UAD Powered Plug-Ins Manual - 496 - Chapter 51: UA 610 Tube Preamp & EQ Collection
The UA 610 Plug-Ins
The UA 610 Tube Preamp Collection is comprised of two distinct plug-ins, as
shown in
Figure 159 on page 495 : The vintage UA 610-A, and the modern
UA 610-B. Each plug-in has its own modeling and each captures its unique
segment in the 610’s sonic history.
The complete signal path is modeled for both 610 plug-ins, including tube am-
plifiers and transformer components, along with all the phase shift and distor-
tion characteristics that are inherent in each hardware preamp.
Vintage 610-A The original 610 Modular Amplifier had two versions; the 610 and the
610-A. Besides minor cosmetic differences (such as updates to the panel lay-
out and the UA logo), the only circuit difference between the two was the ad-
dition of a +3 dB setting to the 10 kHz High Shelf EQ.
The UA 610-A plug-in models the vintage 610-A module in the original Wally
Heider “Green Board” console.
Modern 610-B The 610-B is the modern Universal Audio preamp design used in our popular
hardware products such as the 2-610, LA-610mkII, and 6176.
The UA 610-B plug-in is modeled from the Universal Audio 2-610 Dual Chan-
nel Tube Preamplifier hardware, including all the expanded features opti-
mized for modern use.
In Use A primary use for either 610 plug-in is for individual vocal or instrument tracks
where colorful tube character and broad EQ strokes are desired. The 610 is
widely used as a vocal, bass, horn or strings channel by many modern users,
but it sounds great on any source signals, as proven by over five decades of
record making.
Tonal Range From clean to clipped, with a broad sweet spot between, extreme tonal flex-
ibility is possible with the 610-A and 610-B. The input and output circuits
each have their own tube-driven gain stage, and because each stage imparts
its own color, many variations can be obtained by tuning the I/O gain struc-
tures. The UA 610 equalizers can also add lots of flavor. Because the EQ has
a feedback-style design, it effects the distortion characteristics of the output
stage.
