Roland R-88 用户手册

Troubleshooting

You cannot record correctly if the input setting is not set correctly.

When recording from connected microphones, make sure that the microphones are properly connected to the XLR input 

jacks. Also check the setting of the Phantom power switch.

p. 8, p. 28

Recording is not possible if the SD card is not inserted correctly. Turn off the power, and re-insert the SD card.

The SD card will not work properly unless it was formatted on the R-88. If the card was formatted using a computer, it 

might have the wrong format. In this case, it might stop immediately after recording is started, or recording might not 

occur correctly.

Recording will not be possible if the SD card has less than 1M bytes of free space.

p. 66, p. 72

You can’t record from IN 5–8 when the sampling rate is 192 kHz.

When recording a two-track mix, the recording will be at a low volume if the [MASTER] knob is turned too low.

If PRE-REC is on, the sound will be recorded starting at the point before you press the [ ] (REC) button.

The sound will be distorted if the input level or the input sens is too high.
Refer to “Input Level and Input Sensitivity Settings” (p. 31), and adjust the level appropriately.

If the output of the internal mixer is distorted, adjust the channel faders of the mixer, or adjust the master fader.

p. 43, p. 46

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

p. 28, p. 32

The R-88 will automatically divide the project if the file currently being recorded exceeds a size of 2 GB.

–

If the [MONITOR] knob is turned too far down, the volume may be too low for you to hear. 
Gradually increase the [MONITOR] knob.

If the [MASTER] knob is turned too far down, the volume may be too low for you to hear.
Gradually increase the [MASTER] knob.

p. 6, p. 46

If the output assignments are not set appropriately, sound is not output.

Make sure that your headphones or speakers are connected correctly.

Make sure that <MENU>

Ú

<OUTPUT SETUP>

Ú

<SPEAKER SW> is ON. No sound is output from the internal speakers if 

this setting is OFF.

No sound is output from the internal speakers if headphones are connected.

To prevent acoustic feedback, no sound is output from the internal speakers except during playback.

If you inadvertently disconnect the adaptor or remove the SD card during recording, the project will be damaged and 

cannot be played. In some cases you may be able to use the project Repair function to recover it.

If you record more than 2,000 projects in a single folder, projects exceeding 2,000 will not be visible in the R-88’s finder; 

however, they have been captured correctly as recorded data, and can be transferred to your computer via USB.

Make sure that the file name is assigned correctly. The R-88 cannot use files that have a name that begins with a “.” (period). p. 35, p. 54

The R-88 can only play files with a file name extension of .WAV.

A damaged file cannot be played. You might be able to recover the file by using the Repair function.

The R-88 cannot directly play files from the external memory device. In order to play a file located on the external memory 

device, copy the file onto the R-88 SD card, and then play it.

As you repeatedly write and delete project files, the files on the SD memory card become fragmented, and this slows 

down the processing speed. If you continue recording in this state, the message “SD Card Slow” is shown, and skips may 

occur in the recorded project. If making important recordings, you should consistently delete all projects together when 

finished with them. Repeated deletion of data causes the SD memory card to become fragmented, possibly causing 

recording to fail.
