Overview: The Cambridge Audio 651P phono pre-amplifier has been
designed to complement a wide range of MM (moving magnet) and MC (moving coil) turntables. This high-quality
pre-amplifier contains the amplification and electronic circuitry required to enable you to connect your
MM or MC
turntable to your stereo amplifier or home theater receiver. Some
amplifiers are already able to support turntable connections, but these built-in phono pre-amplifiers are out-performed by the Cambridge Audio 651P.
Connected using a stereo audio interconnect cable, the 651P is set-up in minutes
allowing you to appreciate stunning clarity, musicality, and resolution from all
your vinyl recordings.
All Metal Chassis: The Cambridge Audio 651P phono pre-amplifier
features an acoustically damped full metal chassis with a thick brushed aluminum
MM (Moving Magnet) & MC (Moving Coil) Compatible: The
Cambridge Audio 651P is MM (Moving Magnet) & MC
(Moving Coil) Compatible. The 651P phono pre-amplifier is fitted with a set of stereo RCA inputs to connect your MM (moving magnet) turntable, and a set of stereo RCA inputs to connect your MC (moving coil)
turntable. There is a MM/MC switch on the rear-panel to select which type of turntable you have.
Class A Amplification: The 651P phono pre-amplifier utilizes a
single-ended "Class A" gain stage with audiophile passive RIAA equalization
and multi-parallel capacitors to achieve exceptional RIAA accuracy of only
0.3dB, up to 50kHz.
Discrete Transistors: The Cambridge Audio phono pre-amplifier uses
discrete transistors for the input stages, instead of the more common integrated
circuits which can cause interference and distortion.
Audio Output: The Cambridge Audio 651P is 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. Do not connect the 651P to a "Phono
Input" on a receiver or amplifier.
Ground Terminal: The 651P 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.
Subsonic Filter: The 651P features a subsonic filter to remove the
unwanted and disruptive effects "rumble" of low-frequency energy caused by vinyl
Power Switch: The Cambridge Audio 651P 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 651P phono pre-amplifier
includes an external AC power supply.
- Input: 120V AC, 60Hz
- Output: 12V - 500mA
