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
