Roland V-Studio VS-20 用户手册

Troubleshooting

Noise or distortion
occurs

Is a guitar connected?

If the noise diminishes when you lower the volume of your guitar, it could be that your
guitar’s pickups are being affected by electrical interference from your computer or
display. Try moving your guitar as far away as possible from your computer.

Could a microphone or guitar be
connected?

If a microphone or guitar is connected, unplug the microphone or guitar and turn
[SENS] knob all the way to the left so that the input level is lowered.

Could the level meter peak
indicator be lit?

Try lowering the input level. Use the [SENS] knob to adjust the input level. Or, use REC
LEVEL knob to adjust the recording level in the VS-20 Editor.

Check connections with your other
equipment.

If the audio output of another USB device is connected to the V-STUDIO 20, noise from
your computer may be heard via the V-STUDIO 20. Try connecting via a self-powered
USB hub (a USB hub that has an internal power supply or AC adaptor) or changing the
audio output connections.

Is your equipment grounded?

You may be able to solve the problem by connecting the chassis of your computer or
the ground pin of your computer’s power supply to an electrical ground. Also make
sure that there is no nearby device that might be producing a strong electromagnetic
field, such as a television or microwave oven.

Is there a Preset or Patch loaded in
the VS-20 Editor that has heavy
distortion or other setting?

Press COSM button to bypass effect, and then check clean signal.
