Crown 1160-A, 180-A, 280-A, 660-A Brochure

180A 280A 1160A 660A
he Crown
are high-value amplifi ers for commercial and
T
industrial audio. They provide 4-ohm and constant-voltage outputs (70V and 100V). The 660A, a six-channel amplifi er, provides 4-ohm and constant-voltage outputs (70V and 100V) on channels 1 through 4, and 4-ohm outpus on channels 5 and 6. The 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.
The amplifi ers vary in their number of inputs, number of outputs, and power range:
• 180A has 1 input and one 80W power amplifi er for single-zone systems.
• 280A has 2 inputs and dual 80W power ampli­fi ers for two-zone systems.
• 1160A has 1 input and one 160W power ampli­fi er for single-zone systems.
• 660A has six inputs and six 60W power ampli­fi er channels for multi-zone systems. It can drive different types of speakers in different areas of a facility.
Some applications include schools, hospitals, factories, restaurant/retail, houses of worship, fi tness facilities, A/V boardrooms, prisons, and small offi ces. 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.
