Troubleshooting

If there is no sound or if the unit does not operate as you expect, please check the following points first. If this does not resolve the problem, contact the nearest Roland service center or authorized Roland distributor.

There’s No Sound

• Make sure the Input Level control has not been turned fully counterclockwise.

• Make sure the Input Select switch has been set to the connector where the input signal is connected (Digital

Input or Analog Input).

• Make sure the Digital Input select switch has been set to the connector where the input signal is connected

(Optical or Coaxial).

• Input a digital signal to the Digital Input connector. No sound is produced when an analog signal is input.

The volume level of the instrument connected to ANALOG INPUT is too low

• Could you be using a connection cable that contains a resistor? Use a connection cable that does not contain a resistor.

During Digital Signal Input, the Stereo

Image Is Reversed or Sounds

Unnatural, or Output Doesn’t Sound

Like Stereo

• Check the setting of the Assign switch (Right, L+R, or

Left). The DS-30A uses an identical construction for the left and right monitors, and makes no distinction between left and right. During digital signal input, set the Assign switch L or R as appropriate for your setup.
