Clean only with dry cloth.6.

Do not block any ventilation openings. Install in accordance with the 7.

manufacturer’s instructions.

Do not install near any heat sources such as radiators, heat registers, 8.

stoves, or other apparatus (including ampliﬁers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding-type 9.

plug. A polarized plug has two blades with one wider than the other.

A grounding-type plug has two blades and a third grounding prong.

The wide blade or third prong is provided for your safety. If the

provided plug does not ﬁt into your outlet, consult an electrician for

replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched, particularly

at the plugs, convenience receptacles and the point where they exit

from the apparatus.

11. Only use attachments/accessories speciﬁed by the manufacturer.

12. Use only with the cart, stand, tripod, bracket or table

speciﬁed by the manufacturer or sold with the apparatus.

When a cart is used, use caution when moving the cart/

apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when

unused for long periods of time.

14. Refer all servicing to qualiﬁed service personnel. Servicing is required

when the apparatus has been damaged in any way, such as: when

the power supply cord or plug has become damaged, when liquid has

been spilled or objects have fallen into the apparatus, when the appa-

ratus has been exposed to rain or moisture, when the apparatus does

not operate normally, or the apparatus has been dropped.

15. Do not expose this apparatus to dripping or splashing and ensure

that no objects ﬁlled with liquids, such as vases, are placed on the

apparatus.

16. To completely disconnect this apparatus from the AC mains, discon-

nect the power supply cord plug from the AC receptacle.

17. The mains plug of the power supply cord shall remain readily operable.

18. Do not expose batteries to excessive heat such as sunshine, ﬁre or the

like.

The lightning ﬂash with arrowhead symbol, within an equilateral

triangle, is intended to alert the user to the presence of uninsulated

“dangerous voltage” within the product’s enclosure that may be of

sufﬁcient magnitude to constitute a risk of electric shock to

persons.

The exclamation point within an equilateral triangle is intended to

alert the user to the presence of important operating and mainte-

nance (servicing) instructions in the literature accompanying the

product.

WARNING: To reduce the risk of ﬁre or electric shock, do not expose this

apparatus to rain or moisture.

IMPORTANT: The subwoofer requires proper ventilation and is not to be

used in an enclosed environment.

usIng the suPPlIed sPIkes

Four metal spikes are supplied for use when you place the subwoofer on a

carpeted surface. Using the spikes decouples the subwoofer from the ﬂoor

and prevents unwanted acoustic damping.

TO INseRT The sPIkes:

1. Gently turn the subwoofer upside down on a soft, nonabrasive surface.

2. Unscrew and remove the rubber bumpers from the subwoofer’s feet.

3. Screw each spike into the threaded insert in each foot. Make sure all

four spikes are screwed in completely for stability.

NOTe: NEVER drag the subwoofer to move it, as this will damage the

spikes, the feet and/or the subwoofer cabinet itself. Always lift the sub-

woofer and carry it to its new location.

suBWooFer rear-Panel controls and connectIons

Phase switch: This switch determines whether the subwoofer driver’s

piston-like action moves in and out in phase with the system’s other

speakers. If the subwoofer were to play out of phase with the other speak-

ers, the sound waves from the other speakers could partially cancel out

the sound waves from the subwoofer, reducing bass performance and

sonic impact. This phenomenon depends in part on the placement of all

the speakers relative to each other in the room.

Input Mode switch: When this switch is in the “Normal” setting, the input

signal from the Line In connectors is active. When this switch is in the

“LFE” setting, the input signal from the LFE In connector is active, and the

subwoofer’s internal crossover is bypassed.

Level control: Use this control to adjust the subwoofer’s volume. Turn the

knob clockwise to increase the volume; turn the knob counterclockwise to

decrease the volume.

Crossover control: This control determines the highest frequency

at which the subwoofer reproduces sounds. The higher you set the

Crossover control, the higher in frequency the subwoofer will operate and

the more its bass will “overlap” that of the system’s other speakers. This

adjustment helps achieve a smooth transition of bass frequencies between

the subwoofer and the other speakers for a variety of different rooms and

subwoofer locations. The Crossover control functions only when NOTE:

the Input Mode switch is in the “Normal” position. When the switch is

in the “LFE” position the subwoofer’s built-in crossover and Crossover

control are bypassed.

On/Standby indicator: This LED indicates whether the subwoofer is in

the On or Standby state:

• When the LED glows green, the subwoofer is turned on.

• When the LED glows red, the subwoofer is in the Standby mode.

• When the LED is off, the subwoofer’s Power switch is set to “Off.”

Line In connectors: The signals from these connectors pass through

the subwoofer’s internal low-pass crossover. When you’re connecting the

subwoofer to the preamp or subwoofer outputs of a receiver/processor

that does not have its own low-pass crossover network, use both Line In

connectors. You must also set the Input Mode switch in IMPORTANT:

the “Normal” position. If your receiver/processor has only one subwoofer

output, you can use either the L or R connector.

LFE In connector: The signal from this connector bypasses the subwoof-

er’s internal low-pass crossover. When you’re connecting the subwoofer

to the dedicated subwoofer output of a receiver/processor that has its own

low-pass crossover network, use the LFE In connector. IMPORTANT: You

must also set the subwoofer’s Input Mode switch in the “LFE” position.

Power switch: Set this switch in the “On” position to put the subwoofer in

the Standby mode (the On/Standby LED lights red); set this switch in the

“Off” position to turn the subwoofer off.

Power Cord connector: After you have made and veriﬁed all subwoofer

connections described in this manual, plug the power cord into an ac-

tive, unswitched electrical outlet for proper operation of the subwoofer.

DO NOT plug this cord into the accessory outlet found on some audio

components.
