■ The MHA200 Vacuum Tube Headphone Amplifier is for discerning
headphone enthusiasts who demand the most from their headphones.
■ Offers a versatile set of connectivity options, including balanced
inputs and outputs, allowing nearly all headphone types to enjoy an
extraordinary personal listening experience.
■ Three options for attaching your headphones: a pair of 3-pin balanced
XLR connectors for dedicated Left and Right balanced output; a 4-pin
balanced XLR connector for balanced stereo output; and a 1/4” stereo
headphone jack.
■ Uses a pair of our Unity Coupled Circuit output transformers to deliver
pristine audio to your ears.
■ The Unity Coupled Circuit transformers have been adapted to produce
4 headphone impedance ranges of 32 – 100, 100 – 250, 250 – 600, and
600 – 1,000 Ohms at 500mW so that virtually every headphone can
receive legendary McIntosh sound quality and performance.
■ Powered by a pair of 12AT7 and 12BH7A dual triode vacuum tubes.
■ Thanks to the MHA200’s small size of just 6-1/8” (15.6cm) wide x
9-1/8” (23.2cm) deep and its balanced inputs, it can be placed close to
your listening position for ease use, with long balanced audio cables
connecting it to your audio system without fear of signal loss.
■ Includes volume control so it can be connected directly to music sources
that have fixed volume output
