What the Pro’s are saying

“When you’re working with high-profile artists, you don’t want the weakest link to be the converters. With the Symphony MK II, it’s pristine. I know that if it’s Apogee gear, it’s the best!”

Andrew Bolooki

Grammy Award Winning Engineer / Producer

“The Symphony Mk II 16×16 Special Edition is the perfect tool for Dolby Atmos. It’s transparent and does everything you ask of it. I have been using to mix Jimi Hendrix in Dolby Atmos and it’s amazing.”

Eddie Kramer

Grammy Award Winning Engineer / Producer

“The heart of our system is the Symphony Mk II 16×16 and it provides a sense of clarity and depth that we haven’t found in other interfaces. We also use the Symphony Desktop on the road to retain that same level of conversion quality.”

Jordan Stilwell

Grammy Award Winning Engineer

“The flexibility and expandability of the Symphony Mk II system, Soft Limit, and the transparent sound made this choice an easy one.”
