Universal Audio does it again

Since it's released in 1967, API’s 550A and 560 EQs have been a signature sound on many records over decades. It's crisp and natural sounding characteristic have made a signature sound both on API mixers and Productions.

Some of the high selling points of the 550b EQ are its simple but incredibly versatile four-bands and its ‘proportional Q’ characteristic. The bandwidth reduces as the gain is increased, effectively allowing for broad, subtle strokes of tonal adjustment or more precise control of specific bands when making heavier boosts and cuts.

Some comments made about these incredibly EQs are,

  • A 550A is always warm, big and huge, soft like a big pillow, but on the negative side also a bit smearing.
  • A 550B is always bright and clean. flexible. tons of possibilities. great for hifi 80ies-BDs, too! Sounds great when boosted a lot! And everywhere, where You wouldnt want your sound smoothed out. Bright SDs, e. g.
  • A 560 is always a bit sort of phasey. It's a sharp shaper. You design sounds with that tool, rather than adapt them to other sounds. You can cut 12dB on one frequency band and it still sounds great! The 550A is a colour, the 560 is a workmans tool, but one of the nicest and best in the market out there! I have 8 of them!

I myself am a fan of API gear including its API preamps. So for now please go straight to the Universal Audio website and download you're free API EQ package and listen to what it is all about.
