And a unique glass-reinforced-nylon manifold is molded in halves, joined together by ultrasonic welding, then cloaked with a form-fitting foam noise attenuator .
Unlike a volume potentiometer, an attenuator ensures that the sound quality remains constant: the left and right imaging doesn't shift with different volume settings.
The multiplexer with variable optical attenuator is another design that has pulled together several functions.
The company claims that moving the attenuator reduces distortion and noise.
Most of the work going on globally in integrated polymer components is in the areas of switches, attenuators , filters, modulators, lasers, and amplifiers.
