Sound Pure's Take

“The beauty of the Elysia Xpressor is its flexibility. Compression ratios from 1.2:1 all the way beyond infinity into negative ratios, a sweepable side-chain filter that goes all the way to 1kHz, gain reduction limiting (look this up immediately), and the rack mount version even has side-chain inputs for when you want to duck the mix with your kick or help the bass guitar and kick drum coexist more easily. It's got a clean, open signal path, but when you need character you can really lean in hard and get a lot of great compression artifacts, all while being able to dial it back to planet earth with wet/dry blend and gain reduction limiting.”
- David Barrett, Sound Pure Pro Audio Specialist

*****
We’ve never been one to lightly throw out the “L” word, so you can trust that when we say this we truly, sincerely mean it with 100% of our being - we've fallen in love with the Elysia Xpressor.  
So what exactly is it about this 2-channel dynamics processor that’s convinced us to utter such a powerful 4 letter word? Well, for starters, you have a wet/dry mix knob, a feature we're surprised more compressors don’t include despite the incredible versatility it provides. You’ve got a “warmth” button to quickly add some extra analog tone to your signal (great for beefing up your drum bus or vocal tracks), as well as a selectable side-chain filter to help ensure you’re not getting any mix bus pumping from your heavy-hitting kick. But what really separates this compressor from the rest of the two-channel dynamics processors out there is the incredible power and control that comes from the greater than infinity (negative) ratios and the “GRL” or Gain Reduction Limiter knob. That’s right, negative ratios, meaning the output volume actually gets pulled below your threshold any time the incoming audio exceeds your set threshold. While this naturally lends itself to create some pretty aggressive sounds, setting the GRL knob to restrict the amount of compression to just a few dBs can result in some very usable sounds within even a more traditional, less effect-heavy mix. 
We’ve been using the Xpressor on drum bus pretty extensively (we’d love to try it on other sources, but we’ve only got one and we just can’t bring ourselves to pull it off our drum bus!). Sonically, the Xpressor covers a HUGE range of characters - it can be a very smooth, transparent bus compressor used to bring up your RMS level without any standard compression artifacts (with ratios as low as 1.2, the Xpressor can definitely do subtle, if that’s what you’re after). It can also get incredibly punchy and heavy-hitting. Just check what it does to the drum track in Elysia’s demo video - it does not disappoint.
