The signal path is balanced from input to output, with a high-gain MC\/MM head amplifier followed by a precision equalizer amplifier, and each channel is built as a separate monaural circuit on a symmetrical glass-cloth fluorocarbon board. Four 15,000 µF capacitors per channel and a dedicated low-noise supply for the ANCC circuit feed it.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px\"\u003eOne balanced MC input and three standard phono inputs let you run several arms or turntables. MC loading is selectable at 10, 30, 60, 100, 200 and 300 ohms and 1 kΩ, MM at 1 k, 47 k and 100 kΩ, gain is switchable between normal and high, and there is a 10 Hz subsonic filter and a polarity selector on the balanced output. With RIAA accuracy of ±0.3 dB and 98 dB signal-to-noise at 64 dB of MC gain, it is one of the quietest phono stages we have heard, and the right partner for a C-2300 or C-3900S.\u003c\/p\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eKey technologies\u003c\/h3\u003e\n\u003cul style=\"margin:0 0 20px;padding-left:18px\"\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eANCC in the head amplifier.\u003c\/strong\u003e Accuphase's Noise and distortion Cancelling Circuit is applied to the MC\/MM head amplifier for the first time, with its own low-noise power supply.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eFully balanced signal path.\u003c\/strong\u003e Balanced amplification in both the head amplifier and the equalizer amplifier, from the balanced MC input to the balanced output.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eMonaural construction.\u003c\/strong\u003e Left and right channels are separate circuits laid out symmetrically on a glass-cloth fluorocarbon resin board, each with four 15,000 µF supply capacitors.\u003c\/li\u003e\n\u003cli style=\"margin:0 0 5px\"\u003e\n\u003cstrong\u003eFlexible loading and gain.\u003c\/strong\u003e Seven MC load settings including a new 60 Ω position, three MM settings, two gain ranges, a 10 Hz subsonic filter and output polarity selection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"margin:0 0 8px;font-size:16px\"\u003eFinishes\u003c\/h3\u003e\n\u003cul style=\"list-style:none;margin:0 0 6px;padding:0\"\u003e\n\u003cli style=\"display:flex;align-items:center;gap:10px;margin:0 0 6px\"\u003e\n\u003cspan style=\"flex:0 0 18px;width:18px;height:18px;border-radius:50%;background:#d9c69b;border:1px solid #d8d5ce\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eChampagne gold\u003c\/strong\u003e \u003cspan style=\"color:#55524c\"\u003eanodized aluminum front panel\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"display:flex;align-items:center;gap:10px;margin:0 0 6px\"\u003e\n\u003cspan style=\"flex:0 0 18px;width:18px;height:18px;border-radius:50%;background:#8a5a35;border:1px solid #d8d5ce\"\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eNatural wood\u003c\/strong\u003e \u003cspan style=\"color:#55524c\"\u003eside panels with a natural wood-grain finish\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin:0 0 20px;font-size:13.5px;color:#55524c\"\u003eAccuphase builds every component in a single finish, so there is nothing to choose.
