Total load on amplifier Note: Refer to amplifier specifications for proper loading
This chart can help you determine what load (ohms) is present on the amplifier when using multiple cabinets.
- To use this chart with two cabinets (A and B), find cabinet A’s impedance (ohms) column and cabinet B’s
impedance row on the chart. The total load on the amplifier is shown in the box where they meet. For example: If
cabinet A’s impedance is 8 ohms and cabinet B’s impedance is 4 ohms, the total load on the amplifier would be 2.67
ohms.
- To use this chart with three or more cabinets, find the total load for two cabinets and then use the result for
cabinet A’s impedance column. The third cabinet will then be used for cabinet B’s impedance row on the chart.
Find the total load on the amplifier and repeat if more cabinets are used. For example (using 3 cabinets): If the first
cabinet (cabinet A) has an impedance of 16 ohms and the second (cabinet B) has an impedance of 8 ohms, the
total load would be 5.33 ohms. Using this load (5.33) as cabinet A’s impedance and a third cabinet’s (new cabinet
B) impedance of 4 ohms, you would find that the total load on the amplifier is 2.29 ohms. Note: It is not
recommended to use any combination of cabinets that has a resulting load in a shaded area of the chart.
