Speaker Construction
Your Speco Technologies MA Series Speakers’ enclosure, consisting of the face
plate and backcan, is constructed of sturdy, flame-retardant ABS resin. The
internal wires are insulated for your protection as well. Speco Technologies takes
great pride in the craftsmanship and design of our speakers and the resulting
uality will ensure years of enjoyment and performance.
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 Vole or 8 Ohms
application.
Remove the speaker’s grille by pressing the easy-mount tabs on the side of the
speaker to the left and then upwards. Do this evenly on each side until the grille
can be grasped and 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 25V application, adjust the 25/70V selector switch on the speaker’s faceplate to
the desired voltage.
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 1W to 2.5W is an ideal level for background music in an office environment.
The higher wattage taps above 5W 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 Ohms speaker re uirement, turn the dial tap to the 8 Ohms indication.
This automatically overrides the transformer within the unit and the Voltage
Selector switch on the faceplate.
