General Information, Cable Information, Introduction and Performance Features
Introduction
Now you can take advantage of traditional McIntosh
standards of excellence in the MC2152 Tube Power
Amplifier. The 150 watt power output per channel
will drive any high quality Loudspeaker System. The
MC2152 reproduction is sonically transparent and ab-
solutely accurate. The McIntosh Sound is “The Sound
of the Music Itself.”
Performance Features
• Power Output
The MC2152 is a Tube Power Amplifier with a ca-
pability of 150 watts per channel into 2, 4 or 8 ohm
Loudspeakers with less than 0.5% distortion.
• Unity Coupled Circuitry
The MC2152 Power Amplifier uses the famous McIn-
tosh Patented Unity Coupled Circuit which provides
low distortion, extended frequency response and cool
operating output tubes.
• Multifilar Wound Output Transformer
The MC2152 Output Transformer Windings are part
of the Unity Coupled Circuitry. There are two bifilar
wound primaries, one for the cathodes and one for
the plates. The secondary winding is wound together
with the primary windings. This provides very close
primary to secondary coupling. The result is flat fre-
quency response and wide power bandwidth.
• Balanced and Unbalanced Input
Balanced connections guard against induced noise and
allow long cable runs without compromising sound
quality.
• Sentry Monitor Tube Protection
McIntosh Sentry Monitor Tube Protection Circuits
ensure the MC2152 will have a long and trouble free
operating life.
• Vacuum Tube Sockets
Small Signal Vacuum Tubes Sockets have Ceramic
Base construction with gold plated contacts, providing
protection from atmospheric contamination. Output
Tube Sockets include Air-Pipe cooling at their bases
for long term operation.
• Amplifier Gold Plated Connectors
Gold Plated Input Jacks and Output Binding Posts
provide trouble free connections.
• Special Power Supply
A regulated Power Supply, a very large core Power
Transformer and large capacitors ensure stable noise
free operation even though the power line varies.
• LED Tube Illumination
Tri-Color LEDs illuminate the small signal process-
ing tubes of the MC2152. They indicate tube warm up,
normal and sentry monitor modes of operation.
• Special Chassis
The Aluminum Extrusion Heavy Duty Chassis is a
Highly Rugged Construction for the very large size
of the MC2152 McIntosh Tube Power Amplifier. This
type of design will retain the pristine beauty of the
MC2152 for many years to come.
