Introduction 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 1703.
How to Set the Model 1805 Amplifier Gain Controls • Raise the source volume controls (if present) to maximum. • Turn the 1805 gain dials (left and right channels) to 1 and start the audio source playing. • Select a speaker position, and raise the 1805 gain dials to the point of distortion, then reduce to the desired maximum level.
• Connect power supply to AC power, then to the power port. • Adjust gain (see page 3). • Call Audio Authority with questions that are not addressed in this manual. 2048 Mercer Road, Lexington, KY 40511-1071 USA 800-322-8346 • 859-233-4599 • Fax: 859-233-4510 support@audioauthority.com •...
