Product Overview

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.

Product Information

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 13-pin Euroblock
connectors or dual RCAjacks.

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
AlB select, are available for operation from remote locations.
