Speaker Input/Output:  
This is a “volume” control for the  
horn. To disable the horn, turn the  
knob counter clockwise until the  
indicator reaches :. To set the horn  
for maximum output, turn the knob  
clockwise until the indicator reaches 0.  
These jacks can be used as an input  
and/or output. They accept standard  
Speakondtype speaker cables. To  
connect a cable: Insert and twist one  
quarter turn clockwise until the release  
button locks. To remove a cable: Pull  
back release button on cable connector,  
twist connector counter clockwise one  
quarter turn, and pull out connector.  
Note: When using these jacks as an  
output to another cabinet, refer to the  
Amplifier Loading Chart (page 4) for  
important amplifier loading information.

Speaker Input/Output:  
These jacks can be used as an input  
and/or output. The jacks accept a  
standard ¼” cable. Note: When using  
these jacks as an output to another  
cabinet, refer to the Amplifier Loading  
Chart (page 4) for important amplifier  
loading information.

Total load on amplifier Note: Refer to amplifier specifications for proper loading  
information.  
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.
