Pro-Ject Phono Box S2 black
Overview
The Pro-Ject Phono Box S2 is a phono preamplifier designed for vinyl enthusiasts. As the successor to the popular Phono Box S, this model delivers enhanced audio performance and increased versatility, all housed in a sleek and compact design.
A Refined Design Combining Aesthetics and Functionality
The Phono Box S2 features a clean, modern design that blends seamlessly into any audio setup. Its one-piece silver anodized aluminum casing not only provides a premium look but also improves shielding against electromagnetic interference and unwanted vibrations. The minimalist front panel includes a stylish blue LED and a discreet power button.
With compact dimensions of 103 x 37 x 119 mm, the Phono Box S2 fits easily into any hi-fi setup, even in tight spaces. Its weight of 570 g ensures excellent stability, which is key to optimal acoustic performance.
Exceptional Versatility to Suit Any Setup
One of the standout features of the Phono Box S2 is its ability to adapt to a wide range of phono cartridges. Compatible with both moving magnet (MM) and moving coil (MC) cartridges, it offers unmatched flexibility in its price range.
Micro-switches located underneath the device allow precise adjustment of the following settings:
- Gain: 40, 43, 60, or 63 dB
- Load capacitance: 100, 200, 320, or 420 pF
- Load impedance: 10 Ω, 100 Ω, 1 kΩ, or 47 kΩ
This high level of versatility enables you to optimize the preamplifier’s performance based on the specific characteristics of your cartridge, ensuring the best possible sound reproduction.
Exceptional Sound Quality to Elevate Your Vinyl Experience
The Phono Box S2 stands out for its remarkable audio performance, delivering precise, detailed, and dynamic sound reproduction. Its fully dual-mono internal architecture ensures optimal stereo separation and a highly accurate soundstage.
High-quality components, such as WIMA polypropylene capacitors, contribute to the purity of the audio signal. The high-precision RIAA equalization (20 Hz - 20 kHz / max. 0.4 dB) ensures faithful reproduction of the sound spectrum.
The high signal-to-noise ratio (85 dB for MM cartridges, 68 dB for MC cartridges) and low harmonic distortion (0.01% MM / 0.05% MC) reflect the meticulous design of this preamplifier.
Practical Features for Optimal Use
The Phono Box S2 includes several features that enhance its everyday usability:
- A switchable subsonic filter (-12 dB at 20 Hz) eliminates unwanted low frequencies, particularly useful for warped records or turntables sensitive to vibrations.
- The external 18V DC / 500mA power supply reduces interference and improves the signal-to-noise ratio.
- Low power consumption (85 mA, < 1W in standby) makes it an energy-efficient device.
Significant Upgrades Over the Previous Model
The Phono Box S2 introduces several notable improvements over its predecessor, the Phono Box S:
- A one-piece anodized aluminum casing for better shielding against interference.
- Higher-quality internal components for improved audio performance.
- Greater flexibility in gain, capacitance, and load impedance settings.
- A refreshed design that aligns with Pro-Ject’s new aesthetic line.
These upgrades make the Phono Box S2 an even more compelling choice for audiophiles seeking a high-performance and versatile phono preamplifier.

Frequently Asked Questions
Is the Phono Box S2 compatible with all turntables?
The Phono Box S2 is compatible with the vast majority of turntables on the market, whether equipped with MM or MC cartridges. Its flexible settings allow it to adapt to almost any configuration.
Can I use the Phono Box S2 with an integrated amplifier that has a phono input?
While not necessary, you can use the Phono Box S2 with an amplifier that has a phono input. In this case, make sure to disable the amplifier’s phono stage or use a standard line input to avoid double preamplification.
How do I determine the optimal settings for my cartridge?
Refer to your cartridge’s specifications to find the recommended values for gain, capacitance, and load impedance. You can then fine-tune these settings by ear to achieve the best sound quality.
Does the Phono Box S2 require a warm-up period to reach optimal performance?
Unlike tube preamplifiers, the Phono Box S2 does not require a long warm-up period. However, like any electronic device, its performance may slightly improve after a few minutes of operation.
Can the Phono Box S2 be used to digitize vinyl records?
Yes, you can use the Phono Box S2 in conjunction with an analog-to-digital converter to digitize your vinyl records. Simply connect the output of the Phono Box S2 to the input of your converter to achieve an optimal signal.
