INSTRUCTIONS FOR USE Pro-Ject Phono Box S2
Dear music lover, thank you for purchasing a Pro-Ject Audio Systems phono amplifier. In order to achieve maximum performance and reliability you should study these instructions for use carefully. Warning of a hazard for the user, the unit or possible misuse. Important notice. Safety instructions AC outlet voltages vary from country to country. Before connecting to the mains, make sure that the voltage in your area meets the voltage requirements printed on the power supply.
Input impedance / input capacitance – high-output MC and MM cartridges Input impedance – low-output MC cartridges * Input capacitance is irrelevant for low-output MC cartridges Input gain Subsonic filter A switch at the back of the phono amplifier activates and deactivates the subsonic filter. © Pro-Ject Audio Systems · Pro-Ject Phono Box S2 · Revision 2017.8.
Connectors Make all connections whilst the phono amplifier is disconnected from the power supply. Take care to connect the left and right channels correctly. The right channel is usually marked red, the left channel black or white. Do not connect the phono amplifiers output to a phono input (sometimes labelled gram, disc or RIAA) on the amplifier. Never use any other power supply than the one supplied with the unit.
