Description

The Adastra RM240D Mixer-Amplifier is designed for professional audio distribution in commercial spaces, combining versatile inputs with robust performance. Capable of powering both 100V line systems and standard speakers down to 4 Ohms, it offers installation flexibility for a wide range of environments.

Connectivity includes an XLR mic input with switchable phantom power, additional mic/line jacks, and RCA inputs and outputs. Built-in audio sources include Bluetooth streaming with unique device ID, a USB/SD player, and a DAB+/FM tuner, all managed by the onboard media player. These features make it easy to deliver music, announcements, or alerts without the need for external devices.

For clarity in public address, the switchable voiceover feature automatically lowers background audio when mic input 1 is in use. A 24V emergency mute input ensures vital announcements override all sources. Four switchable zone outputs plus one unswitched output allow tailored distribution to multiple areas, giving installers reliable control in complex setups.

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