The most significant factor in the perceived responsiveness of the volume control is the speed at which the knob is being turned. We all naturally tend to move volume knobs more quickly when we need to make a bigger change, and we tend to slow down as we approach our desired volume. Thus, if the CP-700 sees the knob moving relatively quickly, it uses coarse steps to effectively accelerate the action of the circuitry. As the knob begins to turn more slowly, the CP-700 will actually increase the resolution of the steps, which slows down the action of the volume control and yields greater precision in choosing an appropriate setting.

Of course, it is possible to bump into the knob by accident, which might result in its spinning very quickly indeed. Rather than increasing the volume uncontrollably under these conditions, the CP-700 actually slows everything down again as a safety measure against accidentally blowing your speakers. In fact, if you like you may establish a speed limit beyond which the knob will simply be ignored.

The factory default settings for these behaviors are generally found to be intuitive and a pleasure to use. However, if you prefer to alter these behaviors, you may do so in the rotary menu, shown below.

All of the rotary setup settings are interactive. You can set the value, and then adjust the volume to see whether the effect is what you desired.

•low range: determines the degree to which the responsiveness of the volume control is boosted at low volume control settings, in order to get through them more quickly. A setting of 0 disengages the effect, while a setting of 100 maximizes it.

•low speed: determines the responsiveness of the control when the knob is being turned slowly. A setting of 0 will cause the volume to change as slowly as possible at low knob speeds; a setting of 100 will cause the volume to change as quickly as allowed at low knob speeds. (The menu is the same as the one above except for the indication that it is for the “low speed” adjustment.)

cp-700 specifications

The Classe Audio CP-700 is a high-performance audio preamplifier that exemplifies the brand’s commitment to sound quality, design, and innovative technology. Tailored for audiophiles and music enthusiasts, the CP-700 combines superior build quality with advanced circuitry to deliver an immersive listening experience.

One of the standout features of the CP-700 is its robust digital processing capabilities. It includes a high-resolution DAC (Digital-to-Analog Converter) that supports audio formats up to 24-bit/192kHz. This ensures that every detail of the music is reproduced with outstanding clarity and precision. The preamplifier also boasts multiple digital inputs, including USB, coaxial, and optical, making it versatile enough to accommodate various audio sources.

The analog section of the CP-700 is equally impressive, featuring Classe's proprietary technologies that minimize noise and distortion. The preamplifier utilizes high-quality components and a carefully engineered circuit design that embraces a dual-mono architecture. This approach reduces crosstalk and enhances imaging, allowing listeners to experience a wider soundstage and more defined instrument placement.

Moreover, the CP-700 features a state-of-the-art volume control system. Rather than a traditional potentiometer, Classe employs a digitally controlled analog attenuator, providing precise volume adjustments without compromising the audio quality. Users can expect smooth and seamless changes in volume levels, enhancing user experience during playback.

In terms of usability, the Classe CP-700 offers an intuitive interface, with a large, bright display and a user-friendly remote control. The preamp can also be controlled via an app, adding convenience for modern users who prefer controlling their audio systems through mobile devices.

Another notable characteristic is its elegant design. The CP-700 features a sleek aluminum chassis with a minimalist aesthetic that fits well in various home theater or music room setups. This careful attention to design aligns with Classe Audio’s philosophy of marrying form with function.

In conclusion, the Classe Audio CP-700 preamplifier stands out for its high-resolution audio capabilities, advanced volume control, and exceptional build quality. It is an ideal choice for discerning listeners who seek an unparalleled audio experience without compromising on features or aesthetics. With its combination of digital and analog prowess, the CP-700 represents the pinnacle of modern audio engineering.
