Safety information

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

Warning

To reduce the risk of electric shock, do not remove the cover or back. No user serviceable parts inside. Refer servicing to qualified service personnel.

To reduce the risk of fire or electric shock, do not expose your speakers to rain or moisture. Dangerous high voltages are present inside the enclosure.

Do not open the cabinet.

Caution

To prevent electric shock, match the wide blade on the power cord plug to the wide slot on an electric outlet. If the plug does not fit, consult a licensed electrician to replace the obsolete outlet. Do not modify the power cord plug, or you will defeat this safety feature.

When replacing the direct plug-in power supply or a separable, cord-connected power supply, the replacement must be an exact duplicate or one which has been recommended by the manufacturer.

This symbol indicates that there is dangerous voltage within the enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

This symbol indicates that there are important operating and maintenance instructions in the literature accompanying your speakers.

Important safety instructions

1Read these instructions.

2Heed all warnings.

3Follow all instructions.

4Do not use your speakers near water.

5Clean only with a dry cloth.

6Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

7Do not defeat the safety purpose of the polarized or grounding-type 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 the 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.

8Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from your speakers.

9Only use attachments or accessories specified by the manufacturer.

10Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer.

11 Unplug your speakers during lightning storms or when unused for long periods of time.

12 Refer all servicing to qualified service personnel.

13 Servicing is required when your speakers have been damaged in any way, such as the power supply cord or plug is damaged, liquid has been spilled or objects have fallen into your speakers, your speakers have been exposed to rain or moisture, do not operate normally, or have been dropped.

14 Your speakers should not be exposed to dripping or splashing, and no objects filled with liquids, such as vases, should be placed on your them.

15 The main power switch is used as the disconnect device, so the switch should always remain within easy reach for quick shutoff. The standby switch does not disconnect the speaker system from power.

The double insulation symbol indicates a double-insulated product. In a double-insulated product, two systems of insulation are provided instead of grounding.

Auto signal switch

This three-position switch controls the power status of

the subwoofer.

• Off: Turns the subwoofer off.

• Auto: Places the subwoofer in standby mode. In

standby, the subwoofer automatically turns on

when an audio signal is applied to either the high

(speaker) level or low (line) level inputs. In this

mode, the subwoofer will turn off about

15 minutes after the input signal has stopped.

• On: Turns the subwoofer on regardless of

whether a signal is present.

	#			Component				Description
	4			Line level input				These RCA jacks accept a line-level, full-range signal
								from the pre-amplifier or LFE output of a receiver or
								preamplifier.
								This full-range signal is processed and amplified to
								power the subwoofer.
	5			Polarity switch				This two-position switch allows the best match of
								acoustic output between the subwoofer and the
								satellite speakers in the crossover frequency region
								between them.
								• The 0° position maintains phase from input to
								output.
								• The 180° position changes the polarity by 180°.
								Try both settings and pick the one that sounds best.
	6			Status LED				This shows the status of the subwoofer.
								• Red indicates that the amplifier is plugged in and
								the power switch is either off or in standby mode
								with no input signal present.
								• Green indicates that the amplifier is operating
								with a signal present at the input from the
								pre-amplifier, receiver, or power amplifier.
	7			Subwoofer				This rotary control sets the upper frequency at which
				crossover				the output of the subwoofer begins to roll off.
				(frequency)				Continuously variable from 60 Hz to 160 Hz, it
								matches the upper frequency characteristics of the
								subwoofer to the low-frequency response of the
								satellite speakers.
								Recommended setting: 150 Hz.
	8			Volume control				This rotary control adjusts the level of the subwoofer
				(gain)				and is used to balance its volume with that of the
								satellite speakers.
	9			Main power switch				This switch controls the overall power status of the
								subwoofer. It must be in the ON position for the
								subwoofer to operate.
	10			Fuse				For continued protection, replace the fuse with the
								same type and size listed.

Setting up your speakers

Positioning your speakers

The following illustration depicts the most generally accepted speaker locations for a home theater system.

	Center front
Left front	Right front

Subwoofer

45

	Listening area
Left	Right
rear	rear

Although there are limitless ways you can arrange your speakers, using the above illustration as a template will provide a great starting point. Experiment with slightly different speaker locations for improved performance in your specific listening environment.

The left front and right front speakers should form a 45-degree triangle, using the center seating position as the apex.

The rear speakers should be placed beside the listening area, and pointed towards each other, about 2-3 feet above the listener’s head.

Front speaker heights

One of the most important parameters for the front speakers in a home theater system is their height. Refer to the following illustration for an example of ideal speaker height placement.

In an ideal arrangement, all three speakers are aligned on the same horizontal plane in relation to the viewing screen. This establishes a firm “audio image” height when special audio effects are panned from one side to the other, such as a speeding car moving across the screen.

Proper placement

A large “audio image” discontinuity (mismatch) occurs when the heights of the front speakers vary, as illustrated below. This uneven speaker arrangement makes the “audio image” of a moving object sound unnatural due to shifts in the audio image height.

Improper placement

Refer to the following illustration as a guide for connecting speakers using line-level (subwoofer) inputs from A/V amplifiers and receivers with 5.1-channel outputs.

Connect the subwoofer LFE output of a receiver to either the left or right line-level RCA input jack. In this situation, a Y adapter could be used but is not required. If you don’t have an LFE output, then left/ right pre-amplifier outputs can be connected to the left/right line-level RCA input jacks.

Care and maintenance

Use the following guidelines to maintain the appearance of your speakers:

•Use a soft, damp cloth to clean the speaker cabinet.

•Avoid using harsh detergents or cleaning fluids.

•Remove the grilles to vacuum and remove dust.

•Do not vacuum any of the speaker components, because permanent damage could result.
