PA6600 - Receiver Monacor - Free user manual and instructions

USER MANUAL PA6600 Monacor

New option for microphone priority starting from serial number ...-03

For all devices whose serial number ends with "-03", the priority of the input channels CH1–CH3 and of the siren can be switched off. To do this, disconnect the device from the power supply and remove the housing cover. Set the switch SW1 in the rear part of the device to the position OFF (drawing). The signals of the channels CH1 – CH3 and of the siren will then no longer fade out the signals of the channels CH4 – CH5, for example, but they will mix with these signals.

It will, however, still be possible to individually assign a higher priority (3rd priority level) to the channels CH1–CH3 by means of the corresponding switch MIC PRIORITY.

4 Installation of Additional Modules

WARNING

Additional modules must only be installed by specialized personnel. Prior to opening the amplifier disconnect the mains plug from the socket; otherwise, you will risk an electric shock!

If an emergency power supply unit is connected, disconnect it from the connections 24 V= (37) so that the amplifier will be out of operation.

4.1 Connection module for PA-6000RC

For the connection of the zone paging microphone PA-6000RC (fig. 3) available as an accessory, the connection module supplied with the microphone must be installed into the amplifier.

4.1.1 Installation and connection

1) Screw off the housing cover of the amplifier and the cover (33) on the rear panel of the amplifier.
2) Connect the 3-pole line AS 903 of the connection module to the jack CN 903 of the amplifier – see layout plan on page 48.
3) Insert the module into the cutouts which are uncovered when the cover is removed (33) and screw it on.
4) Connect the black-red 2-pole line A of the amplifier to the jack CN 801 of the module.

However, if also the anti-feedback module PA-6FR is installed, connect the 2-pole line A to the jack CN 801 of the PA-6FR and the 2-pole line AN 801 of the PA-6FR to the jack CN 801 of the connection module.

5) Connect the screened line AS 802 of the module to the jack AN 802 of the amplifier.

6) Connect the 7-pole line AS 204 of the module to the jack CN 901 of the amplifier.

7) If no digital message insertion PA-1120DMT is installed, fasten the loose 10-pole line AS 4-1 of the module with cable ties in the amplifier.

Only carry out the steps 8) to 10) with the digital message insertion PA-1120DMT installed:

8) Connect the 10-pole line AS 4-1 of the module to the jack TO RR-100 / 600 of the insertion.

9) With the jumper MS 802 of the connection module define if the announcement in the memory M 6 of the PA-1120DMT can be called via the zone paging microphone (position ON) or not (position OFF, factory setting). The memory M 6 can, for example, be reserved for an automatic alarm announcement which is only to be activated via the terminals MESSAGE FIRST PRIORITY (28).

10) In the amplifier set the jumper MS 2 on the front PCB above the level control (7) for the input 3 to the position "PRI TO PACK". Thus, the signal of the insertion takes 1st priority and its volume is not attenuated by a signal of the zone paging microphone.

4.1.2 Microphone connection and basic setting

1) Connect the jack OUTPUT (51) of the microphone to the jack INPUT of the connection module. A short connection cable is supplied with the microphone. The cable length between amplifier and microphone must be 1000 m as a maximum.

A second microphone may be connected to the jack LINK of the module or to the jack LINK (50) of the first microphone. For the connection of a third microphone, connect its jack OUTPUT to the jack LINK of the second micro-

phone. As a maximum, three microphones may be connected. The cable length between two microphones must not exceed 100 m.

Note: The combined XLR / 6.3 mm jack (42) of input 2 must not be used after connection of a PA-6000RC because it is connected in parallel to the input for the zone paging microphone.

2) When using several microphones PA-6000RC, set the switch TALK (49) to position PRIORITY at the microphone or microphones which are to take priority over the other microphones. Set the switch to position SLAVE for the remaining microphones. Thus, during an announcement from a microphone with priority, no announcement from a microphone without priority can be made. (In case of microphones of the same priority, the microphone first activated takes priority.)

3) To obtain 2^nd priority for the zone paging microphone / s, press the button at the connection module (position PRIORITY). When the button is not pressed (position SLAVE), the 4^th priority is adjusted. An overview of all possible priorities is given in chapter 5.4 “Defining the priority of the input signals”.

