4-Band Analog Stereo Equalizer Module

The Missing Link

The xfilter 500 is a true linked stereo EQ in the 500 series format. It gives you the expensive sound of an all class-A equalizer in a surprisingly affordable package, with a precise stereo image based on computer-selected, stepped potentiometers and low tolerance film capacitors.

With its exceptionally open sound, straight transient projection and solid punch, the xfilter 500 is the perfect match for your xpressor 500 – or any other piece of outboard gear!

5 reasons why you should use the xfilter qube

Build Quality

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

Class-A Topology

Consequently represents the art of discrete signal processing.

True Stereo Link

As one of the few exceptions in the market, the xfilter 500 processes both of its channels with just one set of controllers – a true stereo linked EQ.

Computer-Selected Potentiometers

Every single dual and quad layer pot we buy is measured with custom computer routines, and only the lowest tolerance ones go into production.

Low Tolerance Capacitors

The special series of film caps used for the xfilter performs twice as good as the industry standard in terms of component tolerance.
