UAD Powered Plug-Ins Manual - 45 - Chapter 3: API 500 Series EQ Collection
CHAPTER 3
API 500 Series EQ Collection
Introduction
The 550A and 560 modular EQs are some of the most popular and enduring
mixing and tracking processors ever made. The 500 series modules from API
are true industry standards, found in professional multi-channel consoles to
Lunchbox racks in the humblest of project studios. Designed by the now leg-
endary Saul Walker in the late 60s, the combination of Walker's 2520 op
amp and his Proportional Q circuitry gave the 550 and 560 an uncompli-
cated way to generate acoustically superior equalization.
Universal Audio now offers the UAD-2 platform true best-in-class emulations of
these two audio production staples. With UA’s industry-leading circuit model-
ing that captures the filter shapes, band interactions, and unique filter ampli-
fier clipping behaviors providing full “suspension of disbelief,” these plugins
fulfill sonic requirements that previously only the API hardware could provide.
Based on vintage units provided by Ross Hogarth and Capitol Studios, both
plug-ins provide era-specific features and behaviors, and a remarkable model
of API’s custom 2520 and output transformer — the results are fantastic low-
frequency transparency and tight imaging, which is that legendary API
“punch in your gut” sound. Like with the hardware, the EQs are extremely fast
to set, reliable and uniform, and deliver that one-of-a-kind API high headroom
precision.
If you want the sound of classic American music, you need the API EQs.
