Primare R32 Phono Stage Preamplifier


The R32 Phono Preamplifier provides the ideal interface between the low-level output of a cartridge and the line-level inputs of your hi-fi system. For sonic excellence and low noise, Primare’s signature dual-mono design philosophy has been applied wherever possible, using the optimum mix of discrete lead-free components from the best semiconductor suppliers. Superior tantalum and low-impedance capacitors are employed throughout the design. The R32 accepts either moving-magnet (MM) or moving-coil (MC) cartridges. Gain and impedance can be adjusted to match virtually any cartridge with the preamplifier. When using a low-output moving-magnet cartridge, an additional 5dB increase in gain is available by fitting an internal jumper. The mains transformer is of the R-core type, recognized for its low noise and minimal magnetic leakage. To further provide protection for the sensitive signal circuits from any possible interference, a shield-plate protects the sensitive amplification components from the transformer, which is placed in the corner of the cabinet opposite of the signal-carrying circuits. The transformer includes separate windings for left and right channel supplies (dual mono design), which are then rectified and individually regulated in order to provide the different voltages required by the R32. Output and input RCA connectors are gold plated and have Teflon insulation to preserve the quality of the delicate low-level signal from the cartridge. The R32 includes a relay controlled mute circuit for silent power on and off.
