The LD Systems PPA 2 is an extremely compact analogue Phono preamplifier that equalizes the extremely low output signal of conventional turntables to the RIAA standard. It enables connection to devices without a phono input, e.g. mixing consoles, PA power amplifiers or sound cards.
Like the line outputs, the phono inputs are designed as RCA sockets; the PPA 2 also has a screw terminal for the turntable's ground conductor and a 6.35 mm stereo socket for connecting headphones. The distortion factor of the preamplifier is less than 0.05% and the channel separation is -75 dB.
The LD Systems PPA 2 is operated with the associated 12V power adapter, a bright LED indicates the power supply on the top of the sturdy metal housing.
