Volume Adjustment

• If the system is connected to the YST-MSW5’s LINE OUT jack as shown in System
example 1 on page 1, set the YST-MSW5’s BASS control to the noon or one-o’clock
position and raise the volume control of the powered main speakers to the maximum.
Then, use the YST-MSW5’s VOLUME control to adjust the overall volume.

• If the YST-MSW5 is connected to an output jack for a sub-woofer on a powered main
speaker (such as a Yamaha YST-M15, YST-M7, etc.) as shown in System example 2 on
page 1, raise the VOLUME control of the YST-MSW5 to the maximum and set the
BASS control to the noon or one-o’clock position. Then, use the volume control of the
powered main speakers to adjust the overall volume.

Réglage du volume

• Si le système est branché à la borne LINE OUT du YST-MSW5 comme indiqué dans
l’exemple de connexion 1 de la page 1, réglez la commande BASS du YST-MSW5 en
position “midi” ou “13h” et réglez la commande de volume des enceintes actives sur le
niveau maximum. Servez-vous ensuite de la commande VOLUME du YST -MSW5 pour
ajuster le volume global.

• Si le YST-MSW5 est branché à une sortie pour subwoofer d’une enceinte active (telle
qu’un Yamaha YST-M15, YST-M7, etc.) comme indiqué dans l’exemple de connexion 2
de la page 1, réglez la commande VOLUME du YST-MSW5 au maximum et placez la
commande BASS en position “midi” ou “13h”. Utilisez ensuite la commande de volume
des enceintes actives pour ajuster le volume global.

Einstellen der Lautstärke

• Wenn das System mit der LINE OUT-Buchse der YST-MSW5 verbunden ist (siehe
Systembeispiel 1 auf Seite 1), müssen Sie den BASS-Regler der YST-MSW5 in die 12­oder 1-Uhr-Position und die Lautstärke der Hauptlautsprecher auf den Höchtswert stel­len. Anschließend können Sie die allgemeine Lautstärke mit dem VOLUME-Regler der
YST-MSW5 einstellen.

• Wenn Sie die YST-MSW5 mit dem Tieftöner-Ausgang eines aktiven Hauptlautspre­chers (z.B. einen Yamaha YST-M15, YST-M17 usw.; siehe Systembeispiel 2 auf Seite

1), müssen Sie den VOLUME-Regler der YST-MSW5 auf den Höchstwert und den
BASS-Regler in die 12- oder 1-Uhr-Position stellen. Anschließend können Sie die allge­meine Lautstärke mit dem VOLUME-Regler des Hauptlautsprechers einstellen.

Volymreglering

• När systemet anslutits till linjeutgången LINE OUT på YST-MSW5 enligt systemexem­pel 1 på sidan 1: ställ volymreglaget BASS på YST-MSW5 i ett läge motsvarande
klockan tolv eller ett och volymreglaget på högtalarna med inbyggd förstärkare i läget
för maximal volymnivå. Använd därefter volymreglaget VOLUME på YST-MSW5 till
att reglera den sammanlagda volymen.

• När YST-MSW5 anslutits till en lågbashögtalarutgång på en huvudhögtalare med
inbyggd förstärkare (t.ex. Yamahas YST-M15, YST-M7, etc.) enligt systemexempel 2 på
sidan 1: ställ volymreglaget VOLUME på YST-MSW5 i läget för maximal volymnivå
och volymreglaget BASS i ett läge motsvarande klockan tolv eller ett. Använd därefter
volymreglaget på högtalarna med inbyggd förstärkare till att reglera den sammanlagda
volymen.

Regolazione del volume

• Se il sistema è collegato alla presa LINE OUT dello YST-MSW5 com o mostrato
nell'Esempio di sistema 1 a pagina 1, regolare il comando BASS dello YST-MSW5
sulla posizione corrispondente alle 12 o 1 di un'orologio e alzare al massimo il comando
del volume dei diffusori principali amplificati. Quindi usare il comando V OLUME dello
YST-MSW5 per controllare il livello globale del volume.

• Se lo YST-MSW5 è collegato ad una presa di uscita per subwoofer di un diffusore prin­cipale amplificato (come lo YST-M15, YST-M7, ecc. Yamaha) come mostrato
nell'Esempio di sistema 2 a pagina 1, alzare al massimo il comando VOLUME dello
YST-MSW5 e regolare il comando BASS sulla poszione corrispondente alle 12 o 1 di
un orologio. Quindi usare il comando del volume dei diffusori principali amplificati per
regolare il livello globale del volume.

