Comparison chart mpressor rack vs

How does the rack version of the mpressor compare to its younger sibling, the mpressor 500?

The voltage rails and the availability of space are certainly dierent in the 500 series format, therefore some

adaptions had to be made. However, the true essentials which make an mpressor what it is have stayed

the same: The complete sidechain and the discrete VCA element which is based on a transconductance

topology.

Because of the limited space and connectors of 500 series modules, certain functions are only available on

the rack version, but the mpressor 500 also comes with certain exclusive advantages, mentioned below.

Some parameter ranges (especially ratio and release) have been tweaked to make the mpressor 500 a little

bit more ‚universal‘ than its bigger brother, with longer release times and a ner ratio resolution for the less

extreme settings.

Impulse response

Not a single 500 series rack in the market today comes even close when looking at the power supply of the

mpressor rack. It is fully linear, well ltered, built with extreme amounts of capacity and the nest compo-

nents available. This means that while the mpressor 500 is really good at it, the rack version is even superior

in handling impulses and providing a super tight transient response.

Headroom As a result of the different voltage rails in the 500 series format (+/-16V) and the rack version (+/-30V) the headroom of the mpressor rack is higher: • Rack version max level: Input +25 dBu, Output +27 dBu • 500 version max level: Input +21 dBu, Output +22 dBu Niveau Filter The mpressor rack comes with the Niveau Filter EQ, generating very useful and unique filter curves with a set of just two controllers.
