Once you determine the number of speakers and the minimum
amplifier power for the installation, you are ready to select the
system amplifier. A 70V paging amplifier is very easy to select.
• Locate amplifiers on the chart that have a wattage equal to or
higher
than the minimum amplifier power of your application.
(Amplifiers with power capacities greater than this number will
not damage the speakers. The extra power available is simply
not used.)
• Determine the amplifier features needed for the application
(see the Site Survey Check List on page 72 and the Amplifier
Features Chart on page 78).
• Using the chart on page 78, find an amplifier that offers these
features. As long as the wattage of the selected amplifier is
equal to or higher than the minimum amplifier power, the
amplifier will work well for the application.
If you think the application’s system may need to expand in the future
(this is often the case with new constructions and relocating com-
panies), you may want to select an amplifier with a greater power
capacity now.
Example:
An application requiring 18 CS1EZ Ceiling Speakers requires
a minimum amplifier power of 18 watts, so an amplifier with a
power rating of 18 watts minimum is needed. Now, look at the chart
on page 78 to determine which amplifiers provide the necessary
wattage to drive the speakers as well as provide the amplifier
features that are most appropriate for the installation. Since the
minimum wattage needed is 18, the amplifier with the lowest power
usable for this installation is 20 watts (model C20). However, if the
C20 does not have the features required for the application, such
as bass and treble controls, you can select any amplifier of
greater wattage that offers the specific features. For instance, you
might select the TPU35B or C35. Both of these amplifiers have a
higher wattage than the application’s minimum amplifier power
needed and provide the desired features because they have bass
and treble controls. Either of these amplifiers will work well for
this application. Plus, there is room to expand the system on a 35W
or higher amplifier without the need to purchase an additional
amplifier in the future.
