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.

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.

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 kHz-Speaker 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 (S hown 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
about five seconds so this leader tape is past the heads.
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.
