UAD: The Industry’s Most Respected Collection of Audio Plug-Ins

UAD: The Industry’s Most Respected Collection of Audio Plug-Ins

From serious home recordists to multi-platinum mix engineers, UAD Powered Plug-Ins have been winning over audio professionals for more than 10 years. The reason is simple. No other plug-ins so faithfully capture the sound and behavior of classic analog equipment — from rare compressors and equalizers, to vintage reverb processors and tape machines.

The UAD library features over 90 plug-ins, co-developed with the biggest brands in audio. These plug-ins can be purchased with UAD-2 hardware from retailers as part of bundled packages, or you can buy UAD plug-ins à la carte from UA’s Online Store.

Available with QUAD and OCTO Core Power

Available with QUAD and OCTO Core Power

UAD-2 DSP Accelerator cards are available in QUAD and OCTO configurations, with four or eight individual SHARC processors respectively. The four-processor UAD-2 QUAD is a workhorse of modern mixing, giving project studios the power to run medium-sized sessions. The eight-chip UAD-2 OCTO is perfect for UAD power users, allowing professionals to craft mixes filled with the rich analog sound of UAD plug-ins. Up to six UAD-2 devices can be combined in a single system.

In developing UAD plug-ins, UA’s engineering group undertakes a thorough physical modeling of classic audio hardware — “rebuilding” vintage analog gear in the digital world, component by component. That’s how UAD plug-ins replicate the exact, sometimes quirky, behavior of analog hardware — bringing its rich, three-dimensional sound and harmonics "in the box."

UAD-2 PCIe Cards

UAD-2 PCIe Octo

I recently bought a second UAD2-Quad Sat (FireWire 800 on PC) and it was great to enjoy doubled plug-ins capacity. BUT for some reason my system has been crashing (once), each time I rename my Cubase files (weird). Then I just bought a PCIe OCTO (-50% from Thomann) and no more issues… It works perfectly !!

Octo Cards are simply the best

After many problems with all other UAD hardware solutions, eg. thunderbolt, Firewire, PCI-E Quad, are the Octo PCI-E simply the best available solution.

Think twice before comitting...

UA told me the Quad is not a current product anymore and wont help with any support even though it's still mentioned on their UAD page on their site. (this was 4 months ago.)
Beware if you think of buying a Quad system.
Otherwise a great environment and good plugins, but with everything now going native and sold cheap I wonder how long this will last... Already spent way to much money on UA and by the looks of it they are abandoning their loyal customers. Not a happy camper here.

Second - UAD-2 DSP Quad Accelerator Card Added

Was happy with Apollo Twin USB and then I bought the DSP QUAD Card.
OK that was good but then I found a second Quad DSP card that was used and
it works very well.
Now I can build the mixes I have wanted to do with-out resource concerns.
Happy recording!

PCIe cards still have a use,

This is about the third UAD 2 Quad card I just bought. Some people don't think the cards have any value anymore, due to UAD going Native, but for people who don't own a computer strong enough to process these plugs, that's just not true. Im running a 2012
12 core Mac Pro with Pro Tools 2019.6 ( by the way, theres an app that disables Hyper Threading and it made a HUGE difference in processing errors/crashing for PT on this machine) with 64G Ram and I have no interest in upgrading from here. Im not alone. My system is stable, it handles all the VIs I use AND with 12 processors, I can run a ton of my 61 UAD plugs without issue. Im set!

Oldie But Goodie

Bought it secondhand for cheap. It's my second one. I don't know why, but plugins powered by sharc dsp sounds better to my ears. And my i7 cpu is happier than ever.

Problems with apollo X4 and pcie

It seems that there is an imcompatibility with these two units. When the pcie is plugged in I can’t see my apollo X4. When I unplugged the pcie I see it. I’m using windows 11pro on a motherboard asus Rog Maximus XIII Hero with Thunderbolt 4.

Upgraded my 4 core to 8 core

I've been using UAD-2 cards, Apollo interfaces, and UAD plug-ins for over 10 years and love them. I originally bought a Quad card, then another... I'm upgrading the card from 4 core to 8 card for some of my massive mixes so I don't have to render. I'll be replacing another 4 core card in the near future,

It's an excellent product.

UAD DSP-powered plugins have a more transparent and textured sound, which I really love

Badly needed!

I already have the Apollo 8 quad, and I really love the dsp plugins both for realtime proscessing and for mixing. Got the quad card to increase the horsepowers for more perverse usage of realtime effects. Especially for using the marshall and Diezel plugins as Impulse response plugins on post mixes then the dsp amount is badly needed! Thnx again Universal Audio for making my creative realm even bigger!

Using it with a Asys Egpu chassis connected to my Apple silicone setup and works flawlessly

Great Card

Great card,. Although I’m having a slight issue as I have to boot the computer twice for it to load drivers. I haven’t contacted support as yet as maybe something simple. Excellent bandwidth and better than my previous FireWire satellites . So far so good , would recommend .

The extra portion power during the mix session

The PCIe Quad Accelorator delivers the extra amount of DSP power for mixing and mastering songs. Very happy with that!
