DS-Line

The Phono Box DS is an ultra-low-noise phono pre-amplifier that benefits from the same outstanding circuit layout of the superior Phono Box DS+. The Phono Box DS is essentially a stream-lined version of its more advanced sibling.

Compared to the DS+, the Phono Box DS does not have the screen or the same gold-contact relay-switching; but it does benefit from a more attractive price and an equal focus on user-friendliness. For the first time, nearly all setup options can be made via a simple button/led indicator on the front panel, avoiding the need for miniature dip-switches or jumpers.

This popular member of the iconic Phono Box range offers exceptional performance and maximum flexibility for almost any MM or MC Cartridge available, making the DS an instant market leader considering its attractive price and stylish design. The carefully selected amplifier modules and audiophile-grade capacitors then guarantee a breath-taking sound experience.

A subsonic filter, that prevents your amplifier and speakers from suffering with ultra-low rumble below 20Hz, is also positioned on the rear panel. 

Key Features:

  • Audiophile-Grade Components and Performance 
  • SMD Circuitry 
  • Ultra Low Noise & Low Level Distortion
  • Linear RIAA Equalization 
  • Switchable Subsonic Filter
  • Switchable Input Impedance / Capacitance / Gain

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)
