SW-15

POWERED SUBWOOFER

-INTRODUCTION-

The Motion Sound SW-15 subwoofer is specifically designed to complement the sound of “on
stage” keyboard amplifiers and up to 500 watt PA systems. The front panel controls and inputs
are easily accessible providing “on stage” style adjustment and operation.

Although operation may seem intuitive, we suggest that you read this manual for helpful tips
and/or details about controls and operation of the SW-15 in various venues and environments.

4. Set volumes at “0”, high cut at 150, 45 and 60 Hz at zero, phase switches at +.

5. Play intended low notes and increase SW-15 volume to desired level.

6. Switch, phase switch for loudest bass sound.

-SOUND-

-WHAT TO EXPECT-

Always try to place the SW-15 on the floor, this enhances the cabinet size and lower bass sound.
Bass is very difficult to product in small rooms and/or low ceilings because of wavelength null
points. You will hear different bass levels depending on the notes played and your relative
position to the SW-15 and the room surfaces. Also consider the sound your audience will hear,
solicit the help of a knowledgeable friend to listen with you when setting phase switches and
adjusting EQ. Keep in mind moving the SW-15 even a few inches can make a difference.

-INPUTS-GENERAL-

Both the XLR and the ¼ TRS inputs are balanced inputs to help eliminate ground loops and
associated “hum”: (Do not route input wires close to transformers (SW-15 left rear) or heavy
power lines).

If your equipment has balanced outputs use them. If it does not it still may help to use a three
conductor balanced type cord in the TRS input to reduce hum;

-TRS Input: This tip/ring/sleave input is balanced with a phase switch and volume control.
Tip=plus Ring=neutral Sleave=ground
