It offers Class-D amplifiers with 1, 2, and 4 channels, delivering RMS power of 120W, 240W, and 350W. Each channel is independent and has its own line transformer, allowing for selection between 70\/100V operation or low impedance between 4-16 ohms for each, offering maximum versatility depending on the needs of each zone. Each channel is equipped with a volume control, LED VU-meter, clip indicator, and gain adjustment via a trimmer on the rear panel. A high-pass filter with a cutoff frequency of 400Hz is also present. Input and output connections are all balanced with XLR connectors; power outputs are on Phoenix (Europlug) connectors. The 1 and 2-channel versions also feature auxiliary 24V DC power for emergency auxiliary lines. Helvia has paid great attention to the safety, reliability, and durability of these amplifiers. Each channel is equipped with a power-on mute system, signal limiter, thermal protection, and current limiting. The cooling system with a temperature-controlled fan is enhanced by the standard 2U 19\" rack format, which promotes thermal dissipation. Quality is based not only on the selection of active and passive components but also on the quality of materials used in the line transformers and the use of digital processing to offer stability, reliability, and high-level audio performance.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003e4 Channels, 350W Power each\u003c\/li\u003e\n\n\u003cli\u003e70V\/100V and 4-16ohm Operation\u003c\/li\u003e\n\n\u003cli\u003e2U 19\" Rack for maximum heat dissipation\u003c\/li\u003e\n\n\u003cli\u003eHigh-quality components for maximum reliability\u003c\/li\u003e\n\n\u003cli\u003eComprehensive protection system including signal limiter, thermal protection, and current limiting\u003c\/li\u003e\n\n\u003cli\u003eVariable speed fans for quiet and efficient cooling\u003c\/li\u003e\n\n\u003cli\u003eRMS Power at 100V: 4x350W\u003c\/li\u003e\n\n\u003cli\u003eRMS Power at 70V: 4x350W\u003c\/li\u003e\n\n\u003cli\u003eRMS Power 4-16O: 4x350W @ 4O\u003c\/li\u003e\n\n\u003cli\u003eInput Sensitivity: 1V\/Gain max @ 0.775V\u003c\/li\u003e\n\n\u003cli\u003eInput Impedance: 20KO ±10%\u003c\/li\u003e\n\n\u003cli\u003eHigh-Pass Filter: ON = 400Hz-20kHz; OFF = 80-20kHz\u003c\/li\u003e\n\n\u003cli\u003eFrequency Response: 80-20kHz\/ 400Hz-20kHz\u003c\/li\u003e\n\n\u003cli\u003eTHD (1W @ 1KHZ): \u0026lt; 0.05%\u003c\/li\u003e\n\n\u003cli\u003eDamping Factor: \u0026gt;300 @ 100 Hz\u003c\/li\u003e\n\n\u003cli\u003eCrosstalk: \u0026gt;70dB\u003c\/li\u003e\n\n\u003cli\u003eS\/N Ratio: \u0026gt;85dB\u003c\/li\u003e\n\n\u003cli\u003eAmplifier Class: Class D\u003c\/li\u003e\n\n\u003cli\u003ePower Supply: AC 230V\u003c\/li\u003e\n\n\u003cli\u003ePower Consumption (Average): 1760W\u003c\/li\u003e\n\n\u003cli\u003eInput Connectors: XLR 3-Pin Female\u003c\/li\u003e\n\n\u003cli\u003eOutput Connectors: Phoenix 5-Pin\u003c\/li\u003e\n\n\u003cli\u003eChannel Link Connectors: XLR 3-Pin Male\u003c\/li\u003e\n\n\u003cli\u003eCooling: Temperature-Controlled Fan\u003c\/li\u003e\n\n\u003cli\u003eDimensions (WxDxH): 484x400x88 mm (19.0 x 15.7 x 3.5 in)\u003c\/li\u003e\n\n\u003cli\u003eRack Mount: 2x 19\" Rack Units\u003c\/li\u003e\n\n\u003cli\u003ePacking Dimensions (WxDxH): 550 x 500 x 170 mm (21.6 x  19.7 x 6.7 in)\u003c\/li\u003e\n\n\u003cli\u003eNet Weight: 20.0 kg (44.1 lbs.)\u003c\/li\u003e\n\n\u003cli\u003eGross Weight: 21.6 kg (47.7 lbs.)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"HELVIA","offers":[{"title":"Default Title","offer_id":53993205989709,"sku":"HLV0009","price":1375.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/183296-large_default.jpg?v=1779915004","url":"https:\/\/musicdelivery.net\/en\/products\/helvia-zeus-4350ca-amplificatore-di-potenza-4x350w","provider":"Music Delivery","version":"1.0","type":"link"}
