PERFORMANCE,
UNLIMITED PERFORMANCE IS A DESIGN REQUIREMENT AT MclNTOSH
Low distortion is a
requirement For high performance in a preamplifier. A typical wave form
analysis of the C 26 at 2,5 volts output is a 99.95% perfect reproduction of
the input wave, 20 Hz through 20,000 Hz!
Performance is
important to your listening expectations. With a Mclntosh you are assured of
highest performance because Mclntosh guarantees performance. Your C 26 must be
capable of meeting its advertised specifications or your purchase price will be
refunded. Mclntosh promises performance and delivers performance.
RELIABILITY IS A
DESIGN REQUIREMENT AT MclNTOSH
Endless hours are
invested by our engineers carefully and thoroughly testing and retesting
individual component parts. These hours are required to provide you with the
highest degree of reliability that modern design and manufacturing can produce.
Only because of this exhaustive program can Mclntosh guarantee you complete
freedom from service costs tor the first THREE YEARS that you own your C 26,
LONG LIFE IS A
DESIGN REQUIREMENT AT MclNTOSH
Exhaustive testing
and evaluation of each component part makes your C 26 the best value. As an
example- the front panel is constructed of materials that are nearly
indestructible! The combination of anodized aluminum and glass are impervious
to attacks by acids and oils. The subtle beauty of the C 26 will remain
unblemished year, after year, after year. This attention to detail increases
the value of a Mclntosh at trade in time.
FLEXIBILITY IS A
DESIGN REQUIREMENT AT MclNTOSH
Careful attention to
customer needs, attention to changes in customer use, and constant
experimentation in new methods makes the Mclntosh C 26 preamplifier the most
responsive to customer needs. Control of
remote loudspeaker and main system loudspeakers from the preamplifier is a
Mclntosh innovation.
With the C 26 you
can record on one or two tape recorders, monitor either one or record from one
tape recorder to another! A front panel headphone jack for low impedance
headphones allows the enjoyment of programs in total privacy-
Stepped tone
controls, separate in each channel permits the accurate repeatability of
settings for any program source. The Mclntosh developed concentric switches
give maximum flexibility in each channel without unnecessary clutter and
complication.
Continuously
variable loudness compensation allows the exact amount of compensation to suit
your taste at any loudness level. Add high frequency and low frequency filters,
a six-position input selector, seven-position mode selector, center channel
level control, phase control and a balance control that does not affect the
total loudness in the listening room and you have the useful flexibility
Mclntosh has designed in the C 26. Added to these values is the complete
protection from all service cost for three full years and you know why the
Mclntosh C 26 is the best value in a solid state preamplifier, anywhere.
Only Mclntosh offers
a free THREE YEAR SERVICE CONTRACT with each piece of equipment!
You can't pay us to
service your C 26 for the first three years you own it. Both parts and labor
are included in the contract.
