Pro-Ject Record Box E White Preamplifier

Pro-Ject Black High End Preamplifier

The Pre Box RS2 Digital is the bigger brother of our award winning and ground breaking Pre Box S2 Digital. It uses the same excellent sounding DAC chips as the S2 version, proving once again that the Pre Box S2 Digital was already at the very top of high-end DACs and absolutely beyond its competition. Based on the same core-design principles, the feature set is extended and driven to new heights. The result is a fantastic sounding and very versatile box. The perfect partner for the cream of the crop of high-end amplifiers and speakers alike!

The Pre Box RS2 Digital is a DAC and preamplifier that uses a dual-mono configuration of the highest-class D/A converters from ESS Sabre. ESS9038Q2M chips provide the highest sound quality in price-affordable, high-end circuits. Unlike most of DAC´s in this price range, the Pre Box RS2 Digital includes dual DACs and separate signal paths for the left and right channels. Also thanks to these converters, the Pro Box RS2 Digital supports up to 32-bit / 768 kHz files in PCM and DSD formats (up to DSD512) via USB, covering any digital file you can buy or stream.

The analog output is a buffer that is both solid state and high-quality tube. Thus, the customer can choose which of the option is preferred. The Pre Box has eight digital filters. One of them is the proprietary optimal transient digital filter from the MQA creators. With these filters, the listener can customize the sound to suit their own preferences. Pre Box RS2 Digital comes with full HW and SW support for MQA technology (Master Quality Authenticated).

In the Pre Box, the USB input signal is processed by a powerful multi-core XMOS microcontroller with advanced Multi-Core RISC architecture. The CPLD MAX II (Complex Programmable Logic Device) Altera is used for re-clocking, which together with the XMOS microcontroller brings high-quality processing of both classical and MQA technology. For the ideal use of this technology, it is best to connect the Pre Box to our Stream Box S2 Ultra in conjunction with the TIDAL service. You can also enjoy MQA quality by linking it with our new revolutionary CD transport, the CD Box RS2 T. The CD Box RS2 T can be connected to the Pre Box by reliable I²S differential bus via the HDMI connector where the Pre Box RS2 Digital also provides the master clock (16.9344 MHz).

The headphone amplifier is the ultimate design. No compromise. No coupling capacitors. Not even on the output. All of the the amplifier is DC coupled. A very fast DC servo assures no DC voltage on the output. Its output power is suitable for all kind of headphones.

A premium full aluminum remote control is included in the packaging and the Pre Box RS2 Digital is available in a high-quality silver or black aluminum case. The big display screen on the front shows all relevant information in an easy to read, clean and structured way. Navigating the menu is very responsive and fast, allowing you to set up the unit to your preferences in seconds!

Pro-Ject Silver Phono Preamplifier

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.

Pro-Ject Black Phono Preamplifier

A 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.

The 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.

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. Split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA or DECA curve.

No 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.

Load 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.

Cartridges, 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.

The 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.

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. 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- & 4-way will be another step up for your Phono Box RS2 performance.

Fully discrete hardware design - NO Op-amps!

Balanced XLR & unbalanced RCA In & Outputs

Unique continuously variable input impedance loading and channel balance control to match every cartridge to 100% (adjustment even while playing)
