It lets installers preamplify a phonograph close to the turntable in commercial audio systems.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/st-ph1.jpg\" alt=\"RDL ST-PH1 Stereo Phono Preamplifier with RIAA EQ\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe ST-PH1 has two identical channels with standard 47 kΩ unbalanced phono cartridge inputs. Equalization follows the RIAA curve, and left and right output levels are adjustable. Each output can drive balanced or unbalanced, high or low impedance loads. RDL SupplyFlex power accepts a floating 24 Vdc source, a bipolar ±12 or ±15 Vdc supply, or a ground-referenced 24 Vdc supply such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX\u003c\/a\u003e.
