Amazing But Needs Windows Performance Improvement

The Apollo Solo USB Heritage Edition I purchased has been the best upgrade to my home studio since I upgraded my mic. This audio interface is hands down amazing, just would be nice too not have any latency issues on windows. The plug-ins that came with it are hands down incredible, they make my old waves versions look like a joke. Overall an amazing product, just slight performance issues on windows.

little..

The reason why I tried to give you 4 stars but took one out is because of compatibility with Windows. I don't know if my computer is a problem, but I think it's not enough to get along with many computers. Please pay attention.

Not a good fit for Windows users latency still an issue with windows, over heats often

I wouldn't recommend it for windows users but if you have a mac get it, If you have Windows you will still have latency issues, it also over heats even when it is not under a load. It should come with a USB cable but doesn't, bad management because if the user has a crap USB cable it will make the product perform bad. Fix these three things and I would say it is the best on the market. top quality hardware. Why they have not ingirted their recording software with windows is also a sign of bad management making the product look bad when it could be the best on the market.

Love this Apollo USB thing

So….I was in the process of upgrading my ten year old and ultra reliable RME Babyface and 2012 MacBook Pro …
I was looking at buying a Thunderbolt Twin due to the conflicting views on the UA USB support and driver for the Apollo units -I picked up a Dell Latitude 5490 laptop for a great price and decided to “take a chance” and see if I could save the cost of buying a new Mac…ordered the Apollo Solo USB heritage edition.
I’m pretty Mac an PC “literate” so set up the Dell as per all the usual Windows tweaks -processor scheduling,USB hub power etc…setup the Apollo Solo with a decent USB cable -initial tests,amazed at the quality of playback (the RME is no slouch,but this was like night and day sonically …)

Crackle in playback …oh no …

Checked the console sample rate matched the Cubase project sample rate …

Amazing.Rock solid,crackle free,amazing sound…unison preamps ?What can you say ?

Bought the Avalon 737 and Neve preamps on a deal.Just sound incredible with my AT 4047 mic.The Heritage plug-in are just superb,the quality of the Unison plug ins are a revelation-so much so most of my hardware is now up for sale!

I love this thing.It’s literally as good as the “real” stuff to my jaded ears.

What I would say is that it helps if you know a little about configuring PC’s- the setup advice that’s out there is good,do a bit of research and use a “quality” USB cable…

Apollo Solo USB Believer

Using this with PC and it is running very smoothly. I was worried after reading some reviews on UA not working well with PC, but wanted to try Universal Audio DSP and plugins and am extremely happy with the results! Great sounding vocals come easy using Unison and Avalon plugin with just a touch of LA2A compression and recording direct. I find that I have to add very little eq to the initial recording, which is what I’ve been looking for over the years. It just has “that” sound going in. The sound quality, headroom and quality of UA plugins has made this a game changer for my sound and ease of mixing. Wish I had made this decision before now!

Birkaç yanlış anlaşılmayı düzeltmek için yazılmıştır!

Öncelikle solo ve twin ve diğer üst modeller arasındaki kıyaslamalar yanlış bir mantıkla yapılıyor.
1. Apollo solo endüstriyel kalitede dönüştürücülere sahipken diğer üst modeller dünya standartlarında ( endüstriyel kalite ile dünya kalitesi arasındaki fark nedir ? Birkaç DB ses aralığı ve minimal fark derecesinde dinamik aralık çünkü dünya standartları endüstriyel standartlara Parelel şekilde belirlenir.)
Bu demek oluyor ki solo aldığınızda bu konuda birşey kaçırmış olmazsınız.
2.DSP farkları ; Solo ve diğer büyük ürünlerde çekirdek farkı bulunmakta .
Sesinizi temiz bir şekilde kaydedip daw üzerinde karışım ve master yapacaksanız bunun bir önemi yoktur .İşte mesele tam olarak burada .Solo aynı preamp( unison preamps) kullanır ve size vokal ve enstrüman kayıdında büyük abileriyle aynı ses kalitesini sunar ve endüstriyel kalitede dönüştürücü ile size aradığınız kaliteyi sunar .
Önemli olan mesele ,siz ne için bakıyorsunuz , ihtiyacınız nedir ?
Dünya kalitesi mi? ( Mix ve master ile bunu zaten yakalarsınız)
Ayrık kulaklık amfileri zaten tarafsız , güvenli ve güçlü bir izleme olanağı sunar .
Solo ile örneğin temiz ve kaliteli bir vokal ve gitar kaydı alır ve bunu harika şekilde mix ve master yapabilirsiniz.Gereksiz kıyaslama ve bilgi kirliliğinden uzak durun . İhtiyacınız minimal ve üst düzey bir ses kartı ise buyrun doğru ürün budur !
