AUDIO CONNECTIONS

 

The 3 Series Speakers are equipped with balanced XLR and 6 mm (

¼

") TRS inputs for connection to professional 

computer audio interfaces, mixing consoles and audio production equipment as well as unbalanced consumer 
audio products including personal music players, consumer audio receivers and audio visual equipment. Connect 
professional equipment with balanced outputs to the XLR or 6 mm (

¼

") TRS input of the speaker using balanced 

signal cables.
3-Series speakers are equipped with an INPUT SENSITIVITY SWITCH.  The switch is set to the -10 dBV setting  
when it ships from our factory. This setting will be best for many applications. However, you can set the switch  
to the +4 dBu setting:

 

    

When connecting 3 Series speakers to professional equipment with +4 dBu nominal output level, set    

 the INPUT SENSITIVITY SWITCH to the +4 dBu setting. To determine the nominal output level of the  

   

 connected equipment, consult the documentation supplied with the connected equipment.

 
 

    

If you notice the sound is distorted, set this switch to the +4 dBu setting.

 
 

    

When using the LSR310S in a system with the LSR308 or LSR305 studio monitors, set the INPUT  

 SENSITIVITY switch on the LSR305 or LSR308 to the -10dBV setting regardless of the LSR310S input  
 sensitivity switch setting.  

LSR310S Subwoofer connections  

The left and right outputs of the signal source should be connected directly to the LEFT and RIGHT INPUTS of the 
subwoofer. The LEFT and RIGHT OUTPUTS of the subwoofer should be connected to the inputs of the left and 
right speakers respectively.  

POWER CONNECTIONS

 

The 3 Series speakers incorporate a universal power supply allowing these to be used domestically and 
internationally.  The ground terminal of the IEC plug is required by wiring codes and regulations and must  
always be connected to the electrical installation safety ground.
