Pro-Ject BT Box S2 HD silver

The BT Box S2 HD is the latest addition to Pro-Ject’s range of high-definition Bluetooth receivers. This compact little device promises to elevate the wireless listening experience to audiophile levels by combining the latest Bluetooth transmission technologies with Pro-Ject’s renowned expertise in high-fidelity audio.

Cutting-Edge Wireless Connectivity

The BT Box S2 HD features Bluetooth 5.0 technology, offering greater range and bandwidth compared to previous versions. This upgrade ensures more stable and higher-quality audio transmission, even when the source is far from the receiver. The device supports several advanced audio codecs, including aptX, aptX-HD, and SBC, ensuring optimal compatibility with a wide range of transmitting devices.

The use of the aptX-HD codec is particularly appealing to audiophiles. It enables the transmission of high-resolution audio streams, preserving maximum sound detail. Even in cases of temporary drops in Bluetooth connection quality, the BT Box S2 HD is designed to maintain high audio performance, avoiding the compression artifacts often associated with wireless transmissions.

A Perfect Blend of Digital and Analog

Pro-Ject has leveraged its expertise in designing turntables and hi-fi electronics to optimize the analog section of the BT Box S2 HD. The device includes a high-quality buffered analog output stage, specifically designed to ensure a robust and stable connection with amplifiers and speakers.

This focus on the analog signal section sets the BT Box S2 HD apart from standard Bluetooth receivers. It delivers more faithful and musical sound reproduction, preserving the dynamics and nuances of the original audio signal.

Easy Integration into Any Audio System

Despite its advanced performance, the BT Box S2 HD remains simple to install and use. It features a quick auto-pairing function, allowing up to 8 different Bluetooth sources to be stored in memory. This flexibility makes it an ideal companion for users who want to easily share their music from various devices.

In terms of connectivity, the BT Box S2 HD offers both a stereo RCA analog output and a Toslink optical digital output. This versatility allows it to integrate seamlessly into virtually any existing audio system, whether it’s a traditional hi-fi setup or a more modern home theater system.

High-Performance Audio

The BT Box S2 HD doesn’t just provide convenient wireless connectivity; it also aims to satisfy the most demanding audiophiles. Its extended frequency response from 20 Hz to 20 kHz ensures faithful reproduction of the entire audible spectrum. The signal-to-noise ratio of over 85 dB and low harmonic distortion (less than 0.1% on the line output) guarantee clear and precise audio signal reproduction.

The BT Box S2 HD’s ability to deliver a nominal output level of 2 Vrms ensures optimal connection with most amplifiers, providing adequate sound volume without compromising audio quality.
