The ADP-1.2 Adapter provides a convenient way to adjust a stereo speaker-level signal to line level. This line-level signal can then be fed to an amplifier or other audio device.

The ADP-1.2 is particularly useful for taking the amplified output of a multiroom controller and feeding the signal into a more powerful amplifier to provide more volume. It can also be used to feed into a second amplifier to accommodate more speakers.
