Connecting RK-ZONE8
Connecting Main Power Amplifiers
The relevant amplifier interface of the RK-ZONE8 has a detailed description in the
“Interface
Introduction” section. A maximum of 4 power amplifiers can be connected to the RK-ZONE8. Select
the proper connection method according to the expected application.

．
In single channel mode, if there are fewer than 4 zones, an external amplifier needs 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 power amplifier.
-
Connect the “100V” and “COM” output of the power amplifier to “CH1A IN” of the RK-
ZONE8;
“COM” output connects to the “CH1A IN-” input.

In single 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 follows:
- Use a twisted-pair cable to connect the
PA interface “CH1” of the RK-ZONE8 to the PA
interface “IN” of the power amplifier.
- Connect the
amplifier output port “100V” and “COM” to RK-MCU input port “CH1A IN”; port
“COM” output connects to the “CH1A IN-” input.
-
Connect the “+” and “-” of “CH1A IN” to the corresponding ports of “CH1B IN”.

In single channel mode, if there are more than 4 zones and the total power rate is more than
500W, the external power amplifier needs to be connected as follows:
- Use a twisted-pair cable to connect the
PA interface “CH1” of the RK-ZONE8 to the PA
interfac
e “IN” of the first power amplifier.
- 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
output port “100V” and “COM” of the first power amplifier to the RK-ZONE8
input port “CH1A IN”.
- Connect the
output port “100V” and “COM” of the second power amplifier to the RK-ZONE8
input port “CH1B IN”; “COM” output connects to the “CH1B IN-” input.
