バスシステム対応 MDレシーバー — The Sony MDX-C500X is a MiniDisc receiver built around Sony's Mobile ES "Bus" system — a single cable links it to other Sony bus components (separate displays, CD changers, EQ units) while this unit itself handles MD playback, FM/AM tuning, and a 50W×4 amplifier from one compact chassis. Tone controls give ±9dB of bass and treble adjustment, and the bus inputs/outputs mean it slots neatly into an existing Sony multi-unit setup. A clean, no-nonsense MD deck from Sony's bus-era lineup. Product was in working condition upon our initial assessment, upon second assessment the product was having troubles powering up. If you're handy, you'd probably be able to make it work, hence the heavy discount. We don't have the time for it at the moment, so If you want to save a buck this is for you.
