4.7. ETERNAL Crossfader

The ECLER ETERNAL Crossfader is an inductive fade technology based on a magnetic control.
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.
The ETERNAL Crossfader also features new "Tuning" features that will give the HAK380 the
most accurate Crossfader adjustment :
- Slope adjustment (58). These potentiometers, located at the front part of the unit, allow the adjustment
of the slope from soft to hard at each of the crossfader's ends. The setting for one end is independent
from the other end's setting.
- REVERSE switch (59). Inverts the crossfader's direction. Depending on the selected direction it is
possible to perform "cuts" as well as "transforms" moving the crossfader in the same direction.
- Electronic CUT IN TIME correction (57). The "cut in time" is the distance between the top of the
crossfader and the first signal input point. The shortest position provides a nearly instantaneous "cut in
time". To find this position, the crossfader must be on one of its tops (musical program completely
cancelled) and the CUT IN TIME potentiometer must be turned right until the musical signal is
recovered. To obtain a longer "cut in time" the potentiometer must be turned left. The HAK380 has two
independent CUT IN TIME controls, one for each end of the crossfader.

4.8. SCRATCH CUE function

By activating the SCRATCH CUE function (36) it is possible to pre-listen the operation of the
crossfader on the headphones without affecting the main output. This means, if the function is activated,
the crossfader's operation on the main output "freezes" on one of its tops. From this moment on, moving
the crossfader does not affect the MIX signal.
By activating this function, the following happens:
- The function is implemented directly on the headphones signal. This signal will be, independently of
the position of the FX/PGM/PFL switch, the PFL from CH1 and CH2 after the MONITOR MIX, which
depends on the crossfader's position.
- The VU-meters will read the PFL signal (L+R) from CH1 and CH2 as advised by the LED (46).
- The MIX signal remains affected by the crossfader until this will be moved to one of its tops. Until this
moment, the LED (37) lightens up red and once the crossfader has reached one of its tops, this
"unhooks" from the MIX signal and the LED turns green.
