Pro-Ject DAC Box E mobile silver

The Pro-Ject DAC Box E mobile is a portable digital-to-analog converter (DAC) designed for audiophiles on the go. This compact technological marvel promises to significantly enhance the sound quality of your mobile devices, delivering a high-fidelity listening experience wherever you are.

Cutting-edge technology in an ultra-compact format

The DAC Box E mobile stands out with its minimalist design and small dimensions. Measuring just 28 x 14 x 69.2 mm, this DAC fits easily in the palm of your hand or in a pocket. Its precisely machined aluminum casing not only gives it an elegant aesthetic but also ensures exceptional durability for intensive daily use.

Despite its miniature size, the DAC Box E mobile is packed with advanced technology. It features a high-quality digital-to-analog converter capable of processing audio signals up to 32-bit/192 kHz. This capability faithfully reproduces the subtlest nuances of high-resolution recordings, offering an exceptionally rich sound experience.

Connectivity designed for mobility

The Pro-Ject DAC Box E mobile is designed to seamlessly integrate into the modern mobile ecosystem. It features a USB-C input, now the standard on most recent smartphones and laptops. This connection ensures optimal compatibility with a wide range of devices, from iPhones and Androids to MacBooks and Windows PCs.

On the output side, the DAC Box E mobile offers a 3.5 mm stereo mini-jack. This universal choice allows easy connection to most headphones and earphones on the market, whether premium or more affordable. While the lack of a balanced output might disappoint some audiophiles with high-end headphones featuring balanced connectors, this decision helps maintain the ultra-compact format and maximum compatibility.

Audio performance that defies its size

Don’t be fooled by its small size—the DAC Box E mobile delivers impressive audio performance. Its frequency range spans from 20 Hz to 20 kHz, covering the entire human audible spectrum. The harmonic distortion rate is kept extremely low, below 0.01% at 10 mW under 32 ohms, ensuring pure and faithful sound reproduction.

The built-in headphone amplifier provides an output power of over 27 mW under 32 ohms. While modest on paper, this power is sufficient to properly drive most headphones and earphones on the market, including some high-impedance models. The signal-to-noise ratio exceeding 110 dB ensures a perfectly silent background, allowing you to fully appreciate the finest details of your favorite tracks.

Seamless integration into your audio ecosystem

One of the standout features of the DAC Box E mobile is its ease of use. Unlike some portable DACs that require external power, this one draws its energy directly from the connected device. This eliminates the need for an internal battery or separate power supply, greatly simplifying daily use.

The DAC Box E mobile’s compatibility extends beyond smartphones and laptops. It can also be used with portable audio players, tablets, and even portable gaming consoles to enhance their sound quality. This versatility makes it an ideal companion for all music lovers who care about audio quality across their devices.

Tailored sound with digital filters

Pro-Ject has equipped the DAC Box E mobile with several digital filters that allow users to subtly adjust the sound signature to their preferences. These filters affect the phase and impulse response of the signal, offering various options to fine-tune the sound output.

Available filters typically include options like “Linear Phase Fast Roll-Off,” “Linear Phase Slow Roll-Off,” “Minimum Phase Fast Roll-Off,” and “Minimum Phase Slow Roll-Off.” Each filter brings its unique touch, whether in terms of temporal precision, harmonic richness, or transient definition. This flexibility allows every user to find the setting that best suits their equipment and personal taste.

An ideal solution to bypass smartphone limitations

With the gradual disappearance of the 3.5 mm headphone jack on many high-end smartphones, the DAC Box E mobile emerges as an elegant solution for users who want to continue using their favorite wired headphones. By bypassing the smartphone’s built-in DAC and amplifier, which are often of average quality, it delivers a significant improvement in sound quality.

This improvement is particularly noticeable when listening to high-resolution audio files or streaming services offering high-quality options like Tidal HiFi or Amazon Music HD. The DAC Box E mobile allows you to fully exploit these high-quality audio sources, revealing details and dynamics that smartphone audio circuits typically cannot reproduce.
