Congratulations on your purchase of an Elura

Black Label Series SUBB8.2/SUBB10.2 powered subwoofer. It will give your stereo, or home theater system unparalleled low frequency output.

Bass frequencies are critical to realistic sound reproduction. After you’ve hooked up your SUBB8.2/SUBB10.2 subwoofer, you’ll discover just how much “punch” and depth you’ve been missing. No matter what kind of music or videos you listen to... whether you listen to it loud or soft, you’ll experience sound that’s richer and fuller. Bass guitar and string bass will have more impact. You’ll be able to FEEL as well as hear percussion – just the way you would at a live performance. If you have an audio/video system, movies will come alive with thunderous sound effects that were never possible without the Elura SUBB8.2/SUBB10.2.

The Elura SUBB8.2/SUBB10.2 is a self-powered subwoofer that frees your receiver or power amplifier from the power demands of reproducing very low frequencies. To do this, the Elura SUBB8.2/SUBB10.2 incorporates its own built-in crossover system that automatically “assigns” lower frequencies to its own power amplifier, contained within the subwoofer enclosure.

The Elura SUBB8.2/SUBB10.2 has been meticulously designed and tested to insure high performance, durability and longevity.

This manual is designed to take you step-by-step through the hook-up and operating process. This procedure is not difficult, but it IS slightly different than hooking up a line level component such as a cassette deck or DVD player. Reading this manual carefully will insure that you get maximum performance from your Elura SUBB8.2/SUBB10.2.

A. UNPACKING

Remove the Elura SUBB8.2/SUBB10.2 from its packing carefully and inspect it for any shipping damage. If you discover damage, contact your Elura dealer or installer immediately.

If possible, save the carton and internal packing. It’s the best possible protection for your Elura SUBB8.2/SUBB10.2 if you need to move it or return it for service.

Keep your sales receipt in a secure place. It helps establish the duration of your warranty and is good for insurance purposes (just in case anything happens to your stereo/home theater system).

B. AMPLIFIER

PANEL TOUR

Before actual hookup, you should familiarize yourself with the connections on the back of the Elura SUBB8.2/SUBB10.2, as shown in Fig.1.

1. POWER INDICATOR:

OFF = No color STANDBY = Red ON = Blue.

2. LFE/SUBWOOFER/ LOW LEVEL LINE IN (line level connections). These connections are

used if you have a preamplifier or a receiver/integrated amplifier which has LFE, subwoofer, or line level outputs that follow the volume control, or to connect to the line-level audio output of a flat panel TV.

3. VOLUME CONTROL. Rotating this knob clockwise increases the output level of the subwoofer. To start out, make sure that the VOLUME is turned all the way down (fully counterclockwise). Later, after some initial listening tests, you can adjust the volume to your own taste. However, care should be taken not to overdrive the subwoofer to the point of audible distortion.

4. CROSSOVER FREQUENCY CONTROL. This control determines what lower part of the frequency spectrum will be reproduced by the Elura SUBB8.2/SUBB10.2. It is a “crossover” control. Rotating the knob sets the point where all lower frequencies will be handled by the subwoofer.

As a starting point, set the control around 100Hz if you are using left and right tower speakers, 125 - 150Hz. with bookshelf or small mini-speakers.

5. PHASE SWITCH. This switch is used to set the subwoofer’s phase between normal “0°” or reverse “180°” (out of phase). Once you determine the placement of the Elura SUBB8.2/ SUBB10.2, you will need to set this switch for the best bass output for your listening position. The physical location of your subwoofer and main speakers determines the phase setting that will sound best at your main listening position.

6. OFF/AUTO/ ON SWITCH. This switch turns Elura SUBB8.2/SUBB10.2 on or into AUTO mode. When this switch is in the AUTO position, the amplifier will stay turned on as long as a signal is being fed to the subwoofer amplifier. Approximately 8 minutes after you stop playing music or a video, the amplifier goes into STANDBY mode. When you again begin to play music or a video, the amplifier will automatically turn on. With the switch in the ON mode the amplifier will stay on indefinitely.

