Audio line input/optical digital audio input port
Line input
The analog line input operates independently from all other audio input ports and is always available. The line input supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the line input is presented as a stereo data stream. You can adjust the line input gain from -16 dB to +30 dB.
During input of a 1 kHz, 1 VRMS (-3 dBFS) sine wave (44.1 kHz input sample rate, 24-bit sample depth, 0.0 dB input gain, no weighting) the audio line input has the following nominal specifications:
Jack type: 3.5 mm (1/8-inch) stereo
Maximum input voltage: 3 VRMS (+11.8 dBu)
Minimum voltage input for full scale output: 63 mVRMS (-21.5 dBu) at input gain = +30 dB
Input impedance: > 20 kilohm
Frequency response: 20 Hz to 20 kHz, +0.5 dB/-3 dB
Signal-to-noise ratio (SNR): >90 dB
Total harmonic distortion + noise (THD+N): <-85 dB (0.006%)
Channel separation: > 85 dB
