Avalon AD2077

The Avalon AD2077 is a 2U rack-mounted Class A dual mono mastering EQ with swept high and low frequencies, fully parametric mids and stereo link.

If you are mastering, then the Avalon AD2077 is the perfect tool for you to pinpoint troublesome frequencies and zoom in on them. After that it's just a twist of the wrist to boost or cut them with the powerful and precise AD2077. The controls are stepped too, thus enabling you to replicate any changes at a moment's notice - no more anxious twiddling to try and match up the opposite sides.

Transparency on the AD2077 is a given, as is the superb musical performance - this is practically a hallmark of Avalon Design. Class A circuitry means that the Avalon AD2077 delivers an accurate, true signal with minimal interruptions and very low distortion.

The twin channel design means that you can use it either as two separate mono units or gang it together for stereo operation - giving you more flexibility than ever. Mastering and mixing engineers stake their reputations on the results that they can deliver, which is why the Avalon AD2077 can be found in so many studios.
