“ high bandwidth in a

tube amplifier thanks to an

innovative McIntosh circuit”

Almost fifty years ago Frank McIntosh and Gordon Gow invented
and patented the McIntosh Unity Coupled Output Circuit. Two features
differentiate from other designs. First, the output tubes deliver power
from both their plates (anodes) and their cathodes, not from their plates
alone as in conventional circuits. Second, the output transformer’s two
bifilar primary windings give it one-half the turns ratio of conventional
transformers, equating to one-fourth the impedance ratio. This allows a
close coupling of the primary and secondary windings, resulting in wide
bandwidth, flat frequency response, and low distortion. The MC2102 is
at once a tribute to the past and present McIntosh.

This characteristic is ideal for both analog and the latest ultra
high-resolution digital formats.

The MC2102 will deliver 100 watts per channel into a full 20-20,000Hz
band, and deliver that power with 8, 4, or 2 ohm speakers.

Balanced and unbalanced inputs and huge gold-plated speaker
terminals provide the connectivity you need.

UNITY COUPLING

The McIntosh Unity

Coupled Output Circuit with

four output tubes (KT88) per

channel in a push-pull parallel

configuration for high power

of 100 watts per channel.

ACCURATE METERS

The illuminated peak-responding

meters display output power
in watts. Response is almost

10 times faster than a VU meter.

HIGH CONNECTIVITY

Balanced input connectors guard

against noise pick up and allow

long input cable runs without

compromising sound quality.

Huge Gold-Plated Output Posts

with connections for 2, 4, and

8 ohms. This ensures you get

all the power you paid for with

any type of loudspeakers.

Mono-Bridge and Mono-Parallel

modes enable the MC2102

to deliver a full 200 watts

as a mono amplifier into

1, 2, 4, 8 or 16 ohm loads.

FREEDOM FROM DISTORTION

Low Distortion is a hallmark

of McIntosh tube amplifiers.

Distortion remains under

0.5% THD and IM over the

complete range of 20-20kHz.
