6、General Information Description This Director III Master Control Panel offers dependable program distribution and two-way intercom communica- tions. Its ease of operation can be gauged by the three-step instructions on the front panel. To further simplify the operation, the knobs and push buttons ar

7、e color-coded to match the “Follow-the-Color” channel markings on the associated switch panels: orange for intercom, green for the “A” Channel program-distribution, and blue for the optional “B” Channel program distribution. The control panel has a fifteen-watt intercom amplifier and five program in

8、puts: one dedicated to the built-in Console microphone and four that can be set for either microphones or program sources (e.g., phono, tape, tuner). The panel is compatible with the Rauland SW25, SWL25, SWT425, and SWL425 Room-Selector Panels and the newer Director III Series equipment (MCB300, etc

For more detailed information, see the “Back-Panel Connections, Controls, and Indicator” section of this manual. Both normal and emergency announcements can be made without resetting individual

10、 room switches. Controls trols for all-call and emergency announcements are stand- ard on the MCZ3OO, and an MTG100 Tone Generator can easily be interconnected to provide a variety of alerting and emergency tones.

15、库 .- MCZ300 Master Control Panel: Installation Installation .- Mechanical The MCZ300 is designed for mounting in a standard 1Pinch rack or in a turret (Rauland Model T1600 or T2600); it requires 3a inches of vertical space. Whatever the site, a well-planned equipment installation will save time and

16、assure optimum equipment performance. The following factors should be considered: 4 The location of the equipment and the type of mounting. 4 The numbee of inputs. 4 The field conversions for such options as a tone generator and input switches, and the advisability of completing them before mounting

17、 the MCZ300. 4 The addition of associated equipment, such as the MCB300 Program Control Panel. 4 The system wiring to and from each amplifier used. Rack- or Turret-Mounting Other than the normal precautions for (a) avoiding hot spots or areas with severely restricted air flow and (b) allowing suffic

18、ient clearance at the rear for accessing the equipment, the only location restriction is that the MCZ300 not be placed directly above or below a large power transformer (e.g., one in a power amplifier), which could cause hum. The procedures for installing the control panel are the same for both rack

19、- and turret-mounting. Note: The unit should not be mounted until the field .r conversions for any options have been completed. Mounting: At the selected mounting position, follow the appropriate procedures (depending upon whether the mounting holes are untapped or tapped): Step 1. Ifthe rack s bole

20、s aremt tapped, insert the NO speed nuts over the four holes that you will use. Step 2. Prepare the four supplied machine screws by placing a black metal washer and then a fiber washer over each one. Step 3. Insert the MCZ300 in the rack and fasten it with the four prepared screws. Electrical Power

21、and Grounding ., The MCZ300 receives its power via the “+28V” and “COM” terminals on its back panel. To make full use of the unit s 15watt intercom amplifier, select a power source that can supply at least 1.5 amperes for the MCZ300 itself (at least 1.7 amperes if the system includes an MCB300). Rau

22、land s PSX300 DC Power Supply, rated at 2 amperes, can comfortably handle either requirement and is the recommended choice. Alternatively, Rauland s school am- plifiers, such as the DAX60 and DAX120, can supply 1.2 amperes of 28VDC power, but would limit the intercom power to less than 15 watts. Bot

23、h of these Rauland power sources provide circuit protection. The MCZ300 is grounded to the rack via the room-se- lector panels; hence, it is important that the rack have a reliable earth ground, either through a three-connector AC power cord belonging to other equipment sharing the rack, or through

24、a direct connection to the earth. Do not turn on power to the MCZ300 until all of the system wiring has been completed and checked. Field Wiring If the MCZ300 is to be field-installed, refer to the “Back-Panel Connections, Controls, and Indicator” section of this manual and complete the system wirin

