MAD A1 amplifiers have been developed for a long time and have been improved even more than their predecessor. The end result is truly successful!\u003cbr\u003e First, the aggressive cooling profile keeps the amplifier temperatures under control, even when you push it with a heavy hand. You can forget about thermal issues and focus on listening to music, as overheating of the amplifier can be left to other device manufacturers.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e \u003cem\u003e\u003cstrong\u003eBetter sound quality than ever before\u003c\/strong\u003e\u003c\/em\u003e \u003cbr\u003eThe inside of the device is not overshadowed by the exterior.

You can control two separate sets with the amplifier, for example, with the separate sets' own crossover filters. Or alternatively, use one channel pair of the amplifier to control the mids and the other channel pair to control the trebles actively, using the amplifier's 12dB high- and low-pass filters.\u003cbr\u003e The amplifier also has its own clip lights for both channel pairs, which light up if the playback exceeds one percent distortion. \u003cbr\u003eIn addition to the RCA input, the amplifier also has a speaker-level input that does not require a wake-up, but the amplifier turns on automatically when it receives a signal, and an RCA output from which you can take the signal to the next amplifier.\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Class AB four-channel amplifier\u003c\/li\u003e\n\n\u003cli\u003e 4 x 75W (4 ohms)\u003c\/li\u003e\n\n\u003cli\u003e 4 x 105W (2 ohms)\u003c\/li\u003e\n\n\u003cli\u003e 2 x 220W (4 ohm, bridged)\u003c\/li\u003e\n\n\u003cli\u003e Frequency range: 15Hz – 22kHz\u003c\/li\u003e\n\n\u003cli\u003e Crossover Filters (Channels 1\u0026amp;2 and 3\u0026amp;4): Off \/ Low Pass \/ High Pass\u003c\/li\u003e\n\n\u003cli\u003e Separate crossover filters for both channel pairs\u003c\/li\u003e\n\n\u003cli\u003e Low-pass filter (12dB\/ok): 50 – 4000Hz\u003c\/li\u003e\n\n\u003cli\u003e High-pass filter (12dB\/ok): 50 – 4000Hz\u003c\/li\u003e\n\n\u003cli\u003e Subsonic: No\u003c\/li\u003e\n\n\u003cli\u003e Signal-to-noise ratio: \u0026gt;98dB\u003c\/li\u003e\n\n\u003cli\u003e Bass EQ (channels 1 \u0026amp; 2): 0 – 12dB @ 45Hz\u003c\/li\u003e\n\n\u003cli\u003e Bass EQ (channels 3 \u0026amp; 4): 0 – 12dB @ 45Hz\u003c\/li\u003e\n\n\u003cli\u003e Phase reversal: No\u003c\/li\u003e\n\n\u003cli\u003e Input sensitivity adjustment: 0.5 – 6V\u003c\/li\u003e\n\n\u003cli\u003e Damping coefficient: \u0026gt;130\u003c\/li\u003e\n\n\u003cli\u003e RCA input: Yes\u003c\/li\u003e\n\n\u003cli\u003e Speaker level input: Yes (with autostart)\u003c\/li\u003e\n\n\u003cli\u003e Wired level control: No\u003c\/li\u003e\n\n\u003cli\u003e Amplifier clip light: Yes (one for each channel pair)\u003c\/li\u003e\n\n\u003cli\u003e Recommended power\/ground wire: 20mm²\u003c\/li\u003e\n\n \u003cli\u003eRecommended speaker cable: 1.5 – 4.0mm²\u003c\/li\u003e\n\n\u003cli\u003e Dimensions: 312 x 209 x 55mm\u003c\/li\u003e\n\n\u003cli\u003e Comprehensive and clear English \u003ca href=\"https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/05\/900MADA1702.pdf\"\u003euser manual\u003c\/a\u003e \n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" srcset=\"https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama.jpeg 1000w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-300x300.jpeg 300w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-150x150.jpeg 150w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-768x768.jpeg 768w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-34x34.jpeg 34w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-670x670.jpeg 670w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-600x600.jpeg 600w, https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama-100x100.jpeg 100w\" sizes=\"(max-width: 250px) 100vw, 250px\" src=\"https:\/\/audiohellman.fi\/wp-content\/uploads\/2023\/03\/gas-mad-naama.jpeg\" class=\"alignnone wp-image-8080\" width=\"250\" height=\"250\"\u003e\u003c\/p\u003e","brand":"GAS","offers":[{"title":"Default Title","offer_id":56759099490679,"sku":"900MADA1704","price":129.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/GAS_MAD_A1-70.4_e5e476b5-8e4a-466f-8e3b-1ccf3173bd60.jpg?v=1771441819","url":"https:\/\/hifikaupat.fi\/en\/products\/gas-mad-a1-70-4","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
