Amplifier Connection
Amplifier speaker output terminals are typically
color coded with black for negative (-) and red
for positive (+). Similarly, the MB42-C has
speaker wire terminals with a black and red
color coding. When connecting speaker wire,
ensure that the positive terminal on the amplifier
is connected to the positive terminal on the
MB42-C. And similarly, the negative terminal on
the amplifier should be connected to the
negative terminal on the MB42-C.
Speaker wires typically use at least one of
several possible methods to help maintain
correct polarity, including color coded insulation
or conductor strands, or printing of text and
symbols along one side of the wire insulation.
Amplifier Considerations
The MB42-C’s impedance varies between 4 to 8
Ohms. Care must be taken to ensure that the
amplifier is capable of handling a 4-Ohm load.
Some amplifiers have a switch that must be set
to select a 4-Ohm compatible operation mode.
Improper amplifier selection or setup may result
in permanent damage to the amplifier or speaker.
The MB42-C can be used with amplifiers
between 15 to 100 watts per channel as long as
reasonable care is exercised. If there is audible
distortion, turn down the volume until the
distortion goes away. Never allow the speaker
and amplifier to play for more than a few
seconds when there is audible distortion.
Removing the Grill
The MB42-C has a removable grill that is held in
place by four friction pegs. To remove the grill,
carefully pry the grill off from edge until the
friction pegs are fully disengaged. To avoid
damaging the speaker drivers, do not touch
them either with or without the grill in place.
The MB42-C can be used without the grills
installed as long as care is taken to prevent the
drivers from damage such as by hard/sharp
objects, liquids, pets, or hands. Store the grills in
a safe dry place when not in use.
