Glasshouse Ladder Stepped Attenuator (Stereo version)
We now offer a ladder-type of stepped attenuator as an alternative to the shunt series type of stepped attenuator. This is where two resistors and switch contacts are used per step, making up a unique combination of resistors per step that adds up to the impedance of the stepped attenuator you use. Effectively a voltage divider network.
We offer the stereo version built on either the Seiden, 4 pole 23 way, the Elma 4 pole 24-way switch, or the all-new Blore Edwards 4 pole 23 way, using the Takman Metal or Carbon resistors in 0.25W or 0.5W ratings. 10K, 25K, 50K and 250K are available. Built or in kit form.
Although a higher price and resistor count than the Shunt type, the ladder type provides a constant impedance throughout the entire volume range. The downside is you have to use another switch contact.

As part of the kit version, we supply 0.5m of 1mm HGC pure silver wire, 0.2m of 1mm PTFE and 2m of Mundorf 3.8% silver/gold solder.
We do offer the mono version too.
We currently cannot supply the Takman Carbon 0.25W and 0.5W 100K versions.
