Black Lion Audio Seventeen 500 500-Series FET Limiting Amplifier & Compressor


Manufacturer's Description

It’s not your grandpa’s ‘76.

Seventeen 500 is Black Lion’s 500-series spin on what the classic ’76 compressor could have been. Featuring a redesigned and improved IC-based front end, Seventeen 500 renders incredible detail and nuance normally not possible with a ‘76-style comp—while adding some features unavailable on original ‘76s.

What makes Seventeen 500 different?

First, Seventeen 500 features a new IC-based front-end circuit not found in classic ‘76 compressors. It provides a clean, punchy, modern sound under light compression and a more colorful vintage character when pushed. That front-end, when coupled with our custom-designed, made-in-Chicago output transformer, is why Seventeen delivers a huge bottom end that balances out its open top end very nicely. All told, Seventeen 500 is capable of delivering a broader tonal palette than original ‘76s.

Seventeen 500 features BLA’s proprietary Black Lion-style power decoupling for an incredibly low noise floor. It also uses high-grade Nichicon signal capacitors, widely considered some of the highest quality caps available, reducing the noise floor even further.

Black Lion could have stopped there... but why? Other features and upgrades include: a frequency-adjustable sidechain; separate selectable high- and low-pass filters; and a wet/dry mix knob parallel compression straight out of the box. Beyond offering a palette of tones not available to anything else on the market, Seventeen 500 also includes the all-important stereo link function.

Last but not least—yes, it does “all-buttons-in” mode, and we’ve made it much easier to engage multiple ratio controls simultaneously than on classic models.


Sorry for the mix-up - we’ve been made aware of some issues with the Seventeen 500 marketing assets which included some misinformation. We have updated the sales kits, dealer copy, press kit, print ads, and brochures with the following changes:

  • “USA-made transformer” has been corrected to “custom-designed Black Lion output transformer”
  • References to “separate selectable high- and low-pass filters” have been removed. These filters exist on the original 19” rackmount Seventeen, and not the Seventeen 500.
