See Figure 3
The P5 RCA-type output connectors are compatible with most power control amplifiers. As always, select high quality audio interconnect cables. Connect the left and right channel outputs of the P5 to the corresponding inputs on the amplifier or other component.
NOTE: There are two sets of RCA outputs on the P5. The second set of outputs may be used in custom system configurations to drive a second power amplifier or to supply a signal to a special signal processor.
Balanced (XLR) Output e
See Figure 4
Two pairs of XLR balanced connectors supply an analog output signal from the P5 to a power amplifier with XLR balanced input connectors.
NOTE: Do not connect both the RCA and XLR to the same control amplifier at the same time.
