Box Design Classic Line

The Phono Box USB V boasts the same great quality performance as the iconic Phono Box, except now with the addition of a high-quality A/D converter!

Now, at the same time as listening to your music through your traditional hi-fi, you can record your vinyl to a computer or laptop; giving you the ability to play the same music on-the-go through a portable digital audio player. The volume dial on the front panel allows for full control over the gain of your USB signal, which can help avoid distorted or 'clipping' recordings.

The Phono Box USB V also benefits from a Line input, allowing you to record Line-Level sources, such as a tape deck, to your computer as well.

Key Features:

  • Metal case shields the electronics from external interference. 
  • Small size allows installation close to record player. 
  • Special low-noise ICs used. 
  • Optimal channel separation through dual-mono circuitry. 
  • Gold plated RCA connection sockets. 
  • Outboard power supply included. 
  • Amplification and RIAA equalisation for MM and MC cartridges
  • Phono MM/MC selection switch located at the rear of the unit 
  • Works with a wide variety of audio recording programs to transfer your vinyl 
  • Driver-less connection method for simple set-up
  • Runs on Windows® and Mac OS® operating systems

What is the Line Input for?

The Line Input is there to allow for recording from a Line level device, such as a Tape Deck, to a computer via USB. It should not be used as a play-through input for your normal hi-fi system, as the Gain applied will distort the sound. The RCA outputs are only for use with the Phono Inputs.

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).

Can I play my turntable through my computer/laptop using USB without recording?

To play records in Audacity without recording, make sure 'software playthrough' is enabled in the Transport menu, then right click the right-hand recording VU meter with the microphone symbol, which turns on "monitoring". Click in the meter again if you want to turn monitoring off.
