6 Russound A2100 Installation Manual
The A2100 can be used in a side-by-side conguration using the optional rack
mounting kit. This feature makes it easy to add amplication to two controllers
or two zones (e.g., on the MCA-88 controller).
Another popular application is to use 2 A2100 ampliers in Bridged Mode,
each using one channel of a stereo signal, for a powerful 225 watts per channel
@8 ohms.
The example shown shows three A2100 units being used to add amplication
