Avalon AD2055

The Avalon AD2055 is a 2U rack-mounted Class A dual-mono 4-band parametric EQ.

By combining both active and passive filter elements the Avalon AD2055 is capable of great definition in operation and yet remains transparent and uncoloured. The Class A design helps there too, keeping the signal path uninterrupted and the signal strong all along the line. Because the high and low frequencies on the Avalon AD2055 are switchable and the mids are fully parametric, you can zero in on just the information that you need and bring out all the detail.

The layout of the AD2055 from Avalon Design is very user-friendly and intuitive and the controls naturally fall under your fingers whenever you need to make an adjustment. It is this approach to design that has kept Avalon at the forefront of studio technology since its inception. The Avalon AD2055 units are very popular amongst recording and mastering engineers all over the world.

Avalon Design likes to take a simple concept and just make it better. The Avalon AD2055 is a perfect example of this - when something is made with the best quality components and put together with absolute musical performance in mind, you get what you pay for - the best.
