C22 STEREO PREAMPLIFIER

GENERAL DESCRIPTION

The Mclntosh C22 Stereophonic Pream- plifier is a control center for any stereophonic sound system. To increase your enjoyment of stereo, this control center does four jobs with precise control.

First, the control center amplifies weak electrical impulses. As the 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 impulse on the order of a few thousandths of a volt. To amplify and pre- serve the information in such an electrical impulse, the finest amplifier performance is required.

Second, every sound system is used in a different acoustical environment. The tone balance of the music is affected by variations in environment. Also, people listening to the music have varying ideas of correct tone bal- ance. To compensate for these conditions, a high-quality tone control center is needed.

Third, all stereophonic and monophonic records, both domestic and foreign, are recorded with specific frequency equaliza- tion. The control center must accurately com- pensate for this equalization introduced in the recording process.

Fourth, programs can originate from sev- eral sources such as tuners, records, tape machines, microphones, etc. A control center is needed to select and switch these sources separately or in combination.

All of these jobs are performed with excel-

lence by the C22.

The C22 also uses the new, exclusive Mclntosh PANLOC method of installation. The PANLOC system gives you absolute ease of installation, operation, and maintenance. PANLOC is the first professional installation technique to be used on stereo instruments.

In the PANLOC system a metal shelf is mounted first, then the preamplifier slides into position on this shelf. Depressing the PANLOC buttons on the front panel locks the preamplifier firmly into place for normal operation. To unlock the preamplifier, de- press the front panel PANLOC buttons a second time. The preamplifier can now slide forward to the ADJUST position. The pre- amplifier will lock in this position approxi- mately 3 inches from the mounting panel. Now you can adjust the output level controls, low frequency trim controls, tape equaliza- tion controls, phase switch and pilot lamp intensity switch. These controls are mounted just behind the C22 front panel. Depressing the ADJUST position holding latches on the sides of the chassis allows the preamplifier to be taken out of the PANLOC shelf, or to slide back into position against the mounting panel.

Once you have enjoyed the outstanding performance of the C22, you will understand why Mclntosh products have earned their reputation as "THE BEST." Your Mclntosh C22 Stereophonic control preamplifier will give you years of the finest possible perform- ance, and will become a highly valued part of your home music system.

TECHNICAL DESCRIPTION

The C22 Stereophonic Preamplifier com- bines excellence in performance with ease of operation. The most often used controls have large diameter knobs. A new type of rocker switch is used for the controls with simple on-off functions. The C22 has an illuminated front panel with a light intensity switch to

provide convenient reading under low-level lighting conditions. The Mode and Input Selector switch positions are also illuminated.

The C22 circuit consists of 3 amplifier sections in duplicate for the left and right stereo channels together with a common power supply. The first amplifier section is
