3.5mm headphone jack: Line/headphone output
The headphone output is automatically selected for audio output if no external Sony/Philips Digital Interface Format (S/PDIF) optical digital output device is detected. The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of44.1kHz or 48kHz, or 96kHz. The headphone output volume can be adjusted from 0.0dB to -43.0dB.
During playback of a 1kHz sine wave at -3dBFS voltage level, 24-bit sample depth, 44.1kHz output sample rate, 100k load (unless otherwise specified), the audio output has the following nominal specifications:
Jack type: 3.5 mm (1/8-inch) stereo combo
Maximum output voltage: 1.4VRMS (+5.15dBu)
Output impedance: <24 ohms
Frequency response: 20Hz to 20kHz, +0.5dB/-3dB
Signal-to-noise ratio (SNR): >90dB
Total harmonic distortion + noise (THD+N): <-80dB (0.007%)
Channel separation: >85dB
3.5mm headphone jack: S/PDIF optical digital output
The S/PDIF optical digital output is automatically selected when an S/PDIF optical digital output device is detected on the external combination audio port. The S/PDIF optical digital output supports pulse-code modulation (PCM) and Arc Consistency Algorithm #3 (AC-3) audio formats with the following stereo data stream characteristics:
PCM: 16, 20, or 24 bits per sample at sample rates of 44.1kHz or 48kHz, or 96kHz
AC-3: 16 bits per sample at sample rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz
The S/PDIF optical output channel status conforms to International Electrotechnical Commission (IEC) 60958-3 consumer mode digital audio.
During playback of a 1kHz sine wave (S/PDIF output format at 0 dBFS output level, 44.1kHz sample rate, 24-bit sample depth, unless otherwise specified), the digital audio output has the following nominal specifications:
Jack type: 3.5 mm (1/8-inch) stereo combo
Digital audio signal-to-noise ratio (SNR): >130dB
Digital audio total harmonic distortion + noise (THD+N): <-130dB (0.00003%)