7. NON-REMOVABLE AC POWER CORD.

C. PLACEMENT

Where to position your Elura SUBB8.2/SUBB10.2

The Elura SUBB8.2/SUBB10.2 operates at low bass frequencies which are essentially omni-directional. That means you can place the Elura SUBB8.2/ SUBB10.2 almost anywhere in a room without compromising the effectiveness of your main stereo speakers.

Four factors need to be considered:

1) distance from your main speakers;

2) distance from a wall outlet;

3) distance from your receiver, amplifier,

or flat panel TV; and

4) proximity to walls and corners.

5) CAUTION: The Elura SUBB8.2/SUBB10.2 are

not magnetically-shielded. If used with an older CRT monitor or TV, keep it at least 2 feet from the monitor.

1. Distance from your main speakers. The best placement for your subwoofer is on the same wall as the main speakers, especially if you are matching up with small bookshelf speakers. With tower speakers, side wall or rear placement is also acceptable.

2. Wall outlet. Since the Elura subwoofer requires AC power, it must be placed where it will reach a wall outlet. We don’t recommend extending that range with an extension cord.

3. Connections to your receiver, amplifier, preamplifier or flat panel TV. You will need to con-

nect the subwoofer to your receiver subwoofer output or LFE output, flat panel TV, or preamp line level outputs (see next page). You can basically place the Elura SUBB8.2/SUBB10.2 anywhere in a normal-sized room.

4. Proximity to walls and corners. Physical placement of the subwoofer will have a definite impact on the frequency response and the perceived amount of Elura SUBB8.2/SUBB10.2 bass output. Because low frequencies have long wavelengths, they are influenced by proximity to a boundary such as a wall or floor.

See Fig. 2. When you place the Elura SUBB8.2/ SUBB10.2 well away from a wall, it will produce bass at a certain level. Move the subwoofer close to the wall, it will produce more output (about 3dB more). Putting the subwoofer in a corner will increase output another 3dB (6dB more than when placed away from walls and corners).

All this technical jargon may sound confusing, but it basically means that you have a number of options, each of which produces a different amount of bass. For example, if you like a lot of heavy bass, consider putting the Elura SUBB8.2/SUBB10.2 into a corner. If you like smoother, less-obvious bass, move the subwoofer out into the room. The main thing to remember is that there is no “right” or “wrong” place to put the Elura SUBB8.2/SUBB10.2. It all depends on how much bass you want.

Another reason to experiment – because low bass waves are very large (up to 40 feet or more across!), they tend to cancel and reinforce each other, causing places in the room where there is lots of bass and others where there isn’t very much at all. If you walk around your listening room while playing music, you’ll probably discover these sorts of areas where bass is either exaggerated or reduced. Needless to say, if your main listening area ends up in a “dead” space, you will need to move the Elura SUBB8.2/SUBB10.2 so that bass is more normal.

Incidentally, moving the Elura SUBB8.2/SUBB10.2 around won’t affect the stereo imaging of your main stereo system, so feel free to try various subwoofer positions.

Away from walls:

Normal bass

Against walls:

More bass

Connecting to a wall plug

The Elura SUBB8.2/SUBB10.2 draws a moderately high amount of current. We do not recommend plugging it into a “convenience” outlet (switched or unswitched) that is often found on the back of receivers and other stereo components.

Instead, connect the subwoofer ONLY to its own AC outlet. See items 9 and 10 in the Safety Instructions on Page 2 of this manual.

D. CONNECTIONS

Three basic connection options

1. Connection to electronics with subwoofer or LFE output. If you own a surround sound

receiver or integrated amplifier with a subwoofer or LFE output, use Method A as shown in Fig. 3.

2. Connection to stereo preamp and amplifier. If you have separate preamp and amplifier, use Method B as shown in Fig. 4.

3. Connection to flat-panel TV. If you have a flat panel TV with stereo analog audio outputs,

use Method C as shown in Fig. 5.

(Refer to Fig. 3)

Note: This connection method is only for receivers that

have a subwoofer or LFE output. You will need one line level RCA to RCA connector cable long enough to reach from your receiver to your Elura SUBB8.2/SUBB10.2 location. This should be available from your Elura dealer or from radio supply stores.

1. IMPORTANT: Make sure that ALL system components including the Elura SUBB8.2/SUBB10.2 are turned OFF before proceeding.

2. Locate the subwoofer or LFE output connector on the

rear of your receiver and connect one end of the RCA line level cord to it.

3. Route the line cord to the subwoofer location (trying to minimize areas where it may be stepped on) and connect the other end directly to the sub’s LINE IN R or LFE input.

(Refer to Fig. 4)

1. IMPORTANT: Make sure that ALL system components including the Elura SUBB8.2/ SUBB10.2 are turned OFF before proceeding.

2. Locate the LINE output RCA sockets on the back of your

preamplifier. These are typically marked PRE, PRE OUT, LINE OUT or TO POWER AMP, depending on the make and model of component.

3. Connect a set of high-quality line level RCA male to dual female Y-connectors to the preamp’s LINE OUT sockets. Then connect a pair of high-quality line level cables from the Y connectors to the left and right LINE IN of your subwoofer. Make sure that left is connected to left and right is connected to right.

4. Connect another set of connection cables between Y-connectors and the MAIN INPUTS of your power amplifier. Again, make sure that left is connected to left and right is connected to right.

5. Connect your main speakers to the speaker terminals on the back of your power amplifier.

6. You are now ready to put your Elura SUBB8.2/SUBB10.2 subwoofer into use. Skip to “E – INITIAL LISTENING TEST.”

(Refer to Fig. 5 below)

1. IMPORTANT: Make sure that ALL system components including the Elura SUBB8.2/SUBB10.2 are turned OFF before proceeding.

2. Connect a set of high-quality line level connection cables (patch

cords) between the TV analog audio output connectors and the LINE IN sockets on the back of the Elura SUBB8.2/SUBB10.2. Make sure that left is connected to left and right is connected to right.

3. You are now ready to put your Elura SUBB8.2/SUBB10.2 subwoofer into use. Skip to “E – INITIAL LISTENING TEST.”

E. INITIAL LISTENING TEST

It’s now time to introduce the Elura SUBB8.2/SUBB10.2 amplifier’s potent and plentiful bass into your listening environment.

1. Double-check all connections.

. Make sure that the volume controls on both the Elura SUBB8.2/SUBB10.2

nd your receiver/integrated amp/preamp/TV are turned all the way down (fully

ounterclockwise). Set the PHASE switch to zero. Set the CROSS- OVER FRE-

c QUENCY knob to 100Hz for normal operation, or to 150Hz for Dolby Digital operation where the proper crossover frequency is set in the receiver’s crossover.

3. Turn on your stereo/home theater system. THEN turn on the Elura SUBB8.2/ SUBB10.2. Confirm that the subwoofer’s blue POWER indicator is glowing. If it isn’t, check the power connections between the Elura SUBB8.2/SUBB10.2 and the wall socket.

4. Play a musical selection or DVD that you are familiar with. Pick a song that has regular low bass beats. Advance the receiver/ integrated amp/preamp/TV’s volume control up to a normal listening level. If you don’t hear sound through your main speakers, turn off the system and check connections. Also consult the troubleshooting tips on page 8.

5. If sound is indeed coming out of your main speakers, turn the Elura SUBB8.2/SUBB10.2’s VOLUME control clockwise until you hear noticeable additional bass. If you don’t hear bass by the time you have advanced the subwoofer’s VOLUME control halfway, turn off the system and check connections. Also consult the troubleshooting tips on page 8.

FIG.5 – Method C, Line Level Hook-up with Flat Panel TV

6. Adjust the Elura SUBB8.2/SUBB10.2’s VOLUME control until you are satisfied

with the amount of bass. You may want to try several different albums, compact discs, or DVDs while determining how high to adjust the Elura SUBB8.2/ SUBB10.2’s VOLUME. The amount of bass varies from CD to CD and DVDs.

