LOUDNESS

Figure 12. LOUDNESS switch.

Use the LOUDNESS switch in the COM- PENSATED position to listen at low volume and still hear full-frequency range. When you turn down the volume, the music will seem to lose much of its bass and some of its treble. This effect is due to the sensitivity character- istics of human hearing. The response of the human ear to bass and treble pitch de- creases more rapidly than its response to notes centered in the midtonal range. The LOUDNESS switch automatically provides the correct amount of bass and treble boost required to compensate for this change in

response of the human ear at low-loudness levels. When the LOUDNESS switch is moved to the COMPENSATED position, it converts the volume control to a loudness com- pensated control.

CONTROLS BEHIND THE FRONT PANEL

Depressing the PANLOC buttons allows the C22 to slide forward to a point approxi- mately 3 inches from the mounting panel. In

this position, additional controls on top of the C22 chassis are available; the PHASE switch,

LOW FREQUENCY TRIM CONTROLS, OUT- PUT LEVEL CONTROLS, TAPE EQUALIZA- TION CONTROLS, and the PILOT LAMP INTENSITY switch.

PILOT LAMP INTENSITY

Use the PILOT LAMP INTENSITY to switch the front panel pilot lamps to DIM or BRIGHT.

TAPE EQUALIZATION

Use the TAPE EQUALIZATION controls to compensate for 3% tape speed for individual tape head characteristics. These controls should be set to NAB for normal 7.5 inch tape speed machines. Turning the TAPE EQUALIZATION controls clockwise increases the treble response; turning them counter- clockwise decreases treble response.

OUTPUT LEVEL CONTROLS

Use the OUTPUT LEVEL controls to bal- ance the overall amplifier-speaker system. The minimum setting on each control re- duces the output level approximately 15 db. The L + R (left plus right) control adjusts only the output from the L + R output jack. This control can turn the L + R signal com- pletely off.

LOW FREQUENCY TRIM CONTROLS

Use these controls to adjust for unequal speaker response at low frequencies due to room location of speakers. Approximately 6 db of boost below 100 cycles is available.

The preamplifier offers both phono and line-level inputs, allowing users to connect a wide range of devices while ensuring the highest quality sound.

The C22 employs a unique vacuum tube circuitry that contributes to its warm and rich tone. The use of vacuum tubes, combined with solid-state technology, provides a sonic character that is both dynamic and detailed. 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.
