Troubleshooting
If there are problems during operation of the H4, check the following points first.
Problems during recording/
playback
◆
No sound, or sound is very weak
• Check the connections to your monitor
system, and the volume setting of the
system.
• Check whether the volume level setting
of tracks 1 – 4 is appropriate.
◆
Recorder stops during playback
• When playback is carried out with a
track in recording standby condition, a
temporary file is created in the H4. If the
remaining capacity of the SD card is
low, the temporary file may use up all
the remaining space, causing playback
to stop. In such a case, cancel the
recording standby condition of the
track.
◆
No sound from connected instrument,
or sound is very weak
• Check input source settings (
→
p. 31,
48).
• Check setting of [INPUT 1 GAIN],
[INPUT 2 GAIN], and [MIC GAIN]
switches (
→
p. 32).
• Check whether recording level setting
is appropriate (
→
p. 31, 48).
• If [INPUT 1]/[INPUT 2] jacks are used,
try raising output level of connected
instrument.
• When the monitor function (
→
p. 51) is
off, the input signal can only be
monitored if a track is set to recording
standby or if the recorder is in the
recording standby condition.
◆
Cannot record on a track
• Verify that [REC] key and key for
recording target track are lit in red.
• If a project is protected, recording is
not possible. Use another project or
turn protection off (
→
p. 58).
• Verify that an SD card is inserted in the
slot.
• Check whether the key-hold function is
enabled (
→
p. 79).
• If the indication "Card Protected" is
shown on the display, the SD card is
write-protected. Slide the write-protect
switch to the non-protected position.
◆
Cannot perform bounce
• Verify that the level of tracks 1 – 4 is not
fully lowered.
• Verify that there is sufficient free space
on the SD card.
Other problems
◆
Cannot use effects
• Check whether effect section is on. The
effect section is off by default in stereo
mode and in 4-track mode.
◆
Cannot use tuner
• Check whether the jack to which the
instrument is connected is selected as
input source.
◆
Unit is not recognized when connected
to a computer via USB
• Check whether the operating system of
the computer meets the requirements
listed on page 80.
• To have the H4 recognized by the
computer, USB mode must first be
selected at the H4 (
→
p. 81).
