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.

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.

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

73!

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:

Here is a new picture from the SA3ATF studio and the soundcard is in the front of the right speaker.

Behind the computer, it's a 1,5kw Dummy load if you're wondering what's in the bag. They are not tight as you may know ....

Congrats Scott, great looking unit. I'm very tempted :-)
