Crown 180A Amplifier. The Crown 180A is a high-value amplifier for commercial and industrial audio. It provides 4-ohm and constant-voltage outputs . The amp is 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.Some applications include schools, hospitals, factories, restaurant/retail, houses of worship, fi tness 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 to handle more zones. Designed for commercial and industrial use Ideal for paging, background music 80 watt power amp (4/8 ohm, 25/70v operation) Advanced protection system includes output current limiting, DC protection, circuit breaker/fuse, and thermal protection 3 Year, no-fault, fully transferable warranty Package weight: 26.00lbs Package dimensions: 23.0000"(length) x 18.5000"(width) x 5.5000"(height)
