FOIRE AUX QUESTIONS - TU3W BOSS

Comment allumer le Boss TU-3W ?

Branchez votre instrument à la prise INPUT. La pédale s'allume automatiquement. Pour activer l'accordeur, appuyez sur le pied de la pédale ; le voyant CHECK s'allume.

Comment accorder une guitare en accordage standard ?

Sélectionnez le mode GUITAR en appuyant sur le bouton MODE. Jouez une corde à vide ; le numéro de corde s'affiche. Ajustez la mécanique jusqu'à ce que le centre du cadran s'allume en vert et que les deux indicateurs latéraux soient allumés.

Comment changer la fréquence de référence (La4) ?

Maintenez enfoncés simultanément les boutons MODE et STREAM/CENT jusqu'à ce que le dernier chiffre de la fréquence clignote. Utilisez MODE pour augmenter de 1 Hz ou STREAM/CENT pour diminuer de 1 Hz. Laissez quelques secondes pour confirmer la valeur.

Comment activer le mode Haute Luminosité ?

Maintenez le bouton STREAM/CENT enfoncé pendant au moins deux secondes. Le cadran devient plus lumineux. Pour revenir au mode normal, maintenez à nouveau deux secondes.

Que signifie la fonction Accu-Pitch Sign ?

Lorsque la fonction est activée, les lumières du cadran convergent vers le centre lorsque l'accord est correct et stable. Pour l'activer/désactiver, maintenez STREAM/CENT enfoncé tout en branchant l'instrument, puis appuyez sur STREAM/CENT.

Comment basculer entre True Bypass et Buffered Bypass ?

Utilisez le commutateur OUTPUT BUF/THRU situé sur le dessus de la pédale. Position THRU pour True Bypass (signal direct) ou BUF pour Buffered Bypass (signal avec buffer).

Pourquoi le son est-il coupé lorsque j'active l'accordeur ?

Par défaut, la sortie OUTPUT est muette en mode accordage pour éviter tout bruit parasite. Utilisez la sortie BYPASS si vous voulez entendre votre instrument pendant l'accordage.

Comment remplacer la pile ?

Dévissez la vis moletée sur le dessus de la pédale, ouvrez le capot vers le haut. Retirez l'ancienne pile 9 V, débranchez le connecteur, branchez la nouvelle pile en respectant la polarité, replacez-la dans le compartiment, refermez la pédale en veillant à ne pas coincer les fils, puis revissez.

Puis-je utiliser l'accordeur avec une guitare à 7 cordes ou une basse à 6 cordes ?

Oui. Le mode GUITAR supporte jusqu'à 7 cordes (la 7e s'affiche '7') et le mode BASS supporte les basses 6 cordes (Do aigu affiché 'C', Si grave affiché 'b').

Comment nettoyer la pédale ?

Utilisez un chiffon doux et sec. N'utilisez jamais de produits chimiques, solvants ou nettoyants abrasifs qui pourraient endommager la finition.

MODE D'EMPLOI TU3W BOSS

Before using this unit, carefully read the sections entitled: "USING THE UNIT SAFELY" and "IMPORTANT NOTES" (supplied on a separate sheet). These sections provide important information concerning the proper operation of the unit.

Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference.

A battery is supplied with the unit. The life of this battery may be limited, however, since its primary purpose was to enable testing.

Main Features

• TU-3W features a function that allows you to switch between the true bypass and buffered bypass.
  ● High Brightness mode enhances meter visibility outdoors.
• Accu-Pitch Sign function uses the motion of the meter's lights to show when tuning is completed.
  ● Guitar/Bass mode lets you tune by string number, with support for 7-string guitars and 6-string basses.
• Flat tuning is supported with Guitar Flat mode, which allows for "down" tunings up to six semitones below standard pitch.
• Switching on the tuner automatically mutes the output signal, allowing you to tune without outputting the sound.

How to Use the Tuner

1. Connect the guitar or bass you want to tune to the INPUT jack. (This switches on the power.)
2. Press the pedal switch to turn the tuner on. The CHECK indicator will light.
3. Play a single note on your guitar or bass, and tune it. The note name or string number closest to the tone being played appears in the display. Tune the instrument so that both Tuning Guide Indicators are lit and the center of the meter is lit green. (Cent display)

The meter will light farther toward the left as the pitch gets flatter, or farther toward the right as the pitch gets sharper.

* When the Accu-Pitch Sign function is on, the meter lights stream toward the center of the display when stable tuning at the correct pitch is reached.
* The meter behavior described here is when the CENT display is selected (the factory setting). The behavior is different when you've selected the STREAM display.

* The sound from the OUTPUT jack is muted when the tuner is on.

Convenient Functions

■ Having the Meter Indicate Completion of Tuning (Accu-Pitch Sign function)

When the Accu-Pitch Sign function is on, the meter lights stream toward the center of the display when stable tuning at the correct pitch is reached.

1. While holding down the STREAM/CENT button, turn on the power (insert a plug into the INPUT jack).
2. Press the STREAM/CENT button again to toggle the Accu-Pitch Sign function on/off. On: The meter lights stream to the center from the left and right. Off: The meter lights up at the left and right.
   * The TU-3W returns to its normal state when several seconds have elapsed without the STREAM/CENT button being pressed.
   * This setting remains stored even after the power is turned off.

■ Changing the Reference Pitch

You can adjust the reference pitch over a range of 436-445 Hz. (440 Hz is the factory default.)

1. Press the MODE button and STREAM/CENT button simultaneously. The lowest digit of the current reference pitch (e.g., "0" when set to 440 Hz) blinks in the Note Name/String indicator.
2. Press the MODE button or STREAM/CENT button to change the reference pitch. MODE button: Raises the reference pitch by 1 Hz. STREAM/CENT button: Lowers the reference pitch by 1 Hz.
   * If you allow several seconds to elapse without pressing the MODE button or STREAM/CENT button, the TU-3W will return to normal operation.
   * When you turn on the power, the current reference pitch will be displayed for several seconds.

* This setting remains stored even after the power is turned off.

■ Changing the Meter's Brightness (High Brightness mode)

By switching the meter to High Brightness mode, you can increase its visibility when performing outdoors.

To switch to High Brightness mode, hold down the STREAM/CENT button for two seconds or longer. To return to normal brightness, hold down the STREAM/CENT for two seconds or longer once again.

* Normal brightness is automatically selected when you turn on the power.

* Power cannot be supplied from the DC OUT jack when the TU-3W is running on batteries.

13.DC IN Jack

Accepts connection of an AC Adaptor (PSA series: optional). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.

* Use only the specified AC adaptor (PSA series), and connect it to an AC outlet of the correct voltage. Do not use any other AC adaptor, since this may cause malfunction.

* We recommend that you keep batteries installed in the unit even if you'll be powering it with the AC adaptor. That way, you'll b continue a performance even if the cord of the AC adaptor gets accidentally disconnected from the unit.

1. OUTPUT BUF/THRU Switch

Switches between true bypass and buffered bypass.

Precautions When Connecting

* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.
* Some connection cables contain resistors. When connection cables with resistors are used, the sound level may be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.
* If you'll be using the TU-3W for an extended time, we recommend that you use an AC adaptor.
* Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

When powering up: Turn on the power to your guitar amp last. When powering down: Turn off the power to your guitar amp first.

* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally.

* When operating on battery power only, the unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible.

Changing the Battery

When the indicator goes dim or no longer lights while the effect is on, it means that the battery must be replaced.
