Options

LPC4 Loop Priority Control Option

The LPC4 is used to interface the school sound system with satellite systems, such as those found in gymnasiums, multi-purposerooms, etc. The option also provides emergency seizure of the satellite system and bridging of their outputs into the main system. Refer to figure 1.

Figure 1 - Wiring Diagram, LPC4 Loop Priority Circuit

MCP-EXPInput Expander Option

The MCP-EXPExpander Panel may be used to increase the input capabilities of the sound system. Each panel has two banks of four switches and adds up to eight additional inputs to the MCP35A. Each bank may be connected to the microphone input (MIC1 or MIC2) or AUX input of the MCP35A. Banks may be interconnected, allowing all eight inputs to feed into one MCP35A MIC or AUX input. A multiple expander panel is easily interconnected to further increase the input capacity of the system.

An input is provided on each bank to replace the MCP35A MIC or AUX input into which the expander is connected. This input is accessed when all switches in the bank are in the out (off) position. When a switch is placed in the on position, the input from each high-numberswitch on the bank is overridden, i.e., the input on switch 3 overrides the input on switch 4, the input on switch 2 overrides the input on switches 3 and 4, and the input on switch 1 overrides the inputs on switches 2, 3, and 4.

Vertical 0.156 centerlines headers are provided to connect balanced or unbalanced microphones and auxiliary equipment (tuners, CD players, tone generators, etc.). The panel is designed for easy rack mounting and occupies one rack space.

ASF4 Alarm-SignalingOption

The ASF4 option provides four distinct tones for use as a manually-operatedclass change or for alarm signaling purposes (slow whoop, chime, steady, and interrupted tone). Tones are activated by remote contact closure. (Note: If the MCP35Abuilt-intone signal generator is not used for time signaling, it can be used as asingle-tonealarm and would require only a remote contact closure.) Refer to Figure 2.

PBA3 Push-ButtonAlarm Panel Option

The PBA3 Alarm Panel is used with the ASF4 feature to provide activation of three separate alarm signals and includes a reset button. Refer to Figure 2.

Figure 2 - Wiring Diagram,ASF4 Alarm Signaling with PBA3

CPP Handset Communication Option

The CPP option uses the Bogen TPS4 panel to provide for control center-to-classroomandclassroom-to-classroomphone communications. The TPS4 includes: an ON/OFF switch, which disconnects the intercom function of the MCP35A to allow private telephone conversations; a CALL button which transmits a call tone to selected speakers; anIN-USELED, which illuminates when handsets are in use; and a disconnect function, which illuminates an LED and sounds a tone when all handsets areon-hook.Requires the Model HS201C or HS202C staff classroom phone and Model HS201C phone at the console. Refer to Figure 3.

Connections

Two terminal strips are included to connect the HS201C telephone handset and power supply. Connect the HS201C to the terminal strip labeled HS-20and GND. Connect a power supply to the terminals labeled +12V and GND. Be sure to observe polarity.

Operation

Receiving a Call From a Staff Station

1. When the call-inswitch at a staff location is activated, the corresponding LED on the room selector panel will illuminate and a tone will sound. Answer the call according to the instructions printed on the MCP35A under INTERCOM.

2. To speak over handsets, instruct the staff location to pick up the handset. Then pick up the console handset and press the ON/OFF switch on the TPS4 (suspends normal intercom communication). The green IN-USELED will illuminate.

3. When a conversation is finished, press the ON/OFF switch to release it. Note that if both parties hang up before the TPS4 is turned off, the red DISCONNECT LED will illuminate and the call-intone will sound (returning the switch to the OFF position will extinguish both). Return the room selector switch to OFF or intercom communication will resume.

Calling a Staff Location

1. Press the ON/OFF switch on the TPS4 and pick up the console handset. Select the station to be called by placing the appropriate switch on the room selector panel in the “C” position.

2.Call the staff location by pressing the CALL button, which sends a call tone to the station loudspeaker. Wait for the other party to respond by picking up the handset.

3.When the conversation is finished, follow step 3 under Receiving a Call From a Staff Station.

NOTE: Alternate Method - Call the station using the INTERCOM function of the MCP35A, then follow steps 2 and 3, underReceiving a Call From a Staff Station (page 6).

Calls Between Staff Stations

Two staff stations can communicate privately after being connected by the operator at the console (place each room selector switch in the “C” position). The console operator may leave the conversation by hanging up the handset. As long as the two staff handsets are off hook, the green IN-USELED will illuminate. When the handsets are returned to the switch hook, the DISCONNECT LED will illuminate, and theCall-InTone will sound at the MCP35A. At this point the operator resets both the room selector panel switches to OFF and presses the ON/OFF switch on the TPS4 to release it.

SCT Six-CircuitTime Signaling Option

The SCT option is used with the 6-circuitmaster clocks and the Bogen TZMA Time Zone Relay module, to provide automatic distribution of class change signals. Class change signal interrupts programming only at those speakers programmed, via the TZMA, to receive the signal. Requires a dedicated time signaling amplifier, a dry contact closure for each circuit plus a common closure. Refer to Figure 4.

MCPB Program Control Panel

The Bogen Model MCPB is a program control panel designed to operate with Bogen Series 2233R Centralized School Sound Systems. It includes input and pre-amplificationfacilities, as well as monitoring control for a separately amplified program channel (Channel B). The panel interfaces with the Bogen Model MCP35A Master Control Panel (which provides the Channel A program facilities and MCPB power supply), the SBA325 room selector and annunciator panels (used to place selected speakers on the A or B program busses, or select intercom function) and a separate Channel B program amplifier.

The MCPB includes inputs for two Lo-Zmicrophones and an auxiliary program source (e.g., CD player/receiver). Rear panel mounted input gain controls are provided to adjust the input level of each source. Phantom power is available for the microphone inputs, selectable with a printed circuit board jumper (see page 11).

Selection of the Channel B program source is by simple push button operation, following the color-codedguidelines. Atwo-positionswitch (MONITOR A/B) allows selective monitoring of either program channel through thebuilt-inmonitor speaker on the MCP35A control panel. A level control and LED meter are provided to adjust and visually monitor the level.

A special All-Callfeature overrides the Channel B bus when the MCP35A is used to make emergency announcements, telephone pages, orAll-Callannouncements.

Interconnection with the MCP35A, SBA325 room selector panels, and Channel B program amplifier are easily accomplished. The panel is finished to match the associated sound system equipment and uses only one rack space.
