Power Requirement
  90 - 230 V AC

Power Consumption
  Stand-By: < 1 W
in use: 35 W

Analog In- and Outputs
  2 Cinch inputs L/R
2 Cinch outputs L/R
2 XLR outputs L/R (asymmetrical)
analog inputs (converted A/D with 24 Bit/96 KHz)
analog outputs (converted D/A with 24 Bit/96 KHz)
when using the S/PDIF output with analog inputs, the sampling rate is always 24 Bit/96 KHz.
signal-to-noise ratio A/D converter 92 dB(A)
signal-to-noise ratio D/A converter 98 dB(A)
input level +2 dbV / +8 dBV / +14 dbV, switchable
output level +12 dbV (without correction, bypass)
output level +6 dbV (with typical correction)
controllable with the remote control in 0.5 dB steps
signal source resistance Ri = 120 Ohm
1 microphon input 6.3 mm phone jack for measurement (measurement done by audiodata)

Digital In- and Outputs
  3 S/PDIF coaxial inputs (Cinch)
supported sampling rates: 44.1 KHz, 48 KHz, 88.2 KHz, 96 KHz
1 S/PDIF coaxial output (Cinch) 24 Bit/up to 96 KHz
controllable with the remote control in 0.5 dB steps
when using the S/PDIF output, the sampling rate is on par with the sampling rate at the respective S/PDIF input
resolution up to 24 Bit at all sampling rates
1 USB input (for restoring the optimizers and for software-updates)

  1 Ethernet connector (RJ45) for network player functionality in a UPnP/DLNA compatible home network (server - controller - renderer)
supported are all popular music file formats up to 24 bits/192 KHz (as of firmware version V3.4)
Matching streaming firmware is optional for new devices, can be upgraded via firmware update for older devices (since summer 2009)

Signal Processing
  signal processing with 24 Bit/96 KHz when using the analog input
with the respective sampling rate of the S/PDIF input
with up to 24 Bit/192 KHz as a network player via the Ethernet jack
frequency resolution over the whole audio-range 0.6 Hz
temporal resolution over the whole audio-range 22 µs
four parallel working, independent Convolverr
internal accuracy of calculation continuous 64 Bit Double Precision
highest audio quality by abdication of sampling rate conversion
mastering to 24 Bit output signal with HP TPDF Dither
maximum of clarity by digital volume control before processing HP TPDF Dither
