The same warranty conditions apply to refurbished products as to our new products. The product is technically flawless.\u003c\/p\u003e\n\u003cp\u003eThe DP 4.400 is a 4-Channel Amplifier from Hertz with High-Resolution Audio certification. The Class-AB amplification is fully bridgeable and stable at 2 Ω, channels 4 - 3 - 2. The bandwidth at -3 dB ranges from 10 Hz to 45 kHz, the signal-to-noise ratio is 101 dBA, the damping factor is 130 at 1 kHz and 1 W, the distortion is 0.01% at 100 Hz and 70% rated power, and the efficiency is 60%. The supply voltage is 6.5 - 16.5 VDC, the nominal supply is 11 - 15 VDC via 2 x 25 A fuses, the idle current is 0.85 A, and the standby current draw is 10 uA. There are preamplifier and speaker inputs available, a full-range preamplifier output for front, pre-in sensitivity 0.32 - 8 VRMS, and speaker-in sensitivity 1.6 - 40 VRMS. Adjustable crossovers with high-pass and low-pass Full\/50 - 4000 Hz at 12 dB\/octave for front and rear as well as bass boost at 50 Hz from 0 - 9 dB are integrated. ART automatic remote control for turning SPK-IN on\/off (only BTL radio) and minimum load impedances of 4 channels 2 Ω, 3 channels 2 Ω + 2 Ω + 4 Ω, and 2 channels 4 Ω are available.\u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e4-Channel Amplifier\u003c\/li\u003e\n\u003cli\u003eAmplifier Class AB\u003c\/li\u003e\n\u003cli\u003eFully bridgeable\u003c\/li\u003e\n\u003cli\u003eChannels 4 - 3 - 2\u003c\/li\u003e\n\u003cli\u003eStable at 2 Ω\u003c\/li\u003e\n\u003cli\u003eHigh-Resolution Audio certification\u003c\/li\u003e\n\u003cli\u003eInputs for preamplifier and speaker\u003c\/li\u003e\n\u003cli\u003eFull-range preamplifier output for front\u003c\/li\u003e\n\u003cli\u003eAdjustable crossovers\u003c\/li\u003e\n\u003cli\u003eFront high-pass Full or 50 - 4000 Hz, 12 dB\/oct.\u003c\/li\u003e\n\u003cli\u003eFront low-pass Full or 50 - 4000 Hz, 12 dB\/oct.\u003c\/li\u003e\n\u003cli\u003eRear high-pass Full or 50 - 4000 Hz, 12 dB\/oct.\u003c\/li\u003e\n\u003cli\u003eRear low-pass Full or 50 - 4000 Hz, 12 dB\/oct.\u003c\/li\u003e\n\u003cli\u003eBass Boost 50 Hz 0 - 9 dB\u003c\/li\u003e\n\u003cli\u003ePre-in sensitivity 0.32 - 8 VRMS\u003c\/li\u003e\n\u003cli\u003eSpeaker-in sensitivity 1.6 - 40 VRMS\u003c\/li\u003e\n\u003cli\u003eART automatic remote control for turning SPK-IN on\/off only BTL radio\u003c\/li\u003e\n\u003cli\u003eMinimum load impedance 4 channels 2 Ω\u003c\/li\u003e\n\u003cli\u003eMinimum load impedance 3 channels 2 Ω + 2 Ω + 4 Ω\u003c\/li\u003e\n\u003cli\u003eMinimum load impedance 2 channels 4 Ω\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eOperating voltage 6.5 - 16.5 VDC\u003c\/li\u003e\n\u003cli\u003eNominal supply voltage 11 - 15 VDC\u003c\/li\u003e\n\u003cli\u003eFuses 2 x 25 A\u003c\/li\u003e\n\u003cli\u003eIdle current 0.85 A\u003c\/li\u003e\n\u003cli\u003eStandby current draw 10 uA\u003c\/li\u003e\n\u003cli\u003eConsumption at minimum load impedance maximum music power 30 A\u003c\/li\u003e\n\u003cli\u003eRemote control IN 4 - 15 VDC 1.5 mA\u003c\/li\u003e\n\u003cli\u003eEfficiency 60 %\u003c\/li\u003e\n\u003cli\u003eDistortion THD at 100 Hz 70 % rated power 0.01 %\u003c\/li\u003e\n\u003cli\u003eDamping factor at 1 kHz 1 W 130\u003c\/li\u003e\n\u003cli\u003eBandwidth at -3 dB 10 Hz - 45 kHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio A-weighted at 1 V input 101 dBA\u003c\/li\u003e\n\u003cli\u003eOutput power RMS at 1 % THD 4 channels at 4 Ω 75 W x 4\u003c\/li\u003e\n\u003cli\u003eOutput power RMS at 1 % THD 4 channels at 2 Ω 105 W x 4\u003c\/li\u003e\n\u003cli\u003eOutput power RMS at 1 % THD 3 channels at 4 Ω 75 W x 2 + 210 W x 1\u003c\/li\u003e\n\u003cli\u003eOutput power RMS at 1 % THD 3 channels at 2 Ω\/4 Ω 105 W x 2 + 210 W x 1\u003c\/li\u003e\n\u003cli\u003eOutput power RMS at 1 % THD 2 channels at 4 Ω 210 W x 2\u003c\/li\u003e\n\u003cli\u003eOutput power at 14.4 VDC 10 % THD 4 channels at 4 Ω 90 W x 4\u003c\/li\u003e\n\u003cli\u003eOutput power at 14.4 VDC 10 % THD 4 channels at 2 Ω 125 W x 4\u003c\/li\u003e\n\u003cli\u003eOutput power at 14.4 VDC 10 % THD 3 channels at 4 Ω 90 W x 2 + 250 W x 1\u003c\/li\u003e\n\u003cli\u003eOutput power at 14.4 VDC 10 % THD 3 channels at 2 Ω\/4 Ω 125 W x 2 + 250 W x 1\u003c\/li\u003e\n\u003cli\u003eOutput power at 14.4 VDC 10 % THD 2 channels at 4 Ω 250 W x 2\u003c\/li\u003e\n\u003cli\u003eTotal power 1000 W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":53173232435467,"sku":"DP-4.400-B","price":229.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9478\/5927\/files\/hertz-dp-4_400-4-kanal-verstarker-masori-kaufen.jpg?v=1747975104","url":"https:\/\/masori.de\/en\/products\/dp-4-400-b-ware","provider":"Masori | Shop","version":"1.0","type":"link"}
