Cambridge Audio CP1
Phono preamplifier for moving magnet cartridges (Silver)
Our take on the Cambridge Audio CP1 by Crutchfield's Dave Bar
The CP1 adds excitement and life to the sound of your vinyl records.
Improve your standards of listening
Do you really need a separate phono preamplifier? The simple answer is, of course, if your turntable or stereo system doesn't already have one built in. But even if does, and you're currently plugging your turntable directly into your receiver or amp's phono input, you could still be missing out on a lot of sonic goodness. That's because many manufacturers use low-cost, low-fi circuitry that sounds flat and lifeless.
The Cambridge Audio CP1 solves that problem. It boosts and equalizes the tiny voltages coming from your 'table's moving magnet phono cartridge to deliver a robust, line-level signal infused with rich, dynamic sound — revealing layers of musical detail hidden in the grooves of your favorite vinyl records.
The Cambridge Audio difference
Cambridge Audio has a passion for creating high-value audio gear that captures every last drop of detail and emotion from your music. The CP1 has been carefully designed to offer plenty of foot-tapping performance at a price that won't break the bank. Its advanced electronics include high-quality 'Class A' amplification circuits and hand-picked components housed in an all-metal outer casing featuring a thick, brushed-aluminum front panel. And since Cambridge knows that not every phono cartridge delivers perfectly even left- and right-channel output signals, they gave this preamp a fine-tune balance control that lets you correct for any differences.

Thanks for submitting your review
Phono Pre-Amp: The Cambridge Audio CP1 phono pre-amplifier has been designed to complement a wide range of MM (moving magnet) turntables. This high-quality pre-amplifier contains the amplification required to enable you to connect your MM turntable to your integrated amplifier, stereo receiver, or home theater receiver. Some integrated amplifiers and receivers are already able to support turntable connections, but these built-in phono pre-amplifiers are out-performed by the Cambridge Audio CP1. Connected using a stereo audio interconnect cable, the CP1 is set-up in minutes allowing you to appreciate stunning clarity, musicality, and resolution from all your vinyl recordings.
Moving Magnet (MM) Compatible: The Cambridge Audio CP1 is a phono pre-amplifier with a moving magnet (MM) input stage; which describes the commonly used type of cartridge (sometimes referred to as a "needle" or "stylus") configuration typically supplied with many turntables.
"Class A" + RIAA EQ: The CP1 MM phono pre-amplifier utilizes a single-ended "Class A" gain stage with audiophile passive RIAA equalization for excellent sound quality.
Discrete Transistors: The Cambridge Audio MM phono pre-amplifier uses discrete transistors for the input stages, instead of the more common integrated circuits which can cause interference and distortion. The CP1 using premium components chosen for exceptional accuracy, amplifying the signal without distorting it.
Balance Control: The CP1 MM phono pre-amplifier offers Balance Control for fine correction of cartridge imbalance. This control allows you to make fine adjustments to the relative output levels of the left and right channels. In the central position the output from each channel is equal.
RCA Input/Output: The Cambridge Audio CP1 MM phono pre-amplifier is fitted with a set of stereo RCA inputs to connect your MM (moving magnet) cartridge turntable. The CP1 is also fitted with a set of stereo RCA outputs to connect your turntable and the pre-amplifier to the line-level inputs on your home receiver or integrated amplifier.
Note: Do not connect the CP1 to a "Phono Input" on a receiver or amplifier.
Ground Terminal: The CP1 has a turntable ground, in case your turntable has a separate ground lead. This provides shielding to the tone-arm and the sensitive circuitry in the turntable.
All Metal Chassis: The Cambridge Audio CP1 phono pre-amplifier features an acoustically damped full metal chassis with a thick brushed aluminum front-panel.
Power Switch: The Cambridge Audio CP1 features a front-panel power switch to turn the unit On/Off; this allow energy consumption to be zeroed when not in use.
External AC Adapter: The Cambridge Audio CP1 MM phono pre-amplifier includes an external AC power supply.
- Input: 120V AC, 60Hz
- Output: 12V - 500mA
