Troubleshooting

Has a mic or guitar been left connected?

If a mic or guitar is connected to the PC-80, disconnect the mic or guitar and turn the input sensitivity knob all
the way toward the left (lowering the input level).

Have you connected the grounding terminal?

Connecting the chassis of your computer or the grounding terminal of your computer’s AC power cord to an
electrical ground may solve the problem. Also, make sure that a device that produces a strong magnetic field,
such as a television or microwave oven, is not located nearby.

Could numerous audio devices be connected?

Noise may occur if numerous audio devices are connected. Do not connect audio devices you are not using.

Is the input level appropriate?

Use the input level knob located on the PC-80’s back panel to adjust the input level.

Is the Input Mode setting appropriate?

Select the appropriate setting for your equipment as described in Setting the Input Mode (p. 83).

Is the master volume knob set appropriately?

Turn the knob to adjust the volume.

Could you be using a connection cable that contains a resistor?

When connection cables with resistors are used, the volume level of equipment connected to the inputs (Input
jacks) may be low. If this happens, use connection cables that do not contain resistors, such as those from the
Roland PCS series.

Does the noise decrease when you turn down the volume of your guitar?

If the noise decreases when you turn down the volume of your guitar, the guitar pickup may be affected by
noise from your computer or display. Try locating the guitar as far away from the computer as possible.

Is the Input Mode setting appropriate?

Select the appropriate setting for your equipment as described in Setting the Input Mode (p. 83).
