Display is not shown

The DIMMER (DIMMER BRIGHTNESS) setting is at 0%.

Set the DIMMER (DIMMER BRIGHTNESS) setting to 25% or higher.

The display indication disappears if the unit is not operated for a time.

To protect the display, the display indication disappears 30 minutes after the PC-D/DI series unit was last operated.

To bring back the display, press any front panel key or turn the knob.

Display is dim.

The PANEL SETUP screen’s "BRIGHTNESS" is set to a low value.

Set "BRIGHTNESS" to a high value.

When no operation is performed for a time, the AUTO DIMMER function automatically dims the screen.

To bring back the display, press any front panel key or turn the knob.

Power does not turn on. Power suddenly turns off, and immediately turns off even if you turn the power on again.

The power supply voltage of the connected AC outlet is significantly outside the allowable range.

Connect a power supply of the appropriate voltage.

The interior of the amp is at a high temperature, perhaps because an obstruction or dust is blocking the ventilation and impairing the cooling.

Check the ventilation status, and take measure to ensure cooling. Then, after waiting for the unit to cool down, turn the power on again.

The output level is too high.

Lower the output level.

The sound from the speaker is distorted.

The input level exceeds the input sensitivity setting.

Using the AMP SETTINGS screen’s SENS./GAIN setting, adjust the input sensitivity appropriately for the input level.

Sound is muffled. High frequencies are not output.

A filter is applied. The filter status can be viewed in the HOME screen’s SP PROCESSOR page.

Use X-OVER to change the filter settings.

No sound from the speakers.

A cable is not connected correctly. If the meter does not rise even when you raise the volume knob, there could be a problem with the input connection. If the meter does rise, there could be a problem with the output connection.

Correctly connect the input jacks and output jacks. For the output connection, also check that you are connected to the jack that is outputting the signal.

The output is turned down on the mixer connected to the input jack. This is possible if the meter does not rise even when you raise the volume knob.

Raise the mixer’s output.

The level is lowered by the volume knob.

Adjust the volume knob.

The mute function is on. In the HOME screen you can check whether the mute function is on.

Turn off the mute function.

The protection circuit has operated to mute the output. If the protection circuit has operated, the display indicates [PROT], and the indicator of the corresponding channel flashes red.

Check the operation log to determine the reason that the protection circuit operated, and correct the cause.

Panel operations are not possible.

Panel lock is enabled.

Defeat the panel lock function. For the method, refer to " To defeat panel lock ."

You want to return the parameter settings to their initial values.

To return to the initial settings, execute " Returning to the factory settings (Initialization) ".

The edited current parameter returns to the unedited value when the power is turned off and the unit is restarted.

The power was turned off before the current parameter was automatically saved.

Before turning the power off, wait at least three seconds after an editing operation.

Can’t patch the unit with a CL series digital mixer using Dante Controller.

The CL series unit’s Fs setting is 48 kHz, and this unit’s setting is 96 kHz.

In Dante Controller or on this unit, set the Fs to match the setting of the CL series unit.

When you execute Clear Config in Dante Controller, operation becomes unstable.

After Clear Config is executed, the unit will not operate correctly until it is restarted.

If you executed Clear Config, you must restart using one of the following methods.
- When executing Clear Config in Dante Controller, put a check mark in [Reboot]
- After executing Clear Config, turn this unit’s power off and then on again
- After executing Clear Config, execute UTILITY > REBOOT from the screen of this unit
