POWER SUPPLY The unit is expected to work with 230 VCA – 50/60 Hz distribution system and with 24 VCC battery. In case of power dysfunction, check the outside and inside protection fuses (for 24 VCC) and eventually replace them with others of same calibration; if one of them burns out immediately, do not go on and have check the unit by qualified personnel. Take away plug from 230 VCA electric power socket and 24 VCC battery always, before removing fuses and, in any case, open the unit framing.
INSTALLATION SIGNAL INPUTS AND OUTPUTS CONNECTION Even though it has 6 input channels with a wide versatility in using (adjusted sensitivity from -51dBu to -6dBu), separated sockets are available for a quick typological connection: - MICROPHONES 6 connectors of 3 female poles XLR type with balanced audio input are used (35 of Fig.1). A 24 VCC potential for direct “phantom” supply of electret-type microphones could be joint to CH1 – CH2 – CH3 – CH4 sockets (on the same balanced phonic line), through the multi-micro switch placed on the back (37 of Fig.1); therefore, before connecting a microphone it should pay attention to the model (if dynamic or electret). In case of dynamic microphone do not insert 24 VCC; insert it with electret microphone only. 5 and 6 microphonic socket cannot be used at the same time of CD (34 of Fig.1) and TAPE (33 of Fig.1) socket use, because electronic circuits are in common: M5 with CD, M6 with TAPE. - LINE function For this function, i.e. the use of tuners and radio microphones, audio from video projectors, outside audio lines (to be protected by inserting a separator transformer), message and tone generators, etc., both microphones connectors (i.e. those remained available) and those further on described. - CD For the use of CD a couple of mono-female-RCA connectors (unbalanced audio) is arranged. Listening will be monophonic also using stereo cables directly plugged in. Using CD sockets (34of Fig.1), it will be impossible connecting anything to Microphone 5 socket, because Sensibility, Tones and Volume adjustments for “CD” are made with “Micro 5 sector” of preamplifier. - TAPE INPUT REC For the use of tape Recorders or spools 2 couples of mono-female-RCA connectors (unbalanced audio) are arranged. Listening and recording will be monophonic also using stereo cables directly plugged in. As already said, it is impossible to connect anything to Microphone 6 socket by using REC-TAPE sockets (32; 33 of Fig.1), because Sensibility, Tones and Volume adjustments for “Tape” are made with “Micro 6 sector” of preamplifier. - PRE OUT It is the preamplifier output with the independent or dependent audio signal (PRE/POST) from the Master volume regulator; it could be internally selected by JUMPER (see Fig.4); 3 female poles XLR type connector is used (balanced connector) (30 of Fig.1).
LOUDSPEAKER CONNECTIONS The device is provided with an output terminal board for the connection of up to 5 Zones at constant voltage (100V/70V internal selection) (18 of Fig.1). The outputs are presetting in factory for the connection to 100V voltage lines. For variations see Fig.3. - CONSTANT VOLTAGE LINES
- / + terminals should be used (COM and 70V/100V), with each loudspeaker provided with line transformer and parallel connected (see fig. 2). In order to achieve the maximum efficiency of the system and to take precautions from amplifier bad working, it is necessary to check the effective total power handling of the loudspeakers that has to be equal or lower than the RMS power value of used amplifier. It’s a good rule arranging a 10-20% safety margin on the amplifier power capability. FOR A GOOD SYSTEM WORKING • • • • •
Keep channel and master volume at about 80%. (10; 12 of Fig.1). Adjust the GAIN (7 of Fig. 1) to have, in normal working conditions, maximum output power (level meter = 0dB, 13 of FIG.1). Optimise intelligibility with channel equalizer. (8;9;11 of Fig.1). Reduce MASTER volume (12 of Fig. 1) in order to obtain the required power. Be sure that mass commutator (29 of Fig. 1) is in mass-connected position.
OPTIONAL CARDS Their insertion has to be made in an authorized assistance centre or directly in factory C714

NOTE: If JP4 on the MR30 optional card is ON (See Fig.5), the priority level become First on First with the CH1 ones, the first activated exclude the other. When the priority is get activated, all the other inputs with lower priority level softening The “Priority” order could be active by different way in according to the input: • CH1 – To close the normally open contact PRIORITY CONTROL (19 of Fig.1) • CH2 / RRX-3 – By the TALK push button on Remote Controller RCX-5 (OPTIONAL). • CH3 – When one signal comes from to the CH3 input if the VOX function is active. • MR30 – When the playing starts.
-PRIORITY ALARM/NORMAL On the back panel is available the PRIORITY micro-switch (20 of Fig.1), It allows to set the priority in NORMAL or ALARM mode. • NORMAL – When the priority is get active the signal goes to the speaker lines selected by the switch on the frontal panel only (15 of Fig.1). • ALARM – When the priority is get active the signal goes to all the speaker lines connected (ALL) This function is not available for the Remote Controller RCX-5, for this must be considerate only its set-up. -VOX CH3 input is arranged for the connection to tel. exchanger. To make this connection have to be active the “VOX” function by the micro-switch on the back panel (36 of Fig.1). If this function is active when one signal comes from the tel. exchanger the channel priority become automatically active and the telephonic signal goes to the loudspeaker lines. DIN-DON function could be related with VOX by micro-switch (36. of Fig1), which get active the C714 DIN DON (OPTIONAL) card when the CH3 priority function becomes active. -SPEAKER SELECTOR The device is provided with an output terminal board for the connection of up to 5 Zones at constant voltage (18 of Fig.1). The power could be directed to one loudspeaker line only, to all or only some. The output lines could be selected on the amplifier by the switch on the frontal panel (15 of Fig.1) or in remote place by the Remote Controller RCX-5 (OPTIONAL) The active loudspeaker lines are indicated by Led (14 of Fig.1).
