Pro-Ject PJ71658588 Tube Box S2 Phono Pre-Amplifier – Black
The Pro-Ject PJ71658588 Tube Box S2 is our very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to his preference. Tube Box S2 will give a full and relaxed laid back sound with lush mids, just like you would expect it from a much bigger high end tube phono pre-amplifier.
It offers support for both MM and MC cartridges. It also comes with many gain settings on the front panel. Five variable input impedance settings are available to adjust to any MM cartridge, the 47k ohm input impedance setting is fixed and suited for high output MC cartridges. The Pro-Ject PJ71658588 aluminium/metal casing is adapted to our DS2 line in looks and lastly, protects against vibrations and electromagnetic interferences for superior sound.
The Subsonic filter helps to reduce low-frequency rumble and wasted amplifier power. The Subsonic filter button is located on the front-panel.
