Get to know them!

The mpressor 500 brings the signal-shaping prowess of elysia’s acclaimed rackmount mpressor to the 500 Series format. Streamlined for the space constraints of a single-wide module, the mpressor 500 is mono and lacks the EQ circuitry of its bigger brother, but as a compressor, it delivers the powerful punch, flexible dynamics shaping, and highly detailed Class A sonics you expect. Its sound and versatility make the mpressor 500 ideal for both recording and mixing, and its special features give it capabilities far beyond most conventional compressors. Like its 19-inch rackmount sibling, the mpressor 500 features negative ratios, extreme time constants, Anti Log release, and elysia’s proprietary gain reduction limiting. Unique to the 500 Series modules is switchable THD Boost harmonic enhancement, which lets you dial in delightfully gritty saturation and signal coloration.

A compressor that encourages experimentation

The elysia mpressor 500 isn’t your usual compressor — take it from Sweetwater. It’s designed to inspire and take your sounds to new sonic heights. The cool Anti Log button lets you add extra thump to your bass with a single switch. An Auto Fast button changes your attack speed to the fastest setting possible for getting great sounds in a flash. Mix the functions of the elysia together, and you can create innovative new uses for this highly musical and tweakable compressor that blur the line between compression and effects and are especially effective for electronic music. The elysia mpressor qube gives you two of these amazing compressors. Experiment and enjoy!

elysia mpressor 500 Compressor Features:

  • 500 Series compressor with 100% Class A circuit topology
  • THD Boost harmonic enhancement for a grittier sonic flavor
  • Auto Fast attack always provides a perfect attack
  • Anti Log circuit generates explicit compression effects such as pumping and breathing
  • Negative Ratios for unique compression effects
  • Gain Reduction Limiter lets you select maximum GR with a knob twist
  • Stepped controls for quick and easy recall
  • Handcrafted in elysia’s factory in Nettetal, Germany
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
