Pro-Ject Phono Box Phono Pre-Amp

Most of today’s amplifiers are built without a specific phono cartridge input. The Phono Box is an ideal phono preamplifier for these hi-fi systems, accepting both MM and MC cartridges. The analogue output of the Phono Box can easily be connected to the line-input of your amplifier.

• Preamplifier for MM or MC with switch on rear panel
• Best buy classic
• “Green” DC power supply (< 1 watt standby power)
• Precise RIAA equalisation
• Low noise ICs
• Output stage with ultra-low impedance
• Gold-plated RCA sockets
• Small size for installation near record player
