From the seller
Selling my Universal Audio Apollo x4 QUAD (1st Generation). This interface has been absolutely babied its entire life in my personal studio and has never given me a single issue. Everything functions perfectly, and it's been an exceptional piece of recording equipment.
The only reason I'm selling is that I'm simplifying my studio setup, and the Apollo x4 offers considerably more I/O and processing power than I currently need.
This is a fantastic interface for anyone looking for professional-grade conversion, excellent microphone preamps, and the ability to record and monitor through UAD plug-ins with near-zero latency.
