This clear philosophy ensures that each model provides exactly what you need, and nothing extra.\u003cbr\u003e\n\u003cbr\u003e\nThe Amplify series comes in three different versions: DIRECT, X-OVER, and DSP (the DSP model will be available in summer 2025).\u003cbr\u003e\n\u003cbr\u003e\nX-OVER models are the ideal choice for traditional installations in cars using either factory or aftermarket head units. These amplifiers feature, among other things, a speaker-level input and extensive crossovers.\u003cbr\u003e\n\u003cbr\u003e\nThe signal in DIRECT models does not have to pass through crossover circuits, which allows for better sound quality and more precise adjustments. These amplifiers are intended for systems with a separate DSP device. As their name suggests, DIRECT series amplifiers have no crossovers at all; all adjustments are made with a separate DSP device.\u003cbr\u003e\n\u003cbr\u003e\nThe 2-Series is the most affordable line in the AMPLIFY series, still offering extensive features and incredible sound quality in a compact size.\u003cbr\u003e\n\u003cbr\u003e\nThe extensive crossovers of the X-OVER model amplifiers can be switched off if necessary, and adjustments can be made from the head unit or a separate DSP device. The signal can be fed to the device via RCA or speaker level, and the device will automatically turn on if needed (auto remote On \/ Off).\u003cbr\u003e\n\u003cbr\u003e\nThe Amplify 2-Series brings out every nuance of sound, exceeding expectations in its price range in both sound quality and power.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTekniset tiedot:\u003c\/strong\u003e\u003cbr\u003eTechnical data:\u003cbr\u003e\n\u003cbr\u003e\nPower RMS  ≤ 1% THD+N @ 14.4 V\t \u003cbr\u003e\n- @ 4 Ohms\t4 x 100 Watts \u003cbr\u003e\n- @ 2 Ohms\t4 x 190 Watts \u003cbr\u003e\n- @ 1 Ohm\t-\u003cbr\u003e\n- bridged @ 4 Ohms\t2 x 380 Watts\u003cbr\u003e\n- bridged @ 2 Ohms\t- \u003cbr\u003e\nMax. output power per channel*\tUp to 240 Watts RMS @ 2 Ohms\u003cbr\u003e\nAmplifier technology\tClass D\u003cbr\u003e\nInputs\t4 x RCA \/ Cinch\u003cbr\u003e\n1 x Remote In\u003cbr\u003e\nInput sensitivity\t1 - 8 Volts\u003cbr\u003e\nInput impedance\t67 kOhms\u003cbr\u003e\nOutputs\t4 x Speaker output\u003cbr\u003e\nOutput voltage RCA \/ Cinch\t- \u003cbr\u003e\nSignal converter for digital input\t- \u003cbr\u003e\nFrequency response\t10 Hz - 20.000 Hz\u003cbr\u003e\nBass boost\t- \u003cbr\u003e\nHighpass\t-\u003cbr\u003e\nLowpass\t-\u003cbr\u003e\nBandpass\t-\u003cbr\u003e\nSubsonic\t- \u003cbr\u003e\nPhase\t- \u003cbr\u003e\nSlope high- \/ lowpass\t-\u003cbr\u003e\nSlope subsonic \t-\u003cbr\u003e\nSlope subsonic \/ lowpass\t- \u003cbr\u003e\nSignal-to-noise ratio (A-weighted)\t99 dB @ full power\u003cbr\u003e\nDistortion (THD @ 1 kHz, 1 W into 4 Ohms)\t 0.012%\u003cbr\u003e\nDistortion (THD+N @ 1 kHz, 1 W into 4 Ohms)\t 0.02 %\u003cbr\u003e\nDistortion (THD @ 100 Hz, 1 W into 4 Ohms)\t-\u003cbr\u003e\nDistortion (THD+N @ 100 Hz, 1 W into 4 Ohms)\t-\u003cbr\u003e\nDamping factor\t70\u003cbr\u003e\nOperating voltage\t10.5 - 16 Volts (max. 5 sec. down to 6 Volts)\u003cbr\u003e\nIdle current\t1,100 mA\u003cbr\u003e\nFuse\t2 x 30 A LP-Mini-fuse (APS)\u003cbr\u003e\nPower rating\tDC 12 V ⎓ 70 A max.\u003cbr\u003e\nOperating temperature range\t-40 °C to +70 °C\u003cbr\u003e\nAdditional features\tStart-Stop capability, Clipping LED, DirectDSP inputs\u003cbr\u003e\nDimensions (H x W x D)\t40 x 248 x 114 mm \/\u003cbr\u003e\n1.58 x 9.76 x 4.49\"\u003cbr\u003e\n * One channel driven (≤ 10 % THD+N @ 14.4 V)\u003cbr\u003e\n\u003cbr\u003e\n \u003cbr\u003e\n\u003cbr\u003e\nScope of delivery:\u003cbr\u003e\n1 x Amplifier HELIX AMPLIFY 204 DIRECT\u003cbr\u003e\n2 x Allen key\u003cbr\u003e\n1 x Mounting material\u003cbr\u003e\n1 x Connection cable\u003cbr\u003e\n2 x Fuse\u003cbr\u003e\n1 x Instruction manual\u003cbr\u003e\u003cbr\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":56759804789111,"sku":"AMPLIFY 204 DIRECT","price":239.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/AMPLIFY-204-DIRECT-Perspective-10-01-2026.jpg?v=1771440571","url":"https:\/\/hifikaupat.fi\/en\/products\/helix-amplify-204-direct","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
