Khozmo Stepped Attenuator, Stereo, 48 steps, SMD Ladder version.
Ladder type stepped attenuator
This is where 2 resistor and 2 switch contacts are used per step, making up a unique combination of resistors per step that add up to the impedance of the stepped attenuator you use. Effectively a voltage divider network.
The total series resistance of each two resistor set is equal, so the signal source always sees the same impedance.
- Switching type: MBB (Make Before Break)

- Attenuation range: -60 dB ... 0 dB
- Attenuation per step: steps 1 to 11 - 2dB, 12 to 48 - 1dB
- Contact material: Hard gold
- Polished wiper and contact pins
- Extremely short signal path

The resistors are Royal Ohm SMD 1% 1/10W, thin film, metal, surface mount. The stepped attenuator offers incredibly good value and outstanding performance.
How to change torque: Use a 2mm hex key (allen key). Set the position to 24 (start from zero volume and turn up) insert the hex key. Turn clockwise to increase torque and anti-clockwise to decrease torque.
