RTI 10-210655-20 AMV-340 3×1 Audio Mixer Amplifier

AMV-340 3×1 Audio Mixer Amplifier

The AMV-340 is a compact-sized professional-grade Class-D 70/100V
amplifier for commercial distributed speaker systems. Capable of 70 or
100 Volt transmission of audio signals, the amplifier allows the distance
between amplifier and speaker to be extended by a factor of 10 and more.
AMV-340 is designed for hotel, bar/restaurant grocery store application
or any application where long-distance wiring of multiple speakers is
required. Also, it can be used as a PA system, playing background music
and making announcements via the connected microphone
