Performance

Frequency Reponse (at 1 watt from 4-ohm tap): 70 Hz to 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.

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/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. 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 chan- nel. 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 chan- nel. Illuminates at threshold of audible distor- tion. Does not respond to signals from the AMP INPUT connector.

Output Volume Controls: One per output chan- nel. 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-pinPhoenix-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 connec- tor allows Input 1 or Input 5 (280MA only) to mute other input signals by contact closure.

Input Routing Switch (280MA only): DIP switches that assign each input signal to each output. Two switches per input.

Line Out Connector: One 3-pin balanced Phoe- nix-type connector per output channel. Post master, pre-VCA. Level controlled by master volume control.

The tone generator has been omitted. Call Crown Tech Support if you have a tone genera- tor question.

Input Connectors:

Mic/Line Connector: 3-pin Phoenix-type, bal- anced, 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 amplifer channel. 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 signals. One switch for each balanced input.

Link In/Out Switch: Slide switch, one per chan- nel. 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.
