At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The Cambridge Audio 540P-S 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 MM 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 540P-S. Connected using a stereo audio interconnect cable, the
540P-S 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 540P-S MM phono
pre-amplifier features an acoustically damped full metal chassis with a thick
brushed aluminum front-panel.
Moving Magnet (MM) Compatible: The Cambridge Audio 540P-S 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 540P-S 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 540P-S MM phono
pre-amplifier is fitted with a set of stereo RCA inputs to connect your MM
(moving magnet) cartridge turntable.
Audio Output: The Cambridge Audio 540P-S 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 540P-S to a "Phono
Input" on a receiver or amplifier.
Ground Terminal: The 540P-S 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.
External AC Adapter: The Cambridge Audio 540P-S MM phono
pre-amplifier includes an external AC power supply.
- Input: 120V AC, 60Hz
- Output: 12V - 500mA
