The Bose® FreeSpace® DXA 2120 digital mixer/amplifier features a 6-in by 2-out design that provides signal processing, mixing, routing, paging and two-channel amplification for installed applications. It offers three versatile operating modes and is easily configured using the controls on the front panel. No external computer is required.

The DXA 2120 digital mixer/amplifier can be used in both low- and high-impedance systems. Each of the two output channels delivers 120 watts at 4 ohms or 100 watts for 70/100-volt applications. An auxiliary output provides a line level signal for system expansion. The DXA 2120 digital mixer/amplifier has six inputs – four  mic/line inputs, one page input and one direct input that overrides all other sources when a signal is detected. The four mic/line inputs connect to sources via 3-pin Euroblock connectors or dual RCA jacks. Three operating modes provide greater flexibility for installed music or speech applications:

Mixer Mode – Each input can be routed to every output simultaneously. Volume for each input can be controlled independently, or a master volume can control both outputs simultaneously.

Dual Mono Select Mode – Two input sources are available for each output channel. Volume control and source selection are available in each zone.

Stereo Select Mode – Two selectable stereo sources can be played in stereo in a single output zone. Volume control and source selection are available in the zone.

The auxiliary output can be used with all three modes of operation. Two user interfaces, volume control and volume control with A/B select, are available for operation from remote locations.

Bose DXA2120 Features:

  • Six inputs: four mic/line inputs with choice of balanced Euroblock or unbalanced RCA connectors, one page input and one direct input
  • Two powered outputs that can operate at high or low impedance: 2 x 120 Wat 4 ohms or 2 x 100 W at 70/100V
  • Three operating modes for greater flexibility in installed music or speech applications: Mixer Mode, Dual Mono Select Mode, and Stereo Select Mode
  • Easy setup and control via onboard controls – no computer needed
  • DSP includes loudspeaker EQs and dynamic EQ functions engineered specifically for Bose loudspeakers
  • Opti-voice® paging provides a smooth transition between music and announcements
  • 24-volt DC backup power connection for added reliability and integration onto fire and evacuation systems