Ajuste del volumen

• Si el sistema está conectado a la toma LINE OUT del YST-MSW5, como se muestra en
Ejemplo del sistema 1 de la página 1, ajuste el control BASS del YST-MSW5 a la posi­ción de las doce o la una en punto, y aumente al máximo el nivel del control de volumen
de los altavoces principales con altavoz incorporado. Después, utilice el control
VOLUME del YST-MSE5 para ajustar el volumen global.

• Si el YST-MSW5 está conectado a una toma de salida para un altavoz de subgraves de
un altavoz principal con altavoz incorporado (como el YST-M15, YST-M7, etc.
Y amaha), como se muestra en Ejemplo del sistema 2 de la página 1, aumente al máximo
el nivel del control V OLUME del YST-MSW5 y ajuste el control BASS a la posición de
las doce o la una en punto. Después, utilice el control de volumen de los altavoces prin­cipales con amplificador incorporado para ajustar el volumen global.

Instellen van de geluidssterkte

• Als u een stel luidsprekers aansluit op de LINE OUT aansluiting van de YST-MSW5,
zoals aangegeven in Voorbeeld 1 op blz. 1, dan zet u de BASS regelaar van de YST­MSW5 in de middenboven-stand of iets daar voorbij (twaalf of één uur op de klok) en
draait u de volumeregelaar van de aangesloten luidsprekers met ingebouwde versterker
in de maximumstand. Vervolgens gebruikt u de VOLUME regelaar van de YST-MSW5
om de totale geluidssterkte naar wens in te stellen.

• Als u de YST -MSW5 aansluit op de lagetonen-uitg angsaansluiting v an een stel hoofdluid­sprekers met ingebouwde versterker (zoals de Y amaha YST-M15, YST -M7 e.d.) zoals aan­gegeven in Voorbeeld 2 op blz. 1, dan draait u de VOLUME regelaar van de YST-MSW5
in de maximumstand en zet u de BASS regelaar middenbo ven of iets daar voorbij (twaalf
of één uur op de klok). Vervolgens gebruikt u de volumere gelaar v an de hoofdluidsprekers
met ingebouwde versterker om de totale geluidssterkte naar wens in te stellen.

Thank you for purchasing Yamaha’s YST-MSW5 Powered Multimedia Subwoofer. Yamaha’s Active Servo Technol­ogy offers exceptionally high performance.

Cautions

Please read the following operating precautions before
use:

• When disconnecting the AC power cord from an AC
receptacle, hold and pull the plug, not the power cord.

• If the YST-MSW5 is not going to be used for a while,
disconnect the AC power cord from the AC receptacle.

• Always disconnect the AC power cord from the AC
receptacle before making any connections.

• The YST-MSW5 does not contain any user serviceable
parts. Refer all servicing to your Yamaha dealer.

Never open the cabinet. If a foreign object drops into

•
the set, contact your dealer, and do not use the
YST-MSW5. Otherwise, you may cause a fire.

• Do not expose the YST-MSW5 to temperature extremes,
direct sunlight, excessive dust, humidity, or vibration.

• Position the YST-MSW5 on a level, stable surface. Do
not drop the YST-MSW5, apply excessive force to
their controls, or put heavy items on top of them.

• Since this unit has a built-in power amplifier , heat will
radiate from the rear panel. Therefore, place the unit
apart from the walls, allowing a space of at least 10 cm
(3-15/16") above, behind and on the both sides of the
unit. Also, do not position with the rear panel facing
down on the floor or other surface.

• Do not obstruct the port with your hand or a foreign
object.

• T o protect the YST -MSW5 speak er, avoid microphone
feedback, continuous and excessive output from elec­tronic musical instruments, and excessive signal dis­tortion.

• If the YST-MSW5 is located close to fluorescent or
neon lights, a slight hum may be heard. In this case,
relocate the YST-MSW5 away from the light.

• Although the YST-MSW5 speaker is magnetically
shielded, keep floppy disks and tapes away from them.

• The YST-MSW5 may cause picture distortion when
located close to a television or computer monitor. In
this case, move them away a short distance.

• Avoid sources of hum (transformers, motors). To pre­vent fire or electrical shock, do not expose to rain and
water.

• Do not use force on switches, knobs or cords. When
moving the YST-MSW5, first turn the YST-MSW5 off.

• Always turn the volume control counterclockwise
before starting to play the audio source: increase the
volume gradually to an appropriate level after the play­back has started.

CAUTION

The apparatus is not disconnected from the AC
power source as long as it is connected to the wall
outlet, even if the apparatus itself is turned off.

CAUTION (FOR CANADA MODEL): TO PREVENT
ELECTRIC SHOCK, MATCH WIDE BLADE OF
PLUG TO WIDE SLOT AND FULLY INSERT.

This prevents small speakers from becoming over­loaded.
