MCINTOSH MA6500 INTEGRATED AMPLIFIER

MA6500, to a higher dimension. Polished Macintosh quality. If multiple manufacturers make amplifiers with exactly the same circuit, the sound quality of the resulting amplifiers will be very different, which is a clear fact in the world of audio that has been digitized so much. You can say that. The Macintosh's excellence is sound quality in the first place. A rich and delicate Macintosh sound that has been refined for many years and has continued to fascinate lovers around the world. In addition, its appearance is an important element that expresses the idea of ​​the manufacturer. If you can't express it, so is the sound. The most advanced technology and know-how. For example, a phono equalizer with an extraordinary power equivalent to 100mW. Alternatively, a tone control that is completely disconnected from the signal path at the center click position. A line amplifier that clears a large input of 10V. And a power amplifier that keeps extremely low distortion of 0.005% or less from 250mW to the maximum rated output. The logic control by the sealed reed relay which is virtually distortion-free and does not deteriorate with time is adopted as a selector. These specifications and circuit design devices are exactly the same as Macintosh separate amplifiers. Moreover, the peak power reaches about twice the rated output of 120W + 120W, and the distortion does not exceed 0.005% even when the instantaneous peak power is 400W output per channel.

● Traditional full-glass front panel boasting multiple functions
Macintosh traditional jet-black glass front panel. The names of the various control switches illuminated in the green and the Blue Eyes power meter create that crush in the concert hall before the music begins.
● Blue Eyes Large peak output meter The
meter uses a high-speed, high-precision type that operates 10 times faster than a commercial VU meter. It responds from 95% of full scale to a 2kHz sine wave tone burst.
● High-precision volume control
Equipped with a motor drive high-precision volume control that enhances operability. The left and right sections are electronically trimmed for excellent tracking.
● Macintosh's original tone control The
tone control boosts or cuts the low and high frequencies by 12 dB. When the knob is in the center position, the tone control circuit completely passes the signal path. The circuit achieves extremely high transient performance and extreme distortion.
● Highly stabilized power supply The
regulator maintains stable operation even when the voltage of the AC power supply, which is the so-called "brownout", drops.
