Re: Help Installing Speaker Volume Controls ...

[robertlbass@xxxxxxxxxxx]

Most impedance matching volume controls have a selectable impedance
multiplier.  If you were to select "4X" on each of your VC's you'd have
1/Rt = 1/32 + 1/32 + 1/32 which is 10-2/3 Ohms and safe for your
amplifier.  Selecting "2X" on all three would yield a net impedance of
5-1/3 Ohms, too low for the amp.

But wait...  If you have one room that is larger / needs more volume
than the other two.  You could set that room for "2X" and the other two
rooms for "4X".  The result would be 1/Rt = 1/32 + 1/32 + 1/16, which
is exactly 8 Ohms.

The Russound V/C's I carry have an off position.  The side of the
autoformer connected to the speakers becomes an open circuit.  The
other side stays in the circuit, but draws virtually no power from the
line side because at that point there's nothing on the load side.
