Outputs
The PLD amplifi ers have four confi gurable outputs. You can set the power, combine outputs (bridged and parallel), and adjust the DSP for each 
output. When the output confi guration of the amplifi er changes, the output connections, controlled by relays, change accordingly. Use the diagrams 
shown in 
Figure 5
 thru 
Figure 7
 as a reference for wiring the loudspeakers
.

For Four Separate Cables
Use four 2-wire cables, connect to:
•  1+/1- on connectors #1 thru #4
For Bi-amp Operation
Use two 4-wire cables, connect to:
•  1+/1- for CH A and 2+/2- for CH B     on 
connector #1
•  1+/1- for CH C and 2+/2- for CH D     on 
connector #3
