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!

Love it!

My second Pci card. Just doubled my production power. Now I can have a eq on all my channels, without using my cpu.

uad 2 pcie

so far I tried lexicon 224 and akg bx 20 - very unique reverbs. this is my first step into the uad ecosystem, so more to follow

My arrival at the uad plugins, was through the purchase of the LA 610 mk2 analog hardware purchase a few years ago, it was a revolution for my windows-based system, it allowed me to raise the level of my music.
I still prefer your plugins to those of other brands because above all the analog emulations are very successful, I have some in real hardware that I use in my projects completed with your plugins, that's why I have acquired more cards to have more power and it has been satisfactorily noticed .
My collection of plugins has increased considerably now having almost everything I need without leaving your platform.
In addition to all this, the updates are a pleasure and how fast and well everything works.
Thanks Universal audio for the great work you do.

Great little addition to my solo

I own a Solo, which is great for tracking, but it immediately made me want a little more power for mixes. This is a fantastic way to expand on your setup and open up a lot more options. Super easy to install, just slotted it in and it immediately worked. Very happy.

Must Have

So, I was going back and forth between PCIe and USB versions of the accelerator. With USB version, I can take it anywhere and it means I can use UAD plugins wherever I go. Yet the downside of the USB version is space: you need space for USB connection, an adaptor, and the USB box itself (and one day when I turn it on and off too often, then the switch may break). With the PCIe card, I can save space and have no worries about the switch. I just can't use it anywhere (and I don't know whether it will be compatible when I upgrade my computer). Finally, I decided to go with the PCIe card because each system can only have the maximum of two USB accelerators, but more than two PCIe cards if needed. This card is a champion. I can save a lot of space and have no worries about setting up the optimal USB setting for the USB version. Since it connects straight to the mainboard, it is very quick in action. I got two of them in my system and plan to buy a third one as I still have one more PCIe slot. In short, I love this item.

Does what it says on the tin

I built a new studio PC and this one was really a no brainer as I have 79 UAD plugins to choose from.

Octo PCIe card

Works as advertised. Popped it straight into my Highpoint PCIe/TB enclosure, no problem. Now I'm able to utilize my Capitol Chambers and Ocean Way plugs as I'd like in my mixes. Only quibble is that you can't use the DSP chips during recording, only the ones in the Apollo interface.

Audio awesomeness

Bought mainly for the Studer A800 and Ampex mastering tape plugins.
Really happy with the results - as close to tape as you’re going to get without using tape. And it doesn’t weigh 400 kilos.
Really impressed with the Ocean Way plugin too.
I like the platform, the activation process is pretty good. It’d be better if unregistered plugins could be de-selected from the UA console so that they wouldn’t show in your DAW without manual intervention.
I love being able to purchase outright, and not on a subscription model.
UA plugins are awesome!
