The JBL Crown 280A 2x80W Power Amplifier with 70/100V is a high-value amplifier for commercial and industrial audio. They provide 4-ohms and constant-voltage outputs (70V and 100V). The amps are part of Crown's Commercial Audio Series, which also includes mixers and mixeramps. These low-cost units provide all necessary features in a simple building-block format. The amplifiers vary in their number of inputs, number of outputs and power range. The 1160A has 1 input and one 160W power amplifier for single-zone systems.

Some applications include schools, hospitals, factories, restaurant/retail, houses of worship, fitness facilities, A/V boardrooms, prisons and small offices. Typical uses are paging, background music, security and evacuation instructions. The sound system can be upgraded as a facility expands. For example, you can add more mixers for more inputs or add more power amps (or mixer-amps) to handle more zones.
