Sixteen input channels with signal-present LEDs, mono buttons for pairs 1-2 and 9-10, and three original coloring circuits give a tonal range running from clean, reference-grade summing to the heavily driven character of vintage analog consoles.\u003c\/p\u003e\n\n\u003ch3\u003eActive versus passive summing: why it actually matters\u003c\/h3\u003e\n\u003cp\u003eA common belief holds that passive summing boxes — simple resistor networks with an amplifier making up the lost level — are more transparent because they lack active electronics. Chris Muth points to two real problems with that approach: no common-mode rejection, which is key to low noise, and no isolation between a D\/A converter's ground and the summing circuit's ground, which leads to poor crosstalk rejection and blurred stereo imaging. The 2-BUS+'s active design gives the inputs a local ground reference shared with the summing amplifier, resulting in clean, quiet, stable summing — measurable, not just a marketing claim.\u003c\/p\u003e\n\n\u003ch3\u003eThree analog coloring circuits, none of them fixed\u003c\/h3\u003e\n\u003cp\u003eHarmonics is an odd- and even-order distortion generator running parallel to the clean signal — it subtly warms the top end and thickens the bottom, useful for example to bring out backing vocals without raising their level or sibilance. Paralimit is a FET limiter \"set to stun,\" inspired by the classic 1176 \"all buttons in\" trick, delivering instant stereo parallel compression without building a complex outboard patch and manually matching levels. X-Former is a pair of custom-wound Cinemag transformers with a proprietary core-overdrive circuit, delivering the solid, punchy sound of older analog consoles. Harmonics and Paralimit can be assigned to the whole mix or separately to channel pairs 13-14 and 15-16, with their order in the chain reversible and blended back with the dry signal via a knob — X-Former always sits in the mix bus path. A switchable stereo insert placed after all the coloring circuits lets you patch in external outboard at the very end of the chain.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSixteen-channel active analog summing\u003c\/li\u003e\n\u003cli\u003eSignal-present LED for every channel\u003c\/li\u003e\n\u003cli\u003eMono buttons for channel pairs 1-2 and 9-10\u003c\/li\u003e\n\u003cli\u003eHarmonics circuit: odd- and even-order distortion generator\u003c\/li\u003e\n\u003cli\u003eParalimit circuit: FET limiter, stereo parallel compression\u003c\/li\u003e\n\u003cli\u003eX-Former circuit: a pair of Cinemag transformers with core overdrive\u003c\/li\u003e\n\u003cli\u003eHarmonics and Paralimit assignable to the mix or channel pairs 13-14\/15-16, reversible order\u003c\/li\u003e\n\u003cli\u003eSwitchable stereo insert on the mix bus\u003c\/li\u003e\n\u003cli\u003eStepped output level control: -4 to +6dB in 0.5dB steps\u003c\/li\u003e\n\u003cli\u003eInputs on XLR and D-sub connectors, main and monitor outputs on XLR\u003c\/li\u003e\n\u003cli\u003eHand-built in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum input level: greater than +28dBu\u003c\/li\u003e\n\u003cli\u003eTHD+N at +4dBu (1kHz, unweighted, 22Hz-22kHz): below 0.0048%\u003c\/li\u003e\n\u003cli\u003eTHD+N at +22dBu: below 0.0026%\u003c\/li\u003e\n\u003cli\u003eIMD at +4dBu: below 0.0038%, IMD at +22dBu: below 0.0021%\u003c\/li\u003e\n\u003cli\u003eCrosstalk rejection: greater than 108dB at 1kHz\u003c\/li\u003e\n\u003cli\u003eNoise at unity gain (22Hz-22kHz): below -86dBu\u003c\/li\u003e\n\u003cli\u003eNoise at nominal mix setting (22Hz-22kHz): below -91dBu\u003c\/li\u003e\n\u003cli\u003eFrequency response: flat within 0.1dB from 10Hz to 50kHz\u003c\/li\u003e\n\u003cli\u003eInput impedance: 25k Ohms, balanced\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 50 Ohms, balanced\u003c\/li\u003e\n\u003cli\u003eInputs: 2x DB-25, 2x XLR; outputs: 2x XLR main, 2x XLR monitor; insert: 2x XLR send\/return\u003c\/li\u003e\n\u003cli\u003eDimensions: 3.5 x 19\" (2U)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Dangerous Music","offers":[{"title":"Default Title","offer_id":54195222315345,"sku":"25545","price":3575.47,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/DangerousMusic2BUS_1.jpg?v=1783607739","url":"https:\/\/wrdtunes.com\/en-fr\/products\/dangerous-music-2-bus","provider":"Wired Tunes","version":"1.0","type":"link"}
