It provides separate current-drive and voltage-drive outputs rather than treating both headphone sockets as interchangeable.\u003c\/p\u003e\n\u003cp\u003eIts discrete Ensence input stage feeds two different output circuits: a MOSFET voltage stage derived from the AMP-23R and a bipolar-transistor current stage descended from the HPA-21. Battery power and USB-C charging make it usable away from a fixed desktop system.\u003c\/p\u003e\n\u003ch3\u003eBefore you connect\u003c\/h3\u003e\n\u003cp\u003eConnect an analogue line-level source to the RCA or 3.5 mm input; this is a headphone amplifier, not a USB DAC. The 6.35 mm socket is the current output and the 3.5 mm socket is the voltage output. Start with the volume low and select the output appropriate to your headphones. USB-C is used for charging or external power.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003ctable\u003e\n\u003ccaption\u003eModel specifications\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eInputs\u003c\/th\u003e\n\u003ctd\u003eRCA and 3.5 mm analogue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCurrent-drive output\u003c\/th\u003e\n\u003ctd\u003e6.35 mm headphone jack; bipolar-transistor circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVoltage-drive output\u003c\/th\u003e\n\u003ctd\u003e3.5 mm headphone jack; MOSFET circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePower supply\u003c\/th\u003e\n\u003ctd\u003eRechargeable battery; USB-C charger or battery pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e116 × 164.5 × 22 mm (W × D × H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eNet weight\u003c\/th\u003e\n\u003ctd\u003e750 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Enleum","offers":[{"title":"Default Title","offer_id":67813790253270,"sku":"HFL-U-9B11D29B91","price":2239.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/7445\/9862\/files\/57_b7d74b8d-27db-4135-b67f-444c58ab68b9.png?v=1793190913","url":"https:\/\/hifiloop.com\/zh\/products\/enleum-hpa-23rm-pre-owned-9b11d29b91","provider":"HiFiLoop","version":"1.0","type":"link"}
