  Measurements

  Measurements taken at the following conditions (unless otherwise noticed): +17 dBu output level, 0 dBFS input level, 48 kHz sampling frequency (fs), 22 kHz measurement bandwidth.

   

  Frequency Response:

  DC…20 kHz: ±0.3 dB

   

  THD+N at 1 kHz:

  At −3 dBFS input: −97 dB

   

  SNR at −20 dBFS input:

  107dB unweighted, relative to full scale output

   

  Linearity:

  From 0 dBFS to −120 dBFS input level: less than ±1 dB deviation from ideal

   

  Crosstalk:

  Less than −110 dB, DC…20 kHz

   

  Inter-channel phase response:

  Less than ±0.5°, DC…20 kHz
