Glasshouse Ladder Stepped Attenuator (Stereo version)

Glasshouse Ladder Stepped Attenuator (Stereo 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 the stereo version built on either the Seiden, 4 pole 23 way or the Elma 4 pole 24-way switch or the all-new Blore Edwards 2 pole 23 way, using either the Takman Metal or Carbon resistors in 0.25W or 0.5W ratings. 10K, 25K, 50K, 100K and 250K are available. Built 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 throughout the entire volume range. The downside is you have to use another switch contact.
