The LD Systems PPA 2 is a very compact analogue phono preamplifier, which equalises the extremely low output signal of conventional turntables to RIAA standards. It allows you to connect to devices without any phono input, such as mixers, PA power amplifiers or sound cards.
The phono inputs are designed as RCA jacks, just like the line outputs; the PPA 2 also has a screw terminal for the ground conductor of the turntable and a 6.3 mm stereo jack for connecting a headset. The THD factor of the preamplifier is below 0.05% and the channel separation is -75 dB.
The LD Systems PPA 2 uses a 12 V AC adapter; a bright LED indicates the power supply on the top of the sturdy metal chassis.
