Performance Features
••
••
• Triple Chassis Mono Block Design
For the first time, the new McIntosh MC2KW Power Am-
plifier is capable of supplying the power required to repro-
duce the full dynamic range of a symphony orchestra in-
cluding pipe organ. This includes driving low efficiency
Loudspeakers in a large room to concert hall volume levels.
It can reproduce complex music with complete accuracy,
with no added distortion or noise. The Triple Chassis De-
sign also allows for easier placement in a room than would
be possible in a single chassis design, yet with no compro-
mise in performance or reliability.
• Power Output
The MC2KW Power Amplifier is capable of 2,000 watts
into 2, 4 or 8 ohm speakers with less than 0.005% distor-
tion. It can provide peak current of 200 amperes and over
8,000 watts of power output on music bursts.
••
••
• Full Balanced Quad-Differential Circuitry
The MC2KW Power Amplifier is fully balanced from in-
puts to outputs. It consists of two matched MC2KW Power
Modules, each operating in push-pull with their outputs
combined in a McIntosh Autoformer located in the
MC2KW Output Module. This double balanced configura-
tion cancels virtually all distortion.
••
••
• Patented Power Guard
The patented McIntosh Power Guard circuit prevents the
amplifier from being overdriven into clipping, with its harsh
distorted sound that can also damage Loudspeakers.
••
••
• Patented Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protection cir-
cuits ensuring each MC2KW Power Module will have a
long and trouble free operating life. Built-in Thermal Pro-
tection Circuits guard against overheating.
••
••
• Patented Autoformer
McIntosh designed and manufactured Output Autoformers
provide an ideal match between the amplifier output stages
and speaker loads of 2, 4 and 8 ohms. The Autoformers also
provide perfect DC protection for your valuable Loudspeak-
ers.
••
••
• Illuminated Power Meter
The Illuminated Power Output Watt Meter is peak respond-
ing, and indicates the true power output of the amplifier.
The Peak Watt Hold Mode allows the meter to temporarily
stay at the highest power output and then slowly decay.
••
••
• Power Control
The McIntosh Power Control Circuit allows for remote
turn-on of the MC2KW Power Amplifier from a McIntosh
Audio/Video Control Center or Preamplifier. If any addi-
tional McIntosh Power Amplifiers are part of the system,
there is a delayed Power Control Output. This delayed trig-
ger reduces the strain on the house’s electrical wiring and
protection devices.
••
••
• Balanced Inputs and Gold Plated Outputs
Balanced connections guard against induced noise and al-
low long cable runs without compromising sound quality.
There are three sets of gold plated five way binding posts
for each of the three output impedances.
••
••
• Precision Parts
All resistors are precision metal film type. Low dielectric
absorption film capacitors are used in all critical circuit lo-
cations.
••
••
• Fiber Optic Solid State Front Panel Illumination
The Illumination of the 1/2 inch thick laser etched Front
Panel Glass is accomplished by the combination of custom
designed Fiber Optic Light Diffusers and Light Emitting
Diodes (LEDs). This provides even Front Panel Illumina-
tion, together with the extra long life LEDs.
••
••
• Glass Front Panel and Super Mirror Chassis Finish
The famous McIntosh Illuminated Glass Front Panel with a
Stainless Steel Chassis with Super Mirror Finish ensures
the pristine beauty of the MC2KW will be retained for
many years.
••
••
• Machined Top and Side Panels
The Top and Sides of the MC2KW Output and Power Mod-
ules are machined from thick aluminum panels with a
smooth black anodized finish. There is a screened glass
panel in the recessed areas of the Top Panel, with a block
diagram of the Circuitry.
••
••
• Special Power Supplies
The MC2KW Output Module utilizes a special R-Core
Power Transformer together with an electronically fully
regulated Power Supply Circuitry. The MC2KW Power
Modules each utilize a large Toroidal Wound Power Trans-
former with large filter capacitors capable of storing 430
Joules of energy.
