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 effect on the performance of the subwoofer, so time and effort 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. YUMI, YU3, SYD6), power
or integrated amplifi ers with preamplifi er output (e.g. YARO), or multi-channel home theater
receivers with subwoofer output. If your components are equipped with both L/R subwoofer
outputs or L/R preamplifi 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-off frequency of your main speakers.
The Phase Switch is normally set to 0°. If the sub8 is positioned signifi cantly farther from the
main speakers or if the subwoofer is used in a stereo setup where the amplifi 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
difference, 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.
