Owner’s Manual
Thank you for purchasing a Yamaha BA-10 Bass Amplifier.
To get the best results and longest life out of your BA-10, we recommend that you carefully read this manual,
and keep it in a safe place for future reference.
To avoid possible damage do not expose the unit to:
direct sunlight
very high or low temperature/humidity
sand or excessive dust
* Especially inside a vehicle, the temperature may rise
excessively — do not leave the BA-10 in your parked car
on a sunny day!
Before connecting/disconnecting cables or turning the unit on/
off, be sure to set the VOLUME control on the BA-10 to 0.
Keep the BA-10 away from neon signs or fluorescent lighting to
prevent noise pickup.
WARNING- When using any electrical or electronic product, basic precautions should always be
followed. These precautions include, but are not limited to, the following:
1. Read all Safety Instructions, Installation Instructions, Special Message Section items, and any
Assembly Instructions found in this manual BEFORE making any connections, including connection to the
main supply.
2. Do not attempt to service this product beyond that described in the user-maintenance instructions.
All other servicing should be referred to qualified service personnel.
3. Main Power Supply Verification: Yamaha products are manufactured specifically for the supply
voltage in the area where they are to be sold. If you should move, or if any doubt exists about the supply
voltage in your area, please contact your dealer for supply voltage verification and (if applicable)
instructions. The required supply voltage is printed on the name plate. For name plate location, please refer
to the graphic found in the Special Message Section of this manual.
4. DANGER-Grounding Instructions: This product must be grounded and therefore has been
equipped with a three pin attachment plug. If this product should malfunction, the ground pin provides a
path of low resistance for electrical current, reducing the risk of electrical shock. If your wall socket will
not accommodate this type plug, contact an electrician to have the outlet replaced in accordance with local
electrical codes. Do NOT modify the plug or change the plug to a different type!
5. WARNING: Do not place this product or any other objects on the power cord or place it in a
position where anyone could walk on, trip over, or roll anything over power or connecting cords of any kind.
The use of an extension cord is not recommended! If you must use an extension cord, the minimum wire
size for a 25' cord (or less) is 18 AWG. NOTE: The smaller the AWG number, the larger the current handling
capacity. For longer extension cords, consult a local electrician.
6. Ventilation: Electronic products, unless specifically designed for enclosed installations, should be
placed in locations that do not interfere with proper ventilation. If instructions for enclosed installations are
not provided, it must be assumed that unobstructed ventilation is required.
7. Temperature considerations: Electronic products should be installed in locations that do not
seriously contribute to their operating temperature. Placement of this product close to heat sources such as;
radiators, heat registers etc., should be avoided.
8. This product was NOT designed for use in wet/damp locations and should not be used near water
or exposed to rain. Examples of wet /damp locations are; near a swimming pool, spa, tub, sink, or wet
9. This product should be used only with the components supplied or; a cart ,rack, or stand that is
recommended by the manufacturer. If a cart, rack, or stand is used, please observe all safety markings and
instructions that accompany the accessory product.
10. The power supply cord (plug) should be disconnected from the outlet when electronic products are
to be left unused for extended periods of time. Cords should also be disconnected when there is a high
probability of lightening and/or electrical storm activity.
11. Care should be taken that objects do not fall and liquids are not spilled into the enclosure through
any openings that may exist.
12. Electrical/electronic products should be serviced by a qualified service person when:
a. The power supply cord has been damaged; or
b. Objects have fallen, been inserted, or liquids have been spilled into the enclosure through
openings; or
c. The product has been exposed to rain; or
d. The product does not operate, exhibits a marked change in performance; or
e. The product has been dropped, or the enclosure of the product has been damaged.
13. This product, either alone or in combination with an amplifier and headphones or speaker/s, may
be capable of producing sound levels that could cause permanent hearing loss. DO NOT operate for a long
period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss
or ringing in the ears, you should consult an audiologist.
IMPORTANT: The louder the sound, the shorter the time period before damage occurs.
14. Some Yamaha products may have benches and/or accessory mounting fixtures that are either
supplied as a part of the product or as optional accessories. Some of these items are designed to be dealer
assembled or installed. Please make sure that benches are stable and any optional fixtures (where applicable)
