{"product_id":"rockna-wavedream-signature-dac","title":"Rockna Wavedream Signature DAC","description":"\u003cp\u003eThe Wavedream Signature is the higher of the two versions of Rockna's Wavedream D\/A converter, fitted with the company's RD-0 conversion modules — discrete sign-magnitude hybrid ladder DACs with a 27-bit structure, each driven by its own FPGA and capable of sample rates up to 6MHz. The entire digital section lives on a single FPGA, so firmware updates change the hardware architecture itself, and the Femtovox clock system synthesizes the conversion clock directly at the DAC input with around 300 femtoseconds of jitter. Custom 16x Parks-McClellan upsampling filters offer linear, minimum, and hybrid phase responses, the class A output stage is built entirely from through-hole JFET and bipolar devices, and a 256-step volume control allows direct connection to a power amplifier.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eD\/A conversion\u003c\/th\u003e\n\u003ctd\u003eRD-0 discrete sign-magnitude hybrid ladder modules, 27-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eClock\u003c\/th\u003e\n\u003ctd\u003eFemtovox, conversion clock synthesized at the DAC input, ~300fs jitter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003ePerformance\u003c\/th\u003e\n\u003ctd\u003eTHD+N -102dB (0.0008% at -6dB), S\/N 132dB, dynamic range 132dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eMax output\u003c\/th\u003e\n\u003ctd\u003e10Vpp SE, 20Vpp XLR; 256-step volume, 0.5dB steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eDigital inputs\u003c\/th\u003e\n\u003ctd\u003eS\/PDIF, AES\/EBU, USB (32-bit\/384k PCM, DSD64-512), 2x HD-Link (LVDS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:1.5em\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e440 x 360 x 90mm, 7.8kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eAbsoulute is a proud \u003ca href=\"\/collections\/rockna-audio\"\u003eauthorized Rockna Audio dealer\u003c\/a\u003e.\u003c\/strong\u003e Call or visit the showroom about availability, pricing, or a private demo — \u003ca href=\"\/pages\/contact\"\u003eget in touch\u003c\/a\u003e.\u003c\/p\u003e","brand":"Rockna Audio","offers":[{"title":"Default Title","offer_id":48285989306594,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/9190\/0130\/files\/wdream_persp-1.jpg?v=1788036844","url":"https:\/\/absouluteav.com\/products\/rockna-wavedream-signature-dac","provider":"Absoulute AV","version":"1.0","type":"link"}
