C22 OWNER'S MANUAL INTRODUCTION The C22 Commemorative issue preamplifier and owner's manual are faithful reproductions of the original, produced from 1963 through 1968. A few changes were made to the original preamplifier design to reflect technology ad­ vances and contemporary system requirements. Signal switching has been updated to Elec­ tromagnetic switches. Close tolerance film resistors and polypropylene capacitors add precision to equalizer, filter and tone control cir­ cuits. The tube complement retains the reliable 12AX7A for the amplifying stages. The cathode follower output stages are changed to 12AT7's to allow more current output to drive lower im­ pedance loads. Balanced audio outputs are added to take advantage of the greater noise reduction capabilities of Balanced cables. A built-in headphone amplifier provides head­ phone listening. This preamplifier is dedicated in remem­ brance of the late Frank H. Mcintosh, founder of Mcintosh Laboratory and co-inventor of the Mcintosh Unity Coupled output circuit, which provided the foundation for the forming of the company. Mr. Mcintosh was president of Mcin­ tosh Laboratory, Inc. from its inception in 1949 until his retirement in 1977. GENERAL DESCRIPTION The Mcintosh C22 Stereophonic Preamplifier is a control center for any sterophonic sound system. To increase your enjoyment of stereo music, this control center does four jobs with great precision. First, The control center amplifies weak elec­ trical impulses. Phono signals are amplified 1000 times, while high level signals are amplified 10 times. As a record rotates on the turntable, undulations in the grooves move the pickup stylus approximately one thousandth of an inch, in any direction, from the rest position. From this slight mechanical movement, the pickup stylus generates a weak electrical im­ pulse on the order of a few thoudsandths of a volt. To amplify and preserve the information in such a small electrical impulse, the finest amplifier performance is required. Second, Every sound system is used in a dif­ ferent environment. The tone balance of the music is affected by variations in the environ­ ment. Also, people listening to the music have varying ideas of correct tone balance. To com­ pensate for these conditions, a high-quality tone control center is needed. Third, All stereophonic and monophonic phono records, both domestic and foreign, are record­ ed with specific frequency equalization. The control center must accurately compensate for this equalization introduced in the recording process. Fourth, programs can originate from several sources such as tuners, records, tape recorders, CD players, etc. A control center is needed to select and switch these sources separately, or in combination. All these jobs are performed with excellence by the C22. Once you have enjoyed the outstanding per­ formance of the C22, you will understand why Mcintosh products have earned their reputation as "THE BEST". Your Mcintosh C22 Stereo­ phonic Control Preamplifier will give you years of the finest possible performance, and will become a highly valued part of your home music system. 1
