Box Design Classic Line
The Pro-Ject Phono Box is one of the most popular phono stages on the market today. Combining affordability, simplicity and great sound; it's a simple addition that helps turntables sing.
Boasting a sophisticated internal design that employs low-noise ICs and precise RIAA equalisation circuitry, the Phono Box is often found used with far more expensive turntables. Simply connect the In and Output cables, push the switch to select Moving Magnet or Moving Coil operation (depending on your turntable cartridge), plug it in and off you go.
The small size of the Phono Box allows for discrete placement near your turntable or behind an existing system.

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).
