Incredibly Versatile 500 Series Opto

Inspired by the granddaddy of tube leveling amplifiers, Acme Audio’s Opticom XLA-3 has taken the pro audio world by storm. Now for our 500 Series devotees, Sweetwater is excited to present to you the Opticom XLA-500. Acme has meticulously shoehorned the XLA-3’s topology into a convenient 2-space module in your favorite format. The Opticom XLA-500 delivers the richly fat and warm sonic character you expect from a traditional tube optical limiter, along with impressive speed and versatility that will surprise (and delight) you.

From clean to mean

The XLA-500’s forgiving handling of vocals and instruments makes it your reliable go-to for any source. But unlike opto compressors of yore, the XLA-500 is no one-trick pony. With tones on tap that range from clean and transparent to harmonically rich to saturated and dirty, and compression curves that range from slow and gentle to very fast and aggressive, the XLA-500 is incredibly versatile.

From gentle to aggressive

The XLA-500 has Normal, Fast, and Slow modes. In Slow mode, its traditionally gentle attack onset passes initial transients largely intact — key to the subtle transient enhancement and dynamics control you want from a conventional opto compressor. So yes — it does that. But the XLA-500 is so much more. Its proprietary triple optoelectronic circuit blends the most desirable characteristics of three different compression curves into a single unit. Combine that with a Class A gain stage and CineMag input and output transformers, and you have a high-speed optical limiter that can approximate the performance of FET designs.

Easy to get great-sounding results

The Opticom XLA-500 is certainly one of the most versatile 500 Series optical limiters we’ve seen. Whether your goal is to gently control the dynamic range of a vocal, add thickness and weight to a bass guitar, or mercilessly crush a drum track, you can effortlessly achieve it all with the XLA-500, producing a wide range of great-sounding, nonlinear dynamic effects to suit any musical setting.

Acme Audio Opticom XLA-500 Tube Optical Limiter Features:

  • Normal, Fast, and Slow modes
  • Impressive tonal versatility
  • The most desirable characteristics of 3 different compression curves in a single unit
  • Triple optoelectronic circuit
  • Class A gain stage
  • CineMag input and output transformers

Reviews

An absolute gem!!!
I own several other high end 500 series compressors and this is by far my favorite of the bunch!!! It offers so much flexibility. The mid speed is great for an LA2A flavor, and The fast (1176 all buttons in mode) is fantastic on everything!!! I agree with the poster above. This little gem deserves a lot more praise. This could easily be my desert island comp.
How does this not get more attention?
Love the LA-2A flavor on vocals but don't want to spend four grand on one? Get this. Period. Put it on Fast, turn both knobs near twelve o'clock, and you're 90% there. This lives in my vocal chain between a 1073 and a Maag EQ4 and it never disappoints.

XLA 500 has everything I expect from Opto Compressor
This 500 series opto compressor brings up the RMS of track very musically while putting a unique LA2A-ish color on the tracks. I've compared this with other LA2A plug-ins. Although XLA 500 doesn't boost up the low-ends like other LA2A plug-ins, but it boost up the sounds most naturally rather than overemphasizing particular frequency. Also speed toggle switch gives very different outcomes, so it's like getting 3 different LA2A-ish compressor with reasonable price.
