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
Separate Channels (A B C D)
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
Bridged (A+B) and Separate (C D) Channels
For A+B (Bridged)
Use one 2-wire cable connect to:
• 1+/1- on connector #5
For C & D (Separate)
Use two 2-wire cables connect to:
• 1+/1- for CH C on connector #3
• 1+/1- for CH D on connector #4
Bi-amp operation, use one 4-wire cable connect to:
• 1+/1- for CH C on connector #3
• 2+/2- for CH D on connector #3
