Description Tube Box E The Pro-Ject Tube Box E brings classic tube warmth to your turntable setup in a sleek, miniature form. The all-metal enclosure shields against unwanted interference, while the finely-machined aluminium front panel adds a touch of sophistication. Available in silver or black, Tube Box E blends seamlessly into any hi-fi system. Pure Analogue Performance Inside, a fully discrete circuit design avoids operational amplifiers (OpAmps), resulting in ultra-low noise and accurate RIAA equalisation. This means your records sound clearer and more natural, with lush mids and a relaxed tonal character. Dual mono circuitry enhances channel separation, delivering a more immersive stereo image. Flexible Features Supporting both MM and MC cartridges, the Tube Box E offers front panel gain control and a subsonic filter to reduce rumble. Loading options are easily adjustable underneath, allowing precise matching to your cartridge. Replaceable ECC83 tubes invite sound-shaping through tube rolling, giving you control over your audio signature. Features Precise passive / active RIAA equalisation. Fully discreet circuit design without OpAmps. Ultra low noise circuitry with FET input stage. Well-filtrated high-voltage anode power supply. MM / MC Compatibility. Dual-mono electrical design.
