Product Description
Adastra RM244V 100V Amplifier - 4 Zone / 5 Input Mixer 240W RMS
240Watt mixer-amplifier with 3 mic / line inputs, 1 AUX input and an integrated media player. Connections for mic/line inputs on jack or XLR while channel 1 provides an override option, i.e. mute for priority override. It also has 24Volt contacts for connection to a fire alarm panel to announce an emergency evacuation message if required. The multimedia section can offer playback from Bluetooth®, USB / SD or from an FM receiver. Output terminals are provided for 4 zones sharing the amplifier's 240W output, controlled by 4 individual rotary volume switches on the front panel. RJ45 inputs on the rear panel allow connection of up to two CS4 call stations to activate announcements in individual or all zones. The RM244V offers flexible 4-band handling without the weight of a quad amp and can even act as the front end in an expanded public performance system.