25、g as shown in the attached wiring diagram, KM0952. If the MCZ300 is part of a factory-wired system, use the wiring diagram to verify that the wiring is intact. If the system it can also be jumpered with the other tones so that all four can be fed into the MCZ300. Step 1. Remove and set aside the two

26、 hex-head screws that secure the top cover to the MCZ300, then remove the cover and place it topside-down on a suitable work surface. Step 2. Pop out the two canoe clips that secure the cover plate to the center of the back panel of the MCZ300. Discard the cover plate and the canoe clips. Step 3. Or

27、ient the MTG100 board with the component side up and the barrier terminal strip facing left. Find the screening for Jumper Jl on the lower left part of the board and install a jumper there. This will make the unit compat- ible with the 15-volt power supplied by the MCZ300. Step 4. Orient the MTGlOO

28、with its component side down. Align its terminal strip with the inside of the opening in the chassis cover: the terminal strip should protrude from the rear of the cover, and its rear bracket holes should align with the larger, oblong holes near the opening in the cover. Step 5. Use the two 632 x ?Q

29、 (WA571 screws supplied with the MTGlOO to secure it to the back of the cover. Step 6. Carefully reinstall the top cover on the MCZ300, using the two hex-head screws removed in Step 1; be sure to insert the front edge of the cover under the top flange of the dress panel. Step 7. Wire the MTGlOO to t

30、he MCZ300 as shown in the table below: Note: Terminal 20 on the MTGlOO is the chime-tone output; Terminal I is the output for the three other tones. Jumper-ins these two terminals together will enable any of the four tones to be fed into the MCZ300 (or other device). MTGlOO MCZ300 Terminal Terminal

Step 8. Complete the wiring between the MTGlOO and the device that is to activate the tones (e.g., a ma

32、ster clock and the RX1027 panel); refer to KC1309, the schematic of the MTGlOO (attached to this manual), and to the docu- mentation for the appropriate device. HS246 Emergency Telephone When connected to the MCZ300, the HS246 Emergency Telephone can be used to send an alerting tone or an announceme

33、nt throughout the system. Refer to the attached telephone wiring diagram (KM09321 and the MU300 sys- tem wiring diagram (KM09521 while performing the follow- ing steps: Step 1. Connect the audio lead of the telephone trans- mitter to Terminal J2-7 (“Ph+“). Step 2. Connect the telephone s hook-switch

34、 lead to Terminal J2-6 (“Ph- 3. Step 3. Connect the telephone s ground wire to Terminal J2-8 (“Ph. Act.“). In system operation, lifting the HS246 off-hook places a ground on the “Ph. Act.” (“Phone Activate”) terminal; this, in turn, causes the bus-gathering relay to connect the A,” “Off,” “B,” and “

35、C” Buses for an all-call function. Depressing the phone s alerting tone switch causes the tone oscillator in the MCZ3OO to generate a 1 .Zkilohertz tone. Connection to a Clock System The MCZ300 will generate and distribute single-channel time signals when a master clock s contact closure is connecte

36、d to Wire-wrap Terminal J2-5(“Clock”). When this terminal is grounded, two events occur: (1) the MCZ3OO s tone circuitv generates a l.Zkilohertz signal, and (2) the bus-gathering relay interconnects the program, “C,” and “Off” buses to distribute the tone via the all-call function.

The wiring follows the same pattern as that for “Input I”=-for example, a microphone

43、 for “Input 2” would be connected to Terminals 4 and 6, and its shield would be connected to Terminal 5 (“Corn”). An unbalanced audio source would use only Terminals 4 (hot) and 5 (“Corn”). Note: Only low-impedance microphones should be used with the MCZ300. The Rauland Model 1295 is recom- mended.

44、“Mic/Aux” Switch- These switches are inside, on the PC board. Each switch must be set to “Mic” if the corre- sponding input is connected to a microphone, or “Aux” if the input is connected to an unbalanced audio signal. “Exp” (Screw Terminal 2.3): This “Expander” terminal can be connected to the out
