Compact Amplifier for Retail Speaker Demonstrations

The Audio Authority® 1805 is a compact amplifier designed to provide amplification for speakers in retail demonstrations. Volume may be controlled via RS-232 or RS-485 using custom control devices such as a touch screen or capacitive touch panel. For best results use a commercial grade analog media player such as the Model 1803 or a BrightSign® media player. 


  • Compact footprint for easy placement inside store fixture
  • Easy connection to media players such as BrightSign media players, or Audio Authority 1803 
  • Control with RS-232 commands from any serial controller
  • Control volume with custom touch panel, touchscreen, or other user interface


Measurements with an 8 ohm load, both channels driven:
