Balanced P2

Balaned P2 Tubes Phono Stage Eq-Preampilier

Balanced P2, phono stage embodies the newest thinking of YS-audio dedicated and enthusiastic technical design YS Chui . The unit has MC input ( Max 68.25dB of gain ) and MM input ( Max 48,5dB of gain ), and, just as importantly, the Balanced P2 boasts an low noise level, so in practical use, the 75.5dB gain is usable in systems with low overall sensitivity. It uses a 6X4 rectifier tube with solid state regulator for HV B+ power supply , three 12AX7 for the gain stage and two 5687WA/B drive Jensen output transformer consist output stage provide true balanced output. Jensen MC step-up transformer provide true balanced input .This MC step-up transformer can good match for 1.5ohm ~ 40ohm output Impedance of MC cartridge . MM input is 47K ohm. The Balanced P2 all hand made by "point-to-point" .

Features

uncanny natural flowing heart-stirring sound that
matches any other ultra-Fi products on the market .
The phono stage made by Hand built " point to point " on YS-Audio factory.
"point to point" has become more focused, the soundstage is deeper.
Hand built by " point to point ' is very high cost of manufacture !
The installation of the tubes line stage is special designed , it can prevent RF interfere and vibrate interfere,
It has become very clean soundstage and saw the musical instrument hang up in the air.

The HV B+ power supply is application of a highly efficient solid-state voltage regulator with 6X4 Tube for current buffer.
The 6X4 Tube opens up the soundstage and allows the music to "bloom". The melody flows naturally, like a river.
The highly efficient solid-state voltage regulator give the very good bass controls .

The Important features

The Balanced P2 has a select control for select 4 kind phono EQ network :
RIAA , London ffrr , Columbia , SP.

The RIAA EQ for prevalence LP ,
The London ffrr EQ for London ffrr LP ,
The Columbia EQ for Columbia and old NAB LP ,
The SP EQ for EU 2 Single-Play.

The Balanced P2 has two pair MC input with both RCA and XLR , one pair RCA for MM input .
The output with both RCA and XLR

Jensen MC step-up transformer provide true balanced input .
This MC step-up transformer can good match for 1.5ohm ~ 40ohm output Impedance of MC cartridge.

Phase select switch Normal / Inverse
Gain select switch with 6 position : 1 is MC 68.25dB / MM 48.5dB , 2 is MC 67.25dB / MM 47.5dB , 3 is MC 66.25B / MM 46.5dB , 4 is MC 63.75dB / MM 44dB , 5 is MC 61.75dB / MM 42dB , 6 is MC 57.75dB / MM 38 dB

The two 5687WA/B drive Jensen output transformer consist output stage provide true balanced output.

External power supply.

All RCA connections use Neutrik , coupling cap use Sonicap and Oil cap.
