Overview: The Cambridge Audio 551P MM phono pre-amplifier has been
designed to complement a wide range of entry-level MM (moving magnet) turntables. This high-quality
pre-amplifier contains the amplification required to enable you to connect your
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 551P.
Connected using a stereo audio interconnect cable, the 551P 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 551P MM phono pre-amplifier
features an acoustically damped full metal chassis with a thick brushed aluminum
Moving Magnet (MM) Compatible: The Cambridge Audio 551P is a
Moving-Magnet-type (MM) phono stage; which describes the commonly used type of
cartridge (sometimes referred to as a "needle" or "stylus") configuration
typically supplied with affordable modern turntables.
Class A Amplification: The 551P 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.
MM Phono Input: The Cambridge Audio 551P MM phono pre-amplifier is
fitted with a set of stereo RCA inputs to connect your MM (moving magnet)
Audio Output: The Cambridge Audio 551P MM 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 551P to a "Phono
Input" on a receiver or amplifier.
Ground Terminal: The 551P 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.
Power Switch: The Cambridge Audio 551P 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 551P MM phono pre-amplifier
includes an external AC power supply.
- Input: 120V AC, 60Hz
