{"product_id":"pj97826473","title":"Pro-Ject Phono Box RS2 Black Preamplifier (pj97826473)","description":"\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003eDiscrete Circuitry\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eA discrete circuit is composed of electronic components which are disparate, individual devices, also called discrete components. These can be “passive” components, like resistors, capacitors and inductors, as well as “active” components, which in our case are transistors. The opposite to this would be an integrated circuit, which uses operational amplifiers (Op-Amps) in the signal chain. Countless hours of listening tests and years of experience have shown us that even the very best Op-Amps do not tend to be so neutral, natural, dynamic or vivid. Standard phono pre-amplifiers with integrated circuits have a few tens or hundreds of components, but discrete designs will employ hundreds or thousands of components by comparison. That makes for an extended and more costly design process, but results in the best sound for your money.\u003c\/p\u003e\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003eFully Balanced\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eThe Phono Box RS2 employs a true fully balanced design principle. Balanced transmissions consist of a hot and a cold (also called + and -) signal. Both the + and – signal chains effectively carry the same musical information. A true balanced amplifier can now extract the final musical information out the +\/- signals and subtract, remove, all noise that could potentially be added along the transmission. In a true, fully balanced amplifier, like the Phono Box RS2, the + and – sections of both the left and right channel are treated individually, which doubles the amplifier sections by 2 as a result.\u003c\/p\u003e\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003eSplit passive EQ\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eThe 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. Split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA or DECA curve.\u003c\/p\u003e\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003eExtreme cartridge loading options\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eNo other phono-preamp in the world has such fine options of setting the gain like the Phono Box RS2. Very large ranges from 40dB (voltage amplification by 100x) up to 70dB (voltage amplification by 3690x) are possible.\u003c\/p\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eLoad impedance can be set continuously via potentiometer, a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust the impedance during playback and immediately assess the impact of different loading options.\u003c\/p\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eCartridges, by nature, suffer from small imbalances between the left and right channels. To correct this the Phono Box RS2 introduces a new feature that is absolutely rare in this price category. A potentiometer allows you to adjust the exact center of the sound stage in ranges of 2dB to the left or right.\u003c\/p\u003e\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003eSteel\/aluminium chassis\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eThe Phono Box RS2 has a steel chassis which is covered by screwed aluminium panels. This construction brings very good rigidity and splendid isolation against interferences.\u003c\/p\u003e\u003ch3 class=\"MuiTypography-root jss365 MuiTypography-subtitle1\"\u003ePower Box RS2 Phono – linear power supply upgrade\u003c\/h3\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eAn 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. Obviously, such a transformer becomes larger than one would expect. Also, much more expensive. That is why such a power supply requires a cabinet the size of the Phono Box RS2 itself. Our Power Box RS uni 1- \u0026amp; 4-way will be another step up for your Phono Box RS2 performance.\u003c\/p\u003e\u003cp class=\"MuiTypography-root jss366 MuiTypography-body1\"\u003eMM \u0026amp; MC
