1. Before you do the connection, make sure that you have prepared a dedicated subwoofer cable to
support your bass system.
2. Found the place of “subwoofer output” at the rear of your receiver and the place of “SUB IN” at
your subwoofer amplifier board, insert the subwoofer cable from the receiver’s “subwoofer output” to
subwoofer’s “SUB IN”.
3. We recommend to use a “shielded subwoofer cable” to avoid annoying signal into your bass
performance.
4. Found the place of “Power Connector” at your subwoofer amplifier board. Plug the AC power cord
into the back of your subwoofer and then into a wall outlet or power strip. DO NOT plug it into the back of
your receiver or preamp.
5. V12SW is sold with a wireless receiver. If you want to use wireless function, insert the TX transmitter
into the receiver’s “subwoofer output” instead of subwoofer cables.
Properly place the subwoofer will improve the bass performance greatly and deliver even sound pressure
level throughout your listening area. Here are a few guidelines to help finding the optimal location.
1.If you use one V12SW subwoofer, you can place it within one foot of the corner to get a greatest output
level.
2. If you use a pair of V12SW subwoofers, measure the width between two sides of your room, place
them at 1/3 and 2/3 of the room.
3.Different from 5.0 system, the placement rule of subwoofer is much flexible than 5.0 system since it is a
non directional sound unit. Use the golden rule to perform a few experiments to find a best location in the
room until your ears are satisfied with the results.

“LFE + Main” if your front speakers are “small”; if your front speakers are “large”, then
set up the subwoofer value to “LFE”
