PRODUCT DESCRIPTION:
 
480W POWER AMPLIFIERS
This is a new range of power units designed specifically for professional sound-broadcasting systems with service and emergency messages. Thanks to the great reliability of the protection circuits used, combined with an attractive appearance and the very tough structures, the
MPA range constitutes the ideal product for quality amplification, with a particularly interesting price/ performance ratio. If this amplifier is used in emergency systems, it is possible to   disable all the front-panel controls (tone and volume controls).
In this way it is possible to prevent the levels set at the time of commissioning the system   from being altered accidentally. 
 
Balanced line input/output (XLR-F and XLR-M sockets, with adjustable sensitivity).
Unbalanced line input (double RCA socket)
MBT 1101 microphone station input (RJ45 socket)
Telephone/emergency audio input for priority calls with adjustable threshold and sensitivity
Front panel overall volume control and treble and bass controls
Rear-panel selector switch for enabling/disabling front-panel tone and volume controls
Constant voltage (50/70/100 V) or 8 Ω impedance loudspeaker line output.
LED-type Vu meter for clear and immediate monitoring of output power
Contacts for activating precedence on line input
Alerting signal (chime) with level control
Selectable 230/115 VAC and 24 VDC mains power supply
