Part of Radio Design Labs' "Stick-On" series, the ST-PH1 mountable turntable preamp provides accurate, low-noise preamplification at a very reasonable cost, connecting phono-level-output turntables with any equipment. Features: balanced and unbalanced, high and low-z outputs with level controls for left and right output; total harmonic distortion from 10 Hz to 30 kHz is <0.03% with hi-z load and <0.015% with 600 ohm load; equalization follows RIAA curve; small enough to stick on the back of your turntable base. Connections thru screw terminals.
