Pro-Ject Tube Box S2 – turntableredtube amplifier
Pro-Ject Tube Box S2 is an innovative turntable predMini-sized amplifier with tube output and top quality sound!
The Tube Box S2 uses a fully discrete circuit design without operational amplifiers (OpAmps). It has interchangeable electronic tubes, allowing for easy customization with different types of tubes to change the sound.
Offering a wide range of sound choices and customization options, the Tube Box S2 delivers a rich, relaxed and naturally warm sound with distinct sredwith tones like you would expect from a larger, top-of-the-line tube turntable.redamplifier.
It supports MM (moving magnet) and MC (moving coil) heads, and has aredadjustable signal gain on the control panel.
Five adjustable input impedances allow adaptation to any MM cartridge, while the 47 kΩ input impedance is fixed and suitable for high-output MC cartridges.
The aluminum/metal housing is designed to match our DS2 series and offers effective protection againstred vibrations and electromagnetic interference for superior sound quality.
Compatible nadbuilt-in power supply: Accu Box