7. Now that you have adjusted the quantity of bass via the volume, it’s time to work on the quality of the bass with the CROSSOVER FREQUENCY control, PHASE switch – and experimentation with Elura SUBB8.2/SUBB10.2 room position.

• While playing music or a movie, move the subwoofer around, in and out of corners, closer and farther from the wall, etc. as much as the power cord and other connections will allow.

• Change the PHASE switch between 0° - 180°, while someone sits in the main listening position. Leave the switch in the position where you like the bass most.

• Change the CROSSOVER FREQUENCY control (for Dolby Pro-Logic receivers) to higher and lower settings. If the CROSS-OVER FREQUENCY control is set too high, you’ll start to hear low midrange (voices and instruments) through it. This will negatively affect the stereo imaging of your main speakers. Lower the CROSSOVER FREQUENCY setting until you hear only bass from the Elura SUBB8.2/ SUBB10.2. If the CROSSOVER FREQUENCY control is set too low, you simply won’t get much output from the subwoofer. Move it back closer to 80 - 100Hz.

8. After you are satisfied with the output of your Elura SUBB8.2/SUBB10.2, you can make all your volume settings through your main stereo system’s volume control. The only time you might want to re-adjust the Elura SUBB8.2/SUBB10.2’s VOLUME is when you encounter a musical selection or movie that has abnormally low – or high – bass.

You can leave the Elura SUBB8.2/SUBB10.2 turned on and in AUTO mode when not in use. It does not draw much power in this state and will be ready to add low bass the moment you begin to play music.

Remember, you don’t have to do anything except leave the POWER switch in the AUTO position. The Elura SUBB8.2/SUBB10.2 will automatically go into STANDBY mode after approximately 8 minutes, when no music or movie is playing.

If you’re not using your system for a long period of time (such as when you’re on vacation), turn the POWER switch to the OFF position.

G. TROUBLESHOOTING

& SERVICE

Before returning your Elura SUBB8.2/SUBB10.2 for service, you can save time (and often embarrassment) by checking for a few problems that are most often encountered.

Power light is not lit. No sound.

1. Is your Elura SUBB8.2/SUBB10.2 plugged in

to a live AC wall socket?

2. Is the power switch on?

3. Has the Elura SUBB8.2/SUBB10.2 overheated

and shut off temporarily?

No sound from either set of speakers.

1. Are your other components turned on?

2. Is the receiver, preamp, or TV set to the appro-

priate input and is that sound source playing?

3. Do you have an unconnected tape monitor selected?

4. Is the Elura SUBB8.2/SUBB10.2 correctly connected to your receiver, preamplifier, integrated amplifier, or TV and turned on?

Sound comes from main speakers but not the subwoofer

1. Is the Elura SUBB8.2/SUBB10.2 turned on

(power light in the blue mode) and VOLUME control turned up?

2. Some digital receivers only send a sub out signal when in the movie or digital mode. In the 2 channel (stereo music) mode, no sub out signal is sent to the sub.

You may need to set your main speakers to “small” mode in your receiver setup to get the receiver’s subwoofer output to turn on. Check your receiver’s owner’s manual for subwoofer operation.

3. For digital receivers – make sure the subwoofer is “ON” and the subwoofer level is set to “0 dB” or greater.

Sound comes from the subwoofer but not your main speakers

1. • Confirm that the power amplifier is turned on.

• Check the RCA patch cord

• Check the speaker wire connections between the receiver and main or satellite speakers.

Bass is muffled or weak

1. Check speaker wire polarity of all connections.

2. Reposition your subwoofer. At some points in

the room, its output may be cancelled by the geometry of the room. Moving the Elura SUBB8.2/SUBB10.2 can eliminate this problem. Please refer to Item 14 in the Safety Instructions for conditions that ALWAYS require service by qualified personnel.

If you have tried all the above and still can’t get the Elura SUBB8.2/SUBB10.2 to operate properly, consult your dealer or contact MSTR BRAND.
