UNPACKING Your unit was carefully checked before leaving the

16、factory; in- spect the shipping container and the 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 material, notify the carrier immediately and place you

17、r claim. POWER AND GROUNDING The MCP35 Master Control Panel operates from a 12OVAC, 60Hz source and consumes no more than 100 watts. An AC line cord, terminated in a three-prong plug, is provided. The line cord should be plugged into a three-wire grounded outlet pro- viding a nominal 12OVAC, 6OHz po

18、wer source. It is important to ground the unit; therefore, if a three-wire outlet is not available, an adapter such as Leviton No. 5017 should be used to convert a standard two-wire outlet for use with three-wire plugs. The adapter is provided with a grounding pigtail which should be connected to th

19、e screw holding the wall plate to the receptacle. In some areas, the wall plate screw is not grounded. In this case it is necessary to connect a grounding wire from the EARTH GND terminal on the rear chassis of the MCP35 to a water or steam pipe. AUXILIARY POWER An 840-watt, three-wire grounded outl

20、et is provided on the rear panel to supply power to accessory equipment. Auxiliary equipment connected to this outlet will be grounded, provided the Master Control Panel line cord has been properly grounded. 8 OHMS I SECONDARY L-J 25 VOLTS PRIMARY COM 4 2 I 1 7 2 $, WATTS The MCP35 Master Control Pa

21、nel is designed for 25-volt con- stant voltage distribution systems. All system loudspeakers must be provided with line-matching transformers. CAUTION Speakers and transformers must be properly matched with respect to power requirements. INPUT CONNECTIONS MICROPHONE INPUTS-terminal strips on the rea

22、r of the MCP35 provide for two low-impedance balanced or unbalanc- ed microphone inputs. Two-conductor shielded microphone cable should be used.

25、nel Only) Gain adjustments are made with a screwdriver at the rear chassis; set the INPUT GAIN controls so that signal clipping cannot occur. Proceed as follows: 1. Apply input(s) to the desired channel(s). 2. Set the corresponding front panel control(s) to maximum. 3. Adjust each appropriate INPUT

26、GAIN control (looking at rear panel, turn clockwise to increase or counterclockwise to decrease gain) so that the red “0” (overload) LED lights; then, turn counterclockwise only until the LED is extinguished. MODIFICATIONS Defeating MIC 1 to CONSOLE MIC configuration: Locate and loosen the two screw

27、s securing the jumper link on the rear chassis terminal strip connecting the MIC 1 HI terminal to the CONSOLE MIC terminal. (Refer to Figure 3-Rear Panel illustration.) Move the link down, away from the MIC 1 HI terminal. Tighten the screw securing the link to the CONSOLE MIC terminal. 4. Remove the

28、 l-ohm resistor (or, on some printed circuit boards, the wire jumper) behind the “S38” designation on the pc board. ASSOCIATED EQUIPMENT TIME TONE/TELCO PAGE A time tone can be put through all speakers when the CLOCK terminals are joined together through a closure, as with a Bogen CLK-6A Master Prog

29、ram Clock. Telco Page is accomplished through a telephone audio pair plus closure. The audio pair connects to a WMT-1 transformer which is plugged into the TELCO PAGE jack. A 24-ohm resistor is connected in series with the closure across the CLOCK terminals. When both are included, the time tone cha

30、nge option has precedence over Telco Page. EXTERNAL BOOSTER AMPLIFIER Model BPA-60 or BPA-125 (60 or 125 watts, respectively) pro- vides increased power output. To install, simply connect a cable, terminated with male phono plugs, from the MCP35 HI- Z BST INPUT jack to the HI-Z INPUT jack on the rea

31、r panel of the amplifier. Connect the 25V OUTPUT from the amplifier to the l/4 phone jack (25V BST OUTPUT).

