MK Sound VX-1250 - Manual (Page 8)

If your amplifier has two sets of speaker outputs (e.g., A and B), you can connect the satellites to one set and the
subwoofer to the other. But if you get weak or no output when you connect your speaker this way, connect both sets of
speaker wires to the same output terminals.
PLUGGING IN THE SUBWOOFER
Once all the speaker wires or preamp interconnect cables are in place, you are ready to plug in the subwoofer. Set
the "BASS LEVEL" control to "MIN". Attach the power cord to the receptacle on the subwoofer’s back panel. Then plug
the cord into the AC outlet.
Slide the power switch to either the “AUTO” or “ON” position. If your hear a “thump” from the subwoofer, this is the
normal sound of its power supply charging.
“AUTO” SWITCH POSITION
In the “AUTO” switch position, the subwoofer is in an idle condition when your system is turned off and no signal is
being fed to the subwoofer. When the subwoofer receives a signal from your receiver or processor, it automatically
switches on.
“ON” SWITCH POSITION
In the “ON” switch position, the subwoofer is fully active, whether or not your other components are turned on.
Do not plug the subwoofer into a switched outlet on another component.
Now, play some music through your system to make sure that the satellite speakers are working properly. If they
are, carefully advance the "BASS LEVEL" control. The subwoofer should begin to play. Set the "BASS LEVEL" control
where the subwoofer sounds in balance with the satellite speakers. If the system is not working properly, unplug the
subwoofer and check all of your connections. Call your dealer or the factory if you cannot solve any problem.
6. USE OF THE “PHASE” CONTROL
Your subwoofer has a phase control that allows for continuous adjustment between 0˚and 180˚ degrees. This con-
trol let you fine tune the transition between the subwoofer and your other speakers.
To optimize the sound of your new subwoofer, you need to perform a Phase Test. This test insures optimum sound
in the critical bass frequencies where your subwoofer and Satellite speakers overlap.
