Yamaha C-60 is a natural sound stereo control amplifier that provides extensive choice in frequency response with Bass and Treble controls. The Turnover Frequency selectors can widen or narrow the range affected by the Level selectors to adjust for room acoustics, speaker placement, or personal preference. It has a subsonic filter that cuts out ultra-low-frequency signals caused by warped records or turntable rumble. It also features a mode switch between stereo and mono modes. Additionally, it offers connections for two turntables, a tuner, two tape decks, and other sources.
