PRODUCT INFORMATION Reference class phono preamplifier with unique impedance control The Phono Box RS2 is the ultimate phono preamplifier of the highest class. It is fully balanced from the input to the output. Electronics are fully discrete, no op-amps are in use and it uses split passive RIAA and DECA equalization. An EQ has to be handled and implemented very carefully and split passive EQ is the most expensive way to do it, but also the only way to go if you want the most accurate sound.

PRODUCT INFORMATION cuit board, twice as many electrical components and be twice as careful with planning your circuit board layout. As a result, the Phono Box RS2 excels at suppressing unwanted noise, errors and interferences and offers the best signal to noise ratio possible. Split passive EQ The Phono Box RS2 uses split passive equalization for both of its RIAA and DECA curves. This is more costly to design and implement but ensures the most accurate representation of the ideal EQ curve.

PRODUCT INFORMATION Power Box RS2 Phono - linear power supply upgrade An outboard power supply with linear construction is even better, because it can offer much cleaner power. When you want to manufacture such clean and really high-end power supplies, you have to use a transformer with a very low core saturation and preferably with shielding between primary and secondary windings. Low core saturation decreases radiation of the outer electromagnetic field which can be inducted into sensitive circuitry.
