Architectural & Engineering Specifi cations

COMMERCIAL AUDIO SERIES

14M

The Crown

®

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% typi-

cal 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/Humid-

ity: 0 degrees C to 40 degrees C at 95% relative humidity (non-condens-

ing). 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 micro-

phone/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.

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 Phoenix-

type 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 bal-

anced Phoenix-type connector; level controlled by master volume control.

Input Connectors shall include a Mic/Line Connector of 3-pin Phoenix-

type, 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, Phoenix-

type 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.