4) If the digital message insertion PA-1120DMT is used, use the switch DIGITAL MESSAGE (48) to define if stored announcements can be called via the zone paging microphone (switch position ON) or if they are locked (position OFF).

5) If the inputs at the amplifier are not sufficient, a line signal can be fed into the jacks AUX IN (52) [e. g. background music from a CD player]. Adjust the output level for the microphone signal and the signal from the jacks AUX IN with the control AUDIO OUT (53).

4.2 Fault detection module PA-6FD

The fault detection module PA-6FD (fig. 4) available as an accessory is especially designed for this amplifier. It generates a 20 kHz sine test tone which is fed to the amplifier. It is checked at the output HIGH IMP (25) if the test tone is present. In case of a defect in the amplifier in which case the test tone is not present at the output HIGH IMP, the LED FAULT (18) lights up. Via a relay, a signal device can additionally be activated.

4.2.1 Installation and connection

1) Disconnect the amplifier from the mains and from the emergency power supply.

2) Screw off the housing cover of the amplifier and remove the cover plate (30).

3) Insert the module PA-6FD from the outside at the place of the cover plate and screw it on.

4) Connect the 5-pole line B of the amplifier to the jack CN 601 of the module, see layout plan on page 48.

5) Connect the negative contact of the connection HIGH IMP (25) at the amplifier to the contact COM of the screw terminal Line In (62) at the module and the positive contact of HIGH IMP to the contact HOT of Line In.

6) Connect the jumper SW 1 on the monitoring module to position ON.

7) If a fault is recognized by the module, the LED FAULT (18) lights up and the relay contacts (61) close. For alarm triggering, a signal device may be connected to the contacts. The rating of the relay contacts is 1 A at \~ 120 V max. or = 24 V max.

Note: The relay contacts also close when the amplifier is switched off.

4.2.2 Calibration

An oscilloscope or a voltmeter is required which is able to measure alternating voltage up to 20 kHz min.

1) Switch on the amplifier and turn the volume control MASTER (17) to zero so that only the 20 kHz test tone is present at the speaker outputs.
2) Measure the voltage of the 20 kHz test tone at the connection HIGH IMP (25) and adjust it to \~ 2 V (5.6 Vpp) with the trimming control OSC Level (64).
3) Turn up the trimmer potentiometer Sensitivity (65) until the LED "Sense" (63) lights up. From this position, turn the potentiometer to the scale mark after the next. The LED may flicker during operation; this is not a fault.
4) After the calibration, set the control MASTER to the desired volume again.

4.3 Fault monitoring module PA-6FM

The fault monitoring module PA-6FM (fig. 5) available as an accessory is especially designed for this amplifier. Via the three relay outputs (66) signal devices can be activated in case of the following faults:

The relay contacts AC switch over if no mains voltage is present, if the internal mains fuse has blown, or if the mains switch (19) is not in the position ON.

The relay contacts DC switch over if the fuse (38) for the emergency power supply has blown or if no voltage from an emergency power supply unit is present at the connections DC POWER (37).

The relay contacts FAN switch over if the internal fan is defective or if it is not connected.

Note: All relay contacts also switch over when the amplifier is switched off.

1) Disconnect the amplifier from the mains and from the emergency power supply.
2) Screw off the housing cover of the amplifier and remove the cover plate (29).
3) Insert the module PA-6FM from the outside at the place of the cover plate and screw it on.
4) Connect the 6-pole line C of the amplifier to the jack CN 5 of the module, see layout plan on page 48.
5) Connect the signal devices for alarm triggering to the relay switching contacts (66). The imprint on the module shows the contact position in case of fault and with the amplifier switched off. The rating of the relay contacts is 1 A at \~ 120 V max. or = 24 V max.

4.4 Anti-feedback module PA-6FR

The anti-feedback module PA-6FR (fig. 6) available as an accessory is especially designed for this amplifier. The signal of input 1 is routed via the module and increased in frequency (2, 4, 5 or 6 Hz can be adjusted). Due to the frequency shift, an optimum protection against acoustic feedback is reached.

