DAC(Digital til Analog konverter)

Arcam rDAC

 

Arcam var det første firma til at lancere en ekstern Digital/Analog Converter (DAC), kort efter den første CD afspiller blev præsenteret tilbage i midt firserne. Resultatet var en dramatisk forbedring af lydkvaliteten.

I de seneste år har streaming af musik gjort eksterne DACs enormt populære og det har fået Arcam til at understrege deres kompetence inden for denne produktgruppe, med deres nye rDAC.

Det slanke aluminums chassis skjuler den seneste inden for digital konverterings teknologi og der benyttes B.la. den fremragende 8741 IC fra Wolfson Microelectronics. Der tilbydes tre input, coaxial, optisk og USB og alle tre har forbløffende præcision og stor musikalitet.

Copland DAC 215

 

Universal high resolution DAC, pre-amplifier, headphone amplifier

The digital revolution has made music easily accessible. Thanks to the convenience and impressive sound quality of computer sourced digital music files, many audiophiles consider their personal computer or laptop as their primary audio source. Connected to a computer the DA215 will process audio data of extremely high resolution and the playback quality will be defined mainly by the data itself.

DA215 serves excellent DAC with multiple S / PDIF inputs and support PCM / DSD signals, built on chips ES9018 Reference 32-bit DAC configuration quad-mono, ie 8 mono channels are converted into 2 stereo. When combining the four-phase and antiphase four converter per channel, the statistical properties of the signals are improved; correlating the power signal phase subsequently added, while as the noise power is uncorrelated in phase - thereby improving signal / noise ratio of the resultant analog waveform. 

Analog circuits and filters built on discrete elements. Technology circuit class-A was borrowed from a well-established CD-player Copland and provides stunning sound quality with a relaxed mobility and dynamics. Due to the increase of the sampling frequency, sampling reduces the influence on the outputs of DACs. This allows the construction of the analogue output stage with high bandwidth and low-order analog filters. 

DA215 has an asynchronous USB input, three digital inputs S / PDIF, analog inputs, two analog outputs (fixed and adjustable), headphone output on the front panel, on which work weekends tube drivers class-A, as well as a built-in preamp with an analog volume control. In the pure functional DAC preamp and volume control can be turned off.
