Impedance Jumper Settings for Identical
Impedance
How to use the impedance jumper setting chart:
1)Determine the minimum amplifier impedance (typically either 4- or
2)Next, determine the impedance of a single speaker that will be used. Use the
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. Both jumpers must be changed appropriately (see diagram in Fig. 1)
