Crown 160WATT 4 INPUT Comm Mixer/Amp - 160 Watt, 4 Input Business Music Mixer Amplifier

The Crown® 180MA, 280MA and 1160MA are high-value mixer-amplifi ers for commercial and industrial audio. They provide 4-ohm and constant-voltage outputs (70V and 100V). 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 mixer-amps vary in their number of inputs, number of outputs, and power range:

• 1160MA has 4 inputs and one 160W power amplifier for single-zone systems.

Input routing allows each input to be assigned to any output. This drastically reduces the need for

additional mixers or amplifi ers (or both) when systems require either more inputs or outputs.

However, each mixer-amplifi er 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. Other features include priority muting, phantom power, four-tone generator, and capability for remote volume control.
