[. . . ] EPI Emergency Page Interrupter Instructions ® Biamp Systems, 10074 S. W. Arctic Drive, Beaverton, Oregon 97005 U. S. A. [. . . ] The front cover may now be removed, exposing the internal circuit board. With the sound system turned off, route cables through the front cover access holes and make the proper signal and contactclosure connections to the EPI (see diagram below). The Program Input, the Page Input, and the Output are all unbalanced line-level connections, wired with high to (+) and ground to (gnd). Program Input is from the normal signal source. This can be the output from a microphone mixer or a music source (CD, cassette, etc. ). Page Input is from the paging signal source. This can be the output from a microphone preamp, a telephone system, or a distributed speaker line. Transformer isolation may be required for proper interface to telephone or distributed speaker systems. The EPI Output goes to the input of the sound system equalizer or amplifier. When used with the Advantage IWA or RPM Series powered mixers, insert the EPI at the mixer Main (or Zone) patch point. Connect the mixer Main/Zone Out terminal to the EPI Program Input (+), and connect the EPI Output (+) to the mixer EQ In terminal. Connect the mixer Com terminal to either the EPI Program Input (gnd) or the EPI Output (gnd), but not both. [. . . ] This control is factory set fully counter-clockwise (minimum).
