Impedance Jumper Settings for Identical Impedance
How to use the impedance jumper setting chart:
1) Determine the minimum amplifier impedance (typically either 4-
or 8-Ohm). This information can usually be found next to the
speaker outputs located on the receiver or amplifier. If in doubt,
consult the receiver and/or amplifier instruction manual.
2) Next, determine the impedance of a single speaker that will be
used. Use the left-most column.
3) Move to the right of the chart and find the number of speaker
pairs that you plan to connect to the volume control.
4) Finally, move up the column to the very top row. This row will
provide the jumper setting solution. Change the jumper on the
volume control to complete the impedance jumper setting
procedure. (Factory setting is X4)