4.4.1 Installation and connection

1) Disconnect the amplifier from the mains and from the emergency power supply.
2) Screw off the housing cover of the amplifier and the cover (32) on the rear side of the amplifier.
3) Insert the module into the cutouts which are uncovered when the cover is removed and screw it on.
4) Connect the 2-pole line AN 702 (black-brown) of the amplifier to the jack CN 702 of the module, see layout plan on page 48.
5) Connect the black-red 2-pole line A of the amplifier to the jack CN 801.

6) If the connection module for the zone paging microphone PA-6000RC has been inserted before, the 2-pole line is already connected to the jack CN 801 of the connection module (dashed line in the layout plan on page 48). Disconnect the line from the connection module and connect it to the jack CN 801 of the PA-6FR. For this purpose connect the 2-pole line AN 801 of the PA-6FR to the jack CN 801 of the connection module.
7) Place the jumper MS 401 of the amplifier to position "FR".

4.4.2 Operation

After setting the amplifier into operation, set the switch ACTIVE (67) to position IN. Via input 1 make an announcement at the required volume. In the basic setting, when all DIP switches (68) are in the upper position, the frequency shift is 2 Hz. If an acoustic feedback should occur in spite of this frequency shift, adjust a higher frequency shift with the DIP switches.

5 Setting into Operation

5.1 Setting up the amplifier

The amplifier is designed for insertion into a rack for units with a width of 482 mm (19"), but it can also be used as a table top unit. In each case, air must be able to circulate through all vents without obstruction so that a sufficient cooling of the power amplifier is ensured.

5.1.1 Rack installation

For rack mounting 3 rack spaces (= 133 mm) are required. To prevent the rack from becoming top heavy, the amplifier must be inserted in the lower section of the rack. The front panel alone is not sufficient for fixing it safely. In addition, lateral rails or a bottom plate must secure the unit.

The hot air blown out at the side of the amplifier must be dissipated from the rack; otherwise, heat will accumulate in the rack which may not only damage the amplifier but also other units in the rack. In case of insufficient heat dissipation, install a ventilation unit into the rack.

5.2 Adjusting the chime sound and the priority of the insertion module

Prior to the installation of an insertion into the compartment (1), adjust the two jumpers MS 1 (chime) and MS 2 (priority of the insertion), see layout plan on page 48. These are no longer accessible when an insertion is installed.

1) Disconnect the amplifier from the mains and from the emergency power supply.
2) Screw off the cover (1) for the insertion.
3) Adjust the chime sound with the jumper MS 1 position "4T": 4-tone chime position "2T": 2-tone chime

4) Adjust the priority for the insertion module with the jumper MS 2: position "SLAVE" (factory setting):

The signal of the insertion has lowest priority. position "PRI TO PACK":

The signal of the insertion has 2^nd priority. This adjustment must be selected, for example, if announcements stored via the zone paging microphone PA-6000RC are to be called from the digital message memory PA-1120DMT.

An overview of all possible priorities is given in chapter 5.4 "Defining the priority of the input signals".

5) If no insertion is installed, screw on the cover (1) again.

5.3 Making connections

Any connections should only be made by qualified personnel and in any case with the amplifier switched off!

Numerous connections, e. g. those for the speakers, are below the protective cover (22). For connection, screw off the cover.

WARNING

Never operate the amplifier without the protective cover (22). During operation, dangerous high voltages up to 100 V are present at the speaker

terminals (23, 25). After connection, always replace the cover to prevent any contact with the terminals.

5.3.1 Speakers

1) Either connect 100 V speakers for the six PA zones to the screw terminals SPEAKER ZONES ATT. OUTPUTS (23)

Attention! Each of the six zone outputs allows a maximum load of 100W RMS by the speakers. However, the admissible total load must not be exceeded in any case:

PA-6240 240 W RMS PA-6480 480 W RMS PA-6600 600 W RMS

or a speaker group with a total impedance of 4 as a minimum to the screw terminals LOW IMP 4 (24) [when the 100 V outputs (23 and 25) are not used; otherwise, the amplifier will be overloaded]. The zone volume switches (2) do not affect this output.

