Crown 1160a User Guide

The Crown

®

 180A, 280A, 1160A and 66A are 

high-value amplifiers for commercial and 
industrial audio. They provide 4-ohm and con-
stant-voltage outputs (70V and 100V). The 
660A, a six-channel amplifier, provides 4-ohm 
and constant-voltage outputs (70V and 100V) 
on channels 1 through 4, and 4-ohm outputs 
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.

Some applications include schools, hospitals, 
factories, restaurant/retail, houses of worship, 
fitness facilities, A/V boardrooms, prisons, and 
small offices. Typical uses are paging, back-
ground music, security and evacuation instruc-
tions. 

.The amplifiers vary in their number of inputs, 
number of outputs, and power range:

• 180A has 1 input and one 80W power ampli-
fier for single-zone systems.

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

• 1160A has 1 input and one 160W power 
amplifier for single-zone systems.

• 660A has six inputs and six 60W power 
amplifier channels for multi-zone systems. It 
can drive different types of speakers in different 
areas of a facility.

The sound system can be upgraded as a facility 
expands. For example, you can add more mix-
ers for more inputs, or add more power amps 
(or mixer-amps) to handle more zones.

• 180A, 280A and 1160A have1 or 2 inputs, 1 
or 2 amplifier output channels. 660A has 6 
inputs and 6 amplifier output channels.

• Ideal for commercial and industrial use

• Expandable by adding Crown Commercial 
Audio mixers or Commercial Audio mixer-
amplifiers

• Balanced Phoenix-type line inputs; touch-
proofed screw-terminal speaker outputs

• Advanced protection system includes output 
current limiting, DC protection, circuit breaker/
fuse, and thermal protection. Details available
