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.

Attenuation types
 
BTS-50dB: Look at specifications.
Ex) 1dBx10: 0, 1, ...(1dB step)..., 9, 10dB
ImpedanceTotal resistance (Potentiometer), Input / Output Impedance (other circuits)
Frequency RangeOperating 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 optionWith: 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).

Method of ordering
1. Can estimate the standard lineup product only with the order number.
2. In the case of the specifications product which a standard lineup does not have, there are two ways of estimate methoES.

    a: Method to change a part of the standard lineup specifications

        a-1: Please inform it of the order number and specifications change point.
               Modifiable point: Cut off (With / Without), Stepper option (With / Without), Impedance, Control shaft length

        a-2: Examine production possibility with designated specifications before an estimate.

        a-3: Inform it of the model number and an estimate.

    b: Special order specifications

        b-1: Please inform it of specifications of the hope.
              (Cannot change the basic electric specifications such as input levels.)
               Modifiable point: Cut off (With / Without), Stepper option (With / Without), Impedance, Control shaft length, Circuit, Max.Attenuation,
               Attenuation type

        b-2: Examine production possibility with designated specifications before an estimate.

        b-3: Inform it of the model number and an estimate.
