Details:
◆ Customized 50VA pure copper tape shielded R-Core transformer
◆ With volume remote control and signal source switching function, 2 XLR balanced inputs, 2 RCA single ended inputs, 1 XLR balanced output, 1 RCA single ended output, it is suitable for a wider range.
◆ Capacitor array is used for high-voltage power supply, which has lower internal resistance of power supply and stronger dynamic transient; At the same time, the high-voltage MOS power regulator is used together, which has the smell of electronic tubes and does not produce annoying noise of electronic tube rectification and voltage stabilization.
◆ The left and right channel DC filament is supplied with independent voltage stabilization, pure and free from crosstalk.
◆ Audiophile resistor+capacitor assembly, a new benchmark of electronic tube preamplifier.
◆ All aluminum chassis, high-end sandblasting technology, beautiful and luxurious.
6N11 is used as cathode output in the output stage, ECC82 common cathode is used for voltage amplification in the first stage, and constant current diode is used as cathode constant current in the first stage. The output of the machine can be balanced and single ended, and the input also can be balanced and single ended.
Input voltage: AC 115V or 230V (For choose)
Using tubes: 2 PCS Beijing 6N11 and 2 PCS PSVANE ECC82
Input port: 2 Groups Balance XLR and 2 Groups Single ended RCA
Ouput port: 1 Groups Balance XLR and 1 Groups Single ended RCA
Size: 423mm*90mm*308mm (W*H*D) Not include the Size of knob and RCA protrusion.
Package weight: About 7.7KG
Input impedance: 470K
Maximum input voltage: balanced 5VPP, single terminal 2.4VP.
◆ Buyer also can update with other better tubes, 6N11=6922=6DJ8 ECC82=12AU7 ◆
Package include:
PRT-13A-BAL Full balance tube preamplifier X 1
Remote controller X 1 (No Battery included)
NOTE : When input Single ended audio. only single ended output, No XLR output. We do not provide any cables.
