| Note |
| * 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. |
| * Cannot use this product for the signal line using phantom 48V. |
| * This product is an attenuator of the types to change resistance. Therefore, a switching noise may occur. |

| Max. Attenuation | Maximum attenuation without Cut off point. | |
| Attenuation types | BTS-50dB: Look at
specifications. Ex) 1dBx10: 0, 1, ...(1dB step)..., 9, 10dB |
|
| Impedance | Total resistance (Potentiometer), Input / Output Impedance (other circuits) | |
| Frequency Range | Operating frequency range. | |
| 1step angle | The angle to the next
decrement point. Total rotational angle = (Number of steps) x (1step angle) |
|
| Total Number of steps | Determined by
the Circuit and Attenuation types. Total number of contacts = Total number of steps + 1 |
|
| Stepper option | With: With Clicks | |
| Cut off | Cut off attenuation. Please see the cut-off attenuation specification. |
|
| Direction of attenuation | CCW:
Attenuation decreases with the clockwise (Up to Signal level). CW: Attenuation increases with the clockwise (Down to Signal level). |
