The LD Systems PPA 2 is a very compact analog phono preamplifier that equalizes the extremely low output signal of conventional turntables to RIAA standards. It allows you to connect devices without phono inputs, such as mixers, PA amplifiers or sound cards.
The phono inputs are designed as RCA jacks, as are the line outputs; the PPA 2 also has a screw terminal for the turntable's grounding conductor and a 6.3 mm stereo jack for connecting a headset. The preamp's THD factor is less than 0.05% and 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.
