Atoll Electronique Internal phono module P50 MM

Atoll Electronique P50 MM Internal Phono Module

The Atoll Electronique P50 MM internal phono module is an expansion card that transforms an auxiliary input into a dedicated phono input. Perfect for vinyl enthusiasts, it allows certain Atoll amplifiers and preamplifiers to be adapted without the need to invest in an external phono preamp.

Compatible with a wide range of models (IN50, IN80, IN100, IN200, IN300, IN400, PR100, PR200, PR300), the P50 MM is easy to install, whether at the time of purchase or later. Once installed, it converts an “AUX” input into a “PHONO” input, enhancing the device’s connectivity options.

Technology Serving Musicality

At the heart of the P50 MM is a low-noise JFET operational amplifier, specifically designed for moving magnet (MM) cartridges. This technology ensures precise and faithful amplification of the signal delivered by the phono cartridge while maintaining minimal noise levels. The result is pure and detailed sound reproduction, essential for fully appreciating the warmth and unique character of vinyl recordings.

Technical Performance That Meets Expectations

The P50 MM module boasts impressive technical specifications that reflect its high-quality design. With an input impedance of 47 kΩ, it pairs perfectly with the majority of MM cartridges on the market. Its input capacitance of 100 pF contributes to a balanced frequency response, while its 40 dB gain ensures optimal amplification of the phono signal. The total harmonic distortion (THD) of just 0.05% guarantees faithful sound reproduction without unwanted coloration.

An Attractive Price-Performance Ratio

Positioned as the entry-level option in Atoll’s phono card lineup, the P50 MM offers excellent value for money. It is an ideal solution for beginner audiophiles or those looking to explore the world of vinyl without a significant investment. Its performance is particularly well-suited to entry-level and mid-range turntables, allowing users to get the best out of their equipment without compromising on sound quality.

Flexibility and Scalability at the Core of Atoll’s Philosophy

The ability to add the P50 MM module perfectly illustrates Atoll Electronique’s modular and scalable approach. This flexibility allows users to adapt their equipment to their evolving needs and musical preferences. For those looking to go further, Atoll also offers the P100 card, a more advanced option that provides compatibility with MC cartridges and advanced configuration options.

A Discreet Design for Seamless Integration

The P50 MM has been designed to integrate invisibly into the host device. Once installed, the card does not alter the external aesthetics of the amplifier or preamplifier. This visual discretion is complemented by meticulous electronic integration, ensuring that adding the module does not affect the overall performance of the device but rather enhances it.
