Project Phono Box
Today, many amplifiers do not have a specific phono cartridge input. Phono Box is an ideal phono preamplifier for these hifi system and accepts both MM and MC cartridges. The analogue output of Phono Box can easily be connected to a line-input (AUX,…) of your amplifier.
Preamplifier for MM or MC with switch on rear panel
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 recordplayer
