turned down, you might hear some sound when switching the unit on/o. However, this is

normal and does not indicate a malfunction.

Anti-Feedback Function

The MOBILE BA has an anti-feedback function, which suppresses the occurrence of acoustic

feedback.

Acoustic feedback is the unpleasant howl or squeal that can occur when a microphone is pointed

toward speakers, or when the volume is high.

The anti-feedback function of the MOBILE BA is always active, in order to suppress feedback.

* If the anti-feedback function is not enough to suppress feedback, take the following steps.

• Change the direction of the microphone

• Move the microphone away from the speakers

• Lower the volume

with both 3/8-inch and 5/8-inch types.

If you’re using the MOBILE BA with a 5/8 inch mic stand,

remove the mic stand adaptor from the bottom of the

unit.

NOTE

• When placing the MOBILE BA upside down, take care not to damage the buttons or knobs, and be

careful not to let it fall or tip over.

• If you’re not using a mic stand, be sure to attach the mic stand adaptor to prevent leakage of sound

(air).

Requirements when using a mic stand

As shown in the illustration, you must use a mic stand

that can be lower than 125 cm (49-1/4”; including the

MOBILE BA), and whose legs will be 63 cm (24-13/16”)

or more when opened to a maximum width.

NOTE

• Using a mic stand that does not meet the specications above may result in damage to equipment or

injury due to the stand tipping over.

• When using MOBILE BA with a mic stand, the mic stand must be carefully placed so it is level and sure

to remain stable.

• Cables connected to MOBILE BA should be given enough slack to prevent accidents that might result

from someone tripping over them.

• To prevent accidents due to falls, do not place any object on the MOBILE BA when it’s mounted on a

mic stand.

• After attaching the MOBILE BA to the mic stand, check to make sure that it is stable before you use it.

• When disconnecting all cables, grasp the connector

itself—never pull on the cable. This way you will avoid

causing shorts, or damage to the cable’s internal

elements.

• To avoid disturbing others nearby, try to keep the unit’s

volume at reasonable levels.

• When you need to transport the unit, package it in the

box (including padding) that it came in, if possible.

Otherwise, you will need to use equivalent packaging

materials.

• Some connection cables contain resistors. Do not use

cables that incorporate resistors for connecting to

this unit. The use of such cables can cause the sound

level to be extremely low, or impossible to hear. For

information on cable specications, contact the

manufacturer of the cable.

Ground terminal

• Depending on the circumstances of a particular setup,

you may experience a discomforting sensation, or

perceive that the surface feels gritty to the touch when

you touch this device, microphones connected to it,

or the metal portions of other objects. This is due to

an innitesimal electrical charge, which is absolutely

harmless. However, if you are concerned about this,

connect the ground terminal with an external ground.

When the unit is grounded, a slight hum may occur,

depending on the particulars of your installation. If

you are unsure of the connection method, contact the

nearest Roland Service Center, or an authorized Roland

distributor, as listed on the “Information” page.

Unsuitable places for connection

• Water pipes (may result in shock or electrocution)

• Gas pipes (may result in re or explosion)

• Telephone-line ground or lightning rod (may be

dangerous in the event of lightning)

MP3-Player-Musikwiedergabe entfernen können. Per einfachen Tastendruck können Sie einen „Minus-

One“-Song erzeugen – eine für Gesangsunterricht oder Karaoke besonders nützliche Funktion.

Vorbereitungen

1. Führen Sie den Gurt durch die Halterung.

2. Befestigen Sie den Gurt am Gurt-Pin.

HINWEIS

• Nur den mitgelieferten Gurt verwenden.

• Befestigen Sie den Gurt so, dass er sich nicht versehentlich

lösen kann. Falls der Gurt locker ist, während der MOBILE

BA am Gurt getragen wird, könnte der Verstärker zu Boden

fallen, was Schäden oder Verletzungen verursachen kann.

• Machen Sie keine Dreh- oder Schwingbewegungen mit

dem MOBILE BA, während Sie ihn am Gurt halten. Dies ist

äußerst gefährlich, da sich dadurch der Gurt lösen oder,

wenn die Bewegung zu oft wiederholt wird, sogar reißen

kann.

• Der mitgelieferte Gurt ist für den ausschließlichen

Gebrauch mit dem MOBILE BA vorgesehen. Verwenden Sie

diesen Gurt nicht für andere Produkte.
