Glasshouse Ladder Stepped Attenuator (mono version)

Glasshouse Ladder Stepped Attenuator (mono version)

As an alternative to the shunt, series type of stepped attenuator we now offer a ladder type of stepped attenuators. This is where 2 resistors 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.

We offer a stereo and mono version built on either the Seiden, 2 pole 23 way or the Elma 2 pole 24 way switch for the MONO version. The options on the resistors used are either the Takman metal film or carbon fim resistors in 0.25W or 0.5W ratings. 10K, 20K, 50K, 100K and 250K available. Built up or in kit form. Although a higher price and with a higher resistor count than the Shunt type, the ladder type provide a constant impedance through out the entire volume range. The down side is you have to use another switch contact.

We do offer the stereo version too.
