This clear philosophy ensures that each model offers exactly what you need, and nothing more.\u003cbr\u003e\n\u003cbr\u003e\n The 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\n X-OVER models are ideal for traditional car installations using either a factory or aftermarket stereo. These amplifiers feature speaker-level input and wide crossovers.\u003cbr\u003e\n\u003cbr\u003e\n The DIRECT models do not need to pass the signal 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 the name suggests, the DIRECT series amplifiers do not have crossover filters at all, but all adjustments are made by a separate DSP device.\u003cbr\u003e\n\u003cbr\u003e \nThe 2-Series is the most affordable model in the AMPLIFY series, yet offers extensive features and incredible sound quality in a compact size.\u003cbr\u003e\n\u003cbr\u003e\n The wide crossover filters of the X-OVER amplifiers can be switched off when needed and adjustments can be made from the player or a separate DSP device. The signal can be fed to the device via RCA or speaker level and the device will wake up automatically if necessary (auto remote On \/ Off).\u003cbr\u003e\n\u003cbr\u003e\n The Amplify 2 Series brings out every nuance of sound, exceeding expectations for its price range in both sound quality and power.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e Technical data\u003cbr\u003e\n Power RMS ≤ 1% THD+N @ 28.8 V\u003cbr\u003e\n - @ 4 Ohms 4 x 100 Watts\u003cbr\u003e\n - @ 2 Ohms 4 x 190 Watts\u003cbr\u003e\n - @ 1 Ohm -\u003cbr\u003e\n - bridged @ 4 Ohms 2 x 380 Watts\u003cbr\u003e\n - bridged @ 2 Ohms -\u003cbr\u003e\n Max. output power per channel* Up to 240 Watts RMS @ 2 Ohms\u003cbr\u003e\n Amplifier technology Class D\u003cbr\u003e\n Inputs 4 x RCA \/ Cinch\u003cbr\u003e\n or\u003cbr\u003e\n 4 x High-level speaker input\u003cbr\u003e\n 1 x Remote In\u003cbr\u003e\n Input sensitivity RCA \/ RCA: 1 - 8 Volts\u003cbr\u003e\n High level: 2 - 16 Volts\u003cbr\u003e\n Input impedance RCA \/ RCA: 8 kOhms\u003cbr\u003e\n High level: 9 - 33 Ohms\u003cbr\u003e \nOutputs 4 x Speaker output\u003cbr\u003e\n Output voltage RCA \/ Cinch -\u003cbr\u003e\n Signal Converter for digital input -\u003cbr\u003e\n Frequency response 10 Hz to 20,000 Hz\u003cbr\u003e\n Bass boost -\u003cbr\u003e\n Highpass 45 Hz - 400 Hz adjustable (can be turned off)\u003cbr\u003e\n Lowpass 45 Hz - 400 Hz adjustable (can be turned off)\u003cbr\u003e\n Bandpass -\u003cbr\u003e\n Subsonic -\u003cbr\u003e\n Phase -\u003cbr\u003e\n Slope high- \/ lowpass Highpass: 12 dB\/Oct.\u003cbr\u003e\n Lowpass: 12 dB\/Oct.\u003cbr\u003e\n Slope subsonic -\u003cbr\u003e\n Slope subsonic \/ lowpass -\u003cbr\u003e\n Signal-to-noise ratio (A-weighted) 99 dB @ full power\u003cbr\u003e\n Distortion (THD @ 1 kHz, 1 W into 4 Ohms) 0.012%\u003cbr\u003e\n Distortion (THD+N @ 1 kHz, 1 W into 4 Ohms) 0.02 %\u003cbr\u003e\n Distortion (THD @ 100 Hz, 1 W into 4 Ohms) -\u003cbr\u003e\n Distortion (THD+N @ 100 Hz, 1 W into 4 Ohms) -\u003cbr\u003e\n Damping factor 70\u003cbr\u003e\n Operating voltage 21 - 32 Volts (max. 5 sec. down to 12 Volts)\u003cbr\u003e\n Idle current 750 mA\u003cbr\u003e\n Fuse 2 x 15 A LP-Mini-fuse (APS)\u003cbr\u003e\n Power rating DC 24 V ⎓ 40 A max.\u003cbr\u003e\n Operating temperature range -40 °C to +70 °C\u003cbr\u003e\n Additional features Active, adjustable crossover, input mode switch, Start-Stop capability, high-level input with automatic turn-on function, ADEP.3, DirectDSP function\u003cbr\u003e \nDimensions (H x W x D) 40 x 248 x 114 mm \/\u003cbr\u003e\n 1.58 x 9.76 x 4.49”\u003cbr\u003e\n * One channel driven (≤ 10% THD+N @ 28.8 V)\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n\u003cbr\u003e\n Scope of delivery\u003cbr\u003e\n 1 x Amplifier HELIX AMPLIFY 204 X-OVER – 24V Edition\u003cbr\u003e\n 2 x Allen keys\u003cbr\u003e\n 3 x Connection cable\u003cbr\u003e\n 2 x Fuses\u003cbr\u003e\n 1 x Mounting material\u003cbr\u003e\n 1 x Instruction manual\u003cbr\u003e\u003cbr\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":56758708076919,"sku":"AMPLIFY 204 X-OVER – 24V Edition","price":259.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/AMPLIFY-204-X-OVER-24V-Perspective-29-09-2026_30484510-208f-4668-99ab-814ae2b3d5ad.jpg?v=1771440202","url":"https:\/\/hifikaupat.fi\/en\/products\/helix-amplify-204-x-over-24v-edition","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
