Now, the new Tube Box DS3 B adds balanced in- and outputs to the beloved tube amplification. This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components. You can connect two turntables at the same time \u0026amp; easily set everything on the front plate. Each input settings are stored in the 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 loading options. This is necessary to find just the right load impedance for your cartridge. No other manufacturers implement this feature in this extreme way.\" - Pro-Ject\u003c\/p\u003e\n\u003ch4\u003e🔎TECH SPECS\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003etubes: 2 x E88CC \/ 6922\u003c\/li\u003e\n\u003cli\u003einput impedance: stepless 10-1000 Ohms, fix 47 kOhms\u003c\/li\u003e\n\u003cli\u003ecapacitance: 50 \/ 150 \/ 300 \/ 400 pF\u003c\/li\u003e\n\u003cli\u003einput gain: 40 \/ 45 \/ 50 \/ 55 \/ 60 \/ 65 dB\u003c\/li\u003e\n\u003cli\u003enoise floor: \u0026gt;87dBV - ‚A‘ weighted\u003c\/li\u003e\n\u003cli\u003eTHD: \u0026lt; 0,03%\u003c\/li\u003e\n\u003cli\u003eRIAA EQ Curve Accuracy: +\/- 0,5dB\/20Hz - 20kHz\u003c\/li\u003e\n\u003cli\u003einputs: 1x 5-pin mini XLR \/ 1x pair XLR \/ 1x pair RCA phono\u003c\/li\u003e\n\u003cli\u003eoutputs: 1x pair RCA, 1x pair XLR\u003c\/li\u003e\n\u003cli\u003eoutput voltage:18V\/1000mA DC\u003c\/li\u003e\n\u003cli\u003edimensions (WHD): 8.11\" x 3.54\" x 8.94” \/ 206 x 70 x 194 mm\u003c\/li\u003e\n\u003cli\u003eweight: 3.44 lbs \/ 1560 g \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e📦COMES WITH\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2x E88CC tubes\u003c\/li\u003e\n\u003cli\u003epower supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eABOUT TRUE BALANCED AUDIO\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eTrue Balanced Audio refers to a superior audio signal that results in higher sound quality with nearly zero background noise, check out our in-depth guide \u003ca rel=\"noopener\" href=\"https:\/\/www.turntablelab.mom\/blogs\/guides\/pro-ject-true-balanced-audio-guide\" target=\"_blank\"\u003ehere\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eTrue Balanced gear can be utilized as both balanced (with the proper components and signal path) or non-balanced\u003c\/li\u003e\n\u003cli\u003eTrue Balanced Audio requires a moving coil cartridge (MC) or the Pro-Ject Pick it Pro Balanced MM Cartridge\u003c\/li\u003e\n\u003cli\u003eTrue Balanced Audio requires a balanced audio cable (5-Pin DIN, mini XLR \/ XLR, or RCA \u0026gt; Mini XLR) connected from the turntable to the preamp\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTrue Balanced Audio requires a preamp that accepts balanced cables; you can output either XLR (recommended) or RCA from the preamp to speakers \/ amplifier\u003c\/li\u003e\n\u003cli\u003eshop all \u003ca href=\"https:\/\/www.turntablelab.mom\/collections\/pro-ject-true-balanced-audio\" rel=\"noopener\" target=\"_blank\"\u003ePro-Ject True Balanced\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pro-Ject","offers":[{"title":"Black","offer_id":41499220443226,"sku":"eq-1900-black","price":1099.0,"currency_code":"USD","in_stock":false},{"title":"Silver","offer_id":41499220475994,"sku":"eq-1899-silver","price":1099.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0105\/4542\/files\/pro-ject-tube-box-ds3-b-phono-preamp-black.jpg?v=1762286170","url":"https:\/\/www.turntablelab.mom\/products\/pro-ject-tube-box-ds3-b-phono-preamp","provider":"turntablelab.mom","version":"1.0","type":"link"}
