Description

Universal Audio Apollo x4 Heritage Edition Audio InterfaceThe Universal Audio Apollo x4 Heritage Edition brings four Unison enabled mic preamps, QUAD Core UAD processing, and 24 bit 192 kHz conversion to a compact desktop unit that tracks through classic processing in real time. Unison lets each preamp adopt impedance, gain staging, and nonlinear behavior from emulations like the 610, API, and Neve, so tone is shaped at the source rather than patched in after the fact. I O is arranged for hybrid workflows.

The Universal Audio Apollo x4 Heritage Edition brings four Unison-enabled mic preamps, QUAD Core UAD processing, and 24-bit/192 kHz conversion to a compact desktop unit that tracks through classic processing in real time. Unison lets each preamp adopt impedance, gain staging, and nonlinear behavior from emulations like the 610, API, and Neve, so tone is shaped at the source rather than patched in after the fact.

I/O is arranged for hybrid workflows. Four front-end XLR combo inputs handle mic, line, or Hi-Z sources with phantom power on tap, and Unison support across all pres. Balanced monitor outputs anchor the mains, an additional pair of line outs covers alternate speakers or outboard sends, and two independent headphone outputs simplify artist cue mixes. Optical ADAT input expands channel count for multi-mic drums or external preamps, while S/PDIF support and Word Clock keep digital rigs coherent. Thunderbolt connectivity provides low-latency performance and integrates cleanly with multi-Apollo systems.

Monitoring and session control are centralized. A large encoder governs monitor level with dim, mute, and mono at fingertip reach, and the integrated talkback mic speeds slate and cue updates. Console software builds low-latency cue mixes, recalls routings, and lets you commit or monitor through UAD plug-ins like 1176, LA-2A, API Vision, or tape without taxing the host CPU.

Heritage Edition status loads the account with flagship UAD titles on day one, making it practical to shape tone on input and avoid plug-in roulette later. If the brief is desktop footprint, four serious mic inputs, and dependable real-time processing that scales with external preamps over ADAT, Apollo x4 Heritage Edition is tailored for that job.

No more scrolling. Best price, abundant, does its job.

I have it under the closed cell foam. It’s great. Just as great as Killmat and all the other butyl rubber products. Let me ask you to do something: look at the people who rated it 1 and 2 stars. No reviews. No pictures. Why? They don’t want to see the most budget friendly product getting sold. That’s some weak business. Rest assured you’ll be happy with this. Why did I buy both types? Butyl rubber helps the car not be a tin can. It keeps the outside road vibrations out. Closed cell phone keeps your music in. They work best together., Kumbaya, we have unity! We can get along, even in this age in time. The closed cell foam is cheap. You’ll get it to replace the nasty cloth under your carpet. Do the knock test. It won’t help. You need this too. And truth be told, I prefer that it has no name on it. I’m not paying money so you can brand yourself on my car. Ps: these products go on and don’t come off. Don’t mess up. It’s the same for the competitors and the closed cell foam. One shot. Do it right the first time. I’m writing this review after I used up my first box and am getting more. Happy returning customer.

Great stuff, well made.
Model: 36 Sqft
I was very pleased with this product. Very easy to use, flexible enough to conform to the variations of the surface (floor of the car and some side panels), and it stuck well. I topped it with a similar foam product to provide additional sound deadening. The car has not been run yet but the panels are much "quieter" when tapped on vs before with undercoating, felt and carpet. Seems well made and I expect no issues in the future.

Good inexpensive sound deadening
Model: 36 Sqft
This stuff works great, it's easy to apply, sticky, easy to cut. 36 ft.² was enough to do the inside and outside of my doors the roof, the wheel wells and rear fenders. Plus, it's a lot cheaper than others.

Very good quality
Model: 36 Sqft
Very good quality, noticeable difference after installation. The sound deadening effect is clear, with a great reduction in road noise and vibrations. Installation was quick and easy.
