Modular in its conception, the HS DAC1 is available in two versions: single DAC and DAC PRE.
HS DA-1 also features an output for two 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 sensitivities of the headphones models, the gain and the output level can be chosen among X values. In addition, the user can set a different 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 operational versatility with the exclusive and original Norma sound.
Black finish is also available for additional fee.
