Yamaha NS-E105 Руководство пользователя

  • Привет! Я прочитал инструкцию по эксплуатации для акустических систем Yamaha NS-E105. Я могу ответить на ваши вопросы о подключении, технических характеристиках, особенностях использования и мерах предосторожности. Например, я знаю, как правильно подключить колонки, как избежать обратной связи и как ухаживать за ними.
  • Как правильно подключить колонки к усилителю?
    Что делать, если слышны искажения звука?
    Можно ли чистить колонки химическими растворителями?
    Как избежать обратной связи?
    Можно ли монтировать колонки на стену?
Thank you for selecting this Yamaha NS-E105
speaker system.
This model is designed to be used as an effect
speaker
in a Cinema DSP/Surround Sound system.
Note
Do not let the bare speaker wires touch each
other as this could damage the speaker and/or
the amplifier.
PRECAUTIONS
Read these precautions carefully before using your
speaker.
Any time you note distortion, reduce the volume
control on your amplifier to a lower setting. Never
allow your amplifier to be driven into “clipping”.
Otherwise the speaker may be damaged.
When using an amplifier with a rated output power
higher than the nominal input power of the speaker,
care should be taken never to exceed the speaker’s
maximum input.
Do not attempt to clean the speaker with chemical
solvents as this might damage the finish. To clean,
wipe with a dry, soft cloth.
To prevent the enclosure from warping or discolor-
ing, do not place the speaker where it will be
exposed to direct sunlight or excessive humidity.
Do not place the speaker where it is liable to be
knocked over or struck by falling objects. Stable
placement will also ensure better sound perfor-
mance.
Placing the speaker on the same shelf or rack as
the turntable can result in feedback.
As these speakers contain strong magnets, avoid
placing watches, magnetic tapes, etc. near them.
Also, placing the speakers near a TV set may impair
picture color. If this happens, move the TV set away
from the speakers.
Secure placement or installation is the owner’s
responsibility. YAMAHA shall not be liable for
any accident caused by improper placement or
installation of the speaker.
CONNECTION TO
YOUR AMPLIFIER
BEFORE MAKING CONNECTIONS, MAKE SURE
THAT THE AMPLIFIER IS SWITCHED OFF.
CONNECTIONS
Connect the push-type input terminals at the rear of
the speakers to the speaker output terminals of
your amplifier with the provided speaker cables.
One side of the speaker cable is marked by a blue
line. Connect the (+) terminals on both the amplifier
and the speakers using this blue-marked side.
Connect the (–) terminals on both components
using the unmarked side of the cable.
Connect one speaker to the left (marked L) termi-
nals of your amplifier, and another speaker to the
right (marked R) terminals, making sure not to
reverse the polarity (+, –). If one speaker is con-
nected with reversed polarity, the sound will be
unnatural and lack bass.
Procedures:
Press the tab on the terminal down, as shown in
the figure.
Insert the bare wire end properly into the terminal
hole. [Remove approx. 5 mm (1/4”) insulation
from the speaker cable.
Remove your finger from the tab to allow it to lock
snugly on the cable’s wire end.
Test the security of the connection by tugging
lightly on the cable at the terminal.

The holes on the speaker’s back panels are arranged
so that the speakers can be mounted in either of the
two configurations shown by the following figures.
Upright configuration
Side long configuration
Setting the speakers on a shelf or rack
As shown in the figure, the speakers may be stood in
a vertical or horizontal configuration on a shelf or a
rack, by putting a supplied stand into a hole on the
back of each speaker.
WARNING:
* Each speaker weighs 2 kg (4 lbs. 7 oz.). Do not
mount them on thin plywood or soft wall surface
material, as the screws may come out of the flimsy
surface, causing the speakers to fall down and be
damaged, or result in personal injury.
* Do not fasten the speakers to walls with nails, adhe-
sives, or other unsound hardware. Long-term use
and vibrations may cause them to fall down.
* To avoid accidents resulting from tripping over loose
speaker cables, fix them to the wall.

SETTING UP THE SPEAKERS
Mounting the speakers on a wall
The speakers may be mounted on a wall by using the
holes provided on the speakers’ back panels. Fasten
wood screws into a firm wall or wall support as shown
in the diagram, and hang the holes on the protruding
screws.
Make sure that the screw is caught by a narrow part
of the hole securely.
