Description
Effectively a 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.
Perfect replacement for any log potentiometer like Alps, Bourns etc.
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 kOhm
Mechanical life: > 50 000 cycles
CNC machined PA11 aluminium body
Precision ball bearing support
Shaft diameter: 6 mm
Indexing angle: 7,2 deg
Dimensions of stereo unit. Mono has 1 sectio, stereo 2, Quad has 4 sections.

Just assembled, it’s way better than previous TKD 2CP-2508 pot.
Music flows awesome, detailed and airfull.
A great upgrade indeed and a big surprise.
Thanks, greetings from Sicily.

I much preferred this attenuator in my passive preamp with Sowter step up. I had previously tried various other potentiometers, including Alps RK27, TKD 2CP2511 (very overrated, IMO), but Khozmo has much more airiness, transparency and a fantastic deep soundstage. Mechanically very precise, very reliable. No noise, pops or clicks.
Greetings from Italy.

I have justed replaced from an alps blue attenuator and the change in terms of sonics and fuctionality is superb!. The sound is clear and open and the stereo image locked perfectly between the speeker as the alps must have been not working evenly I guess. I also think I get more detail but mostly I also enjoy how the pot is working and the 48 step attenuation is a game changer for me.

Sustituí un potenciometro eizz de 24 pasos , no me hacia gracia subir el volumen de 2.5 db en cada movimiento , Lo instalé
en un amplificador Jadis , asegurarse antes de las medidas , hay poco espacio .
Los primeros días estaba todo raro , pero ya se ve la transparencia , ahora las escuchas son muy buenas y su precisión de funcionamiento , muy recomendable .

A premium quality, smooth operation, spreaded settings, precision device…
The perfect choice for replacing the stereo volume control in my 1974Audio Research SP3A1.
Model 48 steps series – 100K stereo.

Many times we believe we have reached the best level of hi-end but the road still remains open for further discovering under a simple operation. Recently I replaced the Alps potentiometer in my preamp Audio Research LS 22 with the Khozmo Series Type 48 Steps Mechanical Attenuator. Seems like comparing the night to the day.My LS 22 is close to 30 years old, been upgraded with Black Gate, Mundorf, Relcap and Auricap capacitors and new fast diodes, but I didn’t expected such an astonishing difference after a simple but so essential replacement like the Khozmo attenuator. All results are beyond any standards and critics. The holographic scene is amazing, the details are so significant and clear, the bass is more punchy and controlled, the mids and voices are so close to touch them and the trebles are silky without any exaggeration.And the breaking-in time is not done yet.All the other copmonents from CD to the Power Amps and Speakers unfolded and revealed all the sonic virtues of their own. Unbelievable transfiguration, copmletely. Great congratulation to the Khozmo company and especially to the owner Arek Kallas.Very serious and perfect work. Many many thanks again for such a precious gift to audiophiles worldwide.
