Specifications:
The Hafl er PH50 is a high performance phono preamp for moving magnet (dynamic) cartridges that delivers 35 dB of gain while incorporati ng a well defi ned RIAA curve to preserve and transmit the original program material with minimal colorati on. Parti cular att enti on has been applied to reducing noise, a problem com-mon to the 33 RPM recording chain, resulti ng in a low -80 dB noise fl oor with greater than 91 dB of dynamic range and less than 0.002% distorti on.
The design begins with a 14 gauge steel casing to shield the low level signals from external magneti c fi elds and RF contaminati on. Gold-plated RCA input and output connector pairs are employed that will not tar-nish over ti me, thus opti mizing signal fl ow. Inside, the solid-state circuit and military grade PC board has been opti mized by carefully positi oning parts for minimal self-noise and cross-talk and then supplemented with a ground plane to reduce suscepti bility to RF. An external supply further reduces emissions by remov-ing the power transformer from inside the casing.
Front panel controls include a power on-off switch and a variable low-cut fi lter that may be inserted into the signal path when needed. The fully adjustable low cut (high-pass) fi lter enables the user to att enu-ate low frequencies that can cause resonance and feedback when playing music at higher levels. This helps eliminate both airborne and solidly coupled vibrati ons that can enter the stylus and cause feedback, rumble and distorti on.
