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.

Cleans Out Working Carburetors
Size: 2 fl oz
I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner. You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose. I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.

It works like magic, saved me $150.
Size: 2 fl oz
I filled 1/4 tank of gas into my snowblower which I could not started, sprayed about 15 seconds of Start Your Engines, rock snowblower to mix well, let it sat for an hour. I pulled string and yet couldn't start engine. Unscrewed spark plug and spray some into cylinder, put the spark plug back and pull the string. ENGINE STARTED!!! SAVED ME AT THE LEAST $150.

Flimsy Nozzle
Size: 2 fl oz
The nozzle is so flimsy at the moment I pressed on it it popped off the can into the gas tank. I didn’t press it softly but I also didn’t press it very hard either, getting it out was a huge pain in the butt.
