Pro-Ject Phono Box E black

The Pro-Ject Phono Box E is a compact and affordable phono preamplifier designed for vinyl enthusiasts. This small device allows you to connect a turntable to an amplifier or active speakers that lack a dedicated phono input.

An Essential Phono Preamp for Your Turntable

The Pro-Ject Phono Box E fulfills two crucial functions for playing vinyl records. First, it amplifies the low electrical signal generated by the turntable’s cartridge to a level suitable for a standard amplifier. Second, it applies the necessary RIAA equalization to restore the frequency balance altered during the record cutting process.

This preamplifier is compatible with moving magnet (MM) cartridges, which are found on most consumer turntables. With a gain of 40 dB, an input impedance of 47 kOhms, and a capacitance of 120 pF, it perfectly matches the characteristics of these cartridges. The Phono Box E allows you to fully exploit the potential of your turntable, delivering a balanced and detailed sound.

Thoughtful Design for Optimal Performance

Despite its ultra-compact size, the Pro-Ject Phono Box E makes no compromises on build quality. Its metal casing includes internal shielding to effectively protect against electromagnetic interference. The electronic components are surface-mounted (SMD) to minimize noise and distortion to remarkably low levels.

The included external power supply also helps maintain signal purity by reducing potential interference. Gold-plated connectors ensure optimal and durable contact. Thanks to these smart technical choices, the Phono Box E achieves a signal-to-noise ratio of 88 dB and total harmonic distortion below 0.04%.

Easy Integration into Your Audio System

With its compact dimensions of 120 x 32 x 100 mm and lightweight design at just 250 g, the Pro-Ject Phono Box E fits discreetly into any setup. It can be placed close to the turntable to minimize the length of sensitive cables. Its operation requires no complex adjustments: simply connect it between the turntable and the amplifier to immediately enjoy its benefits.

The preamplifier features a pair of RCA inputs for connecting the turntable and a pair of RCA outputs to link to a line input on the amplifier (AUX, CD, etc.). A front-mounted on/off switch allows you to put it in standby mode when not in use, with power consumption dropping below 1 watt.

Audiophile Sound Performance

Despite its attractive price point, the Pro-Ject Phono Box E delivers sound quality comparable to more expensive models. Its RIAA equalization accuracy between 20 Hz and 20 kHz (+0.5/-0.2 dB) ensures faithful reproduction across the entire audible spectrum. Low frequencies are rendered with depth and definition, while highs remain refined without harshness.

The soundstage created by the Phono Box E is characterized by its width and stability. Instruments are clearly positioned in space, enabling an analytical listening experience. The preamplifier also preserves the dynamics and micro-details present in the grooves, revealing the full richness of high-quality vinyl pressings.

Unbeatable Value for Money

By offering audiophile performance at a very affordable price, the Pro-Ject Phono Box E stands out as a benchmark in its category. It allows beginners to enjoy high-quality playback without a significant investment. For more experienced audiophiles, it serves as an excellent starting point for building a vinyl setup or upgrading an existing system.

The simplicity and reliability of the Phono Box E also make it a practical choice for everyday use. Its robust construction ensures long-lasting durability, while its versatility allows it to pair with a wide range of turntables and amplifiers.
