The Sonance AL2 automatically switches between two line level stereo sources eg a radio tuner and an iPod dock with the output going to an amplifier. The main source, say the radio, is connected to the Input A jacks and the secondary remote source, say the iPod dock, is connected to the Input B jacks. The output is connected to the amplifier.
Please note this product is currently on week back order – delivery date is anticipated to be June 2018.
In normal mode the radio would always play through the ampifier, but when the AL2 senses a signal present at the Input B jacks, say by an iPod being plugged into the dock and turned on, the iPod music is automatically switched through to the amplifier on the output jacks. When the iPod signal is no longer present on Input B, after a short time delay, the AL2 automatically switches the outputs back to the main (radio) source connected to Input A. Using this system multiple sources can be cascaded automatically to play without any selection required by the user.
LEDs indicate the active input. The time it takes the AL2 to switch back to Input A from Input B can be adjusted. The sensitivity of the detection/switching circuitry is also adjustable to work with a variety of audio source equipment. Recessed mounting holes allow wall mounting. The package includes a 12V power supply.
