FEATURES

Your Optimus System 745 Stereo Rack System is a versatile sound system combining a 100 watt-per-channel amplifier with Dolby Pro Logic Surround Sound, precision AM/FM stereo receiver, dual-dubbing cassette deck, 24-disc automatic CD changer, and front, center, and rear speakers.

The 100-watt, thr ee-way front speakers combine 10-inch woofers, 4-inch midranges, and 3-inch tweeters to give you exc ell ent respo ns e in al l fr equency ranges. The efficient bassreflex design provides a cleaner sound than acoustic suspension speakers.

The 15-Watt, full range center and surround speakers’ simulated black wood-grain veneer cabinets finish make the speakers attractive, and the cabinet design enhances the bass response.

PREPARATION

Cautions:

• Do not connect the system to AC power until you complete all other connections.

• Be sure to follow all the instructions in the enclosed “Safety Instructions” sheet.

UNPACKING THE SYSTEM

The protective cardboard sheet in the system’s CD com partment helps protect the system from damage during shipment or while moving it. To remove the cardboard sheet, first remove all packing material from around the system, then press When the CD changer’s door opens, remove the cardboard sheet, then close the door.

Note:

case you ever want to move the system to another area. Before y ou mo ve the system, be sure there are no CDs in the CD changer, then re-insert the cardboard sheet into the CD changer’s center slot.

The system speakers’ features and specifications are packed with the speakers.

Save the cardboard sheet in

PLACING THE SPEAKERS

The System 745 includes one center, two front, and two rear (surround) speakers. Before you connect them, follow these steps t o place the speakers.

Front Speaker

1. Place the center speaker directly in front of the listening area, above or below the TV.

Note:

netically shielded to prevent vid eo distortion. However, if the TV picture has interference, increase the distance between the TV and t he speaker, but keep the speaker in line with the TV.

Center Speaker

Rear Speakers

The center speaker is mag-

Front Speaker

13-129 3.fm Page 9 Wednesday, Ju ly 14, 1999 6: 49 PM

2. For the best stereo effect, place the front speakers on each s ide of the center speaker so:

• the distance between each

speaker and the center speaker is the same

• the distance between the

speakers is the same as the distance between the listening area and the center speaker

Notes:

• To improve the stereo effect if

the distance between the speakers is greater than the distance between the listening area and the center speaker, angle the speakers in toward you.

• To increase the bass effect,

place the front speakers in the corners of the room, against the wall, or directly on the floor.

• To decrease the bass effect,

move the front speakers slightly away from the corners or raise them 6 to 8 inches off the floor. Your local RadioShack store carries speaker stands.

3. Place the surround speakers to the rear and sides of the listening area.

CONNECTING THE SPEAKERS

For the best results, connect the two front speakers to the

ERS

terminals, the center speaker to

CENTER SPEAKER

the the two rear speakers to the

ROUND SPEAKERS

back of the system.

Important:

• If you are using speakers other than the ones supplied, remember that each speaker connected to the system’s speaker terminals must have an impedance of at least 8 ohms. Your local RadioShack store has a large selection of speakers.

• For maximum bass response and best overall performance, connect your speakers so their pol arities match (+ to +, and – to –).

CONNECTING THE ANTENNAS

You can use the supplied indoor AM loop antenna and FM dipo le antenna for adequate reception in most areas.

Connecting an FM Antenna

The supplied FM antenna is usually adequate for FM reception in metropolitan areas. If FM reception is weak, we recommend you use an outdoor antenna for improved rece ption. Your local RadioShack store sells outdoor antennas and accessories.

To connect an FM antenna, hold down both

EXTERNAL ANTENNA FM 300Ω

terminal tabs, insert the stripped ends of the FM a ntenna’s wires into the terminal’s holes, then release the tabs.

Fully extend and position the FM antenna for the best reception.

Note:

na, follow all the ins t ru ct ions in the enclosed “Safety Instructions” sheet and the warnings included with the a ntenna. Use 300-ohm twin lead wire for this connection.

Warnin

you install or remove an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches the power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to r emove it yourself.

If you install an outdoor a nten-

PUTTING BATTERIES IN THE REMOTE CONTROL

The system’s remote control requires two AA batteries (not s up plied) for operation. For the longest life and best performance, we recomme nd alkaline batteries, such as RadioShack Cat. No. 23-557.

1. Remove the battery compartment cover by pressing down the top of the cover while sliding it away from the remote control.

2. Insert two fresh AA batteries in the compartment as indicated by the polarity symbols (+ and –) ma rked inside the compartment.

Cautions:

• Dispose of batteries promptly and properly; do not bury or burn them.

