Features and Benefits
NEW DOUBLE BALANCED PUSH PULL DESIGN
The MC1000 amplifier is fully balanced from
input to speaker output. Two matched amplifiers
operate in PUSH-PULL with their outputs combined in
the "Output Autoformer". Each half of the amplifier
contains complimentary balanced circuitry. The resulting
double balanced configuration cancels virtually all
distortion. This circuit is possible ONLY with the
exclusive "MclNTOSH OUTPUT AUTOFORMER".
HIGH OUTPUT CURRENT
Greater than 160 amperes peak output current
to drive uneven speaker loads. Some poor speaker
designs have input impedances that dip to 1 or 2 ohms
at various frequencies. The MC1000 has the output
current reserve to drive them. Over 4KW output on tone
bursts.
OVER 400 JOULES OF ENERGY STORAGE
Huge main filter capacitors that guarantee an
excellent signal to noise ratio and the energy storage
necessary for the wide dynamic range that "Digital
Audio" demands.
GOLD PLATED OUTPUT TERMINALS
Mclntosh gold output terminals deliver full power
output to speaker wires from 18GA to 4GA (4GA is
.204 inches in dia. You can connect directly to the
wire. Special lugs or pins that can cause power loss
are not required. Single or Dual "BANANA" plugs may
also be used.
ILLUMINATED PEAK RESPONDING OUTPUT WATT-
METER
The Mclntosh MC1000 is the first high power
amplifier to have an Output Wattmeter that responds
