[제품설명]

The Crown 180MA shall be a mixer-amplifier for commercial and

industrial audio.

It provides 4-ohm and constant-voltage outputs (70V and100V).

The 180MA has 4 inputs and one 80W power amplifier for single-zone systems.

[제품스펙]

The 180MA shall have the following specifi cations:

Minimum guaranteed power into 4 ohms or 70V/100V output: 80W maximum

power at 1 kHz with 0.5% THD. Frequency Reponse (at 1 watt from

4-ohm tap, 70 Hz - 19 kHz): +/- 1 dB. Frequency Response (at line out,

20 Hz to 20 kHz): +/- 1 dB. Power Bandwidth (at 4-ohm tap, 2 dB below

maxium 1 kHz power): 50 Hz to 20 kHz with < 0.5% THD. Signal to Noise

Ratio (ref. to rated power, master volume at minimum): 85 dB. DC Output

Offset: < ±5 mV. THD: Less than 0.5% at rated power at 1 kHz. 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:

–70dB at 1kHz. Line Output Level (nominal): 1V 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. Input Volume Controls: eight

microphone/line, detented potentiometers with knobs. Output Volume

Controls: One per output channel, 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

100 mV (45 dB below full power) from the 4-ohm tap; shall not respond to

signals from the AMP INPUT connector. Output Signal Presence Indicator:

Green LED, one for each input channel, illuminates when input signal

exceeds 100 mV (45 dB below full power) from the 4-ohm tap; shall not

respond to signals from the AMP INPUT connector. Clip Indicators: Red

LED, one per output channel, illuminates at threshold of audible distortion,

shall not respond to signals from the AMP INPUT connector.


Rear Panel Controls and Connectors

Rear panel controls and connectors shall include the following:

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

220/230/240V units shall 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. Amplifi er Outputs

Connectors: One per channel, 4-position terminal strip with Com, 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 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 or Input 5 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 per output channel, post master, pre-VCA,

with level 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 linelevel

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 shall be mixed with the input signal(s). With the Link

Switch OUT, only the signal from the Amp Input Connector shall appear at

the amplifi er output.


Miscellaneous

Cooling shall be by convection. Included protection mechanisms shall

be current limiting, over-temperature thermal cutout, and DC-fault load

protection.

Included accessories shall be a power cord, detachable rack ears, screws

for rack ears, non-touch cover for output connectors, Phoenix-type connectors,

and spade lugs. Optional accessories shall be a 1-VCAP remote

volume control for one channel, and a 4-VCAP remote volume control for

four channels.

The dimensions of the mixer-amplifi er shall allow for 19 inch (48.3 cm)

EIA standard (RS-310-B) rack mounting. The mixer-amplifi er shall be 3.5

inches (8.9 cm) tall, and 12.2 inches (31 cm) deep behind the rack-mounting

surface (not including the non-touch cover).

The mixer-amplifi er shall weigh 21 lb (9.5 kg).

The mixer-amplifi er shall be designated the Crown 180MA.
