the other the only control that is effective is the TAPE JACK switch. (Note: Some portable tape machines will drive the C22 even though the TAPE JACK switch is in the RECORD

position.) This is not a normal circuit use and a distorted signal usually results. For low- distortion operation follow the recommended procedure.

USING THE C22 WITH MICROPHONES FOR STEREO

Microphones in stereo may be used with the C22. The two MIC channels amplify microphone signals. They have a sensitivity of 2 millivolts and an input impedance of 1 megohm. For lower output microphones in- put transformers should be used to raise the

voltage output to the 2 millivolt range.

When the INPUT SELECTOR is turned to the MIC position, the COMP control does not operate. All the other controls operate and may be used the same as for any other program source.

This hybrid design results in a smoother frequency response and adds depth and warmth to the music, making it particularly appealing for listeners who enjoy vinyl records.

Another characteristic feature of the C22 is its analog volume control, providing precise adjustments to sound levels without introducing unwanted noise that often comes with digital controls. The preamplifier’s tone controls allow users to tailor the sound profile to their personal preference, enhancing the listening experience for various musical genres.

In terms of technology, the McIntosh C22 supports high-quality audio formats, equipped with balanced and unbalanced outputs for seamless integration with power amplifiers. This ensures that the integrity of the audio signal is maintained throughout the audio chain. The C22 also incorporates the proprietary McIntosh Autoformer technology that guarantees consistent performance, regardless of the connected equipment's impedance.

The build quality of the C22 is another highlight. Enclosed in a striking chassis with a classic glass front panel, the preamplifier features an iconic blue meter display, which not only serves a functional purpose but also adds to its aesthetic appeal. The craftsmanship is complemented by high-end components that promise durability and longevity.

Overall, the McIntosh C22 stereo preamplifier stands as a testament to the blend of vintage elegance and contemporary high-fidelity technology. Its distinctive sound signature, extensive connectivity options, and robust construction make it an essential component for anyone serious about achieving an exceptional audio experience. Whether you are a dedicated audiophile or a casual listener, the C22 delivers a sonic performance that resonates with the soul of music.
