Overview
The Pro-Ject Pre Box S2 Analogue is a stereo preamplifier that stands out for its fully analog design, ensuring faithful and natural reproduction of the audio signal. With high-quality components and an advanced circuit, this preamplifier delivers a neutral sound with an extremely low noise floor. The total harmonic distortion (THD) of just 0.0005% highlights the purity of the signal, providing an exceptionally clear listening experience.
The extended frequency response from 20 Hz to 40 kHz (+0 - 0.5 dB) reproduces the entire audible spectrum and beyond, capturing even the subtlest nuances and harmonics of your music. The 8.5 dB gain offers balanced amplification, preserving the dynamics and details of your favorite recordings.
Versatile Connectivity for Seamless Integration
The Pre Box S2 Analogue excels in connectivity versatility. Equipped with three line inputs, including two pairs of RCA connectors and a 3.5 mm jack input, it accommodates a wide range of audio sources. Whether you want to connect a CD player, tuner, or portable device, this preamplifier has you covered.
On the output side, the Pre Box S2 Analogue features a variable RCA output for connection to a power amplifier, as well as a fixed 3.5 mm output ideal for driving headphones or a second amplifier. Additionally, a 12V trigger output allows for synchronized power-on with other compatible devices, simplifying the operation of your audio system.
Compact and Refined Design
Despite its impressive performance, the Pre Box S2 Analogue boasts an ultra-compact design measuring just 103 x 36 x 120 mm. This minimalist design fits effortlessly into any environment while offering a sleek aesthetic with finishes available in black or silver.
The aluminum/metal sandwich casing is not just for looks—it effectively shields the internal circuits from electromagnetic interference and vibrations, preserving audio signal quality. Every detail has been carefully considered to optimize performance, including the use of SMD (Surface Mounted Device) technology to shorten signal paths and minimize losses.
Ease of Use and Flexibility
The Pre Box S2 Analogue doesn’t compromise on practicality. Featuring a motorized volume control, it provides enhanced precision in adjusting sound levels. The included infrared remote control allows you to manage essential functions such as power, input selection, and volume from a distance.
The supplied 5V/1A external power supply ensures optimal operation, but the preamplifier can also be powered by a 5V external battery, offering appreciated installation flexibility. With a standby power consumption of less than 1W, it reflects a commitment to energy efficiency.
Accessible Audiophile Advancement
The Pre Box S2 Analogue continues Pro-Ject’s tradition of delivering excellent value for money. It represents a significant step forward compared to previous models, offering audiophile-grade performance at an affordable price. Its build quality, component selection, and technical specifications place this preamplifier on par with much more expensive models.

Frequently Asked Questions
Can I use the Pre Box S2 Analogue with a turntable?
The Pre Box S2 Analogue does not have a built-in phono input. To use a turntable, you will need an external phono preamplifier before connecting your turntable to one of the line inputs on the Pre Box S2 Analogue.
Is the Pre Box S2 Analogue compatible with home theater systems?
While primarily designed for stereo systems, the Pre Box S2 Analogue can be integrated into a home theater setup as a preamplifier for the main left and right channels. However, it does not support multichannel audio formats.
What is the difference between the variable and fixed outputs?
The variable output allows volume adjustment via the preamplifier’s control, making it ideal for connection to a power amplifier. The fixed output maintains a constant signal level, perfect for driving headphones or a recording device.
Does the Pre Box S2 Analogue require a break-in period?
As with many high-end audio devices, a break-in period can slightly enhance performance. Typically, around 50 hours of use is sufficient for the components to reach their full potential.
Can the Pre Box S2 Analogue be used as a headphone amplifier?
The Pre Box S2 Analogue is not designed as a dedicated headphone amplifier. For optimal headphone use, it is recommended to pair it with a separate headphone amplifier connected to its fixed output.
