Nakamichi 610

Description

The Nakamichi 610 was created to fill an often expressed gap in the consumer audio market. It is a remarkably flexible control center that must be considered truly unique by any standard.

It's uniqueness stems not only from its amazing features, but from its even more amazing performance as well. It does, after all, carry the Nakamichi brand name. To some audiophiles, no more need be said. But there is more - much more.

First and foremost, the Nakamichi 610 is a state-of-the-art preamplifier. This much overused phrase can certainly be applied to a preamplifier with noise level so close to the theoretical limit and distortion so low that these parameters can barely be measured with today's best available test equipment. Specifications only begin to tell the story.

Secondly, the Nakamichi 610 is a relatively sophisticated test instrument. Built-in test tone oscillators, pink noise generator, phase checkers and precision dB meters, just to name a few, make the 610 an invaluable tool in the calibration, alignment and evaluation of stereo system components.

Special switching features facilitate the A/B comparison of phono cartridges, tape decks, power amplifiers, loudspeakers, etc.

Last, but not least, the Nakamichi 610 is a mixing console. It allows 5 in/2 out mixing of any of 19 different inputs. This includes 5 wide-dynamic-range microphone inputs. One can, for example, mix two tape decks (stereo, of course) plus center channel voice onto a third tape deck, or two phonographs plus voice, or any combination of these sources. Live recording takes on a new dimension with the 610: with two left, two right and one blend microphone inputs the live recordist can produce some very professional results.

The Nakamichi 610, in short, will become a must for the serious audiophile. Even the audiophile who has everything will wonder how he ever managed to do without the 610.