2) Additional 100 V speakers which should always be switched on independent of the zone buttons (3) and whose volume is not to be reduced by the zone volume switches (2), may be connected to the screw terminals HIGH IMP 100V (25). The total load of all connected speakers must, however, not exceed the amplifier power (see note "Attention!").
3) When connecting the speakers, always observe the correct polarity, i. e. connect the positive contact of the speakers each to the upper terminal. The positive contact of the speaker cables is always especially marked.

5.3.2 Microphones

Connect three microphones with an XLR or 6.3 mm plug to the combined XLR/6.3 mm jacks (42) of the inputs 1 to 3.

1) When connecting a microphone, turn the corresponding control GAIN (43) to the right stop to position “-50”.
2) When using a phantom-powered microphone (e.g. PA-4000PTT), switch on the 12 V supply with the corresponding button PHANTOM POWER (44).

Caution! Only actuae the switch with the amplifier switched off (switching noise). With the button pressed, no unbalanced microphone must be connected to the corresponding input; otherwise, this microphone may be damaged.

3) For the priority of a microphone, set the corresponding DIP switch MIC PRIORITY (34) to the position ON (also see chapter 5.4).

Notes:

1. When using the desk microphone PA-4000PTT or PA-4300PTT, the input 1 must not be used as this input is connected in parallel to the input (46) for the PA-4000PTT and with the input (45) for the PA-4300PTT.
2. If a zone paging microphone PA-6000RC is connected, the input 2 must not be used because it is in parallel to the input for the PA-6000RC (via the corresponding connection module).

5.3.3 Desk microphone PA-4000PTT or PA-4300PTT

The desk microphones PA-4000PTT and PA-4300PTT [separately available as accessories] have been especially designed for this amplifier.

1) Use the RJ-45 jack PTT REMOTE to connect the microphone PA-4000PTT to the jack PA-4000PTT (46) of the amplifier or use the jack OUTPUT to connect the microphone PA-4300PTT to the jack PA-4300PTT (45) of the amplifier.
2) It is possible to connect two additional microphones of the model PA-4300PTT: Connect the jack LINK of the first microphone to the jack OUTPUT of the second microphone. Proceed in the same way to connect the third microphone to the second one.
3) Press the button PHANTOM POWER (44) of input 1 and turn the corresponding GAIN control (43) fully to the right to the position “-50”.

Notes:

1. Input 1 is now connected in parallel to the jacks for the desk microphones and must therefore not be used for any other input signals.
2. The overall length of the microphone cable must not exceed 1000 m.

5.3.4 Units with line output /recorder

Five units with line level (e. g. CD player, radio, mixer) may be connected to the inputs 1 to 5. Exceptions: Do not use input 1 when connecting a desk microphone to the jack PA-4300PTT (45) or PA-4000PTT (46) and do not use input 2 when operating the zone paging microphone PA-6000RC!

For background music the inputs 4 and 5 [RCA jacks LINE IN (41)] should be used because these have lowest priority.

1) When connecting the inputs 1 to 3 via the combined XLR / 6.3 mm jacks (42), turn the corresponding control GAIN (43) to the left stop to position “-10”. Do not press the corresponding button PHANTOM POWER (44).
When connecting a stereo unit to one of the inputs 1 to 3, use a stereo mono adapter (e.g. SMC-1 from MONACOR) and an adapter cable (e.g. MCA-300 from MONACOR); otherwise, the signals of the stereo centre cancel each other mutually.
2) If one of the inputs 1 to 3 should take priority over the other two, set the corresponding DIP switch MIC PRIORITY (34) to position ON. The inputs 1 to 3 always take priority over the inputs 4 and 5 (see chapter 5.4).
3) A recorder may be connected to the jacks REC (40). The recording volume is independent of the control MASTER (17) and the zone volume switches (2).

5.3.5 Inserting an equalizer or another unit

For external sound effect e. g. an equalizer may be inserted via the jacks AMP IN – PRE OUT (39): Connect the input of the unit to the jack PRE OUT and the output to the jack AMP IN.

