Sound processor to connect to every music source. By grinding the signal over a 12au7 tube, the sound becomes an experience that is otherwise only known from a tube amplifier. Through a glass window on the front, this converter becomes a real eye -catcher when glowing the tube. The TPR-2 can also be used as a phono preamplifier in conjunction with MM and MC sampling systems. Volume control, line/phono switch, separate voltage supply (including). Technical information: reinforcement = (mm) 40 db / (MC) 60 db / (line) 12 dB, input resistance = (mm) 47 KOHM / (MC) 100 Ohm / (line) 20 KOHM, output resistance = 7 KOHM, frequency response = mm and MC depend on use of the pickup / (line) 20 KHz (+/- 0.2 dB), Rausal distance = (mm) -68 dB / (MC) -70 db / (line) -76 db.
