280A has 2 inputs and dual 80W power amplifiers for two-zone systems.

High-value amplifiers for commercial and industrial audio. Provides 4-ohm and constant-voltage outputs (70V and 100V). These amps are part of Crown’s Commercial Audio Series, which also includes mixers and mixer-amps. These low-cost units provide all necessary features in a simple building-block format.
