Accuphase C 2850 is a next-generation preamplifier of Top-of-the-line quality, which uses a patented analog balanced volume control – AAVA.
The AAVA processor changes the signal level in steps depending on the position of the volume control. The latest AAVA volume control ensures incredibly smooth sound and a completely comfortable listening experience at different volume levels.
The Accuphase C 2850 power supply contains two powerful toroidal shielded transformers filtered by 4 capacitors of 10,000 uF each. The resulting current gives the circuit a variable gain, which controls the volume of the music signal. The corresponding current is combined and converted into voltage at the inverter (IV) before being sent to the next stage.
Amplifiers directly change the gain and allow you to change the volume without changing the characteristic impedance, as well as noise and various distortions.
The Accuphase C 2850 volume control knob is machined from a high quality solid piece of aluminum. The body is made of 8 mm high quality anodized aluminum. The top cover is made of solid Japanese persimmon, covered with 12 layers of varnish and polished.
The entire audio signal path from the preamplifier input to the amplifier output is completely balanced. The Accuphase C 2850 preamplifier uses eight signal amplification units per channel. The printed circuit boards of the amplification units are made of fluorocarbon fiberglass fabric impregnated with fluorocarbon resin. This housing design reliably protects circuits from various types of interference and interference, and also has excellent anti-vibration properties. All boards are made of fluorocarbon resin, which has a very low dielectric constant and minimal losses.
Accuphase C 2850 is equipped with signal phase indication. You can select the phase individually for each input. If the indicator is on, phase 180, and if the indicator is off, phase 0.
The built-in high-quality headphone amplifier has three gain positions Low, Mid and High.
Optionally, you can install the AD-2850 MM/MS phono stage board. The Accuphase C 2850 preamplifier is mounted on anti-vibration feet, which are made of high carbon cast iron. The outstanding performance and design of this preamplifier delivers realism that will simply take your breath away and blow you away with sound.
