This is an awesome device. I used this as a compressor and expander back in my metal tape days. It got the most use extending the range on my vinyl LPs though. I’m still in the market to replace the one I sold in the 80s.

DBX II Model 128 Dynamic Range Enhancer and Noise Reduction System

I like this device but it has more features than I need. I prefer the simplicity of the 117, 118, and 119 models. The added buttons and noise reduction don’t really do anything for me. Like the other models I referenced the 128 can do the same expansion I like on my vinyl records as well as the compression to tape and then expansion from tape. You big tape heads might prefer the extras on the 128 but I like the small boxes. The best news is, you can usually pick up a model 128 for less than a DBX 119.
