Crown MA12000I MacroTech Power Amplifier

Patented, cutting-edge Class-I circuitry gets more power out of an amplifier with less wasteRugged construction ensures that all Macro-Techs are built to withstand years of abuse on the roadGlobal Power Supply designed to deliver maximum power no matter what country you work inBuilt-in load, line voltage, input and output monitoringStandard Ethernet networking via System Architect lets system operators monitor and control the amplifier from any locationPerformance Frequency Response (at 1 watt, 20Hz - 20 kHz into 8 ohms) 0.25 dB Signal to Noise Ratio below rated full-bandwidth power, A-weighted > 108 dB Total Harmonic Distortion (THD) at 1 watt into 8 ohms <0.1% Total Harmonic Distortion (THD) Plus Noise at full rated power < 0.35%, 20 Hz to 20 kHz Intermodulation Distortion (IMD) 60 Hz and 7 kHz at 4:1, from full rated output to -30 dB < 0.35% Damping Factor (20 Hz to 100 Hz at 8 ohms) > 5000 Crosstalk (below rated power, 20 Hz to 1 kHz) > 80 dB Common Mode Rejection (CMR) (20 Hz to 1 kHz) > 55 dB, typically > 70 dB DC Output Offset (Shorted input) < 3 mV Input Impedance (nominal) 10 kilohms balanced, 5 kilohms unbalanced Maximum Input Level +20 dBu typical Load Impedance (Note: Safe with all types of loads) Stereo: 1/2/4/8/16 ohms Bridge Mono: 2/4/8 ohms Input Sensitivity (referenced to 8 ohm rated output)1.4V, 32 dB gain, and 26 dB gain Voltage Gain (referenced to 8 ohm rated output)MAi-12000i: 39.3 dB to 24.5 dB Required AC Mains Universal AC input, 100-240VAC 50/60 Hz (15%). Maximum AC mains voltage 264VAC. AC Line Connector Five cordsets supplied with amplifier (USA, UK, European, Australia, India) Construction Cooling Dual-zone, microprocessor controlled, continuously variable speed fans, front-to-back airflow Front Panel Cast aluminum with integrated handles. Weight 28 pounds (12.7 kg) net, 36 pounds (16.3 kg shipping. Dimensions (W x H x D) 19 in. (48.3 cm) W x 3.5 in. (8.9 cm) H x 16.2 in. (41.1 cm) D. Protection Amplifier is protected against reactive loads, faults and shorts. If one channel experiences a catastrophic failure, the entire amplifier will shut down. Guaranteed minimum power in watts at 20 Hz-20 kHz with 0.35% THD. 5,900W (20 mS burst, 2-ohm dual per ch.), 3,500W (20 Hz-20 kHz, 2-ohm dual per ch.), 3,500W (1 kHz, 2-ohm dual per ch.) 4,000W (4-ohm dual per ch.) 2,100W (8-ohm dual per ch.) 7,000W (4-ohm bridge) 8,000W (8-ohm bridge)
