Description

The Adastra RM120D is a compact yet highly capable mixer-amplifier built for commercial sound applications requiring clear audio and dependable performance. Delivering 120W RMS output, it drives both 100V line systems and low-impedance speakers down to 4 Ohms, making it adaptable for different installations.

This amplifier includes a wide range of inputs: XLR with switchable phantom power, two mic/line jacks, and twin RCA line inputs, plus an RCA line output for expansion. Integrated sources such as Bluetooth, a USB/SD audio player, and a DAB+/FM tuner give users a flexible choice of playback options directly from the front panel.

Designed for speech clarity, the voiceover function reduces background music when mic input 1 is active, while a 24V emergency mute ensures safety announcements are always heard. Four independent zone outputs plus one unswitched output allow sound to be distributed efficiently across multiple areas, giving installers greater control over system design.

  • 2U 19" rack mountable (rack ears supplied)
  • XLR input with switchable +20V phantom power
