Please check before use.
* Solder heat resistance: 350deg C max, 5sec max, 2 times. (Manual soldering only)
   The solder please use the thing of the same composition. (Solder for wire lapping sticks to a terminal.)
   Use solder: SN100C (Sn-0.7Cu-0.05Ni-Ge) NIHON SUPERIOR CO.,LTD.
* Special order of the shaft length is possible. Please contact us for details.
* It is highly recommended that the fault tolerant system is to be set up in the big situation like the live broadcast.
* Replacing it from other brands tests it enough, and please consider.
* This product is an attenuator of the types to change resistance.
   Therefore, a switching noise may occur.
