The MA250 is a feature packed Mixer amplifier with 250W RMS output power. It features both 4-16 ohm operation and 70V/100V LMT output. The output can be divided over 6 zones – Zone 1, 2 & 3 controlled via on/off switch and zones 4, 5 & 6 via volume control. The MA250 has multiple inputs for attaching multiple sources. It features 3 microphone, 2 aux and a Bluetooth / USB input all controllable via individual volume control. It also has a FM receiver inbuilt. This enables flexibility of attaching any kind of input to the MA250 including a phone or tablet. There is an Alarm signal and evacuation signal for emergency announcements as well as a chime for public address. There is a 12V/24V output for broadcast emergency announcement and priority control as well. The MA250 is an installer delight versatile and feature packed Mixer amplifier ideal for schools / classrooms, meeting rooms, courtrooms, houses of worship, multi zone paging applications, museums, offices etc.
