Project Phono Box RS2

ProJect Phono Box RS2 is a necessary device for high-end enthusiasts and professionals looking to fit their turntable and cartridge perfectly so that they can hear the rest of the system with a turn of excellence. It is an entirely discrete device. It is a completely balanced dual-mono system with split passive RIAA and DECCA equalisation, which results in a phono stage developed to produce the best sound ever.

Project Phono Box RS2

On account of its many features, it is able to serve absolute signal integrity and class-leading electrical design; nevertheless, it does not create a barrier to users who only require the most excellent sound from the vinyl hi-fi system.

The top quality of the sound is easily accessible to purists, and tech enthusiasts and experts will get the best high-tech phono stage they are looking for—the Phono Box RS2 is the most suitable solution.

What is the Phono Box RS2?

The Phono Box RS2 is the penultimate-class phono preamplifier, fully balanced from the input to the output. It uses no op-amps and, therefore, has fully discrete electronics. It also uses split passive RIAA and DECA equalization. EQ should be handled carefully, and split passive EQ is the most expensive, but it is also the only way to get the most accurate sound.

Why You Need It

The Phono Box RS2 employs an authentic, 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 properly balanced amplifier can now extract the final musical information from the +/- signals and subtract all noise that could be added along the transmission.

How It Works

Split passive equalization is the choice for Phono Box RS2 to set both RIAA and DECA curves. The method requires more design expenses and is challenging to execute. However, it ensures the most precise imitation of the ideal EQ curve in all cases. Thanks to its lower transmission loss, the split passive equalization provides perfect impedance matching with no huge deviations from the RIAA or DECA curve.

Features and Benefits

• Compatibility: Phono Box RS2 is an automatic system supporting MM and MC cartridges. Making it suitable for different types of turntable setups.
• Technology: Use advanced circuits to reduce unwanted noise in the music for clear, high-quality sound.
• Adjustable Settings: Adjust settings like gain and loading. And impedance to match the cartridge perfectly.
• Channel Separation: Each channel is designed separately. This feature aims to prevent interference between them and consequently improve virtual space.
• High-Quality Build: Produced with top-of-the-line materials. To ensure a long and reliable life cycle and high performance.

Technical Specifications

• Compatibility: It is compatible with both mm and mc cartridges.
• Gain Adjustments: The User can choose for all varieties, MM and MC.
• Impedance Adjustments: The impedance adjustment depends on the cartridge used and varies. So the user can change it as needed.
• Capacitance Adjustments: The user can change or add the low input capacitance for the phono stage. Up to a maximum of 1000pF.
• Signal-to-Noise Ratio: A value of >80dB indicates that the audio will be excellent.
• Distortion (THD): The percentage of THD is less than 0.02%.
• Dimensions: 206 x 72 x 200 mm
• Weight: 2 kg

Summary of the Project Phono Box RS2

The Phono Box RS2 runs on an external adapter with a power rating of 20V/3A. If you have an amplifier with a 3500x voltage gain and the input sensitivity is in the range of a few hundred micro-volts (0,0001 Volt), you will surely want to keep it as far as possible from any interference sources that are traditionally harmful to the signal from the cartridge.

This is the idea that all elements that can radiate electromagnetic fields must be kept out of the amplifier range. This is why ProJect decided to use an external power supply.

Benchmark for Quality

Thanks to a refined circuit design, select transformers, and filters, the RS2 performs at the peak of its capabilities. The source of any noise and distortion has been revealed and, therefore, corrected. So the sound that one listens to is the intended one.

Money Worth Spending

Purchasing the Phono Box RS2 means investing in the future and the quality of your musical experience with vinyl. The quiet behind the music of the RS2 will make any listener want to hear it over and over again.
