Infinity™ Fader
The First truly Optical Fader
The Infinity Fader™ is a Industries worldwide patented design and
completely changes the way audio mixers work.
The Infinity™ Fader is the world's first truly 100% optical fader. Previous concepts
have always required a stiff shaft to pull electrical contacts along a circuit board. Though
these variable resistive faders have been used for many years there have always been some
basic drawbacks with the design. Because the fader has to drag contacts along a circuit
boards the fader has significant drag in it’s motion. This design also breaks down over
time and can require the fader be replaced on a regular basis if the fader is used for
scratching.
The Infinity™ Fader solves both problems
by removing the path of resistance by contact.
It incorporates an LED, photo sensor, and a
blocking fader shaft.
The LED transmits light to the photo
sensor. Between these two parts is a blocking
fader shaft that travels on a track of the
smoothest steel ball bearings. This steel fader shaft
changes the amount of light it blocks as it moves
across the path of the LED. The more the blocking
fader moves in front of the LED, the amount of light
received by the photo sensor is reduced. This
information is then translated into various levels of
gain control within the mixer. The fader shaft itself
has no audio or electrical parts attached to it to wear
out. This revolutionary Friction Free concept achieves
the cleanest sound with the absolute fastest and
smoothest cuts.
