McIntosh MA6600 - LITERATURE

MA6600
integrated amplifier
legendary
The MA6600 integrated amplifier teams a very low distortion, full function preamplifier
with a potent 200 Watt per channel autoformer-coupled amplifier. The ability to accept
an optional AM/FM/HD tuner module, the TM2, enables the MA6600 to become the first
stereo receiver offered by McIntosh in over 15 years.
The preamplifier stage supports 1 balanced and 7 unbalanced inputs and the input
names are user configurable. A Variable Rate Volume (VRV) control with Post Attenuator,
a McIntosh innovation, provides exceptionally accurate tracking and very low noise
operation. Bass, treble and balance functions are all digitally controlled and adjustable
via the MA6600 front panel or IR remote and bass and treble settings are automatically
memorized independently for each input selection. All signal routing is accomplished
with highly reliable, sealed electromagnetic switches. A ¼” front panel jack accesses
a dedicated, low impedance headphone amplifier for use with dynamic headphones.
Two switched, unbalanced line outputs are available for multi-zone use.
The MA6600 power amplifier utilizes a 2-stage differential-balanced voltage amplifier
coupled to a push-pull current amplifier and Output Autoformer. This topology exhibits
extremely low noise and distortion along with high current capability and is designed
to drive a wide range of loudspeakers to sound their very best. The output Autoformer
enables the MA6600 to respond with full rated power and low distortion regardless of
the load connected and delivers 200 watts per channel into 8, 4 or 2 ohms.
