The Phono Box DS+ is an ultra-low-noise phono pre-amplifier that benefits from outstanding circuit technology designed by Dr. Sykora. It is also the first affordable phono stage to allow for quick and easy setup via a high-quality display panel. The Phono Box DS+ does away with the need for fiddly dip-switches or jumpers by putting all setup options onto a screen, with all adjustments made by an intuitive set of buttons on the unit.
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.
The Phono Box DS+ is designed with carefully selected amplifier modules, premium contact relays and audiophile-grade polypropylene capacitors, which guarantees a warm analogue sound, a rich soundstage and a hugely involving performance.

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