Audiophile tube warmth The Tube Box S3 B is a audiophile phono preamplifier that brings true analog warmth to your vinyl playback. It features a fully symmetrical and discrete gain stage, balanced 5-pin mini XLR input, and balanced XLR outputs. Cartridge loading options Large ranges from 40dB up to 65dB are possible. A fully balanced design makes all the difference here. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your HiFi system, matching the volume levels accurately to other sources like CD players or streaming devices. The loading options for MM and MC are designed so that the widest array of cartridges will work perfectly with the Phono Box S3 B. Ultra low values like 50 pF or 10 ohms allow you to account for special situations, for example sub-ideal higher capacitance cables. Each input settings are stored in the memory. The Tube Box S3 B always has you fully covered. "B" stands for balanced The symmetrical design is the real standout feature! Connect your turntable with the 5-pin mini XLR cable & profit of the balanced signal path. Symmetrical, or also called balanced, transmissions consist of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A true balanced gain stage can now extract the final musical information out of the +/- signals and subtract, remove, all noise that could potentially be added along the transmission. As there are two separate signal chains, we also needed two individual amplifier sections. Definitely unseen in this price range & the best and cleanest amplifier for your phono signal! Tube assembly: 2x ECC83 (12AX7) Input impedance: 10, 50, 100, 1k, 47k ohms Input capacitance: 50, 150, 300, 400 pF Gain (+ 6dB using XLR Out sockets): 40, 45, 60, 65 dB Signal / Noise ratio MM (40dB): 97dBV, 105dBV - 'A' weighted Signal / Noise ratio MC (60dB): 83dBV, 88dBV - 'A' weighted THD at 1 kHz:
