Troubleshooting
If you experience difficulties, read this section first. It contains tips on how to resolve various problems.
Can’t close the connection with the R-4
If you’re using Windows, and Explorer or any other software that is referencing the R-4’s hard disk is open
when you attempt to close the USB connection between the R-4 and your computer, the error message “An
error occurred while removing USB mass storage device – Unable to close device ‘unspecified volume’.
Please execute Stop Device again later.” will appear, and you will be unable to disconnect the R-4.
Close all software or windows that are referencing the R-4’s hard disk. Then execute “Safely remove hard
disk” once again.
CompactFlash card inserted in the R-4 is not visible from the computer
The CompactFlash card inserted in the R-4 will not be directly visible from the computer. This means that
you won’t be able to manipulate projects within the CompactFlash.
Can’t record
You won’t be able to record correctly if the input level you specified using the input level knob is too low.
Please set the input level correctly.
Refer to: “Adjusting the input level”
(p. 28)
Nor will you be able to record correctly if the input level select switch is set incorrectly. Please set the input
level switch correctly.
Refer to: “Input level select switches”
(p. 16)
If you’re recording from a connected mic, make sure that the mic is correctly connected to the combo input
jack.
Also check the setting of the input level select switch and the phantom power switch.
Refer to: “Phantom power switches [PHANTOM POWER]”
(p. 10)
“Input level select switches”
(p. 16)
You also won’t be able to record correctly if the system setting Input Select is wrong.
Refer to: “System settings”
(p. 60)
Strange sounds are heard during the recording
If you’ve recorded via the internal mics, you may hear metallic, mechanical clicks in the recording. These
sounds are the operating noises of the R-4’s internal hard disk. Due to how the R-4 is constructed, the hard
disk operating sounds may affect the recording.
You can alleviate this somewhat by using the
Graphic EQ
effect on the
REC
side to lower the 2 kHz and 4
kHz levels.
Recorded sound is distorted
The sound will be distorted if the input level is too high. Refer to
“Adjusting the input level”
(p. 28), and
use the input level knob to adjust the level appropriately.
In some cases, the sound may be distorted because you’ve applied an effect while recording. You should
adjust the input level with the effect applied. Adjust the effect parameters so that distortion does not
appear.
