The CP-700 preamplifier is set at the factory for 100V, 120V, 220V, 230V, or 240V AC mains operation, as appropriate for the country in which it is to be sold (230V only in European Union countries, in compliance with CE regulations). The voltage setting may not be changed by the user.

Make sure that the label on the rear panel of your preamplifier indicates the correct AC operating voltage for your location. Attempting to operate your preamplifier at an incorrect voltage may damage the unit.

The voltage setting of your preamplifier may not be changed by the user. There are no user-serviceable parts within the unit. Please refer any problems to an authorized Classé service center.

If the AC mains voltage indicated on your preamplifier is incorrect, please contact your local, authorized Classé dealer or distributor.

The CP-700 can easily be powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account.

The CP-700 includes protection circuitry that will prevent the preamplifier from operating at dangerously high or low voltages.

•At startup: the AC mains voltage must be within a range of approximately -15% to +10% of its nominal value at startup, or the preamplifier will not turn on. For example, a 120V unit requires the AC mains to be between approximately 95V–135V in order to turn on.

•Over-voltage during operation: if the AC mains voltage surges by roughly 10% or more during operation, the preamplifier will enter protection mode and shut down. The Standby LED will flash to indicate the protection mode has been engaged.

•Under-voltage during operation: if the AC mains voltage sags by 15% or more, the preamplifier will continue to play (since this does not present a particular danger to the amplifier), but note that it may not be able to achieve its usual standard of performance under these compromised conditions. The Standby LED will flash to indicate the condition.

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.
