Manually Variable Attenuators

Manually controlled variable attenuators are passive devices that require no external power source to operate.  A majority of our models have rotary knobs for manual control.  Just turn the knob(s) to set the desired attenuation.  We also offer manual attenuators with pushbutton, rocker or toggle switches as the manual controls.