Note: A signal interruption occurs in the amplifier if only jack AMP IN is connected or if the inserted unit is not switched on, if it is defective or not correctly connected. Then the speakers remain mute.

5.3.6 Additional amplifier

If more speakers are required than admissible for the amplifier, another amplifier is necessary. Connect the input of the additional amplifier to the jack PRE OUT (39) or REC (40). The signal for the additional amplifier is not affected by the controls MASTER (17) or by the zone volume switches (2).

5.3.7 Telephone bell or night bell

A telephone bell or night bell may sound via the PA system (e.g. during a round at night), if required.

1) Feed the control voltage for the bell (e.g. 8 V/50 Hz) to the connections NIGHT RINGER (26).
2) Press the button TEL (13).
3) Actuate the bell and adjust the volume of the ringing tone created by the amplifier with the control RINGER (11).
4) Switch the bell function on or off with the button TEL according to requirements.

Note: The bell has lowest priority.

5.3.8 Telephone switchboard

Announcements via the PA system can be reproduced from a telephone switchboard.

1) Feed the telephone signal (line level) to the terminals PAGING IN (27).
2) Adjust the volume during an announcement with the control PAGING (12).

Note: Telephone announcements have 3^rd priority.

5.3.9 Switch for announcements in all zones

For remote control of the following functions connect a switch to the terminals MESSAGE FIRST PRIORITY (28):

1. All PA zones are switched on and set to maximum volume [as with the button ALL CALL (4)].
2. When using the digital message insertion PA-1120DMT, the announcement of the memory M 6 is automatically called. For this purpose, connect the jumper MS 2 prior to installing the insertion to the position "PRI TO PACK" (see layout plan on page 48). Thus, the announcement of the memory M 6 takes first priority.

Instead of the switch, it is also possible to connect an alarm detecting contact, e. g. for an automatic fire alarm announcement.

1. If the amplifier is at the same time to be switched on by the switch or alarm detecting contact, connect a diode of type 1N4007 according to fig. 7 between the upper terminal MESSAGE FIRST PRIORITY and the left terminal POWER REM.

5.3.10 Emergency priority relays

If PA volume adjusting controls with emergency priority relays (e. g. series ATT-3..PEU or ATT-5..PEU from MONACOR) are inserted between the amplifier and the speakers, important announcements can also be heard at the volume “zero”.

1) For this purpose connect a desk microphone PA-4000PTT or PA-4300PTT (chap. 5.3.3).
2) Connect the emergency priority relay according to fig. 8 to the terminals PRIORITY RELAY OUTPUT (47). The output allows a load of 200 mA.
3) Set the switch PRIORITY at the microphone to position ON (downwards).
4) When actuating the TALK button now, the speakers are set to maximum volume by the relays.

5.3.11 Switch for switching on and off by remote control

The amplifier can be switched on and off by remote control with a switch connected to the contacts POWER REM (36). For this purpose, the amplifier must not be switched on with the POWER switch (19) or not be connected to the emergency power supply.

5.3.12 Power supply and emergency power supply

1) Finally connect the supplied mains cable to the mains jack (35) first and then to a socket (230 V/50 Hz). 2) For continuous operation of the amplifier in case of a possible mains failure, connect a 24 V emergency power supply unit (e. g. PA-24ESP from MONACOR) to the terminals 24 V= (37). With a cable length of up to 6 m, a cable cross section of 4 mm^2 is required as a minimum.

Note:

1. If the 24 V voltage from the emergency power supply unit is present at the terminals 24 V _m , the amplifier cannot be switched off with the switch POWER (19). In case of a mains failure or if it is switched off, it switches automatically to the emergency power supply.
2. Even if the amplifier is switched off, it consumes some power. Therefore, disconnect the mains plug from the socket and, if necessary, disconnect the emergency power supply unit if the amplifier will not be in operation for a longer time.

5.4 Defining the priority of the input signals

A priority is assigned to all input signals. A signal of a higher priority always covers a signal of a lower priority when both signals are present at the amplifier at the same time. Signals of the same priority are mixed. The following table gives an overview and shows possibilities of modification.

