Troubleshooting
Problem Confirmation Resolution

Was the DUO-CAPTURE connected to
the computer while the computer was
starting up?
Connect the DUO-CAPTURE after the computer has
started up.
(With some computers, the DUO-CAPTURE cannot
be used if it is connected to the computer while the
computer is starting up.)
Did the computer perform a processor-
intensive task while you were using the
DUO-CAPTURE?
Stop playback or recording, and then try playing
back or recording again.
If the problem is not resolved, exit all programs
that are using the DUO-CAPTURE, disconnect the
DUO-CAPTURE’s USB cable, and then reconnect it.
No sound from
computer’s
speakers
This is not a malfunction.
When using the DUO-CAPTURE, no sound is heard
from the computer’s speakers.
Connect headphones to the DUO-CAPTURE.
Cannot play
audio using digital
connection
Is the sample rate setting correct?
Make sure that the digital device’s audio sample
rate setting matches the DUO-CAPTURE’s sample
rate setting.
After changing the DUO-CAPTURE’s sample rate,
exit all programs that are using the DUO-CAPTURE,
disconnect the DUO-CAPTURE’s USB cable, and
then reconnect it.
Noise heard when
playing guitar
Does the noise decrease when the
guitar’s volume is turned down?
Move away from the computer.
Recorded sound is
too quiet
Is the input level raised?
Use the [INPUT VOLUME] slider to increase the input
level. If your software has an input level adjustment,
check the input level setting.
Is the [Hi-Z] switch set to “OFF”?
When recording a microphone connected to the
MIC/GUITAR jack, set the [Hi-Z] switch to “OFF.”
Is the [Hi-Z] switch set to “ON”?
When recording a guitar connected to the MIC/
GUITAR jack, set the [Hi-Z] switch to “ON.”
Are you using a cable with a built-in
resistor?
When connection cables with resistors are used, the
volume level of equipment connected to the inputs
(LINE IN, MIC/GUITAR) may be low. If this happens,
use connection cables that do not contain resistors.
Does the sensitivity of the microphone
match the input level of the DUO-
CAPTURE?
The DUO-CAPTURE’s microphone input level is -45
dBu. If the sensitivity of the microphone is low, the
sound will be quiet.
