Each input setting is stored in memory. Large ranges from 40dB up to 65dB are possible. 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. Load impedance can be set continuously via potentiometer, a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust the impedance during playback and immediately assess the impact of different load options. This is necessary to find just the right load impedance for your cartridge. No other manufacturer implements this feature in this precise and extreme manner.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Pro-Ject Tube Box DS3 B extreme closeup inserted tube\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/pro-ject-tube-box-ds3-slv-tube.jpg?v=1708530487\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBalanced Signal Transmission\u003c\/h3\u003e\n\u003cp\u003eConnect your turntable either with the 5-pin mini XLR cable or standard XLR cables and profit from a balanced signal transmission. Symmetrical (a.k.a. balanced) transmissions consist of a hot and a cold (+ and -) signal. Both signal chains effectively carry the same musical information. The Tube Box DS3 B can extract the final musical information out of the +\/- signals and remove all noise that was potentially added along the transmission. All components including tube output and polypropylene capacitors are audiophile grade and guarantee a breathtaking sound experience.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced XLR, Interference-Free:\u003c\/strong\u003e A balanced connection can extract the final musical information, effectively filtering out any noise from interferences stemming from our noisy, modern homes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eE88CC Vacuum Tubes:\u003c\/strong\u003e The E88CC tubes perform with low noise and microphonics.
