“I’m loving the new Gen 2 Apollo Xs! The added monitor control for a sub and Apollo Monitor Correction are going to be game changers. I’m finding that using a 50% correction for my setup still makes sense for what I’m used to in my space but the image is improved.”
– Jacquire King (James Bay, Kings of Leon, Tom Waits)“Gen 2 Apollo Xs are a serious upgrade. The preamps are still open and clear, but they sound smoother and more detailed. Plus, Sonarworks room correction built in is a huge leap forward!”
– Vance Powell (Chris Stapleton, Jack White, Arctic Monkeys)“The Apollo Monitor Correction is the easiest way to guarantee the most accurate listening environment. With NO latency!”
– Fab Dupont (Shakira, Santigold, Jennifer Lopez)“The converters on the Gen 2 Apollos sound detailed and punchy without any harshness, and with the addition of Sonarworks I can get consistent studio-level results anywhere in the world.”
– Eric J Dubowsky (Flume, ODESZA, Chris Lake)Downloads