Priority Signal		Condition	Modification
1	Announcement M 6 from digital message insertion PA-1120DM	Jumper MS 2 on PRI TO PACK
		switch at (28) closed
2	desk microphone PA-4000PTT PA-4300PTT	DIP switch PRIORITY on microphone to ON	switch to OFF = 4^th priority ^2
	zone paging microphone PA-6000RC	switch on connection module to PRIORITY	switch to SLAVE = 4^th priority ^2
	chime	—	—
3	telephone switch-board at terminal (27)	—	—
4	inputs 1, 2 and 3	DIP switch (34) to OFF ^1	DIP switch to ON = 3^nd priority
	siren	—	—
5	extension insertions	Jumper MS 2 to SLAVE ^1	Jumper MS 2 to PRI TO PACK = 2^nd priority
	inputs 4 and 5	—	—
	telephone bell or night bell	—	—

^1 Factory setting
^2 The desk microphone PA-4000PTT/PA-4300PTT uses the input 1 and the zone paging microphone PA-6000RC the input 2. Via the corresponding DIP switch MIC PRIORITY (34), the microphones can also be set to 3^d priority.

6 Operation

If the amplifier is switched off and if no 24 V voltage from an emergency power supply unit is present at the terminals 24V= (37), the LED STAND-BY (20) lights up.

1) Prior to the first switching-on, set the five level controls (7) for the inputs 1 to 5 and the control MASTER (17) to position zero for the time being.
2) Switch on the amplifier with the POWER switch (19) or with a switch connected to the terminals POWER REM (36). The green LED STAND-BY extinguishes and the yellow LED POWER (21) lights up.

6.1 Adjusting the volume

1) First adjust the volume desired as a maximum for announcements of highest priority. For this purpose, press the button ALL CALL (4) for the time being. According to the equipment available, make an announcement:

a) With a digital message insertion, call the announcement from the memory M 6 via a switch at the terminals MESSAGE FIRST PRIORITY (28). Set the control LEVEL at the insertion approximately to the position 7.
b) With a desk microphone connected to the jack PA-4300PTT (45) or PA-4000PTT (46), set the level control (7) of the input 1 approximately to the position 7, and make an announcement.
c) In case of a zone paging microphone PA-6000RC, set the level control (7) of input 2 approximately to position 7, press the button ALL CALL (58), and make an announcement.
d) When using another microphone, set the level control (7) of the corresponding input approximately to position 7, and make an announcement.

2) During an announcement, adjust the volume with the control MASTER (17). In case of overload, the red LED CLIP lights up in the level indication (5). Then reduce the volume with the control MASTER.
3) To adjust the volume for normal announcements, disengage the button ALL CALL again. For this purpose, press all buttons (3) of the individual PA zones.
4) Make an announcement as described under item 1) b or d.

Notes:

1. On the PA-4000PTT /PA-4300PTT, set the switch PRIORITY to the upper position.
2. Do not make the announcement via a PA-6000RC because its volume is independent of the zone volume switches (2).
   5) Do not change the control MASTER (17) but adjust the desired volume separately for each zone with the corresponding zone volume switches (2) during the announcement.
   6) Then adjust the volume for the signals of the other inputs (e.g. background music) with the control LEVEL (7) of the corresponding input.
   7) For each input used adjust the sound with the corresponding controls "Bass" and "Treble" (6). Adjust the sound for an insertion in the compartment (1) with the controls PACK (8).
   8) It may be necessary to readjust once again the volume of the input signals with the corresponding level controls (7).
   9) Turn the level controls (7) of the inputs not used to zero.

Note: For the inputs 1 to 3, the input sensitivity can be adjusted with the controls GAIN (43). If a level control (7) must be turned up very far or almost be closed to obtain the desired volume ratio to the other inputs, modify the input sensitivity with the corresponding control GAIN.

6.2 Activating the PA zones

1) Switch on the zones to be used for PA applications with the buttons Z 1 – Z 6 (3). As a check, the green LEDs of the activated zones light up.
2) For announcements to all zones, press the button ALL CALL (4). At the same time, the volume of the zones is increased to maximum [corresponds to the adjustment of all zone volume switches (2) in position 6].

