ETERNAL Crossfader is an inductive fade technology based on a magnetic control patented by Ecler. An extremely light aluminium screen (0,5 gr.) cuts the flux lines of a magnetic field created between two sets of coils. This electromagnetic modulation controls an assigned Voltage Controlled Amplifier that modifies the gain/attenuation of the signal. The contactless technology is combined with a custom high quality glides mechanism to offer a very smooth touch and succeed the most accurate Crossfader system.

The ETERNAL concept does have obvious advantages upon other existing Systems using optical technology. Unlike optoelectronic elements, the inductive concept is resistant to smoke, moisture, temperature and aging. Other electromagnetic systems found on the market are particularly sensible to the lateral room of the mechanism, and have heavier mobile elements (magnets or iron plates) that add an excessive weight to the crossfader. Such systems usually have a strange feel that can bother highly precise manipulations such as Scratching and Beat Juggling.
