3 Applications
The amplifier PA-1250D with a 250W RMS output power is specially designed for PA systems. It is equipped with a switch mode power supply unit and a class D power amplifier and provides an efficiency of more than 90% . An LC display shows the most important operating parameters and allows to make settings via a menu.
4 Setting up the Amplifier
The amplifier is designed for installation into a rack for units of a width of 482mm (19") but can also be used as a tabletop unit. In order to ensure sufficient cooling of the amplifier, air must always be able to flow freely through all air vents.
4.1 Rack installation
For rack installation, the amplifier requires a space of 2 RS (2 rack spaces = 89mm .To prevent the rack from becoming top-heavy, insert the amplifier into the lower section of the rack. The mounting brackets are not sufficient for fixing it safely; additionally use lateral rails or a bottom plate to secure the unit.
The hot air given off by 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 (e.g. DPVEN-03).
5 Connecting the Amplifier
All connections must be made by skilled personnel. Always switch off the amplifier before making any connection!
To make handling easier when screwing on the connection cables, all green screw terminals (15, 17, 18, 19) can be disconnected from their plug-in connections.
1) For making announcements and reproducing music, a PA preamplifier (e.g. PA-1414MX) is required which allows connection of microphones and audio units (e.g. CD player, radio). Connect the output of the preamplifier to the input PGM IN (18).
2) For making emergency announcements or other important announcements, the PA-1250D is equipped with the input PRIORITY IN (19). As soon as a line level signal is available at this input, the input PGM IN will be muted so that only the emergency announcement is audible.
3) Connect the PA speakers to the screw terminal SPEAKER OUTPUT (17). Make sure that the total load of the speakers does not exceed 250 W RMS; otherwise the protective circuit will respond and reduce the volume of the amplifier or mute it (www.chapter 6.2.3).
4) To ensure continued operation of the amplifier after mains failure, connect a 24V emergency power supply unit (e.g. PA-24ESP) to the screw terminal 24V = (20) .
5) For remote-controlledactivation/deactivation, connect a switch to the screw terminal AC PWR REMOTE (15).
6) For remote control of the amplifier (e.g. via a PC) and for showing the operating parameters of the amplifier on a display, an RS-485 interface is provided. For data transmission, the Modbus protocol is used (page 26).
Connect the PC to the jack RS 485 IN (14). To operate another unit by remote control, connect this unit to the jack RS 485 OUT.
7) Finally connect the mains cable provided to the mains jack (13) and then connect it to a socket (230V / 50Hz) .The LED STAND-BY (12) lights up.
6 Operation
1) Press the button POWER (11) to switch on the amplifier. The LED STAND-BY (12) is extinguished; the LED ON (7) lights up and the display (1) is illuminated. To switch off the amplifier (i.e. to switch the amplifier to the standby mode), keep the button POWER pressed until the display is extinguished.
Alternatively, switch on / off the amplifier by remote control via a switch connected to the screw terminal AC PWR REMOTE (15). When the amplifier has been switched on by remote control, the
display shows [REMOTE] beneath the line STATUS.
Note: The amplifier can only be switched on / off by remote control when it has not been switched on with the button POWER. To allow for remote-controlled activation / deactivation even though the amplifier has been switched on with the button POWER, open the connected switch and then keep the button POWER pressed until the LED STAND-BY lights up.
2) To adjust the volume, first press the knob PUSH / LEVEL (8) for two seconds until VOLUME SETTING appears on the display. Then turn the knob to adjust the volume. Finally briefly press the knob to exit the volume setting menu and to save and lock the volume adjusted.
The display indicates the volume adjusted:
VOLUME [00] [99]
When a specific volume has been reached, the green LED SIG (7) lights up. The red LED CLIP lights up when the amplifier is being overloaded; reduce the volume accordingly.
3) Make all other settings via the menu.
Note: When in a menu, press a button within 30 sec onds; otherwise the menu will be deactivated and any settings you may have made will be discarded.
a) Press the button MENU (2) for two seconds until EDITING MODE flashes on the display.
b) Press the knob PUSH / LEVEL. The setting menu appears (fig. 3).
c) The first menu line BATTERY? is selected. Use the button SELECT (3) to define if the voltage of an emergency power supply unit connected is to be monitored (YES) or not (NO).
Note: If you use the unit PA-24ESP from MONACOR for emergency power supply, deactivate monitoring (OFF). Since the 24 V power of the PA-24ESP is only available in case of a main's failure, the PA-1250D would report this as a fault even in normal mains operation.
d) To go to the next menu line, press the button MENU; to change the setting, press the button SELECT:
H_P_F? to activate/deactivate the high-pass filter (200Hz) for the input PGM IN (18)
