The Reference Phono 2 is a fully balanced design with an input circuit that allows its RCA inputs to operate in a balanced configuration without requiring an inverter. The feature set of the Reference Phono 2 is extensive. There are two separate sets of inputs, with gain selectable between Low (51dB BAL / 45dB SE) and High (74dB BAL / 68dB SE). There is a choice of seven loading selections including 47K, 1000, 500, 200, 100, 50 ohms, and Custom, which we can factory-set according to your need. (If not specified, the Custom load is 47K.) In addition to standard RIAA phono equalization, the Reference Phono 2 also includes early stereo Columbia and Decca equalization curves. The display will show all selected functions (Input, Gain, Loading, EQ, Mute, Tube Hours), and its intensity can be adjusted to one of six levels, plus off. When the display is off, nine small pixels will remain lit in the center as a discreet reminder that the unit is powered on-touch any button, and the display comes on for ten seconds. The microprocessor will remember the independent settings for each input, and the supplied remote will control all of these functions.