• Never leave dead or weak batteries in the rem ot e control.

CONNECTING HEADPHONES

You can connect a pair of headphones to t he System 7 45 to l isten in private. Your local RadioShack store has a wide selection of headphones.

To connect headphones to the system, put the hea dphones’ into the

PHONES

jack on the system.

/4-inch plug

Cautions:

• Use only fresh batteries of the required size and type.

• Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

3. Replace the cover.

If the remote control does not work or has poor range, replace both batteries.

Note:

automatically disconnects the external speakers. If you are using the surround mode, however, connecting t he headphones does not disconnect the center and rear speakers.

Connecting the headphones

13-129 3.fm Page 14 Wednesday, J uly 14, 1999 6: 49 PM

Listening Safely

To protect your hearing, follow these guidelines when you use headphones.

• Set the volume to the lowes t setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

• Do not listen at extremely high volume levels. Extended highvolume l istening can l ead to permanent hearing loss.

• Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that d oes not cause discomfort might still damage your hearing.

CONNECTING POWER

After you make all other connections, plug the system’s power cord into a standard AC outlet. The red STA NDBY indicator lights when the system i s connected to AC power but the system is turned off.

RESETTING THE SYSTEM

M-ERROR

If play, or the system does not work properly when CD is selected, make sure the protective cardboard sheet has been removed. After removing the cardboard, if the system still does not work properly, you might need to reset it.

Note:

DOLBY PRO LOGIC SURROUND

Dolby Surround is a process that makes movies more exciting by c reating a more realistic audio experien ce to accompany the action on the screen. Rather than all the sound coming from the front of the theater (or your living room), the sound seems to surround you, making you feel like you are closer to the action.

The Pro Logic technology makes home theater sounds more realistic. The Pro Logic decoder separates the audio according to the apparent location of the source. You hear dialogue from the center speaker, normal stereo background sound from the left and right front speakers, and enhanced surround sound from the rear speakers.

In addition, many television stations broadcast regular programs with Dolby Surround. Also, most satellite programs, especially movies, are broadcast with Dolby Surround.

The System 745 gives you the best sound performance from music sources that have the logo.

Selecting the Dolby S urround Mode

When playing a program source encoded with Dolby Surround Sound, follow these steps t o sel ect the proper surround mode.

1. Repeatedly press

MODE

until the desired Dolby Pro Logic Surround mode (PRO LOGIC or 3-CH L OGIC) indicator lights.

SURROUND

Dolby Surround Encoded Material

Program sources such as laser discs, video tapes, and cable broadcast s are usually direct copies of the original motion picture’s sound track. All these sources have surround sound audio if the original soun d track had it. Many video tapes and laser discs are marked with the logo. However, many that are not marked also have su rround sound audio.

• Select PRO LOGIC when using

front, center, and rear speakers.

• Select 3-CH LOGIC when using

only front and center spea kers. The sound that w ould normally come from the surround (rear) speakers is routed to a nd combined with the sound that comes from the left and right front speakers.

13-129 3.fm Page 18 Wednesday, J uly 14, 1999 6: 49 PM

• Select OFF (so neither indicator lights) when using stereo headphones, playing a monaural program, or receiving a weak FM broadcast (the soun d quality might improve).

2. If you selected PRO LOGIC and you connected the supplied front, center, and rear speakers, then repeatedly press

CENTER MODE

until the WIDE indicator lights.

If you selected PRO LOGIC and you connected speakers other than the ones supplied, repeatedly press

CENTER MODE

to select one of the following operating modes:

NORMAL

Select this mode when

using a center speaker with limited low-frequency response . The low-frequency sounds present at the center of the screen are routed equally to the front left and right speakers. This creates the illusion that the sound is coming from the center.

WIDE

Select this mode when

using a full-range center speaker that has good low-frequency response. The low-frequency sounds present at the center of the screen are routed to the center speaker.

PHANTOM

Select this mode when

not using a center speaker. The sound present at the center of the screen is routed equally to the left and right front speakers. This creates the illusion that th e sound is coming from the center.

3. Press

MEMORY TUNING

You can automatically or manually store up to 36 stations (AM o r FM) in the system’s memory.

Note:

The tuner keeps the st ored stations even when you turn off the system or unplug it from the AC outlet.

Automatically Storing Stations

You can set up the system so it automatically stores FM and AM stations. During auto store, the system first scans the FM band and automatically stores the first 24 strong FM stations it finds into memory locations 1–24.

Then the system scans the AM band and stores the first 12 strong AM stations it finds into memory locations 25–36.

Follow these steps to set up the system so it automatically stores FM and AM stations.

