Know before you buy
No, the Phono Box RS2 features a fully discrete hardware design that completely avoids the use of op-amps. This approach is intended to provide a more natural, dynamic, and transparent sound profile.
Yes, the unit is fully compatible with both MM and MC cartridges. It offers adjustable gain settings and variable input impedance to ensure optimal performance regardless of your cartridge type.
The Phono Box RS2 features unique continuously variable input impedance loading and channel balance controls. These allow you to fine-tune the electrical load to perfectly match the requirements of your specific cartridge for the most accurate playback.
Yes, the device is equipped with both balanced XLR and unbalanced RCA inputs and outputs. Using the balanced XLR connections can help reduce noise and interference in your audio chain.
The inclusion of passive DECCA equalization allows you to correctly play back older vinyl records mastered with the Decca curve, which differs from the standard RIAA equalization used for modern records.
Yes, the robust metal chassis is designed to shield the internal circuitry from electromagnetic interference and minimize mechanical vibrations, both of which are essential for maintaining a low noise floor.
