6． In dual channel mode, if there are more than 4 zones and the total power rate is more than
500W, 4 external power amplifiers need to be connected as follows:
Use a twisted-pair cable to connect the PA interface "CH1" of the RK-ZONE8 to the PA
-
interface "IN" of the first power amplifier.
Connect the "100V" and "COM" output of the first power amplifier output port to "CH1A IN"
-
of the RK-ZONE8; "COM" output connects to the "CH1A IN -" input.
Use a twisted-pair cable to connect the PA interface "OUT" of the first power amplifier to
-
the PA interface "IN" of the second power amplifier.
Connect the "100V" and "COM" output of the second power amplifier output port to "CH1B
-
IN" of the RK-ZONE8.
Use a twisted-pair cable to connect the PA interface "CH2" of the RK-ZONE8 to the PA
-
interface "IN" of the third power amplifier.
Connect the "100V" and "COM" output of the third power amplifier output port to "CH2A IN"
-
of the RK-ZONE8.
Use a twisted-pair cable to connect the PA interface "OUT" of the third power amplifier to
-
the PA interface "IN" of the forth power amplifier.
Connect the "100V" and "COM" output of the forth power amplifier output port to "CH2B IN"
-
of the RK-ZONE8.
