Introduction
Thank you for choosing the sub8 sealed powered subwoofer. sub8 was designed to
augment the bass performance of your speakers in a stereo setup or in a home theater
installation.
Adding a subwoofer to your system extends the bass response produced by your
existing speakers and improves their midrange clarity. In a home theater application, the
subwoofer takes care of reproducing signals from the low frequency eects channel. In
a stereo system, the subwoofer helps reduce the low-frequency demands on the main
speakers.
We recommend you read all instructions carefully before using the sub8 and keep them
for future reference. Kanto cannot be liable for damage or injury caused by incorrect
setup or use of this product.
This powered subwoofer was carefully tested and inspected during production, and
before packaging and shipping. After unpacking, please check for any damage. It is
rare that a unit is damaged during shipping, but if this happens contact your retailer
immediately. You can also contact Kanto directly:

Setting Up and Connecting your Subwoofer
Ensure that the ON/OFF Switch is in the OFF position before connecting any component.
To some degree, positioning the subwoofer is less critical because it produces only non-
directional low-frequency sounds. However, best results are obtained if the subwoofer
is placed either between the left and right speakers or in the vicinity of either the left
channel or right channel speaker.
As with all speakers, moving the sub8 very close to room boundaries will enhance
the bass frequencies but will tend to muddy the sound. Room characteristics and
positioning have a profound eect on the performance of the subwoofer, so time and
eort devoted to achieving the optimum operating position will be rewarded.
In a typical full range application using one subwoofer like the sub8 thru a single wire
connection, you can connect to either the Left or Right Line Level Input. Connect your
stereo component such as powered speakers with subwoofer output (e.g. YU, YU2, YU4,
YU6), power or integrated ampliers with preamplier output , or multi-channel home
theater receivers with subwoofer output. If your components are equipped with both
L/R subwoofer outputs or L/R preamplier outputs, we recommend connecting the
component to the sub8 by using both Left and Right Line Level Input channels.
The Low-Pass Filter Control is used to set the upper limit of the frequencies that sub8
will reproduce, typically within the range of 40Hz-120Hz. Refer to your manufacturer’s
information for the cut-o frequency of your main speakers.
The Phase Switch is normally set to 0°. If the sub8 is positioned signicantly farther from
the main speakers or if the subwoofer is used in a stereo setup where the amplier
driving the main speakers inverts the phase signal, the 180° setting may be desirable.
Listen with the switch in both positions and select the setting that gives the fullest
sound. If in doubt, or if there is little dierence, leave the switch set to 0°.
Follow the instructions on the following page to connect your components to sub8. The
examples are not meant to be exhaustive - just examples.
ATTENTION
When connecting audio cables the ON/OFF Switch must be turned OFF. After connecting all cables, the unit can be
turned ON.

Audio Troubleshooting Guide
Frequently asked questions about Kanto’s sub8.
• Ensure the power cable is connected to the
subwoofer and power outlet.
• Ensure that the power outlet is providing power.
• Verify that the power switch on the rear of the
subwoofer is in the “On” position.
• Check the fuse on the rear panel of the subwoofer to
ensure it’s intact. • Check that the RCA cable connected to and from the
subwoofer is rmly seated. Try a dierent cable or
source to isolate the issue.
• Make sure the subwoofer is connected to a power
outlet and is set to “On” or “Auto”.
• Increase the volume of the subwoofer.
• Ensure audio source is playing audio.
• Check that the audio cable connected to the source
is rmly connected. Test another audio cable if
available.
• Verify that the volume of the subwoofer is not at it’s
minimum level.
• Ensure you are using an RCA to RCA subwoofer
cable.
• Verify if the noise is coming from the source by
removing the source from the subwoofer.
• Make sure it is not a power issue by trying a power
outlet that is on a dierent circuit.
• Check that the audio cable connected to and from
the source is rmly seated. Try a dierent cable or
source to isolate the issue.
• Set the source of the volume to a higher level and
reduce the volume of the subwoofer. Low source
volume can negatively aect dynamic range.
• Test a dierent song or source to isolate the issue.
• Adjust crossover to match the rest of the system.
