Description:
The Crown 180MA, 280MA and 1160MA are high-value mixer-amplifiers 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, fitness facilities, A/V boardrooms, prisons, and small offices. Typical uses are paging, background music, security and evacuation instructions.The 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 amplifiers (or both) when systems require either more inputs or outputs. However, each mixer-amplifier 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.

Front Panel Controls and Indicators:

Power Switch: Push button on-off switch. The power switch does not affect the 24V DC auxiliary power input.
Input Volume Controls: Microphone/line, four in 180MA and 1160MA, eight in 280MA. Detented potentiometers with knobs.
Tone Controls: Bass and Treble non-detented recessed potentiometers on each input channel. Bass ±10 dB at 100 Hz, Treble ±10 dB at 10 kHz.
Power Indicator: Blue LED indicates power on.
Input Signal Presence Indicator: Green LED, one for each input channel, illuminates when input signal exceeds –24 dBu (line) or –70 dBu (mic).
Output Signal Presence Indicator: Green LED, one for each output channel, illuminates when output signal level exceeds 100 mV (45 dB below full power) from the 4-ohm tap. Does not respond to signals from the AMP INPUT connector.
Clip Indicators:
Red LED, one per output channel. Illuminates at threshold of audible distortion. Does not respond to signals from the AMP INPUT connector.
Output Volume Controls: One per output channel. Detented potentiometer with knob.

Back Panel Controls and Connectors:

Reset Switch: Resets the circuit breaker that protects the power supply. 220/230/240V units have a fuse instead.
AC Power Inlet: Detachable IEC.
Auxiliary Power Input: 2-position terminal strip for 24 VDC (±10%) backup power. Accepts up to 14 AWG terminal forks.
Amplifier Outputs Connectors: One per channel,4-position terminal strip with COM (Common), 4 ohms, 70V and 100V terminals. Accepts up to 14 AWG terminal forks. Non-touch cover included.
Output VCA Connector: 4-pin Phoenix-type connector for two VCA control lines of +10 VDC and ground. Compatible with Crown 1-VCAP and 4-VCAP modules.
Amp Config Switch: A DIP switch with two functions:
1. Assigns an input as the priority input for each output, thereby temporarily muting the remaining inputs. Muting is activated by contact closure.
2. Global enable switch for phantom power. Does not affect RCA inputs. Default position is off.
Priority Connector: 3-pin Phoenix-type connector allows Input 1 or Input 5 (280MA only) to mute other input signals by contact closure.
Tone Generator Connector: 5-pin Phoenix-type connector. Tones include Pre-Announce Chime, Bell, Alert Tone, and Evacuate Tone. All tones are activated by contact closures on the connector. Internal jumpers can disable tones in an amplifier channel (excluding Pre-Announce Chime).
Tone Level: One potentiometer per output channel sets the volume of the tones. Tone level (except Pre-Announce Chime) is not affected by output volume controls or VCAs.
Chime Level: Potentiometer sets the Pre- Announce Chime level. The Pre-Announce Chime is mixed with Channel-1 signals, so its level also is affected by the master volume control and VCAs.
Input Connectors:
Mic/Line Connector: 3-pin Phoenix-type, balanced, one per input channel.
Dual RCA Input Connector: For stereo music signals, unbalanced, summed together, two connectors per input channel.
Amp Input Connector: 3-pin Phoenix-type, high impedance balanced, one per amplifier channel. Used to link an additional mixer to the mixer amplifierCan be used to connect an external processor.
Mic/line Switch: Selects mic-level or line-level signals. One switch for each balanced input.
Link In/Out Switch: Slide switch, one per channel.With the Link Switch IN, any signal applied to the Amp Input connector will be mixed with the input signal(s). With the Link Switch OUT, only the signal from the Amp Input Connector will appear
at the amplifier output.
Cooling:Convection cooled.
Protection:
Current Limit Protection: Included.
Thermal Limit Protection: Over-temperature thermal cutout.
DC-Fault Load Protection: Included.

Optional Accessories:
1-VCAP remote volume control for one channel.
4-VCAP remote volume control for four channels.
