Safety Information

Please read all enclosed safety precautions before
connecting or operating this product.
Verify Line Voltage and Amperage: Your new
MB 500 Bass amplifier has been factory
configured for use with the specific line voltage
for your location:
100-120 Volts/60Hz 15A circuit for USA/Canada.
220-240 Volts/(50-60Hz) 10A circuit for
UK/Australia.
220-240 Volts/(50-60Hz) 10A circuit for Europe.
100-120 Volts/50Hz 15A circuit for Japan.
220-240 Volts/50Hz 10A circuit for Korea.
Proper AC circuit for all other countries.
Connecting
the
amplifier
specifications other than indicated above can create
safety and fire hazard, and may damage the
amplifier. If you have any questions about the
voltage requirements for your specific model, or
about the line voltage in your area, contact your
dealer before plugging the unit into a wall outlet.
Verify AC Circuit Capacity Before Use:
The high power output of your amplifier may
require heavy current draw
conditions. To insure proper performance and
avoid potential safety hazards, we recommend
connection to line circuits with amperage specified
"as above". Connecting to the same circuit used
by
other
heavy-power
high-wattage lights, may cause circuit breakers to
trip. It is always a good idea to avoid using any audio
equipment on the same AC circuit as equipment with
motors, such as air conditioners or refrigerators. This
will lessen the possibility of power variation and
electrical start-up noise affecting your sound.
Please refer to page 10 for more
instructions concerning installation.

AC Power Cord:
To avoid safety hazards, use only the power cord
supplied with your unit. If a replacement cord is
needed, make certain to use a standard IEC
compliant cord. Damaged power cords should be
replaced immediately.
certain that the AC plug is easily accessible. If you do
not intend to use the amplifier for a considerable
length of time, disconnect the plug from the AC
Mains Socket. Do not use an extention cord.
Earth Grounding Connection:
To prevent electric shock, do not remove the
grounding plug on the power cord, or use any plug or
extension cord that does not have a grounding plug
provided. Make certain that the AC outlet is
properly grounded as well. Do not use an adapter
plug with this product.

Do Not Open the Amplifier Enclosure: There
are no user serviceable parts inside this product.
Opening the amplifier enclosure may present a shock
hazard. Modification to the product will void your
warranty. If liquid enters the unit, or any metal
object such as a paper clip accidentally falls inside
the enclosure, disconnect the unit from the AC power
source immediately and consult an authorized
service station.
