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.
