Features and Benefits

BALANCED DESIGN

The MC2301 amplifier is fully balanced

from input to speaker output. Two matched

amplifiers operate in Push-Pull with their

outputs combined in the Output Transformer.

The balanced configuration cancels many

distortion products. The Signal-to-Noise ratio

is also superior.

MCINTOSH UNITY COUPLED OUTPUT

CIRCUIT

Output power is taken from both the plate

and cathode of the output tubes. Conventional

designs only take output from the plate. This

allows ½ the turns ratio, or ¼ the impedance

transformation of conventional designs. The

result is much lower distortion, wider

bandwidth and increased loudspeaker

damping factor.

MULTIFILAR WOUND OUTPUT

TRANSFORMER

The Unity Coupled Output Transformer

has two bifilar wound primaries, one for the

cathodes and one for the plates. The

secondary is wound together with the primary

windings. This provides very close primary to

secondary coupling. The result is flat

frequency response and wide power

bandwidth.

LOW DISTORTION FROM 20Hz TO 20kHz

Less than 0.5% THD over the entire audio

band is uncommon for a tube amplifier.

WIDE POWER BANDWIDTH

Full power output is available well beyond

the frequencies that can be heard by humans.

The specified frequency range is 20 to

20,000Hz.

SENTRY MONITOR TUBE PROTECTION

Sentry Monitor protects the entire amplifier

circuitry in the event that a mismatched load

impedance or a failed Output Tube causes

higher than normal current to flow. To prevent

destruction, the MC2301 power is turned off.
