Beale Street VCSI Impedance Matching Volume Control, Slider Knob

Description

The VCSI is a slider control automatic impedance matching volume control. That means multiple volume controls and speaker pair can be connected to a single, appropriately powered amplifier. It also means there are no impedance tables, jumpers or switch settings to mess with.

Let's say you want a simple, multiroom audio system where all speakers are playing the same thing and each room has a separate volume control.
