This technology makes the finest details audible thanks to its low-distortion architecture.\u003cbr\u003eIt supports sampling frequencies up to 768kHz PCM (16x CD resolution) and DSD (Direct Stream Digital) playback up to\u003cbr\u003eDSD4 or DSD256 (11.2 MHz) resolution. This qualifies the Phonitor One d for the currently highest resolution audio playback.\u003c\/p\u003e\n\u003cp\u003eThe USB connection is Class Compliant. This means that all Mac computers and iOS devices like iPads and iPhones can use the full performance bandwidth of the DA-converter without driver installation. iOS devices require the camera adapter. For Windows a driver is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Revolution\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe revolution in the headphone amplifier is the Phonitor Matrix – mixes made on headphones sound as they were mixed on speakers. The Phonitor Matrix in its largest expansion stage has three setting parameters: Crossfeed, Speaker Angle and Center Level.\u003c\/p\u003e\n\u003cp\u003eIn the Phonitor One, the center level is preset to -1 dB and the speaker angle to 30°. These are the most commonly used values. The crossfeed function determines the crosstalk of the channels, the so-called interaural level difference. The intensity of the crossfeed is fully variable. When the Crossfeed control is in the OFF-position the Phonitor Matrix is switched off – it is removed out off the audio signal path via relay (hysteresis circuit).\u003c\/p\u003e","brand":"SPL","offers":[{"title":"Default Title","offer_id":33151195447373,"sku":"SPLPHON1-D\/1902","price":1099.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0085\/8118\/5613\/products\/d17c58c10ec5d3b0784c9a1638234bd3.jpg?v=1676405822","url":"https:\/\/musiccitycanada.com\/products\/spl-phonitor-one-d-headphone-monitoring-amplifier","provider":"Music City Canada","version":"1.0","type":"link"}
