Note: For best results, headphones or other low-impedance devices should not be plugged into
the line-out jack. Such devices should be plugged into the front panel headphone jack.
Note: For best results, equipment plugged into the line-out jack should not connect the audio
ground to other grounds, such as the chassis or “green wire” ground.
Based on a 1 kHz, -1 dBFS sine wave playback, 24-bit 44.1 kHz output format, -3 db output level and 100 kilohm
load no weighting (unless otherwise specified below) , the line output has the following electrical characteristics
(nominal specifications):
output voltage (full-scale output): 1.4 Vrms (+5.1 dBu)
output impedance: <50 ohms
bits per sample: 16-bit or 24-bit
channel separation: > 65 dB
THD+N (total harmonic distortion plus noise): < –78dB (0.0125%) no weighting
frequency response: 20 Hz to 20 kHz, +0.5 dB/–3.0 dB
