Description
The Pro-Ject Tube Box DS2 Phono Pre-amplifier benefits from outstanding circuit technology from Dr. Sykora and uses high-quality components. Compatible with both MM and MC cartridges. It offers connection for two turntables plus two selectable line outputs and a continuously variable selection of input impedance for low output MC cartridges while playing a record! Other features include input capacitance for MM cartridges and switchable subsonic, that prevents your amplifier and speakers of ultra low rumble below 20Hz.
Features
- Suitable for MM and MC cartridges
- Precise RIAA equalisation
- Ultra low noise circuitry
- Selection between 2 phono inputs & 2 line outputs
- Dual mono circuitry for optimized channel separation
- Selectable input impedance (for MC: fix or variable)
- Selectable input capacitance (for MM)
- Selectable subsonic filter
- Gold-plated RCA in & outputs
- Sandwich alu/metal casing protects from vibrations and electromagnetic interference
