Unpacking Your Bogen equipment was carefully checked before leaving the factory; inspect the shipping container and unit closely for improper handling. If the unit has been damaged, make an immediate claim to the distributor from whom it was purchased. If the unit was shipped directly to you, save all shipping materials and notify the carrier immediately and place a claim. -

Page 11: Call-In Switches
Typically the caller will say what room the call is being made from. The room selector switch for that room can then be set for a two way intercom conversation. Voice Call-In Wiring Contact the Bogen Application Engineering Department for information regarding this type of application. -
Page 12: Speakers And Speaker Wiring
However, it is best to tap the speakers at the lowest acceptable power tap in order to ensure that enough speakers can be connected to the system without overloading the system amplifier. The chart below shows the wire colors and power taps for the T725 transformers used in all Bogen distributed speakers. -
Page 13: Advanced Hook-Ups
Below are emergency telco page hook ups for various types of interfaces. The Bogen model WMT1A can be used to convert the TELCO PAGE input to a transformer-balanced, 600-ohm input for telephone paging applications. - Page 14 The Bogen model TAMB telephone interface module can be used to make a remote page through the telephone system. A Bogen TP-AP Series Interphone can be used to make a remote page. The figure below shows the connec- tion. Note: Jumper J3 on the MCP35A printed cir- cuit board must be set to the TELCO position.

Page 15: External Booster Amp
External Booster Amp An external booster amplifier (Bogen Model BPA60) can be connected when the application requires more than 35 watts. Using an external amplifier disconnects the internal 35W amp of the MCP35A. To install, connect a RCA cable from the MCP35A LINE OUT jack to the Hi-Z input jack on the rear panel of the BPA60 amplifier. -
Page 16: Twk351 Wire Converter
TWK351 Wire Converter The model TWK351 is an adapter used in instances where there is existing 3-wire (2-conductor + shield) room wiring. The TWK351 cannot be used with the SCR25A module. If 3-wire operation using the TWK351 wire converter is desired, CA10A call switches must be used (CA11A Call-In switches will not work in this application). -
Page 17: Scr25A Call-In Module
The SCR25A module can be added to allow the annunciator indicators to light from a simple SPST call-in switch (Bogen model CA17). All call-in switches must go back to the SI or PI on separate lines. It will not allow annun- ciator illumination from parallel connected call-in switches described in the Voice call-in section. -
Page 18: Si35A Model Option Enhancements
Make connections as shown in the diagram below. An auxiliary music source, such as the Bogen CR100A Radio/Cassette Player or TP30D Tuner can also be added to the SI35A. Install the component in the appropriate rack panel and make audio connections to the MCP35A AUX input. -