ASSIGNING CATEGOR Y AND SUBCATEGORY NAMES TO LOADED CDS

You can assign a category name to each loaded CD, and then use category names to select and play only those CDs that contain the type of music you want to hear.

In addition to assigning category names, you can further define music styles within the same category by assigning your own subcategory name to the CD.

For example, if you load two jazz CDs and assign a JAZZ category name, you can assign subcategory names such as DIXIE or FUSION. You must assign a category to a loaded CD b efore you can assign a subcategory to it.

CD CARE TIPS

Even though a CD is very durable, you should handle it with care.

• Keep the CD inside the CD changer or in its protective case or sleeve when you are not playing it.

• Handle a CD by its edges to avoid fingerprints which can prevent the CD changer’s laser beam from accurately reading the CD. Your local RadioShack store sells a suitable CD cleaner kit.

• Do not write on either s ide of the CD, particularly the non-label side. (Signals are read from the non-label side.)

• Keep the CD dry. A water drop can act as a lens and affect the laser beam’s focus.

• If a CD skips or the CD changer displays try to play it, the CD might be scratched. Your local RadioShack store sells a Scratch ’n Fix kit (Cat. No. 42-127) that might help remove the scratch and stop the skip (see “Troubleshooting” on Page 46).

TAPE TIPS

Storing Cassettes

Do not store cassette t apes in places with high temperature or high humidity or where large amou nts of dust or dirt exist.

Preventing Accidental Erasure

Cassettes have two erase-protection tabs, one for each recording side.

To protect a recording from bein g accidentally recorded over or erased, use a screwdriver to remove one or both tabs.

Side A Tab

Caution:

tion tab does not prevent a bulk tape eraser from erasing a cassette.

Removing the erase-protec-

Erasing a Cassette Tape

To erase a cassette tape, select an audio source with no audio playing, then simply record as usual. The cassette deck records silence over the previous recording.

You can quickly erase both sides of a cassette tape using a bulk tape eraser such as Cat. No. 44-232, available at your local RadioShack store.

Resto r ing Tape Tension and Sound Quality

After you play a cassette tape several times, the tape might become tightly wound on the reels. This can cause playback sound quality to deteriorate.

If you want to record on a cassette that has had its tab removed, put a piece of heavy plastic tape over the recording tab hole.

Be sure you cover only the hol e originally covered by the erase-protection tab.

To restore the sound quality, fastforward the tape from the beginning to the end of one side, then completely rewind it. Then loosen the tape reels by gently tapping each side of the cassette’s outer shell on a flat surface.

Caution:

the cassette when tapping it. Do not touch the exposed tape or allow any sharp objects near the cassette.

Be careful not to damage

CARE AND MAINTENANCE

Your Optimus System 745 Stereo Rack System is an example of superior design and craftsmanship. The following sugges tions will help you care for the system s o you can enjoy it for years.

Keep the system dry. If it gets wet, wipe it dry imm ediately. Liquids can contain minerals that can corrode the electronic circuits.

Use and store the system only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries in the remote c ontrol, and distort or melt plastic parts.

Keep the system away from dust and dirt, which can cause premature wear of parts.

Handle the system gently and carefully. Dropping it can dam age circuit boards and cases, and can cause the system to work improperly.

Use only fresh batteries of the required size and type in the remote control. Always remove o ld o r weak batteries. They can lea k c hem icals that destroy electronic circuits.

Wipe the system with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the system.

Caution:

cleaner. The vacuum action can permanently damage speaker elements. Modifying or tampering with the system’s internal parts can caus e a malfunction

and might invalidate your system’s warranty and void your FCC authorization to operate it. If your system is not working as it should, take it to your local RadioShack store for assistance.

Gently clean the speakers with a feather dus ter. Do not use a vacuum

13-129 3.fm Page 49 Wednesday, J uly 14, 1999 6: 49 PM

CLEANING THE TAPEHANDLING PARTS

Dirt, dust or particles of the tape’s coating can accumulate on the tape heads and other parts that the tape touches. This can greatly reduce the cassette player’s performance. To prevent noise and poor high-frequency response, clean the cassette player’s tape-handling parts after every 20 hours of use. Your local RadioShack store sells a complete line of cassette deck cleaning supplies.

Follow these steps to clean the tapehandling parts on your system’s cassette decks.

1. Turn off the system, then unplug its power cord.

Note:

745 clears the CD changer ’s programmed sequence memory but does not clear stations in mem ory or category/subcategory names.

2. Press sette decks. Both cassette compartment doors open.

3. Press decks to expose the tape-handling parts.
