page over-ride/page pass through
e page over-ride feature allows you to connect the TeachLogic amplier to the school
paging/intercom system for muting purposes. A simple connection between the in-
classroom paging speaker (typically 25v or 70v) and the TeachLogic page input will mute
all the inputs and pass the page to the speakers connected to the TeachLogic amplier.
e panel labeling is based on a 25-volt paging input signal.
e Page Input impedance switch has three labeled positions (based on power draw at
25V):
• 0.1W DR AW
• 1.0W DRAW
• MUTE OFF
Switch Setting: 0.1W DR AW 1W DRAW MUTE OFF
Impedance 5000Ω 620Ω Open circuit

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 (25v or 70v)
5. Set the slide switch to the appropriate speaker level setting
6. With the TeachLogic amplier turned ON, send a page signal through
the page input
7. Adjust the page input SENSITIVITY control so that an incoming page/intercom
signal will override any audio (mics, dvd etc) plugged into the TeachLogic amplier.
