The frequency range extends up to 50 kHz, with a -3 dB bandwidth of 10–45 kHz – ideal for detailed high-frequency reproduction. Thanks to 2 Ω stability, bridgeable channels, and front pre-out, you can set up various system configurations, from an active front system to a bridged sub\/front setup. Balanced inputs, Auto Turn-On (ART), and speaker inputs facilitate integration into OEM radios. A status LED and removable top plate complete the design.

Thanks to speaker inputs and ART function, retrofitting to OEM BTL radios is easy. The 2 Ω stability in 4-channel operation and the filters with 50–4000 Hz allow for clean crossovers – active or passive, depending on the concept. The power supply operates safely within the range of 6.5–16.5 V.\u003c\/p\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":52841086320976,"sku":"DP 4.300","price":189.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/3004\/7312\/files\/hertz-dp-4_300-4-kanal-verstarker-carhifi_shop-kaufen.jpg?v=1774448510","url":"https:\/\/carhifi.shop\/en\/products\/hertz-dp-4-300-4-kanal-verstaerker","provider":"Carhifi Shop","version":"1.0","type":"link"}
