From the electron, Mcintosh (Macintosh) solid state output & vacuum tube output preamplifier "C12000" has been released.The price is $ 2,530,000 (tax included).
The C12000 is a next -generation preamplifier with a 2 -chassis configuration that inherits the concept of the "C1100".By completely separating the audio and control/power supply for music signals, high -pure music playback is enabled.The main features are as follows.
● Adopts a two -chassis configuration of C12000C (controller) and C12000ST (preamplifier).Divide power supply circuits, microcessors, and control circuits from audio circuits that handle music signals, and completely eliminate noise that adversely affect music signals.In addition, the circuit of both channels is physically separated and shielded.In addition, the power supply part is independent, achieving a complete separation between the channels and realizing a true dual monaural operation.
● The latest complete balance circuit is adopted from the input terminal to the output terminal to minimize noise and distortion.
● The analog input is equipped with a total of 12 systems: 6 balance, 4 unbalanced, and two phonos.The two phono input of the two systems can be set in either "Moving Magnet" or "Moving Coil", and the load impedance and capacity and gain can be adjusted.The load impedance can be selected from 25Ω to 47,000Ω, and the capacity of the electrostatic capacity can be selected from the 50 picofalad to 400 picofalad.
● Equipped with both vacuum tube and solid state output.The preamplifier part with a vacuum tube output is located with 12AT7 x 2 and 1 12AX7A x 1 vacuum tube per channel.The solid state output uses a balanced operational amplifier.
-The pre -out output terminal is a total of four systems: vacuum tube (balance), solid state (balance), fixed imbalance, and programmable unbalance (vacuum tube, semiconductor selection type).
● A vacuum tube amplification circuit using 12AX7A is used for phono input.With a full balance configuration used for each channel, the RIAA correction equalizer circuit uses narrow tolerance resistance and condenser to achieve a flat frequency characteristics.
● Volum is controlled by a high -precision balance digital control attenuator equipped with an optical rotary encoder.As a result, a 0.1 dB tracking accuracy is secured between channels.The volume level is set to 214 steps in 0.5db increments, and no noise occurs even if the level changes.
● Power control ports can easily launch and shut down the system by sending power on/off signals to other connected macintosh equipment.The data port can send a remote control command to the connected source device.
● Equipped with a high -drive headphone amplifier with sufficient power and flexibility to drive a wide headphones.The standard plug headphone output uses HXD.
● Macintosh is a simple and fearless glass front panel.Stainless steel steel chassis can maintain the same shine as a new one with simple care.
