Balanced line inputs: 800 mV.

RCA connectors: 400 mV.

Input Impedance (nominal):

Mic: 400 ohms.

Line: 100 kilohms.

RCA: 50 kilohms.

Crosstalk: –70dB at 1kHz.

Line Output Level (nominal): 1V into 10 kilohms.

Phantom Power: 15 VDC.

AC Line Voltages Available: 120V/60Hz. Line voltage tolerance +15%, –20%.

Operating Temperature/Humidy: 0° C to 40° C at 95% relative humidity (non-condensing).

Storage Temperature: –20° C to 85° C.

Front Panel Controls and Indicators

Power Switch: Pushbutton on-off switch.

Input Volume Controls: Four controls, one per input. Detented potentiometers with knobs.

Tone Controls: Bass and Treble non-detented recessed potentiometer 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 –40 dBu.

Output Signal Presence Indicator: Green LED illuminates when output signal level exceeds 100 mV (45 dB below full power) from the 4-ohm tap.

Clip Indicator: Red LED on output illuminates at threshold of audible distortion.

Master Output Volume Control: Detented potentiometer with knob.

Back Panel Controls, Connectors and Indicators

Reset Switch: Resets the circuit breaker that protects the power supply.

AC Power Inlet: Detachable IEC.

Amplifier Output Connector: 4-position termi- nal strip with COM (Common), 4 ohms, 25V and 70V terminals. Accepts up to 10 AWG terminal forks. Non-touch cover included.

Output VCA Connector: 4-pinPhoenix-type connector for two VCA control lines of +10 VDC and ground. Compatible with Crown 1-VCAP module.

Priority Connector: 3-pinPhoenix-type connec- tor for push-to-talk mic contact closure.

Preamp Line Out Connector: 3-pin balanced Phoenix-type connector. Post master, pre-VCA. Level controlled by master volume control.

MOH 1V Level Control: Trim pot adjusts level for Music-On-Hold 1V output.

MOH 1W Level Control: Trim pot adjusts level for Music-On-Hold 1W output.

MOH SPI Indicator: Flashes when MOH signal is present.

MOH 1V Phoenix Connector: 3-pin Phoenix connector for 1V, 600-ohmtransformer-isolated output.

MOH 1W Phoenix Connector: 3-pin Phoenix connector for 1W output.

MOH 1V RCA Connector: Two mono RCA con- nectors for 1V output (in parallel with 600-ohm connections so they are isolated).

Balanced Input Connector: Detachable 3-pin Phoenix style connector for balanced line-level signals, one each for input channels 2-4.

Balanced Input Connector: Detachable 3-pin Phoenix style connector for balanced mic-levelline-level signals, for input channel 1.

Tel Connector: Transformer-isolated 600-ohm input, summed into Input 1 for paging from a telephone system.

Dual RCA Input Connector: For stereo music signals, unbalanced, summed together, two connectors per input channel.

Amp Input Connector: 3-pinPhoenix-type,high-impedance balanced. Used to link an additional mixer to the mixer-amplifier. Can be used to connect an external processor.

Mic/line Switch: Selects mic-level or line-level signal for Input 1.

Phantom Power Switch: Turns phantom power on or off for Input 1.

VOX Threshold: Trim pot controls how loud the voice must be before ducking occurs. Can be set for no ducking.

Link In/Out Switch: Slide switch. When set to IN, any signal applied to the Amp Input connec- tor will be mixed with the input signal(s). When set to OUT, only the signal from the Amp Input Connector will appear at the amplifier output.

Priority Connector: 3-pin Phoenix-type connec- tor for push-to-talk mic contact closure. Input 1 is the priority input for the amplified output, so Input 1 ducks the other inputs. Threshold of activation depends on input voltage. Ducking does not affect MOH outputs.

Active Indicator: Illuminates when VOX ducking is active.

Cooling

Convection cooled.

Protection

Current Limit Protection: Included.

Thermal Limit Protection: Over-temperature thermal cutout.

DC-Fault Load Protection: Included.

Turn On/Turn Off: No thumps or pops.

COMMERCIAL AUDIO

The Crown® 140MPA is a high-value mixer-amplifier for commercial audio. It provides 4-ohm and constant-voltage outputs (25V and 70V). Typical uses are paging, background music, and music- on-hold. The unit provides 4 inputs (each with a volume control) and a 40W amplifier output. Other features include priority ducking, phantom power, and capability for remote volume control. Multiple

units can be linked.
