LA9A Levelling Compressor
The LA9A is a simple, great-sounding levelling compressor for vocals, instruments and full mixes. One main dial does the heavy lifting, so you can spend less time tweaking and more time listening.
I know what you’re thinking: “Not another single-dial plugin. “, but the LA9A is more than that. Don’t take my word for it. It’s free; give it a try on your Mix or Master bus, and listen how LA9A will level your entire mix. Use the Compress dial and your ear to judge the output until it sounds right. Next, insert my Crest Factor 9 Limiter plugin, and your song Mastering is almost done.
Please note: the LA9A is an original design and is not related to, or a model of, the famous LA2A Opto Compressor.

FEATURES
- One-dial compression: just turn Compress until it sounds right
- Two modes (A and B) with different characters – try both
- Input gain, output gain and Auto Level matching
- Optional Side-Chain low-cut to keep low frequencies from over-triggering
- Stereo Input and Output meters, plus a Gain Reduction meter
- Clean, simple layout – every control is on the front panel
