Glasshouse / Seiden 4-pole 23-way switch / Balanced Stereo Shunt Stepped Attenuator
The 23-pole Seiden range of switches is beautifully crafted. It offers a smooth turning action, quality contact materials, gold-plated silver, and a dust cover on all the contacts so you won`t suffer from noisy switching. The body is non-magnetic. The price is also reasonable. It's a great switch to use for any stepped attenuator.
This version offers 23 volume positions from mute to near total volume through our tried-and-tested 2dB step values of resistors. The switch's front does possess a "non-turn" lug of 3mm x 1.5mm that protrudes from the front panel. See the wiring diagram in the link below for the front panel drawing. This can be removed with cutters if not required.
We offer the option to choose from 16 different resistor types for this kit.
SERIES/LOAD RESISTOR FOR SHUNT TYPE
The series/load resistor of the shunt stepped attenuator range is worth discussing. All the signal passes through this resistor no matter your position on your volume control. So, this resistor is worth an upgrade. A popular choice is the Charcroft Z-Foil range or Audio Note Non-Magnetic Tantalum. If you wish to upgrade them, add them to your cart. x1 for a each mono, x2 for a stereo and x4 for a balanced. Choose the resistance close to the impedance of the stepped attenuator you buy. For example, for a Stereo Shunt 50K, you would have to add 2 off the CART 50K000B: 50K 0.4W Charcroft Z-Foil Resistor. If you are ordering a built version, mention in the comments box that you wish to have them fitted.
