Accuphase's obsession with audio fidelity shines through in the innovative Balanced AAVA volume control, meticulously preserving the dynamic range of your music at any listening level. Experience unparalleled detail and clarity thanks to the high-efficiency toroidal transformers and separate power supplies for each channel.\u003c\/p\u003e\u003ch3\u003eFull mono construction\u003c\/h3\u003e\u003cp\u003eInside the preamplifier, circuits and components are securely mounted to a sturdy 8 mm thick aluminum frame and kept completely separate for the left and right channels. This reliably prevents unwanted mutual interference, resulting in further improved electrical characteristics and perfectly pure sonic performance.\u003c\/p\u003e\u003ch3\u003eUltra-smooth tactile feel\u003c\/h3\u003e\u003cp\u003eTurning the volume knob on the front panel causes the actual volume level position to be detected. The corresponding combination of weighted amplifiers then in turn adjusts the volume. The volume sensor mechanism is made of a massive aluminum block extruded and finished with utmost precision. The knob provides an exquisite tactile feel when rotated and ensures extremely accurate position detection. The entire mechanism is supported by a floating suspension using insulators, which also allows extremely quiet motor-driven operation when the remote commander is used.\u003c\/p\u003e\u003ch3\u003eIdeal left\/right power supply configuration\u003c\/h3\u003e\u003cp\u003eThe power supply circuitry not only acts as the energy source of an amplifier, it also has a dramatic influence on its sound. The C-2900 features a newly developed type of high-efficiency toroidal transformer in a cast-aluminum case with thermal dissipation fins. Each channel has its own transformer, along with a pair of custom-made electrolytic filtering capacitors rated for high capacity and excellent sonic properties. This arrangement provides ample power reserves for effortless operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e BALANCED\/LINE INPUT, 3 - 200,000Hz +0 -3.0 dB, 20 - 20,000Hz +0 -0.2 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTotal Harmonic Distortion (for all inputs):\u003c\/strong\u003e 0.005%\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e BALANCED 252mV, 0.5V Output 63mV.
