For small DAW studio setups, portable laptop editing or mixing rigs, or just pure playback enjoyment, the m900 provides the same analog and DAC quality as our large monitor controllers, but in a rugged, portable and surprisingly affordable unit.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe m900 DAC uses the latest generation AKM 4490 chip, which features 32-bit processing and supports sample rates up to 384kHz PC or 256x DSD. The USB interface operates in asynchronous mode allowing the m900 to be the clock master which makes the system immune to USB bus jitter. S\/PDIF and Toslink inputs allow the m900 to enhance to any DAW interface with true reference quality D\/A conversion, headphone monitoring and stereo speaker control.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAn intelligent power supply design allows for two power operation modes - LOW and HIGH. LOW power mode is from USB connector #1, which provides bus power along with data, allowing the m900 to operate from a single connection to your computer. HIGH power power mode is available by connecting the included 2A USB DC power supply to the USB connector #2, which provides additional power harder to drive headphones.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eTransimpedance amplifier topology coupled to a zero ohm output impedance driver provides headphone performance that is incredibly spacious and transparent with a tight, enveloping low end. Our latest generation crossfeed circuit rounds out the design by simulating an acoustic listening environment in the headphones. Familiar tracks become new again with surprise details, while audio production tasks like tracking, mixing and editing happen faster and easier.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAfter many years of honing our DAC and headphone amplifier designs, the m900 distills the best of what we've learned in a compact, rugged and simple unit. Whether in the studio, on your desk or on the road, the m900 will bring you closer to the music you love.\u003c\/p\u003e\n\u003cdiv class=\"webtext__column webtext--text\"\u003e\n\u003ch2\u003eGrace Design M900 Features:\u003c\/h2\u003e\n\u003cul class=\"webtext-block--colcount\"\u003e\n\u003cli\u003e\u003cstrong\u003e2-ch headphone amplifier and top-shelf D\/A converter\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePortable bus-powered unit is ideal for travel, desktop, or studio\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eJitter-free computer audio playback with support for up to 32-bit\/384kHz PCM and 256x DSD\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDual zero-ohm output impedance headphone outputs deliver spacious and transparent performance\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eStereo unbalanced analog outputs make connecting to your stereo monitor system easy\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible with a wide variety of digital sources via USB, TOSlink, and S\/PDIF coax\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e4 different DAC filter settings provide personalized playback\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSimple setup menu and easy-to-read 7-segment LED display\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eLarge rotary encoder for easy volume control and menu navigation\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"Tabs1\" class=\"ui-tabs ui-widget ui-widget-content ui-corner-all\"\u003e\n\u003cul class=\"ui-tabs-anchor\" role=\"presentation\" href=\"http:\/\/www.gracedesign.com\/products\/m900\/m900.html#tabs-4\" id=\"ui-id-1\" tabindex=\"-1\"\u003e\u003c\/ul\u003e\n\u003cdiv id=\"tabs-4\" aria-labelledby=\"ui-id-1\" class=\"ui-tabs-panel ui-widget-content ui-corner-bottom\" role=\"tabpanel\" aria-expanded=\"true\" aria-hidden=\"false\"\u003e\n\u003cli class=\"bullets\"\u003eUSB, S\/PDIF and Toslink digital inputs, supports up to 192kHz (Toslink up to 96kHz)\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eAsynchronous USB interface for jitter free computer audio playback, supports up to 384kHz PCM and 256x DSD\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eDual zero ohm output impedance headphone outputs\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eUnbalanced level controlled outputs via RCA for connecting to a stereo monitor system\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eCompact, portable chassis perfect for travel, desktop or studio\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eLow power mode via USB Bus power\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eHigh power mode via included USB 2A power supply\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003e4 different DAC filter settings to tailor playback performance to personal preference\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eSimple user setup menu for setup and calibration\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003e7 segment LED display displays level and setup menu information\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eLarge rotary encoder for volume control and setup menu navigation\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003eMade in Lyons, CO USA\u003c\/li\u003e\n\u003cli class=\"bullets\"\u003e5 year transferable Warranty\u003c\/li\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Grace Design","offers":[{"title":"Default Title","offer_id":55426086273406,"sku":null,"price":412.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0179\/7585\/products\/m900_front.jpg?v=1620843841","url":"https:\/\/www.asapeurope.com\/products\/grace-design-m900-compact-portable-headphone-amp-dac-preamp-special","provider":"ASAP EUROPE LONDON, UK 020 8672 6618","version":"1.0","type":"link"}
