  • phono preamp designedĀ to connect analog sound sourcesĀ to systems w/ no analog inputs (home cinema receivers, sound-bars)
  • can also be used as an input expander for a system w/ shortage in inputs
  • can also be used as anĀ  ordinary MM phono preamp with 3.5mm line output, orĀ to digitize phono and line level analog sources (tape deck, tuner, etc.)
  • analogue RCA and digital optical output work simultaneously, can be used as aĀ signal splitter to play the same signal on (2) systems simultaneously
  • 1 phono (RCA stereo pair) + 1 line level (3.5mm stereo jack) input
  • 1 line out (RCA stereo pair) + 1 optical output
  • precise RIAA equalization
  • low-noise circuitry
  • internal metal shielding eliminates RF interference + vibrations
  • outboard power supply included
  • handmade inĀ Europe

"Anyone who wants to useĀ their record player together with devices with digital inputs only, such as home cinema receivers, sound-bars or all-in-one systems will love this little box. The Optical Box E Phono takes many needs into account and offers a digital-optical signal output plus a standard analogue output that will work simultaneously. Therefore it can be used as the perfect signal splitter 1>2 to play the same signal on 2 systems at the same time. Another very useful purpose of Optical Box E Phono is that it can act as an input expander, for a system with shortage in inputs. Last but not least Optical Box E Phono is able to digitize not only phono sources, but also line signals from tape decks, tuners etc. To ensure that the incoming signal is maintained as unadulterated as possible, the A/D conversion in highest precision with 24bit / 96kHz resolution. Of course it can also be used as an ordinary MM phono preamp with line output (3.5mm jack) that integrates in any HiFi system." -Ā Pro-Ject
