The SE300<\/strong> comes supplied with an R-2R DAC, instead of a Delta-Sigma DAC that is most commonly used in other audio players. R-2R DAC, also known as Ladder DAC, as it arranges resistors in a ladder form, offers natural yet dynamic Hi-Fi sounds, but it is extremely technical and difficult to execute as it requires complex refined resistor units and hard to manage current controls. However, despite these technical challenges, after several years for development and a lot of trial and error we have managed to overcome this and create a new analog sound. In the process, we have meticulously selected each and every one of the 96 ultra-precision resistors and finalized our R-2R DAC technology.<\/p>\n SE300<\/strong> takes us one step closer to realizing analog sound from a digital source and is the result of a long journey taken by Astell&Kern<\/strong> with uncompromising craftsmanship to find the ultimate sound solution.<\/p>\n The R-2R DAC within the SE300<\/strong> arranges 48 pairs (23xR and 25x2R) of 96 ultra-precision resistors to create analog signals, in turn realizing true Hi-Fi 24-bit decoding.<\/p>\n It is key to total the accurate current value with resistors that has the smallest error ranges in order to create Hi-Fi sound with an R-2R DAC. To realize this, Astell&Kern<\/strong> inspected each specifically selected ultra-precision resistor of 0.01% error range to complete the design of SE300<\/strong>.<\/p>\n To create Hi-Fi sound without distortions within such an extreme precision design, we analyzed and preconceived any potential impacts that may be caused by changes in temperature. The SE300<\/strong> comes with special *TCR10 specifications to minimize the changes in the 0.01% resistor error range.<\/p>\n The SE300<\/strong> comes with a Dual AMP mode. Class A amplification that creates low distortions and natural sounds and a Class AB amplification that plays dynamic sounds with high efficiency so users can pick and choose from the two amps according to their listening preferences and genre of music that they are playing.<\/p>\n Experience the true sounds that only Astell&Kern<\/strong> can deliver with the SE300<\/strong> that comes with an R-2R DAC and Class A\/AB Dual AMPs born from Astell&Kern\u2019s<\/strong> unique proprietary designs that reduces power consumption whilst enhancing output and removing noise.<\/p>\n For seamless use of sensitive IEMs and hard to drive headphones, a device must provide suitable output, respective of the connected device\u2019s specification.<\/p>\n The SE300<\/strong> supports a 2-step Gain Level mode to create the prefect match for a wide range of headphones and IEMs, maintaining an optimal sound output. The two-step gain setting with \u201cNormal\u201d and \u201cHigh Gain\u201d modes can generate a high current output to create a powerful sound and excellent driver control. With up to 6 Vrms from the balanced connections, driving high-impedance headphones has never been easier.<\/p>\n <\/p>\n SE300<\/strong>, the fourth model in the A&futura<\/strong> range is a premium digital audio player that inherits this identity and expands the scope of sound with an entirely new implemented technology. A&futura SE300<\/strong> is equipped with an ultra-refined R-2R DAC, Class A\/AB dual amps born with our proprietary TERATON ALPHA technology, and for the first time a self-developed FPGA optimized technology. With these unrivaled components, it offers the true sound philosophy and technology of Astell&Kern<\/strong>.<\/p>\n","protected":false},"featured_media":38565,"template":"","meta":{"_acf_changed":false},"product_brand":[733],"product_cat":[383],"product_tag":[],"class_list":{"0":"post-38563","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-astell-kern","7":"product_cat-portable-music-players","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"acf":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38563","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":1,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38563\/revisions"}],"predecessor-version":[{"id":49410,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product\/38563\/revisions\/49410"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/media\/38565"}],"wp:attachment":[{"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/media?parent=38563"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_brand?post=38563"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_cat?post=38563"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/hifimarket.ee\/ru\/wp-json\/wp\/v2\/product_tag?post=38563"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Realization of 24-bit Decoding with R-2R DAC<\/h4>\n
