McIntosh C220 525,000yen(including-tax. around the 2007 time)

The tube preamplifier which supplied the newest digiteches, such as adoption of a digital control volume, to the tradition of amplifier structure of a mac.

Thermionic-tube 12AX7A is performing all amplifications of the signal. Moreover, the mute of the output is carried out until it will be in the status that the thermionic tube can get warm and output by an automatic turn-on delay, and the influence of the noise by an external equipment etc. is reduced.

The VRV (Variable Rate Volume) digital electronic volume of 214 steps is adopted per 0.5dB.
While enabling volume control with an analog volume sensation by this, it is strong to secular change of a contact, and the stable operation has been obtained.

The input selector in which a special NetWare program is possible is carried.

The illumination structure by the optical diffusion fiber which improved the visibility without spoiling an appearance design is adopted as a fluorescent-light display device.

Wireless remote control is attached.
