Khozmo Series Attenuators

Effectively a long chain of resistors whose sum equals the selected impedance. The switch wiper moves through the chain as the volume knob is turned. Like a potentiometer, the input impedance of a series type stepped attenuator remains constant, so the signal source always sees a constant, non varying load.

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: 6 mm
Indexing angle: 7,2 deg

Note:  when ordering, please let me know what impedance you need.  Options range from 600 ohms for pro audio use, all the way to 240K.   The price is the same.  I cannot tell you which one you need.  That is up to the design of the piece of equipment.  You are safe if you swap the same value impedance.
