Description

2-Line

The original Phono Box S was an international success, combining unrivalled sonics and versatility at a very affordable price. The Phono Box S2 has taken that established design but improved on the sound performance even further. 

The Phono Box S2 boasts a sound field with incredible micro-details, dynamics, precision and clearly defined space. By retaining the original models gain, capacitance and impedance adjustments its possible to get this incredible sound performance with almost any modern cartridge - whether it's a Moving Magnet (MM) or Moving Coil (MC) type.

The new S2 casing is a big additional asset to the improved design, as not only does it deliver the highest visual appeal, but it is also sturdy enough to protect the internal circuitry against unwanted interferences and vibrations, which can cause unpleasant listening experiences.

The Phono Box S was considered one of the best options for entry-level phono stages, the Phono Box S2 is designed to set new improved standards at the same price point.

FAQ

 

What is a Phono Stage?

A phono stage takes the low-level electrical signal, generated by the pick-up cartridge on your turntable, and amplifies it to LINE level. When it's at LINE level, you can connect the outputs of your phono stage to any LINE or AUX input on your amplifier. If you do not have a phono stage, when you connect the turntable to your amplifier the signal will be very quiet, and if you turn it up to normal listening level it will sound distorted and noisy. 

You do not need an external phono stage if...

  • There is a phono stage already built-in to your turntable (for instance with our Phono USB or RecordMaster turntables from Pro-Ject)
  • Your amplifier has a Phono input.

In both of these cases, the built-in phono stage needs to support your pick-up cartridge (see below).


Do I need a specific type of Phono Stage?

Yes. You need to buy a phono stage that suits your particular type of cartridge. If you have a Moving Magnet (MM) cartridge, you need an MM-compatible phono stage. If you have a Moving Coil (MC) cartridge, you need an MC-compatible phono stage. This is due to the different output levels of MM and MC cartridges (as MC cartridges are so quiet, they require more Gain).


What do all of the Setting adjustments mean?

Cartridges are complex micro-mechanical devices, and the way a phono stage treats the electrical signal they generate can dramatically impact the end sound quality. When setting adjustments are available, the one adjustment you always need to check, regardless of the cartridge, is Gain. The level of Gain directly affects all cartridges, as the ultimate task of a phono stage is to amplify the electrical signal.

After Gain, the type of Settings you need to adjust are dependent on the cartridge used...

  • For Moving Magnet (MM) cartridges, you need to adjust the capacitance (measured in pF).
  • For Moving Coil (MC) cartridges, you need to adjust the Impedance (measured in Ω).

Some phono stages have other Settings available, which are not cartridge dependent. For example...

  • Curve Selection (most phono stages are designed with RIAA equalisation in mind, but there are other options available - such as DECCA)
  • Sub-Sonic Filter (to attenuate the low-end out of a system where boom is a problem)
