Maxim III

Connecting the system
Before connecting, the installer is responsible for determining that the TeachLogic amplifier
impedance is compatible with the paging system.
1. Unplug the 2-pin green Phoenix connector
2.
Connect the speaker cable from the paging system to the 2 pin Phoenix connector of the Page input
3. Reconnect the 2-pin green Phoenix connector
4.
Determine the signal level of the paging system (25 v, 70 v, or 100 v)
5. Set the slide switch to the appropriate speaker level setting
6. With the TeachLogic amplifier turned ON, send a page to test the mute function.
7. Adjust the sensitivity control to ensure the Maxim™ III senses the page signal noting that some pages
with quiet voices will require greater sensitivity settings. The system will maintain its mute until about
11 seconds after the page signal falls below the threshold for sensing. Thereupon, the wireless mics
are unmuted, and other audio levels are ramped up gradually to their prior volume (before mute).
8. In the event of a loss of AC power, the TeachLogic amplifier will continue to pass the page on to two of
the speaker connections as outlined on the following Diagram A. Only the upper left and lower right
speaker outputs will pass page without power.
