6. INTRODUCTION Thank you for purchasing the AS2 AS2 S Automatic Speaker Source Selector The AS2 and AS2 S automatically switch a single pair of speakers between two speaker level stereo sources a main source connected to the Input A terminals and a remote source connected to the Input B terminals When the AS2 senses a remote source signal present at the Input B terminals that source signal is automatically switched through to the output terminals When the remote source signal is no longer present on Input B after a short installer adjustable time delay the AS2 and AS2 S automatically switch the outputs to the main source connected to the Input A terminals The time it takes the AS2 and AS2 S to switch back to Input A from Input B can be adjusted to suit the different types of audio sources being used or the preferences of the listeners The sensitivity of the detection switching circuitry is also adjustable to work with a variety of audio source equipment APPLICATIONS INSTRUCTION MANUAL AS2 and AS2 S INDUSTRY UPGRADE AUTOMATIC SECONDARY SPEAKER SOURCE SELECTOR AS2 and AS2 S NEW FEATURES The AS2 and AS2 S incorporate several new features that improve their performance and installability e The AS2 operates on a single output 12V DC power supply and can also be pow ered directly by 12V sources in cars boats or RV installations The AS2 power inputs have reverse polarity protection e The AS2 features DC In and DC Out
