1. TRIGGER: For external power triggering, use a mini (3.5 mm) mono plug to connect the IN

jack to a power on/off trigger signal from a home theater surround sound processor or

other voltage. Source power on is 3 to 30 Vdc (or Vac). Power off is 0 Vdc (or Vac). Use

the OUT jack to pass the TRIGGER signal (at the same voltage level of the trigger input)

to another LSS-10 and LSS-12 or other equipment in your system. THIS JACK SHOULD

NOT BE USED TO POWER OTHER EQUIPMENT.

NOTE: For a system not equipped with a power trigger output, consider using a 12-volt

power supply as a trigger signal that is activated via a switched AC outlet on the receiver.

2. (Auto) POWER Switch: Use the ALWAYS ON mode to leave the LSS-10 and LSS-12 always

on. Use the MUSIC/VOLTAGE SENSE mode to automatically power on the LSS-10 and

LSS-12 when audio signals are present or when system trigger is used. When signals are

absent, the LSS-10 and LSS-12 will enter the standby mode.

NOTE: The ALWAYS ON and MUSIC/VOLTAGE SENSE settings are only active after (Master)

POWER is set to ON (see below).

3. AUDIO IN jacks: Use these gold-plated, line-level RCA input jacks to connect line-level

stereo or LFE audio signals from a home theater surround sound processor or receiver.

The LFE (Low Frequency Effects) input is not affected by the LOW PASS Frequency

Control. The PHASE Control and LEVEL Control continue to function as normally expected.

4. AUDIO OUT jacks: Use these gold-plated, line-level RCA output jacks to connect

line-level stereo or LFE audio signals to drive another LSS-10 or LSS-12 or loop your line

level audio signal back to your surround sound processor or receiver. (The L/R output

signals are routed through a fixed HIGH-PASS (80 Hz) filter).

5. SPEAKER IN Binding Posts: As an alternative to the AUDIO IN jacks, use the loudspeaker-

level, gold-plated, five-way binding posts to connect loudspeaker-level, stereo audio

signals from a home theater surround sound processor or receiver. For additional

connection details, see Finishing the Installation on page 5.

6. SPEAKER OUT Binding Posts: As an alternative to the AUDIO OUT jacks, use the

loudspeaker-level, gold-plated, five-way binding posts to connect loudspeaker-level,

stereo audio signals to drive your front L/R satellite loudspeakers.

7. (Master) POWER Switch: Use this control to power on/off the LSS-10 and LSS-12.

8. Detachable IEC Power Cord and built-in fuse. If needed, replace the fuse with same type,

as follows:

■ For 115/120 Vac @ 60 Hz, use a T5AL, 250V fast-blow fuse.

■ For 230/240 Vac @ 50 Hz, use a T3.15AL, 250V fast-blow fuse.

FINISHINGTHE INSTALLATION

Adjusting the Feet

2. Connect the other end of the

loudspeaker wires to the home theater

receiver (or amplifier) and satellite

loudspeakers in the same way.

The LSS-10 and LSS-12 are equipped with

four adjustable spiked feet, pre-installed

with large, slip-on rubber covers. At the final

placement location, adjust the feet/spikes

as follows:

3. Using the five-way binding post of

the LSS-10 and LSS-12, connect the

loudspeaker outputs to the appropriate

satellite loudspeaker in the same way.

■ On hard floors (e.g., wood, tile, etc.),

check the LSS-10 and LSS-12’s stability

and, if needed, adjust the rubber feet one

at a time until the cabinet is level.

4. Turn on the home theater receiver and

calibrate all loudspeakers in the system

according to the receiver (processor)

manufacturer’s instructions.

■ On carpeted floors, tilt the LSS-10 and

LSS-12 up and remove each rubber

cover. Check the LSS-10 and LSS-12’s

stability and, if needed, adjust the spikes

one at a time until the cabinet is level.

