Pro-Ject Phono Box RS2 Phono Preamplifier

1599.00 € (incl. VAT)

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 DECCA equalization. The Phono Box RS2 employs a true fully balanced design principle.

Description

Discrete Circuitry

A discrete circuit is composed of electronic components that are separate, individual devices – also called ‘discrete’ components. These are ‘passive” components (like resistors, capacitors and inductors) as well as ‘active’ ones, in this case, transistors. The opposite of this would be an integrated circuit with operational amplifiers (op-amps) in the signal chain. Countless hours worth of listening tests and years of experience have shown us how to make a neutral, natural, dynamic, and vivid sound. Standard phono pre-amplifiers with integrated circuits have tens or hundreds of components, but discrete designs 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.

Numerous Cartridge Loading Options

No other phono preamp in the world offers the gain flexibility of Phono Box RS2. A huge range from 40dB (voltage amplification by 100x) up to 70dB (voltage amplification by 3690x) is possible. Load impedance can be set on the fly via a potentiometer – a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust impedance during playback and immediately assess the impact of various loading options. By nature, cartridges suffer from small imbalances between the left and right channels. To correct this, Phono Box RS2 also introduces a new feature that is rare in this price category. A potentiometer allows you to adjust to the exact center of the sound stage in a range of 2dB to the left or right.

Fully Balanced

Phono Box RS2 employs a true fully balanced design principle. Balanced transmissions consist of a hot and cold (also called + and -) signal. Both the + and – signal chains effectively carry the same musical information. A truly balanced amplifier can now extract the final musical information out of the +/- signals and subtract (remove) all noise that could potentially be added along with the transmission. In a true, fully balanced amplifier like Phono Box RS2, the + and – sections of both the left and right channels are treated individually, which doubles the amplifier sections as a result.

Split Passive EQ

Phono Box RS2 uses split passive equalization for both its RIAA and DECCA 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 DECCA curve.

About brand

The History

Pro-Ject was founded in 1991, during the onslaught of the compact disc and CD players, with the mission to offer the best analogue experience for reasonable prices. In a time where the digital audio media had been on the rise, and vinyl was declared as outdated and dead, Heinz Lichtenegger kept his belief in the simple but best way to enjoy music – turntables.

Here at Pro-Ject we strive to create astonishing products with impeccable value. We only use the best components for the price and manufacture our handmade goods solely in Europe. With an eye for future trends we are always trying to fit the needs of the market.
