Classic, versatile preamp The Pro-Ject Phono Box DC is a classic, versatile sound-first design that is an undeniable bargain. First and foremost, it’s designed to preampflify the phono signal in a clear, low-noise fashion with impressive depth & imaging for a stage in this class. Top-notch circuitry minimizes distortion and heightens RIAA equalization accuracy for gorgeous analog reproduction with MM or MC cartridges. Wide compatibility Push-button selection between 40db gain (MM, 47k ohm load) and 60dB (MC, 100ohm load) makes Phono Box DC widely compatible, representing a fantastic introduction to the world of moving coil cartridges. Specs Input capacitance/input impedance, MC: 100ohms/120pF A Input capacitance/input impedance, MM: 47kohms/120pF B Gain, MM / MC: 40dB / 60dB Output voltage typically, MM / MC: 300mV at 1kHz - 3mV (MM Input) / 0,3mV (MC input) Max. output: 9,5V (1kHz) Noise floor, MM / MC: 94dB (A weighted) / 75dB (A weighted) THD, MM / MC: 0,01 / 0,05% RIAA-equalization curve accuracy: 20Hz - 20kHz / max. 0,5dB Input: 1 pair RCA/phono sockets Line-level output: 1 pair RCA/phono sockets Outboard power supply: 18V/500mA DC, suitable for your country's mains supply Power consumption: 80mA DC Dimensions W x H x D (D with sockets): 103 x 36 x 104 (115)mm Weight: 570g without power supply
