McIntosh Laboratory Introduces The

MA2275 Vacuum Tube Integrated Amplifier

Binghamton, NY December 15, 2003—McIntosh Laboratory, a world leader in home entertainment systems for

over 53 years, introduces the MA2275 Tube Integrated Amplifier.

Producing a minimum of 75 watts per channel in stereo with 2, 4, or 8-ohm speakers, the MA2275 combines classic

McIntosh vacuum tube audio performance with state-of-the-art control circuitry. Flexibility is never compromised in

a McIntosh. The MA2275 features include a built-in low noise moving magnet phono input, one set of XLR jacks

for a balanced input, 6-sets of unbalanced inputs, preamp out/amplifier in loop, and an extra set of pre-outs.

The exclusive McIntosh Unity Coupled output circuit evenly distributes the load to the output tubes and provides

clean power over the entire frequency range in the MA2275 power stage. This unique feature enables the MA2275

to operate at maximum efficiency with extremely low noise and distortion while delivering full power without

stress. McIntosh Silent Electromagnetic Input Switching utilizes ruthenium contacts sealed in glass cylinders filled

with an inert gas to prevent signal degradation. Because the switching nodes are located on circuit boards at the

inputs themselves, McIntosh Silent Electromagnetic Switching eliminates internal wiring in the signal path and

literally brings the switch to the input.

The MA2275 will ship early 2004 will be officially introduced at CES 2004 where it can be seen along with

McIntosh's other outstanding products at the McIntosh booth located at Alexis Park in the Executive Board Rooms.
