Crown 14M Architectural & Engineering Specifications
Add to My manuals1 Pages
Crown 14M is a 4-input, 1-output commercial and industrial audio mixer with a host of features for professional audio applications. With its versatile input options, including balanced mic and line inputs as well as RCA connectors, and a wide range of output level controls, it provides precise audio mixing capabilities. The tone controls on each input channel allow for precise sound shaping, while the clip indicator helps prevent distortion.

14M shall be a mixer for commercial and industrial audio. It has 4 inputs and 1 output channel.
Specifi cations
The 14M shall have the following specifi cations:
Frequency Response (at line out, 20 Hz to 20 kHz): +/– 1 dB. Signal to
Noise Ratio (master volume at minimum): 100 dB. THD: 0.05% typical with 800 mV input, 1V output. Input Sensitivity (for full output at maximum gain): Balanced mic inputs 3 mV, balanced line inputs 800 mV,
RCA connectors 400 mV. Input Impedance (nominal): Mic 400 ohms, line
100 kilohms, RCA 50 kilohms. Crosstalk (all controls at "10"): –70dB at
1kHz. Line Output Level (nominal): 1.2 V into 10 kilohms. Phantom Power:
15 VDC. AC Line Voltages Available: 100V 50/60 Hz, 120V 60 Hz, 220V
50/60 Hz, 230V 50/60 Hz, 240V 50/60 Hz. Operating Temperature/Humidity: 0 degrees C to 40 degrees C at 95% relative humidity (non-condensing). Storage Temperature: –20 degrees C to 85 degrees C.
Front Panel Controls and Indicators
Front panel controls and indicators shall include the following:
Power Switch: Pushbutton on-off switch. The power switch shall not affect the 24V DC auxiliary power input. Input Volume Controls: four microphone/line, detented potentiometers with knobs. Output Volume Controls:
One detented potentiometer with knob. 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 input channel, illuminates when input signal exceeds 100 mV. Clip Indicator:
Red LED illuminates at threshold of audible distortion.
Architectural & Engineering Specifi cations
Rear Panel Controls and Connectors
Rear panel controls and connectors shall include the following:
Fuse: protects the power supply. 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. Mixer Confi g Switch: A DIP switch with two functions which shall be 1. Assign 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, shall not affect RCA inputs. Priority Connector: 3-pin Phoenixtype connector shall allow Input 1 to mute other input signals by contact closure. Input Routing Switch: DIP switches shall assign each input signal to each output, two switches per input. Line Out Connector: One 3-pin balanced Phoenix-type connector; level controlled by master volume control.
Input Connectors shall include a Mic/Line Connector of 3-pin Phoenixtype, balanced, one per input channel, and a dual RCA Input Connector for stereo music signals, unbalanced, summed together, two connectors per input channel. Mic/line Switch: Selects mic-level or line-level signals, one switch for each balanced input.
Miscellaneous
Included accessories shall be a power cord, detachable rack ears, Phoenixtype connectors, and spade lugs.
The dimensions of the mixer shall allow for 19 inch (48.3 cm) EIA standard
(RS-310-B) rack mounting. The mixer shall be 3.5 inches (8.9 cm) high, and 14 inches (35.6 cm) deep behind the rack-mounting surface.
The mixer shall weigh 8.7 lb (3.9 kg).
The mixer shall be designated the Crown 14M.
