Khozmo Stereo Ladder Stepped Attenuator, 48 step, SMD

Khozmo Stereo Ladder Stepped Attenuator, 48 step, MKII SMD

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) 
  • Number of steps: 48
  • 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
  • Channel matching: +/-0.1 dB
  • Resistance: 5K, 10K, 25K, 50K, 100K, 250 kohm
  • Mechanical life: > 50 000 cycles
  • CNC machined PA11 aluminium body
  • Precision ball bearing support
  • Shaft diameter x length: 6mm x 15mm
  • Bush diameter x length: 9 mm x 10mm
  • body dimension: 52mm (height, including exposed PCB) x 42mm (width) x 69mm (depth, front to back)
  • Indexing angle: 7,2 deg
  • Available in 10K and 100K versions.

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.
