10DC Trigger Input and Output

Many audio/video components can supply a DC control voltage to associated equipment in order to induce desired behavior. Your Classé preampliﬁer can take advantage of these capabilities in order to be switched between operate and standby automatically, usually in concert with the A/V preamp itself.

The 1/8th-inch mini mono-jack Trigger In provides for remote-controlled turn-on (that is, toggling between operate and standby) of the preampliﬁer.

Two 1/8th-inch mini mono-jacks provide individually controllable DC trigger outputs which can be used for any of a number of purposes, as described in The Menu System. For example, your dealer can program Trigger Out1 to toggle your Classé power ampliﬁer between operate and standby with your CP-700.

The remote trigger input will respond to the presence of 5–12VDC, with tip polarity as shown below:

Similarly, the trigger outputs will create a 12VDC signal that can source up to 100mA of current.

11Ground terminal

The ground terminal on your preampliﬁer is most often used for the ground wire of a turntable, assuming you have the optional phono module installed (see your authorized Classé dealer for more information on this option if you are interested). Connecting the ground wire from your turntable’s tonearm to this screw terminal usually minimizes any hum

or buzzing to which the turntable might otherwise be susceptible. Your authorized Classé dealer can assist you in handling this problem if it should arise.

12DC Power Input

The DC Power Input for the CP-700 is located near the middle of the rear panel. Connect the provided multi-pin “umbilical cord” between the outboard power supply and this connector to provide the preampliﬁer with the clean, pure DC power it needs to do its job.

There is also an AC mains switch on the back of the outboard power supply. Switching the power supply on (assuming the preampliﬁer is connected with the umbilical cord) puts the preampliﬁer in standby mode. The preampliﬁer should also be in standby before power is switched off.

Potentially dangerous voltages and current capabilities exist within your power supply, even when disconnected from AC mains. Do not attempt to open any portion of the unit’s cabinet. There are no user-serviceable parts inside. All service of this product must be referred to a qualiﬁed authorized Classé dealer or distributor.

cp-700 specifications

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.
