Your RQ-970 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). [. . . ] Connect a set of cables between the outputs of the RT-520L and one of the line level inputs of the amplifier. As always, use high quality cables and be sure to connect the Left and Right channel outputs of the RT-520L to the correct channels of the amplifier. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes.
