Norma Audio HS DA1 DAC konverter

Modular in its conception, it is available in two versions: single DAC and DAC PRE. In the DAC configurations, it has five digital inputs, one of which is USB, one AES EBU XLR and Three Spdf 1 inputs, one of which can be configured as a digital output from the CD reading mechanism. In the DAC PRE version, it adds very advanced analog pre-amplification section to the DAC features, and has two analog inputs in addition to the 5 digital inputs. The preamplifier stage can operate both in active and passive mode: in active mode, the gain can be easily varied, even via remote control, between X and Y decibels (for active and passive mode, see the notes on Revo SC-2 LN). HS DA-1 also features an output for twoo headphones: the output drive is low impedance, so that any type of headphones can be managed in the best possible way. To optimally adapt to the different sensitivites of the headphones models, the gain and the output level can be chosen among X values. In addition, the user can set a defferent reference level for the RCA output and the headphone output, in order to normalize all levels when switching line/headphone.
Conceived to be very compact and modular, the HS DA-1 combines remarkable operationalversatility with the exclusive and original Norma sound.
