The table shows a most important technical characteristics of Audiolab M-DAC Sharp Rolloff
*Center channel headphone is received by averaging between left and right channels
Test conditions
- Measured by RAA with ADC from E-MU1616m
- Difference ... 0 dBFS out level Audiolab M-DAC Sharp Rolloff versus ADC E-MU1616m 0 dBFS input level is -8,63 dB (value level for left and right channels)
- During tests RAA measuring complex was used galvanic isolated power transformer and was excluded the effect of ground loop in the spectra
- The signal was tested from output: RCA
- The signal level while playing: Maximum level
- The bit depth of the test signal: PCM 24 bit
- Source of test signal: USB
