TROUBLESHOOTING
Please refer to the following list of common troubleshooting scenarios if you run into
problems.
PROBLEM CAUSE SOLUTION
Speakers not plugged in. Make sure that the speakers are
connected to a live power source.
Speakers not turned on. Make sure that the speakers are turned
on. The blue LED will be illuminated
while the speakers are on.
Speakers not connected to
computer. Make sure that the speakers are
connected to a functioning USB port on
your computer.
Problem is caused by use of a
hub. We strongly recommend that you avoid
using USB hubs and connect the
speakers directly to your computer.
Headphones are plugged in. Remember that while the heaphones
are plugged in, the speakers will not
output audio. Disconnect the
headphones if you would like to listen
through the speakers.
Speakers do not work.
Volume is all the way at
minimum.. Turn up the volume knob on the front to
a suitable level.
I am only hearing audio from
the left speaker. Right speaker not connected. Make sure that the right speaker is
connected to the left speaker with the
included 1/8“ cable.
Gain levels of your input
sources are too hot. Turn down the audio level of your input
sources. This is extrenely important
when using multiple sources, as the
inputs on the rear panel of the speakers
will be summed together before
entering your computer. I am experiencing distortion
when recording from external
sources.
Software monitoring has not
been truned off and is causing
a feedback loop. Make sure that your software
monitoring is turned off when recording
from external sources to avoid
feedback and distortion.
Buffer size in your software is
set too high. Set the buffer size to a lower value.
This is usually done in your software’s
Audio settings or perferences. I am experiencing a lot of
latency or “lag“.
The class-compliant audio
drivers are insufficient. Download the free ASIO4ALL driver
from
www.asio4all.com . It may help
achieve better results under extremely
low latency settings.
I am experiencing audio
dropouts and glitches. Buffer size in your software is
set too low. Exteremely low buffer sizes can result
in your computer working harder than it
can, causing unwanted dropouts and
glitches. Select a higher bugger size in
your software to avoid this.
My software DAW is not
“seeing“ the speakers. Speakers were connected
after the software was started. Some configurations require that audio
and MIDI devices are connected prior
to starting any software applications
with which you may wish to use the
devices. Try restarting the application
with the speakers plugged in and
powered on.
