Its performance coupled with its deep feature set and sonic customizability make it nearly unbeatable as a DAC\/Amp combo from a feature perspective. Set all that aside, and at its core DAC502 is about more than just turning the 0s and 1s from digital audio back into the sound waves they represent, but actually reaching back to recapture the original performance and deliver it to your ears.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/bloomaudio.mom\/blogs\/articles\/weiss-dac502-review\" title=\"Weiss DAC502 Review\"\u003eRead the full review.\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eFrom Weiss\u003c\/h3\u003e\n\u003cp\u003eThe DAC502 MK2 is a state of the art D\/A Converter with an unprecedented level of sophistication and versatility. The MK2 version delivers a higher level of sonic performance than the older DAC502.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003eA typical D\/A Converter is a \"set and forget\" device. Not so with the DAC502 MK2. It adds a number of interesting signal processing features and sports a variety of digital inputs. Balanced, unbalanced and headphone outputs are provided. \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003eWeiss Engineering has a 30 year history in D\/A Converter design. In that time span we have learned a thing or two about converter design. The DAC502 MK2 is the essence of our experiences.\u003c\/p\u003e\n\u003ch3\u003eNew and Improved\u003c\/h3\u003e\n\u003cp\u003eThe MK2 versions use the latest DAC chips with stellar technical specifications, making for an enhanced two channel DAC with improved transparency and openness. Both line output stages and headphone output stages are built with Weiss’ proprietary discrete electronics.\u003c\/p\u003e\n\u003cp\u003eBoth units incorporate a stainless steel chassis with a robust 10mm aluminum faceplate. Digital processing is performed by a pair of 32-bit ESS Sabre DAC chips per channel, providing superb channel separation and noise-rejection in both two and four channel applications.\u003c\/p\u003e\n\u003cp\u003eWhat’s most significant, however, is the unit’s analog stage, whose new discrete operational amplifiers are of the utmost importance. These “discrete operational amplifiers” are called OP2-BP, and are designed and produced by Weiss. Their performance far exceeds commonly-available monolithic op-amp chips, and contribute to Helios’ extraordinary sound quality and unmatched signal to noise ratio of 128 dB.\u003c\/p\u003e\n\u003cp\u003eThe Weiss DAC 501\/502 MK2 share the same circuitry and componentry, and differ primarily in form-factor: the DAC501 MK2 is a compact, half-width unit, allowing placement flexibility in desktop and studio applications, as well as in home systems of any size. The DAC502 MK2 features a standard, full-width chassis; it also differs from the 501 by including a four-pin balanced headphone connector on the back of the enclosure.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/DAC502_PERSP_B_2048x2048.jpg?v=1649703309\" alt=\"Weiss DAC502\"\u003e\u003c\/p\u003e\n\u003ch3\u003ePower Supply\u003c\/h3\u003e\n\u003cp\u003eA powerful non-switching power supply is used. All sensitive voltages have their own regulators which are separated between left and right channels. The result is an analog output free of “digital noise” and channel crosstalk. The power switch activates a semiconductor relay which only switches on or off at zero crossings of the mains voltage. This assures a glitch free power switching. The two mains transformers are toroidal types. Mains voltage selection is done automatically by measuring the mains voltage before power is applied to the rest of the electronics.\u003c\/p\u003e\n\u003ch3\u003eSynchronization\u003c\/h3\u003e\n\u003cp\u003eAn internal high precision \/ low jitter clock generator is responsible for clocking the D\/A converter section. The sampling frequency of that generator is fixed at about 195kHz. The input signals are converted to the 195kHz sampling frequency for optimal signal quality. This scheme also helps significantly in reducing any jitter related effects. All standard sampling frequencies up to 384 kHz plus DSD x64 and x128 are supported.\u003c\/p\u003e\n\u003ch3\u003eDigital Inputs\u003c\/h3\u003e\n\u003cp\u003eThere are a total of five inputs:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAES\/EBU or S\/PDIF via XLR, Toslink and RCA sockets\u003c\/li\u003e\n\u003cli\u003eUPnP \/ DLNA via Ethernet\u003c\/li\u003e\n\u003cli\u003eUSB\u003c\/li\u003e\n\u003cli\u003eRoon Ready\u003c\/li\u003e\n\u003cli\u003eAccepted formats: PCM 44.1kHz up to 384 kHz, DSD 64x \/ 128x.\u003c\/li\u003e\n\u003cli\u003eFuture formats can be accommodated for via software updates.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/DAC502_FRONT_B_2048x2048.jpg?v=1649703334\" alt=\"Weiss DAC502\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSignal Processing\u003c\/h3\u003e\n\u003cp\u003eThe DAC50x has a digital signal processing chip built in (DSP).\u003cbr\u003eThe following DSP algorithms are currently implemented:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRoom Equalizer - to suppress room modes for a decent bass reproduction.\u003c\/li\u003e\n\u003cli\u003eCreative Equalizer - a tone control with low boost\/cut, high boost\/cut and mid boost\/cut.

Dummy head recordings usually are listened to via headphones because they only work properly if the left channel goes to the left ear only and the right channel to the right ear only. With speakers this is difficult to achive as the left channel goes to the left and the right ear. But with some clever signal processing of the speaker channels is is possible to suppress the crosstalk, i.e. the audio going from the left speaker to the right ear and vice versa. If that works properly then the recording sounds as if one would be in the space where the recording has taken place. All the reverberation and 3D representation of the sound sources is there.(For speaker based playback only.)\u003c\/li\u003e\n\u003cli\u003eLoudness Control - a listening volume dependent equalization of the audio.\u003c\/li\u003e\n\u003cli\u003eHeadphone Equalizer - to adapt any headphone to the listener's ears in terms of frequency response.\u003c\/li\u003e\n\u003cli\u003eCrossfeed - to emulate a speaker based playback impression on headphones.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConverters\u003c\/h3\u003e\n\u003cp\u003eTwo of the latest 32 bit D\/A Converter chips are used.
