The XL-K1 is a replacement kit for the channel fader knobs on early 442 and 442N field mixers. XL-K1 knobs provide positive visual and tactile feedback on level adjustments to the mixer operator. The circular detents provide a protected space for the included color inserts.
The included circular color inserts can be placed in the knob detent to color-code mixer channels. Four dots of each color are provided to color-code the channel knob, equipment output, and cable. These mylar color inserts won't wear off the mixer face or discolor with age.
