Description: 1: Support 4 way stereo audio inputs one way output2: with remote control: Power on/off choose input Adjust volume Mute3: Rotate the Right one selector knob is choose inputs. press the selector is standby.Rotate the left knob is adjust the volume Using 2pcs Shuguang 12AX7 + 2pcs 12AT7 tubes / or 2pcs PSVANE ECC83 +2pcs PSVANE ECC81Hi end Oxygen-free copper R-core transformerOriginal Japan ALPS Potentiometer.Taiwan high quality frosted Pure copper RCA terminals.Full aluminum chassis + Stainless steel switchThis preamp is reference the famous Matisse preamp Circuit , using High voltage 400V power supply, parallel Tubes, the first stage is 12AX7 and the second stage is 12AT7. this much better than most other lower voltage Matisse preamp Clone Circuit. PRT06B preamp design thinking:1: It is consistent with the 400V power supply voltage of the original machine.2: All voltage parameters are consistent with the original machine.3: DC filament power supply to avoid the influence of voltage fluctuation on the filament4:The output signal is switched on with time delay to avoid the strange sound generated by the electron tube when the engine is hot This preamp sound is very comprehensive and dynamic. The human voice is naturaland delicate, the strings are smooth, stretched, and the positioning and imaging are excellent. The high and low frequencies are extended inplace, and the low frequencies dive deep and powerful without lack of flexibility.There are many tube preamp on the Internet design is not very reasonable. The main manifestation is that the distance between the Tubesis too close. ZERO-ZONE suggests that the distance between the centerof each is greater than 40mm.● Gain: about 10 times.● input impedance:47K● SNR: 90dB;● Frequency response: 10Hz--30KHz;● Distortion: ≤1%● Size:362*98*340MM (W*H*D)Package include:Finished preamp X 1Remote X1 (no battery)Default is not include any cables.
