Description
Hyvä ääni kuuluu kaikille.
High End Stereo power amplifier, 2 x 160 W, balanced, tube design,
Recent test success in issue 1-2025 of Hifimaailma magazine.
"HIFI WORLD 1-2025 TEST COMMENT"
"Sonically, the Amp Box RS2 was clearly in the minds of both listeners. It managed to serve the music faithfully to its origins but still with a certain personality. When you also take into account the impressive measurement results, the Amp Box RS2 can be safely recommended to anyone looking for a compact but good-sounding amplifier."
The new Amp Box RS2 features a state-of-the-art reference power amplifier. It delivers three-dimensional sound quality, perfect microdynamics and extreme resolution combined with high power. The fully discrete Class AB amplifier design combines the advantages of both technologies and offers better accuracy, low distortion and high efficiency.
The Amp Box RS2 operates as a stereo amplifier or can be connected in bridge mode, in which case it functions as a single mono power amplifier. It meets the highest audio standards in terms of spatial perception and microdynamics, offering excellent sound reproduction. Like the Pro-Ject RS products, the Amp Box RS2 also features a reference-class tube buffer input stage. The luxurious full-metal housing is not only an eye-catcher, but also important for the cooling of the product. The amplifier is available in a silver or black finish.
Clean and stable power is essential for every HiFi setup. The included power supply is already a good base, but the Pro-Ject Power Box RS2 Amp goes even further. A linear power supply consists of a large toroidal transformer with shielding between the primary and secondary windings, which acts as an isolation transformer and prevents interference from the mains from penetrating the amplifier. This transformer has a large power reserve compared to a conventional power supply.
• Fully discrete circuit design
• Powerful 160W Peak per channel at 4ohms (stereo)
• 350W Peak in mono bridged configuration
• Extreme dynamic power
• Up to 25% more power with Power Box RS2 Amp
• Tube buffer stage with reference quality
• Balanced XLR & single-ended RCA inputs
• High quality gold plated speaker terminals
• RS232 control
• Full metal casing protects against vibration & interferences
• Available in silver or black
• Upgrade linear power supply available separately
• Made in Europe
- Bridged: 280W / 8 ohms (1% THD)
- Bridged: 350W / 8 ohms (1% THD)
