Action
The DUO-CAPTURE EX's microphone input
level is -60 dBu for the XLR connector, and
-46 dBu for the TRS phone type jack. If the
sensitivity of the microphone is low, the
sound will be quiet.
Change the DAW software's settings so
that it records in monaural.
Turn the [SENS 1] or [SENS 2] knob toward
the left to reduce the input level (p. 7).
Exit programs that are not in use.
If the software allows you to adjust the
audio buffer size, change the buffer size.
Refer to the documentation for your
software.
Increase the USB driver's audio buffer size
(p. 31).
If audio drops out or if noise is heard even
if you have adjusted the audio buffer size,
increase the "Recording Margin" setting
(p. 32).
Run Windows Update or Microsoft Update
and make sure the system software is up
to date.
Run Software Update and make sure the
system software is up to date.
Update to the latest USB drivers.
Install the latest LAN hardware drivers.
If the problem is not resolved, disable the
LAN.
