Phono Stages

551p_main_2280x510

Azur 551P

DESIGNED FOR PURITY

There’s something uniquely pleasurable about listening to vinyl, something that digital media can’t reproduce in quite the same way. However most hi-fi amplifiers won’t let you plug in a turntable directly. You need to connect via a phono stage (also known as a phono preamp) to make the very small signal from the turntable powerful enough for your main amp to work with. But it’s very easy to add noise at this stage, which is why we have designed the 551P using premium components chosen for exceptional accuracy, amplifying the signal without distorting it or introducing noise.

COMPATIBILITY

The 551P works with all popular turntables that use a Moving Magnet cartridge (the stylus or needle). For a high-end audiophile turntable with a Moving Coil cartridge see the Azur 651P premium phono stage which works with both types.

MOVING MAGNET VS MOVING COIL

The 551P is a Moving Magnet type (MM) phono stage, which describes the commonly used type of cartridge configuration typically supplied with affordable modern turntables.

DO I REALLY NEED A SEPARATE PHONO PREAMPLIFIER?

Some amplifiers are already able to support turntable connections but these in-built phono preamplifiers are massively out-performed by the 551P and we believe that any serious vinyl lover will immediately hear the benefits! Connected using a single audio interconnect cable, the 551P is set up in seconds allowing you to appreciate stunning clarity, musicality and resolution from all your vinyl recordings.

Azur 651P

DESIGNED FOR PURITY

There’s something uniquely pleasurable about listening to vinyl, something that digital media can’t reproduce in quite the same way. However most hi-fi amplifiers won’t let you plug in a turntable directly. You need to connect via a phono stage (also known as a phono preamp) to make the very small signal from the turntable powerful enough for your main amp to work with. But it’s very easy to add noise at this stage, which is why we have designed the 651P using premium components chosen for exceptional accuracy, amplifying the signal without distorting it or introducing noise.

COMPATIBILITY

The 651P works with all turntables, whichever type of cartridge they use. Like the 551P it works with popular Moving Magnet cartridges. But it also works with Moving Coil cartridges found in the highest-end audiophile turntables offering even more accuracy and detail than Moving Magnet. Additionally, even if your amplifier does have a built-in phono stage, it’s well worth bypassing using the 651P to deliver much greater depth and detail of audio.

ADVANCED AMPLIFICATION

Audio circuitry has been refined with multiple transistors wired in parallel ensuring the lowest possible distortion and noise. A copper shield provides further protection to this extremely sensitive part of the circuitry, limiting the noise that can be injected into the signal. This is especially important with a Moving Coil cartridge because its signal is even quieter and more delicate than Moving Magnet, so it needs even more amplification.

PREMIUM COMPONENTS

High-spec multi-parallel capacitors achieve exceptional RIAA accuracy – the industry standard for reproducing vinyl recordings. While a highly accurate, subsonic filter removes the common problem of unwanted low-frequencies that are inaudible but can damage subwoofers.

TOTAL POWER OFF

In line with Cambridge Audio’s commitment to the environment, a power switch cuts energy consumption to zero when not in use.
