my lap-top as it does cause audio drop-outs and other glitches based on latency tests. One of the largest "contributors" being an "ACPI Driver."

Should I get a better PC (with SSD) I will most likely get the Steinberg for a look-see.
