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. The 35-watt program amplifier ensures that program material and/or emergency announcements are clearly heard and easily understood. Front panel step-by-step instructions and color-coded lines make the MCP35A easy to operate.

Distribution of program material is accomplished by simple push-button program selection, following the color-coded guidelines. Emergency announcements to all locations take precedence over program distribution and are accomplished with a single (EMERGENCY PAGE) push button selection.

Inputs are provided for two Lo-Z balanced microphones, a Hi-Z unbalanced AUX program source (CD player/tuner, etc.), and telephone paging accessories. Booster amplifier IN/OUT connections are also provided. Provision are included to supply phantom power to microphones, distribute time signals to speakers, and make emergency all-call page announcements from telephone or remote microphone. Rear-panel- mounted and internal controls are provided to adjust the gain level of individual inputs and to enable/disable system features.

A console microphone (built-in) is normally used to communicate with a station over the intercom channel, to send emergency page announcements to all stations, and may be used as program MIC 1. It is easily defeated for external microphone applications. A built-in speaker is used for intercom communication and for monitoring program material before distribution. Provision is included to mute the speaker when the MIC 1 switch is pressed.

The MCP35A uses room selector panels to direct intercom or program to selected staff stations. Panels are provided with switches to place each room on a program channel, intercom channel, or off. Each switch position on the panel includes an LED call-in annunciator.

When a staff station is called from the control panel, a supervisory tone alerts the staff member to the call. The tone repeats at regular intervals to prevent unauthorized monitoring. Calls from staff stations may be initiated through call-in switches and can include privacy control to positively prevent monitoring. Provision is included for voice call-in from stations equipped with voice call-in switches.

The MCP35A control panel permits the user to:

Establish direct two-way communication between the control panel and any speaker-equipped location via a room selector panel and the press- to-talk/release-to-listen push button, while maintaining simultaneous distribution of program material to any other speaker-equipped location.

Make a program source selection by pressing the appropriately labeled push button corresponding to the input from either of two microphones (MIC 1, MIC 2) or one high-impedance program source (AUX), such as a tuner or CD player.

Transmit a program selection or voice announcement simultaneously to all speaker-equipped locations by pressing a program source push button and the ALL ROOMS push button.

The program level can be monitored audibly (speaker) and visually (LED).

Instantaneously transmit emergency messages to all speaker-equipped locations by pressing the red EMERGENCY PAGE push button. The emergency page feature overrides all system controls and functions and transmits the emergency message at a predetermined level.

Distribute time signals to all speaker-equipped locations.

Provisions have been made for:

•Sounding a supervisory tone over any loudspeaker selected from two-way communication. The tone alerts staff to a call and repeats at regular intervals to prevent unauthorized monitoring from the control panel.

•Staff call origination through the use of a call origination switch, which causes a repetitive tone signal to sound at the control panel and lights the annuniator lamp on the associated switch bank corresponding to the calling location. The annunciator system functions until the call is answered.

•Voice-call origination to the control panel from any location equipped with a voice call-in switch.

•Prevention of monitoring any location from the control panel when that location is equipped with a Bogen Call/Privacy switch.

•Transmission of page announcements from remote locations using the Telco Page feature, which overrides all system functions except the emergency page feature. The Telco Page may be used with the TELCO PAGE input or the MIC 2 input (internally selected).

Unpacking

The MCP35A was carefully checked before leaving the factory. Inspect the shipping carton and unit for damage caused by improper handling. If damage is found, you must file a claim with the transportation company that delivered the product.
