Spectrum III
page over-ride/page pass through
The page over-ride feature allows you to connect the TeachLogic amplifier 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 amplifier
Unplug the 2 pin green Phoenix connector
Connect the speaker cable from the paging system to the 2 pin
Phoenix connector of the Page input
Reconnect the 2 pin green Phoenix connector
Determine the signal level of the paging system (25v, 70v, or 100v)
Set the slide switch to the appropriate speaker level setting
With the TeachLogic amplifier turned ON, send a page signal through
the page input
Adjust the page input SENSITIVITY control so that an incoming
page/intercom signal will override any audio (mics, dvd etc) plugged
into the TeachLogic amplifier.
In the event of a loss of AC power, the TeachLogic amplifier will continue to pass
the page on to only one of the speaker connections as outlined on the following
diagram. Only the upper left speaker outputs will pass page without power.
