One module converts a consumer device's stereo output up to balanced levels and feeds its stereo input from a balanced source. Front-panel RCA and XLR jacks plus rear terminal blocks make it a practical rack interface for media players, PCs and recorders.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ru-afc2.jpg\" alt=\"RDL RU-AFC2 Stereo Bi-Directional Audio Format Converter\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe unbalanced-to-balanced section accepts left and right RCA inputs and delivers +4 dBu balanced outputs on front-panel XLR jacks and rear detachable terminal blocks. It also provides a mono summed output on a rear terminal block, wired balanced or unbalanced, for patch bays, powered monitors or subwoofer amplifiers. The balanced-to-unbalanced section accepts XLR or terminal block inputs and delivers -10 dBV outputs on front-panel RCA jacks. A rear-panel ground-lift switch connects the XLR output shields to the case, which helps resolve ground loops. Each output channel has a front-panel multi-turn level trimmer and a dual-LED VU meter whose red LED flashes at the calibrated level. Frequency response extends from 10 Hz to 150 kHz (±0.25 dB) with more than 20 dB of headroom in both sections. The module operates from ground-referenced 24 Vdc at 60 mA idle and 100 mA maximum; RDL recommends the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX\u003c\/a\u003e (international) power supply, not included.
