Note

* Solder heat resistance: 350deg C max, 5sec max, 2 times. (Manual soldering only) * Please take care during soldering that the smoke from the solder does not flow inside a fader. * If the flux sticks to a resistor board, it may cause a trouble with the fader.

* Move to one end in Control-bar on the occasion of knob wearing, and can break into it slowly.

* It is highly recommended that the fault tolerant system is to be set up in the big situation like the live broadcast.

* This product is designed on the assumption of the horizontal use. * The enough operational testing is highly recommended for the slant or the vertical use to prevent the unexpected operation.

* Replacing it from other brands tests it enough, and please consider.

* Caution in Ladder circuit(Audio and AP taper) use.    Important points in using audio curve and log curve of TKD faders >>

The load resistance (R) on the fader output side should be much higher than 20 times the total resistance value. During fader operation, due to noise generated from friction between resistive elements and contacts and noise generated from vibration of the power mechanism, there are many factors affecting the output signal quality. To reduce these effects, use decoupling capacitors (C). (Use a capacitor value that matches the control circuit to which it is connected.)

* It is recommended that motor leads be shortened and twisted.   Consider not to interfere with other motor leads.

* Color may vary slightly due to body material. * Due to the way the body is processed, there may be some rubbing on the folded parts.

* Please do not strike the fader carriage hard against either end of the fader. * Please do not stop the fader keeping the fader carriage pushed hard against either end of the fader.
