Universal Audio Apollo x4 & Twin X

soundonsound.com

Universal Audio's Apollo x4 emerges as a formidable desktop audio interface, offering four mic preamps and ample I/O options for serious tracking needs. The upgraded power supply is a welcome improvement, enhancing usability. However, the absence of a Thunderbolt cable is a notable oversight. While it delivers superb performance and flexibility, users transitioning from previous models may find the lack of groundbreaking features somewhat underwhelming. Overall, the x4 is a wise choice for professionals seeking robust recording capabilities in a compact format, despite minor drawbacks.

Universal Audio Apollo x4 review | MusicRadar

With a seductive feature set and superb audio quality, the Universal Audio Apollo x4 stands out in the crowded interface market. It boasts four Unison-enabled preamps and extensive UAD effects, enhancing both recording and processing capabilities. However, it lacks the flexibility for surround sound configurations, which may disappoint some users. Overall, it's an attractive choice for those needing robust I/O options without stepping up to pricier models.
