Introduction The Bogen Model MCP35A Master Control Panel provides facilities for instantaneous two-way communication and distribution of emergency pages, background music or other program material to speaker-equipped locations. The control panel has two built-in amplifiers. The intercom amplifier, rated at 20 watts, features a frequency response shaped for maximum intelligibility.

Installation Power and Grounding The MCP35A Master Control Panel operates from a 120 volt, 60Hz AC source and consumes approximately 100 watts. The AC line cord is terminated in a thee-prong plug, and should be plugged into a three-wire grounded outlet providing nominal 120 volts, 60 Hz AC. It is important that the control panel be grounded properly. Auxiliary Power Receptacle An 840-watt, three-wire grounded outlet is provided on the rear panel to supply power to accessory equipment.
Gain Adjustments (Rear Panel) Remote Emergency Microphone Paging (Rear Panel) Screwdriver-adjustable INPUT GAIN controls are accessible via the rear panel for MIC 1, MIC 2, AUX, Tel Page, Talk, and Listen. Set the controls so that signal clipping cannot occur. The MIC 2 input may optionally be used in place of the Telco Page input for use with a remote microphone (internal jumper). Figure 5 shows the connection of the MBS1000A to the MIC 2 terminals.
Associated Equipment SBA225 Room Selector Panel SCR25A Call-In Module Bogen Model SBA225 Room Selector Panels are capable of connecting up to 25 speaker-equipped locations to a PROGRAM, INTERCOM channel, or off. Each unit provides 25 lever-action, three-position, four-pole selector switches with positive detents, and red LED indicators. Caution: The installation of accessory equipment requires the removal of protective covers; exposure of internal components presents an electrical shock hazard.
TWK351 Option Appendix The TWK351 option permits light call-in on 2-conductor shielded cable. See Figure 7 for wiring diagram. General Wiring Where possible, locate the MCP35A centrally, relative to the rooms being served, in order to minimize the length of speaker cables. Orient the unit so that the operator, program director, or other parties are able to see the controls at all times. Provide adequate lighting and ventilation.
Call Switches and Speakers Call/Privacy Option Flush-mounted switches require single-gang outlet boxes. Install outlet boxes about four feet from the finished floor, in a location which will allow personnel easy access to the switch for call-in and/or communicating via the room speaker. Wall-mounted speakers should be installed at a recommended height of 7-1/2 feet above the finished floor.
