Problem What to check Page
Sound played by
your computer is
inaudible or too soft
Could the monitor select switch be in the inward position (headphones only)?
If this is set to headphones only, the output of the main output jacks will be
muted.
->”8. Monitor select switch” (p. 11)
p. 11
Are any channels muted or soloed?
If mute is turned on, that channel will not produce sound. If solo is turned on for
a channel, the other channels will not produce sound.
Clear the mute and solo settings as described in “CLEAR MUTE/SOLO” (p. 60).
p. 60
Try adjusting the audio buer size of the driver
If the size of the driver’s audio buer is too small, sound may not be produced,
or it may be impossible to carry out normal playback and recording.
In such cases, you should refer to “Driver Settings” (p. 69), and increase the size of
the buer.
p. 69
Insucient volume
from your guitar
Are you using the correct connector?
Connect your guitar to the INPUT 2 combo input jack.
p. 35
Is the input impedance select switch set correctly?
Set the input impedance select switch to the Hi-Z position.
p. 36
Is the input level appropriate?
Try turning the OCTA-CAPTURE’s [SENS] knob toward the right to increase the
input level.
p. 33
Could you be using a cable that contains a resistor?
Make connections using a cable that does not contain an internal resistor.
–
Also check the contents of “Insucient volume from a device connected to the
input jack.”
p. 86
Insucient
volume from your
microphone
Is the input impedance select switch set correctly?
Set the input impedance select switch to Lo-Z.
p. 36
Are you using the correct connector?
Connect your microphone to the XLR type connector of the combo input jack.
p. 35
Also check the contents of “Insucient volume from a device connected to the
input jack.”
p. 86
Is the volume of the direct mixer set appropriately?
Use the”Control Panel” (p. 43) to view and adjust the volume of the direct mixer.
p. 43
Insucient volume
from a device
connected to the
input jack
Is the [INPUT MIX] knob raised appropriately?
Turn the [INPUT MIX] knob toward the right to adjust the volume.
p. 39
Is the input level appropriate?
If you’ve connected the device to combo input jacks, try turning the OCTA-
CAPTURE’s input sensitivity knob toward the right to increase the input level.
p. 37
Is the volume of the direct mixer set appropriately?
Use the “Control Panel” (p. 43) to view and adjust the volume of the direct mixer
p. 43
Could you be using a cable that contains a resistor?
