DESIGN 
The Valcom Dual Input One-Way Amplified 
Interior Speakers may be used to provide 
one-way paging from one-way or talkback page 
controls.  The speakers provide a means for 
connecting one speaker to two audio sources, 
making it easy to provide features such as 
background music, group call, or emergency 
override.  These speakers can also be used to 
expand existing 70V paging systems.  When 
power and the appropriate input signal are 
applied, voice page can be made. 
 
Page Control Access 
When using the One-Way Amplified Speakers 
with a Page Control, the following equipment will 
be required: 
•  Appropriate one-way speaker 
assembly 
• Page 
Control 
•  Power Supply sized to provide 
power to operate the amplified 
speaker assemblies and page 
control.  (See Figure 1 for Page
