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 and comes with many gain settings to be switched 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 aluminium/metal casing is adapted to our DS2 line in looks and protects against vibrations and electromagnetic interferences for superior sound.Type: Phono PreamplifierUK/EU Power supply included: YesInputs: RCAOutputs: RCAColour: SilverElectronics: ECC83Width (cm): 13.1Height (cm): 7.3Depth (cm): 10.3Bluetooth: NoControls: SubsonicControls: GainGain: 40 dBGain: 43 dBGain: 50 dBGain: 60 dBGain: 63 dBInput Impedance: 10 OhmInput Impedance: 100 OhmInput Impedance: 1 kOhmInput Impedance: 2 kOhmPackage Contents: AdapterRIAA-Equalisation Curve Accuracy: 0.4 dB / 20 Hz - 20 kHzTHD: 0.02%THD: 0.05%USB: NoWeight: 410 gMade in: Czech RepublicPower Supply: AdapterOriginal Colour by Producer: Silver
