INSTALLATION CONSIDERATIONS
CALCULATING THE IMPEDANCE MAGNIFICATION SETTING
Use the following instructions and the accompanying charts to select the correct switch setting for the number and type of
speakers in your system.
CAUTION! EVERY SPEAKER PAIR IN THE SYSTEM MUST BE CONNECTED TO AN IMPEDANCE-MAGNIFYING VOLUME
CONTROL AND SET TO THE SAME MAGNIFICATION.
1. Count the number of pairs of 4-ohm speakers and the number of pairs of 8-ohm speakers you are connectin Count
pairs of 6-ohm speakers as 4-ohm pairs.
2. Determine whether the amplifier should see a 4-ohm load or an 8-ohm load. This information is typically found in
the owner’s manual of the amplifier.
3. Read the correct switch position from the charts on page 7. See
Figure 4 if your amplifier can drive a 4-ohm load.
See Figure 5 if your amplifier must have an 8-ohm speaker load.
4. Set the switches on all of the controls to the same position (1x, 2x, 4x, or 8x). See Figure 7.INSTALLATION
