connected to a power supply only of the type described

in the operating instructions or as marked on the

appliance.

11. Grounding or Polarization – Precautions should be

taken so that the grounding or polarization means of

an appliance is not defeated.

12. Power-Cord Protection – Power-supply cords

should be routed so that they are not likely to be walked

on or pinched by items placed upon or against them,

paying particular attention to cords at plugs,

NOTE:

To CATV system installer’s (U.S.A.): This reminder is provided to call the CATV system installer’s attention to

Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected as close to the point of cable entry as practical.

CAUTION: Read this before operating your unit

CAUTION

The apparatus is not disconnected from the AC power source so long as it is connected to the wall outlet, even if the apparatus itself is turned off. To fully insure that the apparatus is indeed fully void if residual power, leave unit disconnected from the AC outlet for at least fifteen seconds.

1. To ensure the finest performance, please read this manual carefully. Keep it in a safe place for future

reference.

2. Install your unit in a cool, dry, clean place – away from windows, heat sources, and too much vibration,

dust, moisture or cold. Avoid sources of hum (transformers, motors). To prevent fire or electrical shock, do

not expose to rain and water.

3. Do not operate the unit upside-down.

4. Never open the cabinet. If a foreign object drops into the set, contact your dealer.

5. Place the unit in a location with adequate air circulation. Do not interfere with its proper ventilation; this will

cause the internal temperature to rise and may result in a failure.

6. Do not use force on switches, knobs or cords. When moving the unit, first turn the unit off. Then gently

disconnect the power plug and the cords connecting to other equipment. Never pull the cord itself.

7. Do not attempt to clean the unit with chemical solvents: this might damage the finish. Use a clean,

dry cloth.

8. Be sure to read the “Troubleshooting” section on common operating errors before concluding that your unit

is faulty.

9. This unit consumes a fair amount of power even when the power switch is turned off. We recommend that

you unplug the power cord from the wall outlet if the unit is not going to be used for a long time. This will

save electricity and help prevent fire hazards. To disconnect the cord, pull it out by grasping the plug.

Never pull the cord itself.

10. To prevent lightning damage, pull out the power cord and remove the antenna cable during an electrical

storm.

11. The general digital signals may interfere with other equipment such as tuners or receivers. Move the

system farther away from such equipment if interference is observed.

12. When positioning your equipment, especially regarding speakers or other accessories, avoid positioning

them over areas where they can fall and cause injury to yourself and others.

Listening For A Lifetime

Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Association’s

Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level

• Start your volume control at a low setting.

• Slowly increase the sound until you can hear it comfortably and clearly, and without

distortion.

Once you have established a comfortable sound level

• Set the dial and leave it there.

• Pay attention to the different levels in various recordings.

Taking a minute to do this now will help to prevent hearing damage or loss in the future.

After all, we want you listening for a lifetime.

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.

Some common decibel ranges:

Level Example

Before Getting Started:

Things to Consider

It is very important to read the following instructions prior to starting any installation procedures. Doing so will ensure a correct installation and may save you some time as well.

Protect Against Power Surges

• Connect all external components before you plug any of their power cords into the

wall outlet.

• Turn off the DUET-II before you connect or disconnect any cables.

• Make sure all cables are properly grounded.

Protect Components from Overheating

• Don’t block ventilation holes. Arrange any components so that air can circulate freely.

• Don’t stack components.

• If you place the DUET-II on a stand, make sure you allow adequate ventilation.

Position Cables Properly to Avoid Audio Interference

• Insert each cable firmly into the designated jack.

• If you place components above the DUET-II, route all cables down the side of the

back of the DUET-II instead of straight down the middle of the back of the

DUET-II.

Important Stand and Base Safety Information

Choose the location for your DUET-II carefully. If the DUET-II is placed on a stand or base, ensure that it is of adequate size and strength to prevent it from being accidentally tipped over, pushed off, or pulled off. This could cause personal injury and/or damage to the

DUET-II.

Preparations

• This unit is designed to play CD’s bearing the COMPACT DISC identification logo. If any CDs do not bear

the COMPACT DISC logo, they may not play properly.

• Fingerprints and dust should be carefully wiped off with a soft cloth. Wipe in a straight motion from the center

to the outside of the disc.

• Never use chemicals such as record cleaning sprays, anti-static sprays or fluids, benzene or thinner to clean

compact disc. These chemicals will permanently damage the plastic surface of the disc.

• Always place the compact disc on the disc tray with the label facing upward. Compact discs can be played

on only one side.

• To remove a disc from its storage case, press down the center of the case and lift the disc out holding it

carefully by the edges.

