Connecting and Mounting Your Speakers:
Please read the following directions for connecting and mounting your MA Series
speakers:
Connecting:
It is important that before making any connections with the speaker terminals on
your MA Speakers that your power source, amplifier and/or receiver, is completely
off.
First, determine the purpose that your MA Series Sound System Speaker will be
used for by determining whether it will be used in a 70 Volt, 25 Volt or 8 ohm
a p p l i c a t i o n .
Remove the speaker’s grille by pressing the easy mount tabs on the side of
the speaker to the left and then upward. Do this evenly on each side until the grille
can be grasp to be taken off by hand. Be careful not to bend the grille.
Once you have removed the grille and determined your application, if used for a 70
or 25 Volt application, adjust the 25V/70V selector switch on the speaker’s faceplate
to the desired 70 Volt or 25 Volt application.
Upon completing this task, determine which wattage tap best meets the sound need
of the environment the speaker will be utilized in. Usually, a wattage tap dial set at
“1.0W” - “2.5W” will be utilized for background music in an office place setting. The
higher wattage taps “5.0W” - “30.0W/40.0W” are utilized when a higher volume for
the speaker is needed to offset a louder environment. After determining your need,
gently turn the wattage dial on the faceplate of the speaker so that the indicator is
aligned with the desired wattage tap.
For an 8 ohm speaker requirement, turn dial tap to the 8 ohm indication.
This automatically overrides the transformer within the unit and the Voltage Selector
switch on the faceplate.
