6.0 User Interfaces
6.1 User interface use
Bose has designed two user interface 
 
controls for use with the FreeSpace
®
 
 
DXA 2120 Digital Mixer/Amplifier. 
• Bose volume control user interface
 
is for use when only volume control is 
required.
• Bose volume control with A/B select 
user interface is for use in Stereo Select 
Mode or Dual Mono Select Mode when 
an output provides audio from more than 
one input source. 
Connection of one or two user interfaces to the chassis disables 
the output gain knob for the output assigned to that user 
 
interface.
6.1.1 Mode user interface requirements
• For Mixer Mode: 
 
Sources can be routed to either or both outputs. Use of one or 
two volume control user interfaces is optional. No user inter-
faces are required.
• For Stereo Select Mode:
 
Source routing is fixed. This mode supports the use of one user 
interface in a single zone. Use the volume control with A/B 
select user interface.
• For Dual Mono Select Mode:
 
Source routing is fixed. This mode supports the use of one user 
interface for each output channel. Use two volume controls 
with A/B select user interfaces.
