Spdf takes advantage of these often unused ports, providing a digital interconnection between a computer and eurorack system.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe module accepts a 2-channel S\/PDIF signal at the Rx jack (via coaxial digital cable) and converts it into two discrete analog signals available at the OUT 1 and OUT 2 jacks. Conversely, Spdf accepts two discrete analog signals at the IN 1 and IN 2 jacks and converts them into a 2-channel S\/PDIF signal available at the Tx jack.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe most common configuration uses a bi-directional digital interconnection. The audio interface must have both S\/PDIF In and Out ports, and the module is set to external sample clock sync.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cem data-mce-fragment=\"1\"\u003eNOTE: With the SYNC switch set to EX, the blue EXT SYNC LED will illuminate when a valid sample clock is detected at Rx.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eA uni-directional digital connection is used if the audio interface has only a S\/PDIF In port.

This includes keyboards and samplers, DJ mixers and multi-player decks, digital speakers, and consumer electronics such as TVs, stereo systems, CD players and more.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cem data-mce-fragment=\"1\"\u003eIMPORTANT: Use digital coaxial cables (75 Ω) for optimal signal transmission, not regular RCA audio cables.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eAnalog I\/O\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe module’s analog inputs and outputs are DC-coupled (selectable for inputs), which means Spdf can encode and decode DC signals like control voltages. When used in conjunction with software such as Bitwig Studio or Ableton CV Tools, the module can be used to send and receive control voltages like 1V\/oct pitch signals, gates, triggers, LFOs, ADSRs, and other modulators.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eSpdf can also be used to digitally encode and decode audio signals. AC-coupling for the inputs may be selected (default setting), which will enable an inaudible high-pass filter to remove any DC offset prior to S\/PDIF encoding.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAll i\/o circuitry has been carefully designed and routed for low-noise performance, with buffered inputs and outputs scaled to accept eurorack signals up to ±10 V.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSynchronization Settings\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eSpdf will operate only when locked to sample clock of 44.1 kHz or 48 kHz, either from an external source (S\/PDIF Rx signal) or internally generated. Three DIP switches on the back of the module may be used to configure these settings, as well as to select DC or AC coupling of the inputs.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdl\u003e\n\u003cdt\u003eDimensions\u003c\/dt\u003e\n\u003cdd\u003e5 HP\u003c\/dd\u003e\n\u003cdd\u003e25 mm deep\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdl\u003e\n\u003cdt\u003eCurrent Draw\u003c\/dt\u003e\n\u003cdd\u003e55 mA +12V\u003c\/dd\u003e\n\u003cdd\u003e10 mA -12V\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e","brand":"BOREDBRAIN","offers":[{"title":"Default Title","offer_id":42096210313389,"sku":"","price":169.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/products\/boredbrain_spdf.jpg?v=1676136031","url":"https:\/\/www.detroitmodular.live\/products\/boredbrain-spdf","provider":"Detroit Modular","version":"1.0","type":"link"}
