Fully integrated ultralow-loss custom relay RSR-2-12D and naked foil resistor A monster preamplifier for truly live and enjoyable music performances
The output line amplifier uses Type-R discrete non-NFB balance circuits that have been finely tuned for preamplifier use. It also includes the newly-developed super high-quality naked foil resistors. With 1ohm emitter resistors and 3.9ohm output resistance, it delivers astonishing information detail and S/N presence for superior power preamplifier drive capabilities.
The best possible methods and the highest-quality parts create the best audio volume control. All the resistors in this unit are ultra high-quality, naked foil resistors. The switching relays also use the newly developed RSR-2-12D (Reference SOULNOTE Relay) ultralow loss custom relay. Volume control is configured with 144 steps in 0.5 dB intervals. Vibrancy and sound quality remain unaffected, even when lowering the volume.
One major factor affecting sound quality deterioration in preamplifiers is GND loops and noise intrusion when connecting multiple sound sources. One way to eliminate this problem is to adopt a switching method on the GND and signal end so that unselected devices are held in a state where their connectors are unplugged. And to avoid any interference from the relay connection, the selectors in this unit all use the RSR-2-12D.
Temperature settings The circuit current in SOULNOTE products relies on solutions with the highest emphasis on sound quality and safety. Functionality and sound quality generally improve when the transistors operate at higher temperature.。 Anti-vibration housing SOULNOTE products place the highest emphasis on sound quality, so the top cover, chassis, and other components do not employ vibration isolation. Regarding use of electronic equipment cleaners and contact rejuvenation products on SOULNOTE products Commercially available electronic equipment cleaners and contact rejuvenation products could damage the resin components of SOULNOTE AC inlets. Do not use these types of chemical products on SOULNOTE equipment.
