Futuristic Dynamics

The Elysia mpressor is a powerful instrument for modern dynamics processing. On top of the tried and tested standard features, this creative compressor provides several special functions that produce fat sounds with maximum punch, beautiful colorations, and extreme processing options. Besides classic tracking applications, its favorite domains are groovy effect compression and creative sound design.

5 reasons why you should use the mpressor

even there are many more!

  • Build Quality

    The mpressor, just like all our products, is designed, engineered, and handcrafted in Germany.

  • 100% Discrete Class-A Technology

    Consequently represents the art of discrete signal processing.

  • Auto-Fast

    Switchable semi-automation that always provides perfect attack and release.

  • External Side Chain

    This enables the compressor to control its processing totally independent of the audio material running through it.

  • Gain Reduction Limiter Feature

    This limiter is not placed in the audio path where you would usually find it but in the control path of the compressor.

Build Quality

elysia quality is all about details.

Every single of its many aspects – sound, features, circuitry, components, design, materials, manufacturing – has been thought over and over until there was just nothing left to improve. Basically, every single part of our products is custom, and most of these are made according to our own designs and specs.

Only the best components the market has to offer are good enough for our products, and it shows. Each of our products is manually built to order and tested by ourselves, here at our headquarters in Germany.

The benefits sum up in an audio quality that is beyond all doubt. Even when extreme settings are used, the sound always stays clean and powerful.

Unique Possibilities

The circuit design of the mpressor is completely based on discrete analog technology. The entire signal processing is based on single transistors in permanent class-A mode, and even the sidechain and power supply are fully discrete circuit designs. Covering all the standards at ease, the mpressor offers an amazing set of special features that reach far beyond the possibilities of regular compressors.

Auto Fast

The attack parameter is a very crucial factor for the operations of a compressor. Choosing the right time settings is very important, but depending on the dynamic progress of the source material this can be a difficult task – no matter if single tracks or complete mixes are processed.

If a very short attack time is chosen, the compressor is able to catch the short peaks, but on the other hand, the sustaining signal will also be processed, which might result in audible distortion. Longer settings reduce distortion significantly, but then the compressor is too slow for catching fast impulses.

This is where the Auto Fast function comes into play. For example, if you set the attack to 80 ms and then engage the Auto Fast mode, the attack time will be shortened automatically on fast and loud signal impulses. The compressor reduces the signal quickly and prevents it from slipping through.

Then the attack time directly and automatically returns to its original setting. In Auto Fast mode the compressor can be very fast, but only when it is really needed. This function influences the attack parameter on short and loud impulses only; in all other cases the original setting of the controller has priority.
