+4dBV (switch IN) or -10dBu (switch OUT) to match the nominal level of the 
signal source.  If you don’t know how to set the switch, consult the documentation 
for the signal source.  Most professional devices operate at +4dBV while most 
consumer devices operate at -10dBu.  (See page 23 in this manual for  audio con-
nections and wiring diagram.)

  

Do 

NOT

 make connections to both the XLR and ¼� analog connectors; use one or  

the other.

b.  If you are connecting digital signals (i.e., from a digital console or workstation, 

or from the digital outputs of a CD or DVD player or processor), use appropriate 
cabling to make a connection between the device and the rear panel AES/EBU 
(XLR) or S/PDIF (phono) input of the speaker designated to carry the LEFT  
channel (i.e., the left speaker in a stereo setup).  Then use appropriate cabling to 
make a connection between the rear panel AES/EBU (XLR) or S/PDIF (phono) 
output of the left speaker and the rear panel AES/EBU or S/PDIF input of the 
speaker designated to carry the RIGHT channel (i.e., the right speaker in a stereo 
setup).  (See page 24 in this manual for a wiring diagram.)

  

When using digital audio inputs, the rear panel DIP switch settings determine which 

channel of the stereo AES/EBU or S/PDIF signal will be reproduced by each speaker.

 

LSR4300 Front Panel

7.  Press the front panel INPUT button on any speaker so that it begins blinking.  While it is 

still blinking, press the + / - controls on any speaker to select the desired input.  The front 
panel LEDs and the rear panel ACTIVE INPUT display shows which of the three inputs 
(Analog, S/PDIF, or AES/EBU) is currently selected.  If a digital input is selected, the rear 
panel ACTIVE INPUT display also shows which channel is being reproduced by  
that speaker.
