Quantum ES 4 4 x 4, 24-bit / 192 kHz USB-C Audio Interface With STudio One Pro Software

Literally love this thing. It solves sooo many problems I've had with Scarlett and Zoom interfaces in the past. It doesn't pop speakers when it comes on, at least not when consistently powering with USB. The Fender input jacks are so nice for guitar recording, definitely notice a difference. It is a bit of a fingerprint magnet but it looks cool, it works great, it sounds great, and the auto-leveling feature is awesome!

I really like this interface. It's sleek and modern and high performing. Plenty of inputs and outputs for home / small studio use. The pre-amps are dynamite and the auto-gain function is nice for quickly setting up an input channel! Incredibly low-latency drivers on Windows 11. Very flexible routing options, including routing different channels to each headphone jack. I will say that I picked up some noise on the headphone ports, which I traced back to my laptop. Used a power isolator (iFi iDefender Max) to fix. Not an issue with this audio interface. The USB data, however, is digital and not impacted by noise from your laptop. I'm *very* close to taking away one star, however, for being so picky... so, so, *so* picky... when connecting via USB-C! There's a convenient USB connection state light on the top of the interface: blue if connected to driver and amber if not. Connecting the interface to various Thunderbolt hubs failed to connect. Connecting via a USB-C hub uplinked to laptop via USB-4 @ 40 Gb/s also failed to connect. So, it's not just Thunderbolt. I could connect the ES 4 directly to the same Thunderbolt and USB-4 ports on my laptop and the interface initialized just fine. Also, using a USB-C to USB-A cable was a lot less picky, connecting through USB hubs just fine. In the end, even though your audio interface can't begin to touch USB speeds, I suppose it's to burn a port on your PC, for the lowest latency and cleanest signal path. I also really appreciate the free access to Presonus Studio One Pro 7 for 6 months. I'll still purchase it, but I get to play with their money for half a year. This interface and Presonus Studio One Pro are a match made in heaven and absolutely worth the money! A very hearty "buy" recommendation. Like now. Go buy it. Right now. :)

Super clean preamps and excellent functionality. Glad I bought it.

Nothing in the box and no mention of it. The device itself is cool but haven't used it enough yet. Update: I worked through the normal type of setup issues and the device works as advertised. HOWEVER: Once I received and registered the interface the subscription for the 6 months of Studio One + did not appear as described in the set up instructions. I opened a ticket with their support team and was made to jump through hoops and provide my receipt and a picture of the back of the unit even AFTER it had already been registered to my account. They were rude then just stopped responding. I went back to customer service at Amazon and was treated respectfully and provided with a resolution I could agree with NO THANKS to Presonus. I have been a user of Studio One for many years and now I really am sorry I went down this road. I have bought software and hardware products from them for years not to mention the time and effort learning their platform. Forewarned is forearmed.

*** UPDATE *** I tried in another DAW (Luna) and had zero latency. I went back to Fender Studio Pro and went through each and every applicable setting. I switched-off Dropout Protection, which was on because I couldn't get above 8-10 tracks without experiencing dropouts. I'm still not certain PreSonus, or at least Fender Studio Pro, are going to be the right path for me. I'm bumping this up to four stars for the time being, but this has not been a super-awesome experience thus far. Very poor latency. I am really disappointed in this device. I still have my original Windows XP Pro system from 2007 with an AMD Athlon, Sonar, and my original PreSonus Firestudio firewire interface here and I can't believe how poorly this new model behaves. I'm running Fender Studio Pro on a Lenovo Windows 11 Professional laptop with 64 GB of RAM, an AMD Ryzen 7 7735HS CPU, 1 TB NVMe SSD, and the USB C cable is connected directly to the laptop. Monitoring suffers sever latency with default Studio Pro settings @ 512 Samples. Switched Dropout Protection to 'Maximum' and 'Use native direct monitoring instead of hardware monitoring' to overcome *some* of the latency, but it's still extremely noticeable. For example, plug-in a 1/4" TS instrument cable to the front instrument port and add the Fender Mustang 'amp' to track 1. Insanely slow, very high latency. In order to play in any comfortable manner, you have to switch-off monitoring and just play 'acoustically', which defeats the purpose. I can plug my old Line 6 POD directly in to my old PreSonus Firestudio and have a zero latency interface. The microphone inputs aren't any better. I thought a slapback delay was on at first, but it's just the latency. I'm going to give it a bit more time this weekend and reach out to support, but I do not seem to be alone in this latency, according to Google searches. Starting to have buyer's remorse about going with PreSonus. Also, I purchased quite a few UAD plugins and dear lord, you really cannot use these with Fender Studio Pro as the CPU usage is so high. You're lucky to get away with six to eight tracks before dropouts occur.

Confío en los productos de Amazon porque me han salido como la expectativa que tenía, alta calidad!

Excelente lo recomiendo

The product is really good. I'm happy with the recording quality

Me gusta mucho y funciona perfecta. El acabado en metal oscuro queda mejor que en las fotos. Electrónicamente es una maravilla.

Avevo presonic studio One e volevo provarlo con la scheda usb srmpre della presonic. Infatti è un' ottima accoppiata, perfettamente compatibile.

Preamp select button has 1-2-2-4 it should be 1-2-3-4

Wie erwartet, ein super Produkt von Presonus! Weitaus mehr Funktionalität als erwartet. Sehr ansprechendes Design und leichte Integration. Wer mit Studio One arbeitet, wird hiermit zufrieden sein. Die Integration in Studio One, bringt weitere Funktionen mit sich und erleichtert die Arbeit. Auch im Jamulus erledigt es alle Aufgaben wie gewünscht.

I am using this with Studio One now Fender pro DAW and it is great. Very clean signal and very low latency.