6.3 Chime

The chime sounds prior to an announcement when the TALK button at the desk microphone PA-4000PTT / PA-4300PTT or at the zone paging microphone PA-6000RC is pressed. When other microphones are used, the chime can be activated with the button CHIME (9). Adjust the chime volume with the control LEVEL (10).

With the jumper MS 1, it is possible to switch between a 2-tone chime and a 4-tone chime, see chapter 5.2.

6.4 Alarm siren

In case of an alarm it is possible to switch the siren on with one of the two buttons (15) in the control section SIREN:

Button "\~" for a wailing tone

Button “-” for a continuous tone

Adjust the volume of the alarm siren with the control LEVEL (14).

6.5 Zone paging microphone PA-6000RC

1) First switch on the PA zones in which the announcement are to be heard with the buttons SPEAKER ZONES SELECTOR (57), otherwise no announcement will be possible. To activate all zones, press the button ALL CALL (58).
2) For the announcement, keep the TALK button (55) pressed. The amplifier activates the PA zones according to the preselection under item 1) independent of the adjustments at the amplifier and increases the volume in the zones to maximum [corresponds to the adjustment of all zone volume switches (2) to position 6]. After the chime, make the announcement.
3) When using the digital message insertion PA-1120DMT, a stored announcement can also be called via the zone paging microphone if the switch DIGITAL MESSAGE (48) is in position ON:
a) Select the stored announcement with the selector switch MESSAGE BANK (56).
b) Start the announcement with the button START/ STOP (60). To stop the announcement, press the button START/ STOP again.
c) With the button REPEAT/ STOP (59), an announcement can also be made several times. The number of repeats can be adjusted on the insertion (see its operating instructions). To stop the announcement, press the button REPEAT/STOP again.

Notes:

1. The announcement of the memory M 6 may be locked (see chapter 4.1., item 9). If in this case the switch MESSAGE BANK is in position 6, the announcement last selected is reproduced.

2. If at least one zone button (3) has been pressed at the amplifier, after releasing the TALK button, the announcement selected with the

switch MESSAGE BANK is likewise started. To prevent this, leave a storage location of the digital message insertion free or delete it and select this storage location with the switch MESSAGE BANK.

4) The three LEDs POWER, SEND, and BUSY (54) give the following information:

POWER lights up when the amplifier is switched on

SEND lights up when an announcement is reproduced via the microphone or a stored announcement is called

BUSY lights up with individual announcements and with announcements via other connected microphones PA-6000RC

6.6 Desk microphone PA-4000PTT/PA-4300PTT

1) With the microphone PA-4000PT or PA-4300PTT connected, the input 1 is no longer available. As the microphone requires phantom power for operation, press the switch PHANTOM POWER (44) of input 1.
2) If the chime is to sound prior to an announcement when the button TALK is pressed, set the switch CHIME on the rear side of the microphone to the position ON (downwards).
3) Set the switch PRIORITY to position ON when:
1. the microphone is to take 2^nd priority
2. all PA zones are to be switched on and set to maximum volume when pressing the TALK button [as with button ALL CALL (4)]
3. the connected emergency priority relays are to respond (see chapter 5.3.10)
4) For an announcement keep the TALK button pressed and wait for the chime, if necessary.

7 Protective Circuit

The amplifier is equipped with a protective circuit against overload, overheating and short circuit at the speaker outputs. The power amplifier is cooled with a fan whose rotation speed depends on the temperature of the power amplifier. If in spite of this the temperature should increase too much, the amplifier is muted and the red LED PROTECT (16) lights up. In this case turn the control MASTER (17) fully to zero, wait until the LED PROTECT is extinguished, and then switch off the amplifier. Eliminate the fault, e.g.:

1. In case of overload, reduce the number of speakers connected or, if possible, adjust a lower power consumption on the speakers. Insert a second PA amplifier, if required (see chapter 5.3.6).
2. In case of overheating, provide a better air circulation.
3. In case of short circuit at a speaker output, locate the position of the short circuit and eliminate it.
