The amp  can operate in stereo, parallel mono, or bridged mono modes for terrific versatility. It features XLR and 1\/4\" inputs, and Speakon and binding post outputs, allowing you to connect to a variety of sound systems. Each channel features an input gain control and LED indicators for signal, overload, and fault.\u003cbr\u003e\n \u003cbr\u003e\nThe amp  has a pair of variable-speed cooling fans with front-to-rear airflow for smooth, reliable operation. For further protection and reliability, the amplifier  offers circuitry that protects against short circuits, open circuits, overheating, and more. It also has a ground-lift switch to prevent hum caused by ground loops. A voltage selector switch lets you choose between 110\/220V operation for use anywhere in the world.\u003cbr\u003e\n \u003cbr\u003e\nFeatures\u003c\/p\u003e\n\n\u003cp\u003e• Rackmount design can be installed in any standard equipment rack\u003cbr\u003e\n• Can operate in stereo, parallel mono, or bridged mono modes\u003cbr\u003e\n• XLR and 1\/4\" inputs, along with Speakon and binding post outputs for versatile connectivity\u003cbr\u003e\n• High-quality Class AB output circuitry\u003cbr\u003e\n• Input level controls on each channel\u003cbr\u003e\n• Integrated compressor prevents distortion\u003cbr\u003e\n• LED indicators for power, signal, clip, and protect\u003cbr\u003e\n• Pair of variable-speed cooling fans with front-to-rear airflow for reliable operation\u003cbr\u003e\n• Integrated protection circuitry for full short circuit, open circuit, thermal, soft start, DC voltage, Sub Electronic and RF protection\u003cbr\u003e\n• Ground-lift switch reduces hum\u003cbr\u003e\n• Selectable operating voltage for worldwide use\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\n\u003cp\u003e• Power Rating\u003cbr\u003e\n• Output Power 8 (ohms): 2 x 800W\u003cbr\u003e\n• Output Power 4 (ohms): 2 x 1300W\u003cbr\u003e\n• Output Power 2 (ohms): 2 x 1500W\u003cbr\u003e\n• Output Power BRIDGE 8 (ohms): 2000W\u003cbr\u003e\n• Output Power BRIDGE 4 (ohms): 4000W\u003c\/p\u003e\n\n\u003cp\u003e• Frequency Response @ Half Power: 15Hz - 25KHz (+0\/-1dB)\u003cbr\u003e\n• THD+Noise at 1KHz Full Power:\u003cbr\u003e\n• IMD 60Hz \u0026amp; 7KHz, 4:1:\u003cbr\u003e\n• Signal to Noise Ratio: \u0026gt;102dB\u003cbr\u003e\n• Slew Rate (Input Filter Limited): 40V\/uS\u003cbr\u003e\n• Damping Factor 1KHz@8 ohm: \u0026gt;400:1\u003cbr\u003e\n• Input Sensitivity: Selectable (0.77V \/ 1.0V \/ 1.44V)\u003cbr\u003e\n• Input Impedance: 10k ohm Balanced to ground\u003cbr\u003e\n• Input Connectors: Female XLR-3 \u0026amp; 6.35mm TRS Jack\u003cbr\u003e\n• Output Circuit Type: Class AB\u003cbr\u003e\n• Output Connectors: 4 Pole Speakon \u0026amp; Binding Post\u003cbr\u003e\n• Protection:Full short-circuit, Open circuit, Thermal, Soft-start, DC voltage, Sub\/Ultrasonic, RF\u003cbr\u003e\n• LED Indicators (per channel): Bridge, Parallel, Power, Signal, Clip, Protect\u003cbr\u003e\n• Panel Controls: Front-2 input attenuators REAR Ground lift, mode selection, compressor\u003cbr\u003e\n• Cooling: Front-to-Back via 2 variable speed fans\u003cbr\u003e\n• Indicators: Power: 1 x Blue LED, Signal: 2 x Green LED, Clip : 2 x Red LED, Protect: 1 x Red LED\u003cbr\u003e\n• Power Supply Voltage: Voltage selectable 110 \/ 220V AC\u003cbr\u003e\n• Power Supply Voltage: Voltage selectable: 110V \\ 220V AC\u003cbr\u003e\n• Power supply fuse (250): 10A\u003cbr\u003e\n• Dimensions: 19 W x 18.7 L x 4 H inches\u003c\/p\u003e","brand":"Marathon","offers":[{"title":"Default Title","offer_id":58451475693832,"sku":"MA-4050","price":419.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1057\/4076\/3400\/files\/img_proxy_793537b6-41f9-4cf2-8c23-f42c0b7fb608.jpg?v=1786933190","url":"https:\/\/musictoner.shop\/products\/marathon-ma-4050-professional-power-amplifier","provider":"Musictoner","version":"1.0","type":"link"}
