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.
