DAC Symphony
Dramatically reduced the level of digital noise.
Reduced impact of interconnect.
Special power supplies provide a very clean and smooth power.
2 types of digital filters - linearphase and minimum phase.
2 S/PDIF and/or AES/EBU inputs.
Input impedance of 75 ohms or 110 ohms.
Input data word lenght from 16 to 24bit.
Sampling frequency from 32 to 192 kHz.
Automatically switches and displays the sampling frequency.
Stereo analog outputs true-balanced (XLR) or unbalanced (RCA).
Output impedance 600 ohms.
Output voltage 1.7 V rms.
Frequency range 15-45000Hz (-3dB).
Dynamic range > 120dB.
Distortion <0.001%.
Out-of-band noise (50kHz-100MHz) <-90dB.
Power supply AC 220V/50Hz or DC 12V.
Very small size and weight.
