Dear friends,

SoulNote P-3 Preamplifier is @ Audio Basic !

We have setup it together with our SoulNote system and in the process of running in. Performance is remarkable even though it's just out of box !

For more updates, follow our Facebook page https://www.facebook.com/audiobasic

SoulNote P-3 Preamplifier has awarded by:
** Stereo Sound Grand Prix Award 2020
** MJ Technology of the Year Award 2020

Monster preamplifier that plays music organically and enjoyably.

* Adopting Type-R circuit for non-feedback balance amplifier
The output line amplifier is equipped with a discrete non-feedback balance circuit "Type-R circuit" that made a brilliant debut with S-3, fully tuned for the preamplifier.
In addition, a newly developed ultra-high precision naked foil resistor is introduced. By setting the emitter resistance to 1Ω and the output resistance to 3.9Ω, it demonstrates an amazing amount of information, SN feeling, and power amplifier-class drive capability.

* High-end fixed resistance switching type volume
The best volume was born by the best possible method and the best parts. Ultra-high precision naked foil resistors are used for the resistors. Also, for the switching relay, we have newly developed and adopted the ultra-low loss custom relay RSR-2-12D (reference soul note relay). The volume of 144 steps is composed of 0.5dB steps. Even if the volume is turned down, the freshness is not lost and the sound does not lose weight.

* About RSR-2-12D (Reference Soul Note Relay)
Further customization based on the ultra-low loss glass tube sealed reed relay that demonstrates performance close to that of mercury relay. This is our original custom relay that has been driven to a level that is comparable in sound quality to wires. P-3 uses 94 of these relays per unit.

* Ultra-high-precision naked foil resistance Based on

the artificial satellite-grade ultra-high-precision foil resistance with excellent temperature characteristics, we are particular about sound quality and further customize it. In order to eliminate dumps and habits caused by molds and dips, we have made it naked and independently developed a resistor with the highest sound quality. The P-3 uses 156 of these resistors per unit.

* GND switching method
One of the biggest factors that deteriorate the sound quality of the input selector preamplifier is the problem of GND loop and noise mixing due to connecting a large number of source devices. In order to eliminate this problem, we adopted a method of switching not only the signal side but also the GND so that the unselected device is in a state where the connector is unplugged. Moreover, in order to avoid the influence of a relay contact, RSR-2-12D is fully adopted as a selector.

* Complete twin monaural construction
For the left and right channels, we have adopted a so-called twin monaural construction that uses two identical input / output terminal boards, circuit boards, power supply circuits, power transformers, relay drive circuits, and relay power supplies. Moreover, the power supply for the microcomputer is also completely separated including the transformer. Furthermore, the control signal of the relay, which is the only contact with the signal system, is completely separated by a photocopier.

* Complete separation of GND
By having three chassis insulated with ceramics for each of the three systems of the left and right channels and the control system, each of the three GNDs of the left and right GND and the control system GND is completely separated. I succeeded in making it. It is possible to connect each GND by setting the rear switch, but by completely separating the GND, you can experience the amazing phenomenon that "the sound field spreads surprisingly three-dimensionally and all sounds start to sing organically". increase.

* Ultra-powerful power transformer
The analog power transformer uses a large non-impregnated toroidal transformer with 280VA on each side. Including the control transformer, it has the strongest capacity in SOULNOTE history, which is equivalent to A-2 with a total of 600VA. As for the transformer, the audible drive capability improves in proportion to the increased regulation brought about by the large capacity. The driving force of P-3 changes the grade of the power amplifier and the speaker.

* Vertical mounting of the transformer By making the mounting direction of the transformer perpendicular to the board, the direction of harmful leakage flux is made parallel to the board, and it is prevented from jumping into the circuit.

* Double bearing & flywheel type optical rotary encoder
The flywheel effect of the large volume knob made of solid aluminum and the two large bearings used to eliminate mechanical backlash make the volume control feel moist, heavy and supple. Won.

* Non-fixed AC inlet base
The AC inlet uses JODELICA ETP-600CU. In addition, by not mechanically fixing the aluminum AC inlet base, dumping of the rear panel was prevented and a more open sound quality was obtained.

* Three-point spike grounding
Three spikes directly connected to each of the three power transformer bases eliminate harmful vibrations of the transformer before it propagates to the chassis.

* Floating structure
The Type-R board and top cover have a floating structure that is not mechanically fixed. By being released from mechanical stress and harmful air dump effects, we have acquired a vivid and natural sound quality and sound field that is close to the state where the top cover is open.

* GND anchor
The left and right side metals are insulated from the main chassis by ceramic washers, and the left and right GND are directly connected. This further enhances the effect (a vast sound field and transparency) due to the floating left and right GND.

* Specifications
