Under the dual channel mode, if there are less than 4 zones, one external power amplifier for
CH2 need to be connected as the following steps:
- Use twisted-pair cable to connect
PA interface “CH2” of RK-MCU to the PA interface “IN”
of power amplifier.
-
Connect the “100V” and “COM” output of power amplifier to “CH2A IN” of RK-MCU, “COM”
output connects to “CH2A IN-“ input.

Under the dual channel mode, if there are more than 4 zones and the total power rate is less
than 500W, the external power amplifiers need to be connected as the following steps:
-
Connect the “+” and “-” of “CH1A OUT” to the corresponding ports of “CH1B IN”.
- Use the twisted-pair cable to connect
PA interface “CH2” of RK-MCU to PA interface “IN”
of power amplifier.
-
Connect the “100V” and “COM” output of power amplifier to “CH2A IN” of RK-MCU, “COM”
output connects to “CH2A IN-” input.
-
Connect the “+” and “-” of “CH2A IN” to the corresponding ports of “CH2B IN”.