NOTE: All other specifications are the same as those given for the MCP-35. DESCRIPTION PI-35 System Bogen Multi-Graphic Model PI-35 High-Powered Intercom utilizes th

34、e MCP35 Master Control Panel and one SBA225 Room Selector Panel. Facilities are provided for the distribu- tion of program information from external microphones, tuner, cassette player, or other background music source. SI-35 System Bogen Multi-Graphic Model SI-35 Desk-Top Control Center incorporate

35、s the MCP35 Master Control Panel, and has a capacity of 75 speaker stations when configured with three SBA225 Room Selector Panels. If a built-in program source is desired, an FM/AM tuner can be incorporated with one or two switchbanks; an FM/AM tuner with cassette player can be used with one switch

36、bank. Calls from a speaker-equipped location in an PI-35 or SI-35 system, and speaker or staff handset in a Series 115 system, are received with light annunciation and a tone signal. When selected for intercom, or when a speaker station is monitored from the control center, a supervisory tone is rep

37、eated at regular intervals. Stations equipped with a CA-16 Call-In Switch can prevent monitoring and still hear incoming mes- sages when the switch is placed in the PRIVACY mode. ASSOCIATED EQUIPMENT SWITCHBANKS Bogen Model SBA225 Room Selector Panels are capable of connecting up to 25 speaker-equip

38、ped locations to a PRO- GRAM, OFF, or INTERCOM channel. Each unit provides 25 lever-action, three-position, four-pole selector switches with positive detents, and red LEDs. Switch positions are graphically identified as PROGRAM A, OFF 0, and INTERCOM C, each with color-coded indicia; the program cha

39、nnel color-code is amber, the off position color- code is black, and the intercom channel color-code is green. Each switch functions as follows: A-(Up position, amber color-code)-connects a speaker station to the Program channel for distribution of microphone, tuner, cassette player, or phono genera

40、ted in- formation; is overridden by EMERGENCY PAGE. 0-(Center position, black color-code)-disconnects a speaker station from the system; is overridden by EMERGENCY PAGE and ALL ROOMS pushbuttons. C-(Down position, green color-code)-connects a speaker station to the Intercom channel; is overridden by

41、 EMERGENCY PAGE pushbutton. Program information will not be distributed to this station if the switch is left in this position. A white tabular strip, protected by a clear plastic snap-off cover, is provided for labelling the station controlled by each selector switch. When stations are identified b

42、y numbers, it is common practice to connect and label the switches from left to right (as viewed from the front or operators position), starting at the uppermost switchbank. Calls from staff stations are initiated by momentary depression of a call-origination switch, which lights the corresponding L

43、ED on the SBA225, while sounding a repetitive tone to bring attention to the call. The LED remains “on” until the call is acknowledged by placing the appropriate switch to the “C” position. Each switchbank panel has provisions for accommodating the add-on Bogen Model TZMA Time Zone Module, providing

44、 up to six zones of time signalling, and/or the Model SCR25 Call-In Module, providing the circuits necessary when using call-origination switches which do not contain silicon-con- trolled rectifiers. SWITCHBANK MODULES SCR25 Call-In Module Bogen Model SCR25 Call-In Module is an annunciator latching

45、control bank designed for use with the SBA225 Room Selector Panel. The SCR25 provides 25 silicon-controlled rectifiers and programmable DIP switches and permits the use of a momen- tary switch (such as the Bogen Model CA-17) and/or a telephone handset with fixed closure for call-in from a staff loca

46、tion. The silicon-controlled rectifiers provide annunciator latching, keeping the appropriate LED annunciator lamp illuminated until the call is acknowledged. DIP switches are provided to select the method of call-in (momentary switch and/or fixed closure handset). The module is connected to the swi

47、tchbank panel by a simple plug-in method and is constructed of G-10 glass epoxy. Termi- nation is via wire wrap or centerline connectors (Panduit or equivalent). TZMA Time Zone Module Bogen Model TZMA Time Zone Module is designed for use with the SBA225 Room Selector and Annunciator Panel. The modul

48、e provides 25 six-position DIP switches and allows each staff station circuit to be programmed to any of six time zones for time signalling. Sealed relays, capable of handling 25 watts of audio power, are used to ensure trouble-free operation. The module is connected to the switchbank panel by a sim

49、ple plug-in method and is constructed of G-10 glass epoxy. Ter- mination is via wire-wrap or centerline connectors (Panduit or equivalent). STAFF STATION EQUIPMENT Staff station equipment may include wall- or ceiling-mounted cone loudspeakers, or horn-type loudspeakers used to assure clear, intelligible communications in relatively high-noise areas. Staff stations reply hands-free when called. To initiate c