• Discs should be returned to their cases after use to protect them from dust and scratches.

• To prevent warping the disc, do not expose it to direct sunlight, high humidity, or high temperatures for

extended periods of time.

• Do not apply paper or write anything on either side of the disc. Sharp writing instruments, or the inks used in

some felt-pens, may damage the surfaces of the disc.

Audio Controls

Graphic EQ Settings

After choosing the program source you want; adjust the GRAPHIC EQUALIZER controls as follows:

1. Adjust the VOLUME control for the desired listening level.

2. Set the GRAPHIC EQUALIZER controls to match the sound characteristics of your listening room. With

each of the five controls of the GRAPHIC EQUALIZER, it is possible to control a narrow, distinct section of

the audio band by up to +/-10dB. The frequency bands controlled by the slide controls have been chosen to

give you the best possible control action within the audio spectrum.

100 Hz Is very useful for enhancing low bass notes (as in organ music, kick drum, etc.) or making corrections when a deficiency in bass exists. Or you can use this to reduce rumble, acoustic feed back, and other low frequency aberrations.

300 Hz Will allow you to vary the upper bass frequencies. An over-accentuated, upper bass will give a muddy, boom quality to music while the system shy of upper bass will sound hollow and thin.

1 kHz Lies in range of frequencies where the ear is most sensitive to tonal balance. This is often called

“presence”, since adjusting this control brings the vocalist out to the front or back into ensemble.

3. 3 kHzSpeaker designers often boost output in this range to effect a quality of presence to the music. Too

much energy on the other hand, sounds overbearingly harsh and stringent.

10 kHz Adjustment affects the brilliance of music with too much boosts in high frequencies (can be an unpleasant and piercing quality). You may use this to add a little more dimension to the high-shelf sound or use it as a very high frequency noise filter.

Using Your Radio

AM or FM - Press the POWER button ON. Slide the FUNCTION SELECTOR to AM or FM. Rotate the tuning knob to the desired listening station.

Cassette Handling

Operating Tips

1. High quality tapes will give you better recordings and more listening pleasure. Tapes of the following types

are suggested: Low noise, high density, high output or extended range with a play or record time up to 90

minutes.

NOTE: Cassette with a time of 120 minutes (C120) are not recommended because they contain

thinner and longer tapes which are more likely to jam or tangle in the player/recorder.

2. For best results in playing or recording, it is necessary for the head to be clean. Refer to cleaning

instructions. Keep cassettes away from excessive heat or cold.

(Fig. 1)

3. If the tape is loose in the cassette, tighten it before putting it in.

To do so, put a pencil into the hub and turn it to the right (Shown in Fig. 1)

4. A leader tape begins each side of a cassette. You cannot play or

record on this part of the tape. You have to let the tape run for

a b o u t f i v e s e c o n d s s o t h i s l e a d e r t a p e i s p a s t t h e h e a d s .

NOTE: When you start the tape, be sure the tape take–up reel is moving.

If the reel is not moving stop the machine at once; if you don’t the tape could become tangled in the

player/recorder. If this does happen, carefully remove the cassette and correct it as shown above.

Cassette Tape / Deck Maintenance

Erase Protection

Every cassette can be protected against accidental erasing of pre-recorded material. On the back of a cassette are two breakout tabs. These must be in place before the RECORD button will depress. If these tabs have been removed, such as on pre-recorded cassette you buy, the RECORD button will not depress. To record using a cassette which has the breakout tabs removed, place a piece of tape over the exposed holes, this will allow the interlocking device to engage

Far Side 1(A)

Near Side 2(B)

Break tab

Once you have made a recording, you can prevent an accidental erasing by breaking out and removing the tabs. With side 1(A) facing you, erasing is prevented by breaking out the tab on the right, and side 2(B) by the tab on the left (see drawing).

Cleaning

To prevent fire or shock hazard, disconnect your stereo system from the AC power plug when cleaning.

• The finish on our stereo may be cleaned with a dust cloth and cared for as other furniture. Be careful when

cleaning and wiping the plastic parts. Mild cleaners, such as dishwashing detergent, with dampened (not

wet) cloth may be used on the front panel.

Tape Deck Cleaning

• To get the best sound from your tapes, the pressure roller, capstan, play/record and erase heads should be

cleaned regularly. The build up of iron oxide particles is often severe with inferior tapes and will reduce the

performance or the system. After every 100 hours of use, or more often if playback has become poor, clean

the play/record and erase heads, capstan and pressure roller. To clean them, wipe dry with a soft, clean

cloth.
