Specifications

95% full scale to a single cycle tone burst at 2kHz.
Voltage and current output are electronically measured,
multiplied and fed to a special circuit that accelerates
the pointer movement in the upward direction. When
the pointer reaches its peak it pauses only long enough
for the human eye to perceive its position, then drops.
It is almost 10 times faster than a professional VU
meter.
WATTS HOLD
The "Watts Hold" mode for the output meter,
records and displays the highest power output peak of
the source material being amplified.
ULTRA LOW DISTORTION
Distortion so low that it defies measurement, even
with the finest distortion analyzers. At mid-frequencies,
8 ohm load, the distortion meter reads the residual
distortion of the oscillator (.0002%) with or without the
MC1000 in the circuit. This means the amplifier
distortion is lower than the analyzer is capable of
measuring.
WIDE POWER BANDWIDTH
Full power output capability well above and below
the frequencies that can be heard by humans.
POWER GUARD
The exclusive Mclntosh circuit that prevents harsh
sounding clipping and helps protect your speakers from
damage.
THERMAL PROTECTION
Thermal sensors that turn off the AC power if
improper loading or ventilation causes the amplifier to
over heat.
TURN ON DELAY
The MC1000 has a circuit that delays amplifier
operation for about two seconds after turn on. This
prevents pops or thumps generated in other equipment
from causing annoying noises or damaging your
speakers.
BALANCED INPUT
Modern technology has made it possible to build
preamps and amps with the high signal to noise ratio
necessary to reproduce the sound quality present on
compact discs. However, the interconnecting cables
can pick up interference from other equipment or
appliances. The balanced input on the MC1000
provides a minimum of 40dB (100 times) more
protection against such noise pick up.
OUTPUT AUTOFORMERS
The unequaled expertise of Mclntosh in the
design and manufacture of output transformers is leg-
endary in the Hi Fi industry. In the MC1000 it provides
proper matching for 2, 4 and 8 ohm loads. It protects
your speaker from damage in the event of an output
transistor failure, provides low distortion power transfer
at frequencies well beyond human hearing and delivers
peak output current in excess of 160 amperes.
REGULATED ILLUMINATION
The tremendous peak output power capability
of the MC1000 has made the addition of a circuit that
regulates the brilliance of the panel and meter
illumination necessary. When there are high power
output demands the line voltage may sag however this
new circuit prevents the lights from dimming.
MODULAR CONSTRUCTION
If service should be required, modular
construction makes repairs easier. Gold plated
connectors are used to assure long life and distortion
free connections even in hostile environments.
SILENT CONVECTION COOLING
New "High Efficiency Circuits", superior
components and large area heatsinks, over 2,800 square
inches, contribute to cool operation. No fans are
required.
