Pro-Ject Record Box E black

The Pro-Ject Record Box E is a versatile phono preamplifier designed for vinyl enthusiasts. This compact device provides a complete solution for connecting a turntable to a modern audio system and digitizing your cherished records.

A Phono Preamp with Multiple Talents

The Record Box E is, first and foremost, a high-quality phono preamplifier. It amplifies the low signal produced by the turntable’s cartridge and applies the necessary RIAA equalization to achieve a balanced sound. Compatible with both MM (Moving Magnet) and MC (Moving Coil) cartridges, it works with most turntables on the market.

Its circuit, inspired by Dr. Sykora, uses audiophile-grade components and SMD (Surface Mounted Device) construction to keep noise and distortion at extremely low levels. Internal shielding and an external power supply further help preserve signal purity.

But the Record Box E doesn’t stop there. It also features an analog-to-digital converter and a USB output, making it easy to digitize your vinyl collection on a computer. This is a valuable feature for archiving your records or listening to them on portable devices.

Audiophile Performance at an Affordable Price

Despite its entry-level price, the Record Box E delivers audiophile-worthy performance. It offers a gain of 40 dB for MM cartridges and 60 dB for MC cartridges, with a signal-to-noise ratio of 94 dB and 75 dB, respectively. Total harmonic distortion remains below 0.01% for MM and 0.05% for MC.

The RIAA equalization curve accuracy is impressive, with a maximum deviation of only 0.5 dB between 20 Hz and 20 kHz. The Burr Brown PCM2904 16-bit A/D converter supports sampling rates of 32, 44.1, and 48 kHz.

These technical specifications translate into detailed and natural sound reproduction, respecting the richness of vinyl records. The Record Box E extracts the maximum amount of information from the grooves without adding unwanted coloration.

Simple and Efficient Digitization

One of the main advantages of the Record Box E is its ability to digitize vinyl records via USB. Compatible with Windows, macOS, and Linux, it is automatically recognized by the computer without requiring additional driver installation.

The built-in A/D converter produces audio files in CD quality (16-bit / 44.1 kHz) or slightly higher (16-bit / 48 kHz). Simply use recording software like Audacity to capture the sound from your vinyl and create digital files.

This feature not only allows you to archive your collection but also to enjoy it on modern devices like smartphones or wireless speakers. It’s a great way to give your favorite records a second life.

A Successful Evolution

The Record Box E is an improved version of Pro-Ject’s previous model. It retains the strengths of its predecessor while introducing some welcome refinements.

Compatibility with MC cartridges has been added, significantly broadening its usability. Performance has been optimized, particularly in terms of signal-to-noise ratio and RIAA curve accuracy.

The ergonomics have also been improved, with a more compact design and more accessible connections. Build quality remains excellent, with carefully selected components and meticulous assembly.

Frequently Asked Questions

Can the Record Box E be used with any turntable?
Yes, it is compatible with most turntables equipped with MM or MC cartridges. Simply set the switch on the back to match the cartridge type.

Do I need to install drivers to use the USB function?
No, the Record Box E is automatically recognized by Windows, macOS, and Linux. No additional drivers are required.

Can I listen to the vinyl while digitizing it?
Yes, the line output remains active during USB recording. You can monitor the sound in real-time on your audio system.

What’s the difference between MM and MC cartridges?
MM (Moving Magnet) cartridges are the most common, offering a higher output signal. MC (Moving Coil) cartridges generally provide better sound quality but require greater amplification.

Is the Record Box E suitable for a first vinyl setup?
Absolutely, it’s an excellent choice for beginners. It delivers great performance at an affordable price and allows for upgrades to high-end cartridges in the future.