Setting Up the LSS-10 and

LSS-12

After making all the connections and

calibrating the loudspeakers, set up

the LSS-10 and LSS-12 by performing

the following steps (see Controls and

Connectors on page 4 for information on

control operation):

Connecting the LSS-10 and

LSS-12

Connect the LSS-10 and LSS-12 according

to your application (see APPLICATIONS on

page 7). Use high-quality RCA cables for all

line-level connections (see CONTROLS AND

CONNECTORS on page 4). For applications

with loudspeaker-level connections,

perform the following steps:

1. On the rear panel, set the (Auto) POWER

switch to ALWAYS ON or MUSIC/

VOLTAGE SENSE. Depending on your

application.

2. On the front panel, set the following

controls (and switches) to their initial

positions:

1. At each LSS-10 and LSS-12 loudspeaker-

level connection, separate the

■ LEVEL control = 5

loudspeaker wire so that at least 2

inches of each conductor are free. Strip

away 1/4 inch of insulation from each

loudspeaker wire. Using correct polarity,

connect the appropriate conductor

to each five-way, speaker level, input

binding post.

■ LOW PASS FREQUENCY control

= 120 Hz

■ PHASE control = 0°

3. While playing a favorite music track,

adjust your system’s volume control to a

comfortable level and listen to the bass

level at your favorite listening position

(e.g., couch).

NOTE: Observe correct polarity: Positive (+)

goes to the RED post and negative (–) goes

to the BLACK post.

DS00490ACN-0 LSS-10_12.indd

5/23/06

2:12:59 PM

4. Continue listening to your favorite

music and movie sources. If you want

a more solid-sounding bass (with less

overtones), try moving the LOW PASS

FREQUENCY control toward the lower

frequencies. Experiment with different

frequency settings until you find one

that sounds best. If needed, readjust the

LEVEL control (see step 3).

A pair of out-of-phase loudspeakers works

against each other, and the sound of the

two playing together will be lacking in bass

and sound “phasey.” If you suspect the

sound is not right, and you cannot see any

markings on the wire, try this simple test:

1. Stand halfway between the satellite

loudspeakers.

2. Play some music with the amplifier or

receiver set to Mono.

5. Continue listening to your favorite

music and movie sources using the

appropriate setting for LEVEL SETUP.

Try experimenting with the PHASE

control until you find its optimum setting.

Depending on the LSS-10 and LSS-12

placement, the bass should sound more

pronounced when the phase has been

optimized.

3. Listen to the richness of the bass and the

loudness of the sound.

4. Turn off the amplifier and reverse the

connections on the LSS-10 and LSS-12

SPEAKER OUT binding post.

5. Repeat the listening test with the same

volume control setting. When the sound

has a richer bass and is slightly louder,

the satellite loudspeakers are working

together or “in-phase.”

Checking Phase on the

Satellite Loudspeakers

Loudspeaker wire has two conductors. On

applications with satellite loudspeakers,

one conductor is attached to a component’s

negative (–) terminal, while the other is

attached to a component’s positive (+)

terminal. Usually, the wire is marked for your

convenience, but the marking can be done

in the following different ways:

Installing and Removing the

Grille

■ To install the grille, start with the top two

grille posts and gently press the grille

frame in at each of the five recessed

holes. When properly installed, the grille

will be approximately 2 to 3 mm away

■ Stripe on one wire

from the cabinet along the sides.

■ Ribbed area you can feel on one

conductor

■ To remove the grille, start with the bottom

grille posts and gently pull the grille frame

away from the LSS-10 and LSS-12’s edge

at each of the five recessed holes. Store

the grille in a safe place for future use.

■ Different colors of metal wire on each

conductor

■ Fabric strand or string wound into one of

the conductors

Cleaning

Use a dampened soft cloth or paper towel

to clean the cabinet and grille.

Of course, there are some wires that appear

completely identical. If wired incorrectly,

one satellite loudspeaker will be playing

“out-of-phase” with the other loudspeaker.
